[0031] [0031] The following description and drawings are illustrative and should not be construed as limiting. Several specific details are described to provide a complete understanding. However, in certain examples, well-known or conventional details are not described in order to avoid obscuring the description. References to one or a modality in the present disclosure are not necessarily references to the same modality; and, such references mean at least one.
[0032] [0032] A lifting board (also called a lifting device or a hydrofoil board / device) is a vessel device that includes a surfboard (also called a board) and a hydrofoil that is attached to the board and extends below the board into the water during operation. The hydrofoil generates ascent, which causes the board to rise above a surface of a body of water at higher speeds. The present disclosure provides jet hydrofoils that represent a vessel device that includes a hydrofoil board (i.e., a board with a hydrofoil attached below the surface of the board) and an electric propeller system (ie, a powered propeller system) using an electric motor) that powers the vessel device. Jet hydrofoils can also be called electric hydrofoil devices. Jet hydrofoils introduce hydrofoil sports to a wide audience by providing a quiet alternative for personal gas powered craft, a more effective non-drive alternative for craft without aerodynamic lift, and / or a windless or low wind option for individuals to use devices. hydrofoil for recreation. Consequently, a method and system, according to the present disclosure, provides a jet hydrofoil comprising a board, a hydrofoil coupled to the board, and an electric propeller system coupled to the hydrofoil to power the jet hydrofoil. The hydrofoil can be released from the board using a quick release when not in use to allow the operator to store or move the jet hydrofoil more easily. A jet hydrofoil operator can use a weight shift mechanism or other mechanism with the use of a controller to control both a speed and direction of the jet hydrofoil. In this way, the jet hydrofoil is a personal electrically powered surfboard that uses hydrofoils and is safe, easy to drive and easy to transport.
[0033] [0033] FIG. 1 illustrates an example of a portion of a jet hydrofoil 100, according to implementations of the present disclosure. Jet hydrofoil 100 includes a board 102, a hydrofoil 104 attached to board 102, a propulsion module 106 attached to hydrofoil 104, a propeller 108 attached to propulsion module 106, and a propeller guard 110 surrounding the propeller 108. In some implementations, jet hydrofoil 100 includes propeller 108 without propeller guard 110. When board 102 floats on a surface of a body of water (for example, a lake or ocean), hydrofoil 104 is submerged under the surface of the water body (that is, hydrofoil 104 is in the water body). When the jet hydrofoil 100 reaches a sufficient or predetermined speed, the rise generated by the hydrofoil 104 raises the board 102 over the surface of the water body. Therefore, hydrofoil 104 provides rise to jet hydrofoil 100. Jet hydrofoil 100 can include a variety of hydrofoil combinations including, but not limited to, hydrofoil 104 alone, rather than a hydrofoil, and a hydrofoil coupled with a canard . Board 102 may have quick connectors to facilitate removal / release of hydrofoil 104 from board 102.
[0034] [0034] An operator (also called driver or user) of jet hydrofoil 100 can be on a top surface of board 102 in an upright position and can use a controller (not shown) attached to board 102 to control the jet hydrofoil 100. The controller can also be called an accelerator controller. Board 102 can serve as a flotation device and includes a front section, an intermediate section and a rear section. The longitudinal and directional control of the jet hydrofoil 100 can be controlled by the operator using any of the weight shifts, coupling with the controller (for example, the operator who moves a lever or handle to the right, thus turning the jet hydrofoil 100 in the right direction), and using predetermined routes (for example, the operator who inserts a route before operating the jet hydrofoil 100 and the jet hydrofoil 100 automatically that follows such a trajectory with the use of GPS coordinates). In addition, the stability of the jet hydrofoil 100 can be controlled by the operator using any of the weight shifts, engage with the controller (for example, the operator who clicks a button to rebalance and stabilize the jet hydrofoil 100 around a sudden turn), and with the use of another device embedded in the jet hydrofoil 100 (for example, a MEMS device that includes, but is not limited to, a gyroscope).
[0035] [0035] The operator can also be arranged on the top surface of board 102 in the prone or kneeling position (in addition to the upright position). Jet hydrofoil 100 can also be operated while the operator is seated on board 102 or while the operator is seated on a chair positioned on or attached to the top surface of board 102. The propulsion module 106 can include or accommodate a power 112 which can receive instructions from the controller (ie based on the use of the controller operator) to power propellant 108 (for example, using a power system motor 112), thereby serving as a propulsion system to operate the jet hydrofoil 100. The supply system 112 may include, but is not limited to, any engine, a motor controller (eg electronic speed control (ESC)), a battery system and a cooling system. The supply system 112 can be completely housed in the propulsion module 106 and is shown in FIG. 1 for illustrative purposes. The feeding system 112 can feed the propeller 108 through an axis using electrical power from an engine (for example, an electric motor) to generate thrust, which causes the jet hydrofoil 100 to gain speed in the surface of the water body. The controller may comprise an accelerator that controls the speed of the jet hydrofoil 100 by means of the supply system 112 by adjusting the thrust generated by the thruster 108.
[0036] [0036] Hydrofoil 104 may comprise a plurality of components which include, but are not limited to, a tie 114, a stern wing 116 and a bow wing
[0037] [0037] In some embodiments, the rod fixing mechanism is a gripping mechanism that includes two compatible plastic parts to form a socket connection, where one of the two compatible plastic parts fits into the rod 114, and the other between the two compatible plastic parts fit on the board 102. The one of the plastic parts (for example, the side part of the board) can be attached with O-rings, so that when the two compatible plastic parts are compatible to form a fixture , where fixation prevents water intrusion. Sealed spring loaded electrical connectors (for example, three bullet connectors) can fit into dedicated compartments on the two compatible plastic parts. One half of each connector can fit into the side plastic part of the board and the corresponding half can fit into the side plastic part of the tie rod. The sealed spring loaded electrical connectors can be attached to wires on the board 102 and on the rod 114, respectively. When attached, the sealed spring loaded electrical connectors can form the continuous wire path from board 102 to drive module 106.
[0038] [0038] The tie rod mechanism can also be designed with a hinge mechanism, in which the user would fit an edge of the top of the tie rod 114 into the hinge mechanism at the bottom of the board 102. This allows the user to rotate the tie rod 114 vertically where it would snap into place using a locking mechanism (for example, a latch lock). To allow a hinge mechanism to serve as the tie rod mechanism, the electrical connectors are shaped differently from a bullet shape, so that they can fit into sockets (for example, blade fin sockets).
[0039] [0039] The rod 114 can connect the board 102 to the propulsion module 106 and both the stern wing 116 and the bow wing 118 can be coupled to the propulsion module 106. The stern wing 116 and the bow wing 118 can be attached. collectively referred to as 116-118 hydrofoil wings. Propulsion module 106 can be positioned in front of rod 114, at the stern of rod 114, or centered around rod 114. Positioning of propulsion module 106 facing rod 114 will affect the position of propeller 108 facing rod 114, and can affect the position of the hydrofoil wings 116-118 if they are attached to the propulsion module 106. The stern wings and bow wings 116-118 can also be attached to a horizontal fuselage which is attached to the tie rod 114 (for example, above propulsion module 106 or near a lower end of rod 114 which is below propulsion module 106) as opposed to indirectly through propulsion module 106. The stern wings and bow wings 116-118 can be attached to any one of a bottom surface, a top surface and an intermediate section (between the bottom and top surface) of the propulsion module 106. In some implementations, the wings aft and bow wings 116-118 are coupled to the bottom surface of propulsion module 106; therefore, hydrofoil 104 includes a structure that does not integrate the stern wings and bow wings 116-118 with the propulsion module 106. The riser 114 can be connected to the plank 102 by means of a riser slit that provides an opening both on a bottom surface and on a top surface of plank 102 in a similar location. The tie groove may vary in shape and size and may comprise a thin rectangular line opening. The rod 114 can be a vertical rod with similar dimensions (for example, rectangular shape) or variant dimensions (for example, tapered shape) between the upper and lower ends.
[0040] [0040] The stern and bow wings 116-118 can be horizontal wings that extend from both sides of the propulsion module 106. The stern and bow wings 116-118 (and any other wings attached to the module propulsion systems 106) can include a variety of sizes and designs (for example, different curved flaps, rudder wings that protrude from the edges, etc.) to allow customization of the jet hydrofoil 100 according to the levels of experience and desires operator. The stern and bow wings 116-118 can be fixed components of hydrofoil 104 or the stern and bow wings 116-118 can be or can contain mobile structures that are controlled by a jet hydrofoil operator 100 (e.g. controlled using the controller). In addition, other components of hydrofoil 104 can be movable or repositionable using the controller. For example, tie rod 114 or propulsion module 106 can be moved to different positions with varying angles. The operator can move various components of hydrofoil 104 that includes the stern wings and bow wings 116-118 based on varying conditions that include, but are not limited to, level of experience and performance requirements.
[0041] [0041] The propulsion module 106 is an underwater housing used to integrate a propulsion system (i.e., a system comprising at least the propeller 108 and part of the supply system 112) on the rod 114 to provide a combined component. The propulsion system can also be called a propellant system. The combined component can be manufactured to have a continuous housing made of carbon fiber, aluminum, or other similar material. The combined component can provide both the housing of the propulsion module 106 and the rod 114, therefore reducing parts, assembly effort and manufacturing costs while increasing structural integrity. Propulsion module 106 can also be detachable from rod 114 to allow the two parts (i.e., propulsion module 106 and rod 114) to be manufactured more easily (for example, in separate factories and quickly assembled or disassembled for repair) ). The aft and bow wings 116-118 can be attached to the propulsion module 106 by means of a plurality of mechanisms that include, but are not limited to, removable screws. The propulsion module 106 can accommodate an engine and other components (e.g., engine controller, battery, etc.) of the power system 112 and can also act as a spacer between the stern and bow wings 116-118.
[0042] [0042] In some implementations, the propulsion module 106 can be integrated in the rod 114 above a horizontal part (for example, a fuselage) of hydrofoil 104; therefore, the engine and other components of the supply system 112 are housed elsewhere in the propulsion module 106 (i.e., the supply system 112 is not housed in the propulsion module 106). In another implementation, parts of the supply system 112, which include a motor and a gearbox (if a gearbox is used) and, optionally, a motor controller (for example, an ESC) are housed in the control module. propulsion 106, while the battery system or batteries are housed elsewhere (for example, on board 102). In other implementations, propulsion module 106 is a separate component that can be attached and detached from rod 114 (i.e., propulsion module 106 and rod 114 are not a continuous combined component) to allow propulsion module 106 be transported to a charging station / location to change or charge a battery from the supply system 112 stored in the propulsion module 106 without also having to transport the tie rod 114 and / or the entire jet hydrofoil 100 to the charging station / location .
[0043] [0043] Board 102 may be the light weight, low drag platform that is longer than wide (ie, a length of board 102 is greater than a width of board 102). Board 102 may be made of a floating material (for example, polyurethane or polystyrene foam or a similar type of foam covered with layers of fiberglass or carbon fabric or a similar type of fabric and a polyester resin or resin epoxy or a similar type of resin) that is designed to provide the operator with a place to stand when jet hydrofoil 100 is in use. In some implementations, the board 102 includes a design format that works with both hydrofoil 104 and the unique characteristics of the operator (for example, level of knowledge, height, weight, etc.). For example, plank 102 can include a beginner shape that is wide, more buoyant, and does not include a planing mode, or plank 102 can include an advanced shape that is smaller, not buoyant enough for the operator to stand on the plank 102 while stationary, and includes a planing mode.
[0044] [0044] In some implementations, the board 102 includes a design format (or is shaped) so that the drag curves versus speed of the board 102 in displacement mode (or without aerodynamic lift), aerodynamic lift mode, and when applicable, planing mode, are complementary,
[0045] [0045] When board 102 is in contact with the surface of the water body to obtain buoyancy (for example, when the operator is about to depart), jet hydrofoil 100 is in a non-aerodynamic (or displacement) mode . When plank 102 is above the surface of the water body and does not float from the water (for example, when the operator is operating jet hydrofoil 100), jet hydrofoil 100 is in an aerodynamic lift mode. When jet hydrofoil 100 is partially sustained by the rise generated by plank 102 that glides at a certain speed on the surface of the water body and before reaching another speed that puts jet hydrofoil 100 in aerodynamic lift mode, jet hydrofoil 100 is in a planing mode. Vessels (for example, boats) that are designed to glide at low speeds include a planed hull design that allows vessels to partially lift out of the water when sufficient power is provided. The plank 102 can be shaped / designed in a similar way to have a design shape with a planing hull for planing mode. In some implementations, the board 102 can provide enough buoyancy to support the operator's full weight during non-aerodynamic lift mode.
[0046] [0046] The design format of plank 102 and wing collision of jet hydrofoil 100 can be configured so that a float center of jet hydrofoil 100 in non-aerodynamic lift mode and a center of rise from hydrofoil wings 116-118 in aerodynamic lift mode are aligned or substantially aligned. In other words, an upward force generated by a float of the board 102 when the board 102 is in contact with a body of water (for example, the board 102 is in displacement or mode without aerodynamic lift) centered in approximately the same position and in the same direction (for example, in the forward / aft direction) as an upward force from the rise generated by hydrofoil wings 116-118 when plank 102 is in aerodynamic elevation (eg plank 102 is in mode aerodynamic lift). Therefore, the shape and composition of the board 102 is related to the position of the hydrofoil wings 116-118 to provide an alignment that is compatible with the center of buoyancy at the center of ascent.
[0047] [0047] The alignment between the center of buoyancy and the center of rise means that minimal repositioning is required for the operator to maintain stability during the mode transition (that is, the jet hydrofoil operator 100 does not need to change the positioning of or substantially redistribute your weight as a transition from non-aerodynamic lift mode to aerodynamic lift mode or from aerodynamic lift mode to non-aerodynamic lift mode, etc.), making jet hydrofoil 100 easier to conduct. In addition, the operator does not need to sit or lie on board 102 to transition from non-aerodynamic lift to aerodynamic lift mode. The positioning of hydrofoil wings 116-118 will determine the positioning of the lift center when the jet hydrofoil 100 is in aerodynamic lift mode and will determine the ideal body position for the operator when plank 102 is in aerodynamic lift mode.
[0048] [0048] The jet hydrofoil 100 may include a variety of features to provide increased safety during operation that include, but are not limited to, safety shutdowns, speed limitations, and sensor data collection and analysis. For example, jet hydrofoil 100 may include a magnetic emergency switch attached to the ankle to provide an additional level of safety (in addition to a level of safety determined from the operator who has the ability to release or release the accelerator) if the operator falls into the body of water during operation (ie, the jet hydrofoil 100 can shut down when the operator falls into the water with the emergency switch that was released from the jet hydrofoil 100). Jet hydrofoil 100 can also be configured to provide engine braking when an emergency switch strip (for example, the magnetic emergency switch attached to the ankle attached to the operator) is detected by the jet hydrofoil 100 as loose even if the operator has not fallen from the 100 jet hydrofoil.
[0049] [0049] In addition, during normal operation, the jet hydrofoil 100 can be configured to transition from non-aerodynamic lift to aerodynamic lift mode between a predetermined speed (for example, 14.816-18.52 km / h (8-10 we)). The throttle of the jet hydrofoil 100 can be limited to reach a predetermined maximum or peak speed limit (e.g., 27.78 km / h (15 knots) of peak speed) to further improve safety. Smart throttle limiting options can also be implemented to facilitate changing the peak speed limit. For example, the operator can set a beginner experience level that would automatically be below the peak speed limit compared to the upper peak speed limit detected for an operation with an advanced level of experience. The jet hydrofoil 100 can also use a folding propellant (i.e., a propeller system with propeller blades that can fold in multiple positions that includes a collapsed composition that reduces the potential damage from contacting the propeller blades. ) which increases operator safety by collapsing from one position to another when it is not deliberately in use. The jet hydrofoil 100 may have device-specific battery packs (for example, LiFePO4 or LiIon batteries) that further increase the security of the device. The jet hydrofoil 100 can include a variety of sensors to detect data associated with leaks, fallen operators, propellers and / or damaged wings (or other components of the jet hydrofoil 100) and can transmit the detected data to the operator or third parties (eg rental store) to improve the safety and operation of the 100 jet hydrofoil.
[0050] [0050] The jet hydrofoil 100 can include a variety of features to provide easy portability and transport. For example, the board 102 can be made of a carbon fiber material that keeps the jet hydrofoil 100 light. The jet hydrofoil 100 can include batteries in the supply system 112 which are reduced in size and / or weight which also contribute to a lighter weight. A hydrofoil (for example, hydrofoil 104) of jet hydrofoil 100 may comprise a simple hydrofoil that has a vertical rod (for example, rod 114) and two horizontal wings (the stern and bow wings 116-118) for provide lift with the use of a streamlined structure that makes the jet hydrofoil 100 easy for one or two people to transport and launch into the water for takeoff. Alternatively, the hydrofoil of the jet hydrofoil 100 may include a structure which is more complex than the hydrofoil 104 and which comprises a plurality of rods and a plurality of wings in addition to a stern wing and a bow wing which are coupled together in a variety of positions and formats.
[0051] [0051] In addition, the jet hydrofoil 100 can also use a detachable wing design that allows the jet hydrofoil 100 to be made smaller so that it can be packaged in a transport device for transport. The plank 102 of the jet hydrofoil 100 can also be made of an inflatable material to make it easy to transport when the plank 102 is reduced in size when it is in its deflated state. Board 102 may include one or more retractable or detachable wheels that allow a single person to roll jet hydrofoil 100 along a ground surface (for example, a pier, a boat deck, a beach, etc.). Board 102 may have quick connectors for electronic parts on the board that allow the release of hydrofoil 104 from board 102 (for example, as mentioned earlier with respect to the various tie rod mechanisms). The electronic parts on the board can comprise electronic parts to control the operation / speed of the jet hydrofoil 100 which are stored in cavities that are embedded in the top surface of the board 102.
[0052] [0052] FIG. 2 illustrates a top view of an example of a jet hydrofoil board 200 according to implementations of the present disclosure. The board 200 is a component of the jet hydrofoil (for example, the jet hydrofoil 100 of FIG. 1) that is coupled to a hydrofoil of the jet hydrofoil. The board 200 has dimensions that can include a length that is greater than a width. For example, the length of the board 200 can be approximately 2365 millimeters (mm) and the width of the board 200 can be approximately 698 mm. The board 200 can have symmetrical dimensions so that opposite sides of the board 200 are identical or it can have asymmetric dimensions. The board can have a variety of different shapes and sizes. For example, a jet hydrofoil may include a board that is smaller and shaped for superior performance compared to the board
[0053] [0053] Board 200 may include a variety of different length and width measurements based on varying considerations that include, but are not limited to, the level of experience of a jet hydrofoil operator (for example, larger dimensions for novice operators and smaller dimensions for advanced operators). In one example, for novice operators, plank 200 can be larger in size (that is, plank 200 includes a longer length and a longer width) so that it is easier to stand when not in aerodynamic lift. . In another example, plank 200 may be smaller in size (ie plank 200 includes a shorter length and a smaller width compared to the larger size used for novice operators), thereby improving performance (for example, reduced drag) on board 200, reduced time to transition from non-aerodynamic lift to aerodynamic lift mode, improved power efficiency, etc.) for more advanced operators. The board 200 also includes a thickness that can vary for similar performance requirements (for example, thicker dimensions for novice operators and thinner dimensions for advanced operators). If plank 200 is smaller and / or thinner, plank 200 may include handles to make it easier for the operator to transition from non-aerodynamic lift mode to aerodynamic lift mode while lying down and to stand up once the operator has placed plank 200 in aerodynamic lift mode.
[0054] [0054] A jet hydrofoil (for example, jet hydrofoil 100 of FIG. 1) can be operated by the operator using a controller and can be directed by the operator using weight displacement and foot positioning with relation to a jet hydrofoil board. In addition, the jet hydrofoil may include an optional rudder-type device attached to the board to direct the jet hydrofoil using a mobile steering system. The operator can direct or control the jet hydrofoil using the rudder device by engaging with the controller (for example, by moving a controller handle to the right to direct the jet hydrofoil to the right) or the jet device. rudder type can automatically direct the jet hydrofoil with the use of machine learning mechanisms and sensors that detect various conditions and adjust the jet hydrofoil accordingly (for example, jet hydrofoil sensors recognize that the jet hydrofoil is tilted too far away to the right and thus automatically adjusts the rudder type device to balance the jet hydrofoil by directing the jet hydrofoil to the left).
[0055] [0055] All jet hydrofoils in operation can record a data stream
[0056] [0056] FIG. 3 illustrates a side view of an example of a jet hydrofoil 300, according to implementations of the present disclosure. The jet hydrofoil 300 may be similar to the jet hydrofoil 100 of FIG. 1. The jet hydrofoil 300 includes a board 302 coupled to a tie rod component of a hydrofoil 304. Additional components of hydrofoil 304 (for example, a propulsion module, wings, etc.) are not shown, as they are submerged under a surface of a body of water. On a top surface of plank 302, jet hydrofoil 300 includes at least one foot strip 320 that is used by an operator to operate and to direct jet hydrofoil 300. The operator can direct jet hydrofoil 300 with the use of at least one foot strap 320 in a variety of ways that include, but are not limited to, adjusting the position of your feet with respect to at least one foot strap 320, shifting your weight along board 302, pulling back the hair at least one foot strap 320, and loosen contact with at least one foot strap 320.
[0057] [0057] FIG. 4 illustrates a top view of an example of a jet 400 hydrofoil board according to implementations of the present disclosure. Board 400 is a component of the jet hydrofoil (for example, the jet hydrofoil 100 of FIG. 1) that is coupled to a hydrofoil (for example, hydrofoil 104 of FIG. 1). The board 400 includes a slit 402, a recess 404 that runs from a first cavity (also called a smaller cavity) 406 to a second cavity (also called a larger cavity) 408 and then runs from the larger cavity 408 to the slot cable tie 402. The cable tie slot 402 can be positioned inside / below the larger cavity 408. The larger cavity 408 has a waterproof cover / seal (not shown). The lids can be attached in a variety of ways, for example, with a series of screws attached to seal a gasket, or, alternatively, with a bulb seal locked using a hinge and locking mechanism. When using a hinge mechanism, plank 400 can use a bulb seal made of a variety of materials (for example, rubber and positioned close to a flange embedded in plank 400, outside the carbon fiber and positioned around a cavity outboard, such as the larger cavity 408). The rim can block residual water from entering the stern cavity and also helps to push the bulb seal to ensure that the cover and plank 400 form a watertight fit. The cover can be made out of carbon fiber to be precisely compatible with plank 400. To seal the cover to plank 400, the jet hydrofoil can use a hinge mechanism (for example, two hinges on one side of the cover and one mechanical locking system on the other side of the cover to keep it in place under pressure). Consequently, the cover can form a large part of the surface of the board 400 and can seal tightly (i.e., form a watertight seal) against the board 400 when it is locked.
[0058] [0058] The second cavity 408 (that is, a stern cavity) can be divided into two (or more) compartments to separate the contents of the second cavity 408 (for example, a front compartment for batteries and a stern compartment for others electronic parts). A tunnel can run along the board material between the two compartments to allow wires to connect the electronic parts in the two compartments under the seal of a second cavity 408 lid. The recess 404 between the second cavity 408 and the first cavity 406 also it can be covered or sealed and it can be constructed to include a tunnel between the two 406-408 cavities to allow communication links (for example, wires) to travel between the two 406-408 cavities without any contact with water.
[0059] [0059] The first cavity 406 (ie, a frontal cavity) can include a variety of electronic parts that include, but are not limited to, microcontrollers, an antenna for receiving wireless communications from an accelerator, a display (for example, an LCD display), and a safety emergency switch attachment point (for example, a magnetic attachment point). In versions of the jet hydrofoil that uses a wireless accelerator, there is no junction box required to connect an accelerator cable to the board electronic parts. The first cavity 406 can have a lid, as well as the second cavity 408. The lid of the first cavity 406 can be similar in construction to the lid of the second cavity 408, or it can be made from a transparent material, similar to plexiglass or glass , where it would be valuable for the operator to observe the components inside the cavity (for example, a viewfinder).
[0060] [0060] A deck block 410 that surrounds at least the slit 402, a portion of the recess 404, and the second cavity 408. Deck block 410 can cover other areas of plank 400, which includes covering covers in the second cavity 408 and the tie slit 402, when the second cavity 408 and the tie slit 402 are closed. The 400 board can be made of a variety of materials which includes, but is not limited to, an external carbon fiber material with an internal foam core material. Board 400 can have a variety of dimensions that include, but are not limited to, approximately 2.28 meters x 0.68 meters x 0.12 meters (7.75 feet x 2.25 feet x 0.4 feet). A superior performance board can have dimensions that include, but are not limited to, 1.52 meters x 0.60 meters x 0.15 meters (5 feet x 2 feet x 0.5 feet).
[0061] [0061] Board 400 may also include a heatsink (not shown) on a bottom surface of board 400. The heatsink may be made of a material (for example, aluminum) that is known to have heat-dissipating properties and be in contact with water and / or move air while the jet hydrofoil is in operation. The heat sink uses a material known to be a passive heat exchanger to transfer heat generated by the jet hydrofoil supply system in water or air in order to absorb excessive or unwanted heat generated during the operation of the jet hydrofoil (for example , heat generated by electronic parts or by the feeding system that can be coupled to the 400 board through the first and second cavities 406-408). For example, when board 400 houses certain components that include, but are not limited to, batteries, motor controllers, and motors within any one of the first and second cavities 406-408 instead of housing those components within a system of supplying a hydrofoil propulsion module (for example, supply system 112 of propulsion module 106 of hydrofoil 104 of FIG. 1), then board 400 may include the heat sink to prevent these components from overheating by dissipation heat in the air or water. For example, the heat sink can be made from an aluminum plate embedded in the bottom surface of the board 400, sometimes attached to an adjacent aluminum support to retain a component (for example, the motor controller) that generates heat unwanted. In some implementations, the 400 heatsink is located on the stern of a hydrofoil rod so that the water spray generated by the rod that passes through the water surface (also called rod spray) hits the heat sink, thus , providing additional cooling.
[0062] [0062] The board 400 may include recessed cavities (for example, the first cavity 406 and the second cavity 408) to house electronic parts, such as at least one electronic unit. The first and second 406-408 cavities can be sized and spaced in a variety of shapes, which includes divided into smaller compartments, to accommodate particular needs for electronic parts on the board and a jet hydrofoil operator. The configuration of the first and second cavities 406-408 facilitates the removal of electronic parts (for example, at least one electronic unit) to provide simplified modifications, maintenance and / or improvements to be carried out on the jet hydrofoil and to provide access to a storage unit (for example, memory card) that stores driving data associated with the operation of the jet hydrofoil (for example, GPS coordinates, speed, component health, etc.). In some implementations, a user can access and / or download driving data wirelessly (that is, the storage unit can wirelessly communicate stored driving data), instead of having to remove the electronic unit storage unit.
[0063] [0063] In some implementations, the electronic parts of the board 400 may be attached or incorporated into the board 400 instead of being housed in the first and second cavities 406-408 to inhibit the removal of the electronic parts and provide protection (for example, against water erosion). The second cavity 408 can be located at one third of the stern (1/3) of the board 400, in front of a strip of transom (not shown) and centralized with respect to starboard / port. The recess 404 can be a hollow recess of a predetermined depth to allow a predetermined type of wiring to pass between the first and second cavities 406-408. The recess 404 can also be completely closed, like a tunnel between the two cavities for the link / communication wire to pass. Board 400 may have less than two cavities or more than two cavities in addition to the first and second cavities 406-408. For example, plank 400 may have another cavity that houses an auxiliary battery for emergency use. The auxiliary battery can serve as an additional battery over the battery housed in a hydrofoil propulsion module power system that is attached to the 400 board. As another example, the 400 board can have additional cavities for storing personal items (for example, smart phones) and security items (for example, first aid kit).
[0064] [0064] The slit 402 can be located in the aft quarter (1/4) of board 400. The hydrofoil rod (not shown) can be screwed to the board
[0065] [0065] The recess 404 may not only allow a first wire or cable to turn in front of the electronics unit through the second cavity 408 to the first cavity 406, but it can also allow a second wire or cable to turn aft from from the electronic unit via the second cavity 408 to the tie slit 402. The first and second wires can be a variety of wire types that include, but are not limited to, straight or coiled wires. A junction box can be used to facilitate transitions between electrical wires, which include joining straight or coiled wires. The first wire can allow the accelerator to communicate with an electronic unit (for example, an electronic unit housed in the second cavity 408) via a junction box (for example, a junction box located in the first cavity 406) or directly and without a junction box to adjust the speed of the jet hydrofoil. The second wire can allow the electronics unit to communicate with the power supply system (and associated motor) housed in the hydrofoil propulsion module which is connected via tie rod 402 to a surface below board 400.
[0066] [0066] Therefore, when the accelerator is adjusted (that is, the accelerator is pressed / released to increase / decrease speed) by the operator, the electronic unit (for example, a microcontroller of the electronic unit or a microcontroller that serves as the unit electronic), receive information associated with the adjustment. The information can also first be transmitted to the ideal junction box before being transmitted to the electronics unit. This information can be relayed wirelessly or via a wired connection (for example, a coiled throttle wire that connects the throttle to the junction box or electronics unit directly). The electronic unit then processes the information to generate commands that are transmitted to a motor controller coupled to the motor, thereby adjusting the motor accordingly through the second wire.
[0067] [0067] The first cavity 406 can be located in front of deck block 410 to allow a straight wire (for example, the first wire) instead of the coiled accelerator wire to travel along the recess 404 and to the second cavity 408 The first cavity 406 can be configured to retain or accommodate a junction box that connects a straight wire that runs from the second cavity 408 and through the board 400 through the recess 404 to a coiled accelerator wire that runs to the accelerator (no shown) that is retained by the operator to allow jet hydrofoil operation. In some implementations, the board 400 does not include the first cavity 406 or the junction box housed therein; instead, the accelerator can be directly coupled to an electronic unit housed in the second cavity 408, by a wire or wirelessly, using an antenna. The electronic unit can also be expanded and / or divided, so that some of the electronic parts are housed in the first cavity 406 and some of the electronic parts are housed in the second cavity 408. The electronic unit can include multiple components that include, however without limitation, microcontrollers, emergency switches, displays, junction boxes or similar components, and any other electronic components.
[0068] [0068] The second cavity 408 is sized large enough to hold the electronics unit, and can be sized large enough to hold batteries or a battery system. The electronic unit can be divided into two units, so that some of the components are housed in the first cavity 406 and some in the second cavity 408. The electronic unit can be a variety of types that include, but are not limited to, an electronic unit that comprises at least two microcontrollers, an emergency switch (for example, a magnetic safety emergency switch), and a display (for example, one or more LCD or LED displays). A first electronic unit microcontroller can be used to securely control a board speed 400, by turning the operator's speed input and associated information from an accelerator (for example, a thumb accelerator) maintained by the operator on the controls or in the instructions for a motor controller for a motor of a supply system (for example, the supply system 112 of FIG. 1). The operator can adjust the thumb throttle to adjust the speed (for example, pressing the thumb throttle to increase speed), thereby generating information to adjust the speed of the jet hydrofoil. Information can be received by the first microcontroller that is communicating with the thumb accelerator via an accelerator cable (for example, the coiled accelerator wire), or via a wireless link. The information can then be communicated from the first microcontroller to the motor controller via the first wire or cable that travels from the electronics unit of the second cavity 408 to the first cavity 406, or via another wire or cable when the microcontroller and motor controller are housed in the same cavity, or when the motor controller is housed in the propulsion module. The motor controller can convert the information into commands or instructions that are then communicated by the motor controller to the motor (for example, electric motor, brushless electric motor, etc.) to adjust the speed of the jet hydrofoil. The first microcontroller can also take the input of the emergency switch to adjust (ie, bring to a stop) the speed of the jet hydrofoil.
[0069] [0069] The second microcontroller of the electronic unit can record data on the performance of the jet hydrofoil (or various components of the jet hydrofoil that include, but are not limited to, the engine). The data can be referred to as driving data and can be stored using a storage device (for example, SD card) associated with the electronics unit. The electronics unit may include additional microcontrollers to provide additional functionality that includes, but is not limited to, a microcontroller that acts as a receiver to speak to a microcontroller that acts as a transmitter in a wireless accelerator, a microcontroller that records driving data, a microcontroller that monitors the battery, and a microcontroller that can send and receive communications with a third party device (for example, wireless communications of driving data). The first or second or any additional microcontrollers can be configured to have a variety of functions that include, but are not limited to, speed limitation, changing display options, controlling accelerator curves, etc. The settings of the additional microcontrollers can be made manually or can be adjusted wirelessly (for example, based on a user interface provided through an application on a mobile device, a tablet computer, computer, etc.) . Additional microcontrollers can exist in the jet hydrofoil system outside of board 400, for example, in the accelerator controller, as a wireless transmitter, or in the propulsion module, such as a temperature monitor.
[0070] [0070] The display of the electronic unit can be the variety of displays that includes, but is not limited to, an LCD or LED display. The viewfinder or a separate viewfinder can be located on the accelerator, an optional handlebar attached to both the accelerator and the board, in an optional panel area or additional cavity, or elsewhere in the jet hydrofoil or on a wireless accelerator or wearable viewfinder maintained or worn by the operator. There can be more than one display and the display can be configured to show a variety of information that includes, but is not limited to, battery life status (for example, time until charge is needed), temperature (for example, ambient , water, engine, etc.), battery voltage, current, power percentage of accelerator in use, engine rpm and other information (for example, health of various components, such as the propeller or engine system). For example, the display can provide a low battery alarm, show telemetry, display a message to return to the takeoff location, encourage the driver to drive more effectively or safely (for example, reduce speed), display passcode error, and / or indicate whether or not the jet hydrofoil has activated its emergency stop (letting users know that the jet hydrofoil is not broken, but instead turned off for safety reasons or that the emergency switch was accidentally triggered, etc.).
[0071] [0071] The electronics unit of the second cavity 408 or any other electronic parts on the board that are attached to the board 400 or embedded in the accelerator unit can include a variety of different components. For example, electronic parts on the board may include a Global Positioning System (GPS) or similar location tracking mechanism to record the hydrofoil jet position during operation and / or storage. This information can be used to advise the user when returning to a takeoff position and can be part of the driving data. As another example, components may include electronic parts of sensors or devices that detect leaks, fallen conductors, collisions, improper battery hitches, dirty thrusters and / or low power system efficiency. The jet hydrofoil can be configured to turn off the power system when any of these conditions or any combination of them are detected by the electronics on the board. The electronic parts on the board can include additional components that advise the user on the conditions detected through a plurality of alert mechanisms that include, but are not limited to, sound codes, alarms, vibrations, lights (for example, red flashing light) , text messages, other communication messages (for example, e-mail), or any combination thereof. The alert mechanisms can be displayed through the display of the electronic unit, the 400 board itself, the accelerator, a bracelet worn by the operator, or any other visible area of the jet hydrofoil.
[0072] [0072] Deck block 410 may comprise a rubber lining or similar coating to provide operator stability. For example, deck block 410 can be made from Ethylene Vinyl Acetate (EVA) to provide cushioning and traction for the operator / driver. Deck block 410 can cover the slit 402 and the recess 404 and can also cover the first and / or the second cavities 406-408 when the cavities are closed (e.g. closed with the use of a lid). Deck block 410 can also be placed in other areas. One or more foot strips (for example, at least one foot strip 320 of FIG. 3) are located on board 400 to provide proper driver weight distribution and driver control. Several holes can be drilled on board 400 to allow operators to position one or more foot straps in a way that is suitable for age, height, weight, posture, driving style (for example, regular or amateur), and level operator skill.
[0073] [0073] The emergency switch housed in the first cavity 406 or in the second cavity 408 (or other area of the board 400) can operate as a "dead man switch" which is a physical switch that stops the jet hydrofoil from traveling if the operator falls by means of separates between the emergency switch and a relay. The operator can affix a tape to his ankle so that when it falls from the jet hydrofoil, the tape pulls the emergency switch (for example,
[0074] [0074] In addition to the emergency switch, several hardware and software fail-safe mechanisms can be added to the jet hydrofoil. For example, if the software processed by the electronic units detects a device speed above or below a certain limit that the accelerator controls (for example, the detected speed is above a peak speed limit that the jet hydrofoil should not have the ability to overcome), the software (for example, sending an instruction to the engine via the electronics unit) can shut down or slow down the jet hydrofoil. If the software detects the current when the throttle is not engaged, the jet hydrofoil may be turned off or an error message may be displayed. In another example, if the jet hydrofoil accelerates without extracting the right amount of current or accelerates faster than it can with an operator on the board, the jet hydrofoil can also be turned off or decelerated.
[0075] [0075] FIG. 5 illustrates an example of a first cavity 500 in a jet hydrofoil board according to implementations of the present disclosure. The first cavity 500 can be created or embedded directly on a top surface of the board (for example, the board 400 of FIG. 4). The first cavity 500 houses a junction box 502 which is connected to an accelerator cable 504 that receives input from a jet hydrofoil operator. For example, the operator can engage with (for example, press, release, move a lever, etc.) an accelerator controller attached to the 504 accelerator cable and the information associated with the engaged action is transmitted to the junction box 502. The first cavity 500 is a smaller cavity (e.g., the first / smaller cavity 406 of FIG. 4) compared to a larger cavity (e.g., the second / larger cavity 408 of FIG. 4).
[0076] [0076] The larger cavity can house an electronic unit that can receive the information from the junction box 502 to process, in this way, generate commands or instructions that can then be transmitted to an electric propeller system of the jet hydrofoil to control the operation of the jet hydrofoil. For example, an engine controller (for example, an ESC) that controls an engine in the electric propulsion system can be commanded by the electronics unit to increase the speed of the jet hydrofoil, thereby resulting in the hydrofoil speed increasing at jet through the electric propeller system.
[0077] [0077] FIG. 6 illustrates an example of a second cavity 600 in a jet hydrofoil board according to implementations of the present disclosure. The second cavity 600 can be created directly on a top surface of the board (for example, the board 400 in FIG. 4 and similar to the first cavity 500 in FIG. 5). The second cavity 600 houses an electronic unit 602 that includes a display unit (e.g., LCD or LED) 604, a first communication link 606, a second communication link 608, and a plurality of microcontrollers (not shown). The first and second communication links 606-608 can comprise wires of a plurality of variant types. Fewer or more than two communication links (i.e., the first and the second communication links 606-608) can be housed in the second cavity 600.
[0078] [0078] The first communication link 606 can connect the second cavity 600 to a first cavity (for example, the first cavity 500 of FIG. 5) and can travel along a recess (e.g., recess 404 of FIG. 4) on the deck block (for example, deck block 410 of FIG. 4) of the board. The second communication link 608 can connect the second cavity 600 to a supply system (for example, the supply system 112 of FIG. 1) and can travel along the undercut and through a tie slit (for example, the rod slit 402 of FIG. 4) by means of a rod (e.g., rod 114 of FIG. 1) and the feed system. The second communication link 608 can communicate with a motor controller of the supply system. The first and second communication links 606-608 can also use wireless communications to transmit data between various components of the jet hydrofoil (for example, transmission data between electronics unit 602 of second cavity 600 and a mode motor controller wireless). Therefore, the first and second communication links 606-608 can be wired communication links or wireless communication links.
[0079] [0079] The plurality of microcontrollers may include a first microcontroller to transmit commands that were generated using information received from the accelerator (through operator input). The commands can be transmitted through the second communication link 608 to the motor controller (or other component) of the supply system that processes the received commands and controls or changes the operation (for example, increases / decreases the speed) of the hydrofoil jet. The plurality of microcontrollers can include a second microcontroller to record information (e.g., driving data, run time, routes, component temperature, engine rpm, operator attributes, etc.). The second cavity 600 may include a variety of components which include, but are not limited to, a connector for a foot strip 620 (for example, at least one foot strip 320 of FIG. 3) and an LCD display 604 and a switch emergency 630 that can be attached to the operator (for example, by means of a ribbon / strap or a proximity sensor that captures when a driver has fallen) to stop the operation of the jet hydrofoil when the operator falls off the board. In some implementations, the foot strap 620 and the emergency switch 630 are not coupled to the second cavity 600 and are instead coupled to a first cavity (for example, the first cavity 500 in FIG. 5) or to others plank areas.
[0080] [0080] The jet hydrofoil board can also be made of a material that allows the board to be inflatable. For example, the board can be made using a dropped stitch construction. The board can be inflated using a variety of pumps (for example, self-inflation pump that can be housed in or coupled to the jet hydrofoil) and at a predetermined pressure that includes, but is not limited to, 0.1 MPa (15 pounds per square inch (psi)). An inflatable board may be easier to transport compared to a rigid board (for example, a board made of carbon fiber and / or foam, such as board 102 in FIG. 1 and board 400 in FIG. 4). An inflatable jet hydrofoil board, made of PVC or similar material, can combine the contents of the first and the second cavity in order to accommodate them in the oval, rigid tray made of carbon fiber or a similar material.
[0081] [0081] A jet hydrofoil feeding system (for example, the feeding system 112 of FIG. 1) can be housed, in the propulsion module (as shown in FIG. 1), in the second cavity located on the board, or on a rigid tray (also called a tray) enclosed by an inflatable plank at a top end of a tie (for example, tie 114 of hydrofoil 104 in FIG. 1), thereby allowing the use of a hydrofoil and a system with inflatable boards that have different sizes and shapes and features. The material of the inflatable board may include a predetermined cutout designed to accept the tray that is rigid while the board is inflated. The inflatable board can use an adapter to allow coupling with the hydrofoil (ie, hydrofoil assembly). The adapter can adapt a sharp corner shape of the tray to a rounded elliptical shape that can be more readily incorporated into the inflatable board. A transverse profile of the adapter includes a semicircular internal hollow along its perimeter that allows an inflation pressure of the inflatable board to keep it in place. The tray can be attached to the inflatable board without using the adapter if the tray is pre-shaped with a rounded elliptical shape that is easier to attach to the inflatable board.
[0082] [0082] FIG. 7A illustrates a top view of an example of a jet hydrofoil 700 with an inflatable board 702 according to implementations of the present disclosure. Jet hydrofoil 700 includes inflatable board 702 coupled around a hydrofoil feed system 704. In FIG. 7A, only a top portion of hydrofoil feed system 704 is shown. FIG. 7B illustrates an example of hydrofoil feeding system 704 of jet hydrofoil 700 with inflatable board 702 according to implementations of the present disclosure.
[0083] [0083] The jet hydrofoil 700 can comprise two autonomous components (one for the inflatable board 702 and another for the hydrofoil feeding system 704) that can be coupled together. The jet hydrofoil 700 can also comprise a unique device that includes the inflatable board 702 connected around the hydrofoil feeding system 704. If the jet hydrofoil 700 comprises two stand-alone components, they can be refixed and affixed (for example, when inflatable board 702 is improved or damaged). It may also be possible to detach the hydrofoil feeding system 704 from a tray 706 in a similar manner to the attachment / release of the hydrofoil / rigid board. Unlike inflatable board 702 which includes an inflatable portion and material, hydrofoil feeding system 704 can be a rigid device with tray 706 that can accommodate one or more batteries, part of or the entire feeding system (for example, the power system 112 of FIG. 1), and an electronic unit that includes, but is not limited to, any combination of microcontrollers, an LCD display, a safety emergency switch. A hydrofoil 710 (for example, hydrofoil 104 of FIG. 1) of hydrofoil feed system 704 can be coupled to a bottom surface of tray 706. As shown in FIG. 7B, hydrofoil 710 may comprise a rod, a propulsion module coupled to the rod, at least two wings coupled to the propulsion module, and a propeller system coupled to the propulsion module. The propulsion module can also contain part or all of the supply system. Hydrofoil 710 can also contain a wing instead of two or more wings.
[0084] [0084] Unlike the feeding system 112 of FIG. 1 which is housed in the propulsion module (for example, propulsion module 106), the hydrofoil feeding system 704 feed system can be housed in tray 706. Tray 706 can be coupled to an adapter 708 that surrounds the tray 706 and allows tray 706 to be attached to inflatable board 702. Adapter 708 can have a semicircular internal hollow (or a different type of shape) along its perimeter to allow the inflation pressure of inflatable board 702 to be maintained in place when inflatable board 702 is coupled to hydrofoil feeding system 704 via tray 706 if tray 706 has a sharp corner shape. In some implementations, tray 706 has a semicircular internal hollow and thus the 708 adapter is not required. Tray 706 may include an electronic unit with a display (for example, electronic unit 602 of FIG. 6) and a handle for easy transport. The hydrofoil feeding system 704 (for example, via tray 706) may include an integrated inflation pump that can inflate inflatable board 702. Inflatable board 702 can be inflated before or after coupling together with the inflatable board 702 and the hydrofoil feed system 704.
[0085] [0085] FIG. 8 illustrates an example of a jet hydrofoil 800 with a board with 802 wheels, according to implementations of the present disclosure. The jet hydrofoil 800 includes the 802 wheeled board coupled to a hydrofoil 804 (for example, hydrofoil 104 of FIG. 1). The 802 board can be similar to the board 102 of FIG. 1 or plank 400 of FIG. 4 with the addition of at least one 806 wheel for easy transport. The 802 wheeled board can be dragged or carried by an operator / driver while the 802 wheeled board is turned upside down with hydrofoil 804 in the air, as shown in FIG. 8. In some implementations, at least one wheel 806 comprises a pair of wheels near a perimeter of a top stern portion of the plank with 802 wheels. In other implementations, at least one wheel 806 comprises a single wheel close to a center area of the top stern portion of the plank with 802 wheels. The at least one 806 wheel can be made of a variety of materials (for example, rubber, padded material for beach use, etc.) and can have a variety shapes and sizes and can be positioned on the 802 wheeled board in a variety of locations.
[0086] [0086] The at least one 806 wheel can be inserted into slots embedded in the top stern portion of the 802 wheel plank. The at least one 806 wheel can be removable / detachable or can be incorporated into the 802 wheel plank and thereby mode, not be removable. If at least one 806 wheel is not removable, it can be retractable, so that it can be incorporated into the 802 wheel board and then used when ready for use (i.e., ready to be rolled). If at least one 806 wheel is removable and can be reattached, the at least one 806 wheel can snap into place or can be locked by another mechanism that includes, but is not limited to, gripping.
[0087] [0087] FIG. 9 illustrates an example of a jet hydrofoil 900 controlled using an accelerator system according to implementations of the present disclosure. Jet hydrofoil 900 includes a board 902 (for example, board 102 of FIG. 1 or board 400 of FIG. 4) coupled to a hydrofoil 904 (for example, hydrofoil 104 of FIG. 1). An operator (i.e., driver / user) of the jet hydrofoil 900 can stand upright on board 902 while operating the jet hydrofoil 900 using the accelerator system (also called an accelerator). In FIG. 9, only a portion of the top link of hydrofoil 904 is shown (i.e., the propulsion module, built-in feeding system and propeller system are submerged under water). The accelerator comprises a plurality of components which include, but are not limited to, an operator-maintainable throttle controller 906 and an throttle cable 908 that is coupled to throttle controller 906 at one end and board 902 at the other end. Throttle cable 908 connects throttle controller 906 to board 902 via at least one anchor point 910 (also called throttle and board cable anchor points). The 906 throttle controller may have a variety of controller types that include, but are not limited to, a thumb controller, a trigger controller, a wired controller, a wireless controller (for example, a controller with the ability to communicate wirelessly, and therefore do not use the throttle cable 908), a lever, and any combination thereof.
[0088] [0088] The accelerator can be adapted to be operated by an operator thumb or other finger to control the operation (eg speed, direction, etc.) of the jet hydrofoil 900. When the operator engages (eg presses) the throttle controller 906, the information is produced and the information is transmitted to an electronic unit (for example, via an electronic unit microcontroller) that generates commands or instructions using the information. Before reaching the electronics unit, information can be transmitted from the throttle controller 906 to a junction box (for example, junction box 502 in FIG. 5) that serves as an intermediate device that then transmits the information for the electronic unit. The junction box can be an intermediate transmission device or it can simply connect wires that transmit the information between the 906 accelerator controller and the electronics unit. Information can also be transferred wirelessly from the 906 throttle controller directly (that is, no junction box or similar intermediate device and on the wire throttle cable is required) to the electronics unit. Information can also be transferred in a wired format from the 906 throttle controller directly (no junction box or similar intermediate device is required) to the electronics via the optional 908 throttle cable. In response to the generation of commands or instructions using the information received, the electronics unit transmits the commands or instructions to an engine controller to control the operation of the 900 jet hydrofoil. Therefore, the 900 jet hydrofoil is controlled using operator inputs that are received by the 906 throttle controller. For example, if the operator presses a down arrow button on the 906 throttle controller or presses a back dial to slow down the speed of the 900 jet hydrofoil, the information associated with that action is transmitted to the electronic unit and then processed in a “deceleration command” which is transmitted to decelerate the mo tor.
[0089] [0089] The 906 accelerator controller can be similar to an electric bicyclic accelerator. The throttle controller 906 can be attached to board 902 via throttle cable 908 to a location on a front third (1/3) of board 902. The operator can also use throttle cable 908 for stability while driving. The 908 throttle cable can be designed with no wire junction and as a continuous wire that is directly soldered to a 906 throttle controller sensor, thereby avoiding shorts or water intrusion that would affect the various inputs (for example, input speed) provided by the operator.
[0090] [0090] The wires can serve with a communication link from the accelerator controller 906 via the accelerator cable 908 and to the microcontroller of the electronics unit (for example, the first microcontroller of the electronics unit 602 of FIG. 6). For example, a wire can be embedded in or integrated into the throttle cable 908 and can transmit information from the throttle controller 906 to the junction box in a cavity in the 902 board and then another wire can connect to the junction box to the electronic unit with the junction box that serves as a connection between the two wires. The microcontroller can translate the information received into commands or instructions which are then transmitted to a motor controller (for example, an ESC or motor controller of an electric motor from the power supply 112 of FIG. 1) to operate the hydrofoil jet 900. The throttle cable 908 can connect the throttle controller 906 directly to the electronics unit for processing the information that generates the commands or instructions used by the engine, thereby circumventing the need for the junction box. In some implementations, the information produced by the throttle controller 906 in response to operator interaction (for example, the driver pressing on the throttle controller 906) can be communicated wirelessly indirectly to a microcontroller in the electronics unit and then to the motor controller or directly to the motor controller. In the case of wireless communication, an additional microcontroller that functions as a transmitter would be housed in the 906 accelerator controller.
[0091] [0091] In some implementations, the throttle controller 906 is on a reel belt that allows it to be retracted onto the 902 board and prevents it from being lost. The throttle can be limited to using up to a predetermined percentage (for example, 75%) of maximum power available to allow the operator more subtleties in speed control and to prevent the operator from exceeding safe speeds (for example, peak speed limits) . The accelerator can be limited differently depending on whether the 902 board is in aerodynamic lift or not. For example, less power may be available when the jet hydrofoil 900 is in no aerodynamic lift mode (or travel mode), so the operator must use the proper technique to initiate aerodynamic lift (or aerodynamic lift mode) , thereby preserving battery usage and making the aerodynamic lift transition smoother for the operator. Power limitation can also be used to protect against overheating of supply system components.
[0092] [0092] If the throttle controller 906 is a wireless controller, throttle cable 908 can be eliminated as one of the components of the throttle system. A wireless accelerator controller can include a belt to connect it to the 902 board or the operator. The wireless throttle controller can also be coupled to the throttle cable 908 with the throttle cable 908 which serves dual functionality both as a string when its built-in wiring does not serve as a communication link as well as the communication link in certain situations. This would allow the operation of the 900 jet hydrofoil through wired communication even when the wireless functionality of the wireless accelerator controller stops working (for example, when the battery that powers the wireless accelerator controller has run out).
[0093] [0093] The 906 throttle controller may include a built-in display (in addition to or instead of a display mounted in a 902 board cavity). The display provided on the 906 throttle controller may be easier to read because it is closer to the driver. The 906 throttle controller can be used to advise the driver about speed, engine rpm, device health (eg battery power, component temperature), and / or effectiveness or driving directions using vibrations, lights, text, graphics, noise or any combination thereof. For example, the throttle controller 906 can vibrate to indicate that the battery power of the jet hydrofoil 900 is running low, or it can display a message through the display that indicates that the jet hydrofoil 900 is drawing too much current.
[0094] [0094] The accelerator can be limited to multiple predetermined settings, depending on the characteristics of the operator. For example, an operator can choose “beginner”, “intermediate” or “experienced” modes, depending on their particular skill level that would change the speed limits set when using the 906 throttle controller. levels can also gradually increase, so that all users of the 900 jet hydrofoil must start at the “beginner” level and that after a certain number of hours (for example, determined using the driving data), the operator can proceed to the next levels. The throttle may include a safety braking feature (for example, via throttle controller 906) to stop a thruster and / or collapse a folding thruster. If the throttle controller 906 is wireless, it can be used to determine the possibility that the operator has fallen (for example, after a wireless connection,
[0095] [0095] The 906 throttle controller can include at least one button or trigger. In some implementations, the 906 throttle controller only includes a button that can be moved upwards to increase speed, downwards to decrease speed. In other implementations, such an accelerator controller may also include functionality to move the left and right button to navigate the 900 jet hydrofoil (for example, by wing position shift, weight distribution, optional rudder rotation, and other features jet hydrofoil 900). In other implementations, the 906 throttle controller includes two buttons as a safety feature, both of which must be activated (for example, pressed by the driver) to allow the 900 jet hydrofoil to operate and move. The throttle can also have a reverse mode to actively allow braking by the driver who can slow the hydrofoil jet 900 without turning off the engine.
[0096] [0096] FIG. 10A illustrates an example of a jet hydrofoil 1000 controlled using a handlebar 1002 in a first position 1006, according to implementations of the present disclosure. The handlebar 1002 comprises a handlebar attached to a frame (for example, a rigid mast with a single anchor point or with multiple anchor points) that is attached to both the handlebar at one end and a top surface of a 1004 board jet hydrofoil 1000 on the other end. The handlebars 1002 can also incorporate an accelerator system (for example, the accelerator system of FIG. 9), integrating the accelerator controller (for example, the accelerator controller 906 of FIG. 9), and accelerator controller communication link on the handlebars, or providing a fastener for a wireless controller to be positioned or connected (for example, temporarily wired) while conducting the jet hydrofoil. An operator of the jet hydrofoil 1000 can engage the handlebar throttle system 1002 to control the jet hydrofoil 100.
[0097] [0097] Handlebars 1002 can be moved from the first position 1006 to a plurality of other positions for flexibility. FIG. 10B illustrates an example of jet hydrofoil 1000 controlled using handlebars 1002 in a second position 1008, in accordance with implementations of the present disclosure. The second position 1008 produces a smaller angle between the handlebars 1002 and the board 1004 compared to a greater angle produced by the first position 1006. The handlebars 1002 can have an adjustable height to be compatible with varying operator heights and can be attached to the board 1004 by means of a plurality of mechanisms which include, but are not limited to, a joint, a joint and a ball and socket connection. Additional components can be attached to the 1002 handlebars which include, but are not limited to, a display and a container which are each attached to the handlebars or frame.
[0098] [0098] The handlebars 1002 can provide additional stability for the operator and can make it easier for the operator to influence a direction of the board 1004 while operating the jet hydrofoil 1000. The handlebars can be mounted to the frame comprising a mast that is similar to masts used on scooters or comprising a flexible A frame. The components of the 1002 handlebars that include at least the handlebars and the frame can be removable (i.e., detachable and affixable). Both wired and wireless throttle controllers can be made to be removed from handlebars 1002 and the frame can be removed from board 1004. In some implementations, the frame has an A frame shape and uses an hourglass fit (for example, made of rubber) to join each frame A leg. The frame can include an emergency release on a mechanical joint or magnetic fixture with the 1004 board to allow the frame to bend and protect the 1000 jet hydrofoil and / or the operator in the event of an impact or accident. The frame can be connected to and integrated with a front area of the 1004 board. Additional electronic parts (eg speedometer) can be mounted on or near the handlebar of the 1002 handlebar accelerator.
[0099] [0099] FIG. 11 illustrates an example of a hydrofoil from an 1100 jet hydrofoil, according to implementations of the present disclosure. Hydrofoil 1100 is similar to hydrofoil 104 of FIG. 1 and is coupled to a board (for example, board 102 of FIG. 1) of the jet hydrofoil. Hydrofoil 1100 includes a rod 1102 and an outboard wing 1104 and a bow wing 1106 coupled by means of a plurality of wing connection screws 1108 to a propulsion module 1110. Hydrofoil 1100 may include fewer or more wings than the stern wings and the bow wings 1104-1106. The plurality of wing connection screws 1108 couple the stern wing 1104 and the bow wing 1106 to the propulsion module 1110 (for example, similar to the propulsion module 106 in FIG. 1) which is connected to the rod 1102. The tie rod 1102 can include at least one wire that can serve as a communication link between the accelerator system (not shown) that allows a conductor to control the jet hydrofoil and an engine (for example, an electric motor in a power system, such as the feeding system 112 of FIG. 1) that controls the jet hydrofoil using commands generated based on the driver settings received from the accelerator system.
[0100] [0100] In some implementations, a communication path between an accelerator system (operated by the driver) and a jet hydrofoil engine is wired and runs between the accelerator system accelerator controller, a junction box in a cavity of the board, an electronic unit in a cavity (for example, the same or a different cavity) of the board, the hydrofoil rod 1102 1100, and the power system motor in the propulsion module
[0101] [0101] A power system comprising an engine (for example, an electric motor), a motor controller, and at least one battery can be encapsulated in a positive-shaped subsea housing comprising the 1110 propulsion module that is integrated with hydrofoil 1100. The rod 1102 can travel approximately perpendicular to the jet hydrofoil board and can be integrated with the 1110 propulsion module. A top or end portion of the rod 1102 can fit into a rod slot (for example, the slit slot 402 of FIG. 4) of the board and the rod 1102 can be attached to the board with the use of screws or a similar mechanism. A tie slit location can be in a stern quarter (1/4) of the board. The rod 1102 can be made of carbon fiber with a foam core, with spacing to allow at least one wire to travel through a length of the rod 1102 that connects the power system on the 1110 propulsion module to electronic parts attached to the board and in communication with the throttle controller. The rod 1102 can end in the propulsion module 1110 and the propulsion module 1110 can compose a horizontal segment of hydrofoil 1100 between the stern and bow wings 1104-1106.
[0102] [0102] FIG. 12 illustrates an example of a hydrofoil of a jet hydrofoil 1200, according to implementations of the present disclosure. Hydrofoil 1200 is coupled to a board (for example, board 102 of FIG. 1) of the jet hydrofoil. Hydrofoil 1200 includes a rod 1202, a tray 1204 attached to one end of the rod 1202 and a propulsion module 1206 attached to the rod 1202. The rod 1202 can extend below the propulsion module 1206 and can be attached to a fuselage with wings (not shown) that helps direct and stabilize the jet hydrofoil. The rod 1202 can have a plurality of dimensions that include, but are not limited to, approximately 88.9 centimeters x 10.16 centimeters (35 inches x 4 inches). The rod 1202 can have a constant rope (for example, 11.93 centimeters x 1.52 centimeters (4.7 inches x 0.6 inches)). The rod 1202 can be tapered (for example, to be 12.44 centimeters (4.9 inches) long and one end that enters the board and 9.9 centimeters (3.9 inches) at an opposite end that joins the module propulsion system 1206). Tray 1204 can be attached to the board which is rigid or can be attached to the board which is inflatable by using a specialized adapter 1210 which is similar to adapter 708 of FIG. 7B.
[0103] [0103] Tray 1204 can accommodate a supply system (for example, a supply system comprising at least one motor, motor controller, battery, etc.) and the propulsion module 1206 can accommodate a set of gears 1208 and be coupled to a thruster with an optional protective thruster guard surrounding the thruster (e.g., thruster 108 and thruster shield 110 of FIG. 1). Such a jet hydrofoil can also use a cavity board to house the feed system, instead of a separate board mounted tray. The gear set 1208 may comprise an array of bevel gears. A first gear of gear set 1208 is connected to a motor stored in tray 1204 by means of a driving shaft 1210 (also called driving shaft) on rod 1202. A second gear of gear set 1208 is connected to the thruster via a propeller shaft 1212 in the propulsion module 1206 and is in contact with the first gear of gear set 1208. Since the engine runs (for example, in response to receiving information from the motor controller to increase speed), the the first gear is connected (for example, at a faster speed) by means of the driving shaft 1210 which results in the turning of the second gear, thereby turning the thruster through the propeller shaft 1212 to operate the jet hydrofoil.
[0104] [0104] Tray 1204 can include a hole (for example, a predetermined opening) that allows the conductor shaft 1210 to pass through the rod 1202 and through the hole for coupling with the motor housed in the tray 1204. The rod 1202 also allows that the driving shaft 1210 passes through an internal housing area of the rod 1202. The propulsion module 1206 can be integrated into the rod 1202 at a location above the wings (not shown) of hydrofoil 1200 instead of being adjacent to the wings as in hydrofoil 1100 of FIG. 11. Therefore, the propulsion module 1206 is integrated into the rod 1202 at a point closer to the board and a separate horizontal piece may comprise a fuselage (not shown) part of the hydrofoil 1200 to position the wings. The fuselage can run parallel to the board and be attached to the other end of the rod 1202 at approximately a right angle. In some implementations, the rod 1202 can be integrated with the fuselage as a component or the rod 1202 can fit into a slot in the fuselage and be removable.
[0105] [0105] In another implementation, a hydrofoil from a jet hydrofoil is attached to a board, in which the hydrofoil includes a tie rod and a propulsion module attached to the tie rod. The rod can extend below the propulsion module and can be attached to a winged fuselage that helps to direct and stabilize the jet hydrofoil. The rod can have a plurality of dimensions that include, but are not limited to, approximately 78.74 centimeters x 10.16 centimeters (31 inches x 4 inches). The rod can be directly attached to a rigid board with one or more cavities in it or the rod can be attached to a tray that is attached to the board which is rigid or the rod can be attached to the board which is inflatable by using an adapter specialist that is similar to adapter 708 of FIG. 7B. The propulsion module can contain an engine, a gearbox if one is used, and a propeller shaft. The propulsion module can also contain the engine controller, but the engine controller can be housed on the board instead. The batteries and the electronics unit can be housed in the board cavities or in the tray, if a tray is used.
[0106] [0106] The wings may comprise aft and front wings that are similar to the aft wings and bow wings 1104-1106 of FIG. 11. The wings of hydrofoil 1200 can be attached to the fuselage instead of the 1206 propulsion module. The wings can be attached as an integrated part or in a removable form. The wings can be made of carbon fiber and can be designed to be easily removable, replaceable and differently spaced (for example, using screws). The wings provide lift and stability during the operation of the jet hydrofoil. Wing removal may not only be used for repair and replacement purposes (that is, when a wing is damaged it is replaced), but it can also be used to allow a jet hydrofoil to be used by skill drivers and / or different profiles (for example, different wing types and combinations allow an advanced high conductor and a beginner low conductor to use the same jet hydrofoil). This allows a driver to use the same jet hydrofoil while increasing knowledge level by modifying the jet hydrofoil wings. The wings can have a variety of shapes that include curved edges that curve upward and / or downward (in addition to other curved orientations). The wings may include flaps that provide the curved edges.
[0107] [0107] The relative incidence angles of the jet hydrofoil wings and the distance between the stern wing 116 and the bow wing 118 affect whether or not the jet hydrofoil is set to “high performance” (i.e., an advanced or specialized driver) or for “low performance” (ie a beginner driver). For example, the higher aspect ratio wings spaced together will yield a higher performance result while the lower aspect ratio wings spaced further apart will yield a lower performance result. A superior performance result means that the jet hydrofoil board will be more maneuverable and faster, but the margin of error to maintain aerodynamic lift stability will be lower. An inferior performance result means that the jet hydrofoil board will be more tolerant of one conductor per / under correction for instability and thus easier to drive. The positioning of the wings will determine where the center of lift is positioned when the jet hydrofoil is in aerodynamic lift mode. The perceived wing location is a consideration when determining the location of the riser crack during the manufacture of jet hydrofoil. When an end user is moving the jet hydrofoil wings to adjust performance results, it may be desirable to position the bow wing close to the rod or to make other adjustments to position the wings so that the center of rise when the jet hydrofoil is in aerodynamic lift mode aligns with the float center when the jet hydrofoil is in travel mode.
[0108] [0108] A wave produced by a jet hydrofoil surface drilling rod (for example, rod 114 in FIG. 1, rod 1102 in FIG. 11, rod 1202 in FIG. 12) stacks along a rear side of the jet hydrofoil, which continues up and to the sides in the air, creating a spray. Spray drag is a significant portion of the overall tie drag, but can be used to the advantage of jet hydrofoil. In configurations where part of the feed system is not located under water in the jet hydrofoil propulsion module, the riser spray can reach an optional board heatsink located on a bottom board surface to provide cooling for anyone components of the jet hydrofoil supply system (eg engine controller, batteries). In addition, the supply system can be cooled using water coolant that is taken from the riser below the water surface and then pumped up through the riser and into the supply system.
[0109] [0109] A hydrofoil from a jet hydrofoil (for example, hydrofoil 104 from FIG. 1, hydrofoil 1100 from FIG. 11, hydrofoil 1200 from FIG. 12) can be detachable from the board (which is rigid or inflatable) so that multiple boards can be used with a hydrofoil (that is, the same hydrofoil). The hydrofoil can pivot to fold for storage or transportation. The hydrofoil may have movable control surfaces (for example, adjustable plate flaps attached to the hydrofoil wing areas) that can be adjusted to change the transverse shape of the aerodynamic lift surface for performance considerations (for example, stability). The movable control surfaces can be attached to the stern or the bow. The movable control surfaces can be attached to a rear end or a front end of the wings or different areas. The movable control surfaces (ie flaps) can rotate the entire wing or just predetermined portions of the wing. The movable control surfaces may include a pusher mechanism that activates the flap movement of the movable control surface. The movement of an adjustable plate flap (also called a control flap or flap) that makes up the stern part of a hydrofoil wing (that is, a stern control flap), for example, will change the cross shape of the wing. Such a movable control surface on the stern hydrofoil will adjust the finish / pitch of the jet hydrofoil. For example, if the flap on the stern wing of the jet hydrofoil can pivot so that the rear edge is pointing down, the jet hydrofoil nose will rise, and the jet hydrofoil will tilt up, higher than the surface. from water. If the flap on the stern wing of the jet hydrofoil can pivot so that the rear edge is pointing upwards, the jet hydrofoil nose will point below the water surface, and the jet hydrofoil will launch forward if such an angle tab is maintained. Such a stern control flap can be adjusted in a variety of ways that include, but are not limited to, an inertial measurement unit (IMU), a “driving height” sensor, a mechanical rod, or a similar mechanism.
[0110] [0110] An IMU can measure the angle of the board and adjust the flap to maintain a certain board angle, using a gyroscope or similar device. A “driving height” sensor (for example, an ultrasonic sensor) can measure the distance between the board and the water surface and adjust the flap to maintain a certain driving height above the water. A mechanical sensor (for example, a rear nose stick on the jet hydrofoil board) can measure waves on the water surface and adjust the flap directly using a cable or other mechanical device to make the jet hydrofoil react to the waves and keep a board stable. A movable control surface on the front hydrofoil (ie, a front control tab) will adjust the overall "driving height" of the jet hydrofoil so that the driving height will remain constant, but the jet hydrofoil will be driven higher or higher. further down the surface of the water, according to the position of the front control flap, which changes the amount of lift generated by the wing. Such a front control flap can be adjusted by the driver who moves a lever or other control mechanisms or by the driver which inserts a number that corresponds to a certain height above the water.
[0111] [0111] In some implementations, the aft and front wings (for example, the aft wings and bow wings 1104-1106 of FIG. 11) and additional hydrofoil wings can also be mobile control surfaces that are adjusted in addition to the movable control surfaces which comprise adjustable plate flaps. The mobile control surfaces can be attached to the propulsion module in addition to wings or can be attached to other areas of the hydrofoil that include, but are not limited to, the tie rod or the propulsion module itself. The mobile control surfaces can be intelligently driven by a computer (for example, using a machine learning mechanism that automatically adjusts the mobile control surfaces based on various conditions and associated data detected using sensors, as jet hydrofoil MEMS devices) that automatically compensates for speed and weight and the driver's ability to control (for example, adjust speed, direct and / or stabilize) the jet hydrofoil. The mobile control surfaces can also be manually operated / altered by the driver (for example, using an accelerator controller) based on various operator needs.
[0112] [0112] The jet hydrofoil can use an accelerometer, a gyroscope, an inertial measurement unit (IMU), or any other type of feedback loop control device (for example, other MEMS devices) to provide a feedback mechanism. self-stabilization that stabilizes driving by modulating battery power to stabilize the board during varying conditions (for example, when the driver requires assistance, or automatically as a response to waves). The stabilizing device can also be used to determine if the board has been overturned or hit a solid object that would trigger a response to stop the propeller and engine from operating and take the jet hydrofoil to an emergency stop.
[0113] [0113] FIG. 13 illustrates an example of a jet hydrofoil 1300 propulsion module, according to implementations of the present disclosure. The propulsion module 1300 is similar to the propulsion module 106 of FIG. 1. The 1300 propulsion module is coupled to a hydrofoil rod (for example, hydrofoil 1100 of FIG. 11) of the jet hydrofoil. The drive module 1300 includes a housing 1302, a tapered end 1304 coupled to the housing 1302 with the use of a tapered end seal 1306 and at least one screwing mechanism or similar mechanism (for example, threaded screw fastening) , and a heat sink 1308 coupled to housing 1302. Heat sink 1308 can be an optional component. When the 1300 propulsion module is made of aluminum, the 1300 propulsion module can act as a heat sink, which dissipates heat. When the 1300 propulsion module is made of other material (e.g. carbon), it may be desirable to include a heat sink panel made of aluminum or some other material with similar heat dissipation qualities. The tapered end seal ring 1306 may comprise an aluminum tapered end seal ring with at least one O-ring (for example, three silicone O-rings).
[0114] [0114] At least one camera may be incorporated at the tapered end 1304 to allow a conductor of the jet hydrofoil to make subsea records during the operation of the jet hydrofoil. At least one camera can have a variety of different types of camera types that include point of view cameras (POV) or 360 degree cameras with capabilities for magnification. At least one camera can be attached to the tapered end 1304 using a camera clip. The tapered end 1304 may have at least one opening to allow coupling of at least one camera using the camera holder. A camera window can be attached to the tapered end 1304 to protect at least one camera by serving as a scratch guard and providing a waterproof seal. At least one camera can be attached to other electronic components of the jet hydrofoil (for example, an electronic unit attached to a cavity in a jet hydrofoil board) via wiring that is also housed at the tapered end 1304 or via of wireless mechanisms.
[0115] [0115] Housing 1302 of propulsion module 1300 may also include an access panel to allow access to a supply system (e.g., supply system 112 of FIG. 1) which is housed in propulsion module 1300. A thruster system comprising a thruster and thruster shield (for example, thruster 108 and thruster shield 110 of FIG. 1) can also be coupled to thrust module 1300 at one end that is close to the supply system interior or other area of the 1300 propulsion module. A proximity between the propeller system and the supply system allows the supply system engine to more effectively control the propeller during the operation of the jet hydrofoil. The area of the 1300 propulsion module that houses the power system that includes an engine can be termed an engine housing area of the 1300 propulsion module which is differentiated from the 1302 housing which represents a main body area of the 1300 propulsion module.
[0116] [0116] A propulsion module (for example, propulsion module 106 of FIG. 1 or propulsion module 1300 of FIG. 13) is a hydrofoil component of a jet hydrofoil. The propulsion module is an underwater housing that can have a tight bulb shape and a hollow interior. The propulsion module is part of a hydrofoil structure and allows a propeller (coupled to the propulsion module) to attach itself to the hydrofoil structure in a hydrodynamic way. The propulsion module is designed to minimize drag and wet area while remaining large enough to house the necessary components that can include, but are not limited to, cameras, power systems and associated wiring. To minimize drag while retaining a shape that is simple to manufacture, a front section of the propulsion module can be elliptical in shape while a stern section can have a smooth bow.
[0117] [0117] The shape of the propulsion module can be determined by looking for a pressure distribution that gently increases without spikes as far as possible and then recovers smoothly. The pressure distribution can be determined using a pressure distribution curve that is used to determine the ideal drive module shape that is provided with the use of the optimized drive module shape. The shape of the chosen propulsion module can be varied based on a variety of factors that include, but are not limited to, driver information (eg weight and skill level) and jet hydrofoil performance requirements. FIG. 14 illustrates an example of an optimized 1400 propulsion module format, according to implementations of the present disclosure. The 1400 optimized drive module format is determined by graphical delivery using a pressure distribution curve 1402.
[0118] [0118] If the propulsion module has a more cylindrical shape with a tapered end and a tail end, this can cause a low pressure peak where the cylinder and the tapered ends come into contact. A shape that has a more continuous curve, like the one shown in FIG. 14, can produce less hydrodynamic drag, despite having a larger volume, due to creating such a low pressure spike. It may not be practical for manufacturing purposes to compose an optimized propulsion module format, due to the fact that creating such a curve can add more weight. For example, if the propulsion module is made of aluminum, made of a material with more heat insulation, or made of carbon materials and foam core, a simplified airfoil shape may be heavier or more difficult to manufacture than a cylindrical shape.
[0119] [0119] Consequently, the optimized drive module format 1400 can be more determined by the diameter and length of the module components (for example, the motor and potentially the gearbox and the motor controller). An array of propulsion module components can determine an ideal balance between simplified airfoil shape and maintained cylindrical shape. The positioning of the propulsion module towards the tie is also affected by hydrodynamic problems. Placing the propulsion module directly under the rod or in front of the rod, instead of at the stern of the rod, can make the jet hydrofoil easier to turn as it moves the propeller closer to the rod, and the rod acts as a pivot point of the jet hydrofoil. If the thruster is positioned too close to the rod, however, it can cause an unwanted pressure spike, effectively making such a design a larger drag source.
[0120] [0120] The entire jet hydrofoil feeding system can be housed in the propulsion module which contributes to conductor stability by consolidating the weight below the water surface, instead of adding more weight to the jet hydrofoil board. The components of the power supply housing (eg motor, motor controller, battery, etc.) adjacent to each other provide a more efficient system with less wiring between the various components. The propulsion module can be made of carbon fiber with a detachable tapered end (for example, the tapered end 1304 of FIG. 13) and rigid plate fastening points. In some implementations, the propulsion module includes small towers that allow the wings (for example, aft and front wings) to be mounted below the propulsion module and therefore, below the propeller. The propulsion module may include an access panel to facilitate the alteration of internally housed components. A heat sink (for example, heat sink 1308 of FIG. 13) can be coupled to the propulsion module which also provides access to the internal housing. When closed, the heat sink may be in direct contact with the motor controller to dissipate heat in the water and prevent the motor controller from overheating.
[0121] [0121] The detachable conical end provides a hydrodynamic shape and an access point for inserting and removing internal components of the propulsion module, such as the battery. The propulsion module can eliminate the need for the access panel using the access provided by the detachable conical end. The tapered end may have a built-in POV camera that is held in place behind a camera window using a camera clip. The tapered end includes a rotation detail that allows the tapered end to lock in different orientations for different camera placement. The propulsion module can have a plurality of dimensions that include, but are not limited to, approximately 86.36 centimeters x 15.24 centimeters x 10.16 centimeters (34 inches x 6 inches x 4 inches).
[0122] [0122] In some implementations, the propulsion module is attached to the hydrofoil rod above the wings, instead of acting as a fixation point for the wings. Mounting the thruster above the wings results in the thruster leaving the water before the wings if the conductor plates are too high. The propulsion module can also house fewer feeding system components to make it lighter and smaller with less wet area. For example, the propulsion module can house a cluster of gears (for example, gear set 1208 of FIG. 12) to translate the engine speed to the propeller speed that allows the electric motor and the battery and associated components are mounted to the board by means of a tray (for example, tray 1204 of FIG. 12), where a driving shaft (for example, driving shaft 1210 of FIG. 12) can extend from the motor through a passage on the tie rod for the gear assembly to drive the propeller by means of a propeller shaft (for example, the propeller shaft 1212 of FIG. 12).
[0123] [0123] Alternatively, in other implementations, the propulsion module that is attached to the hydrofoil rod above the wings, can accommodate part of the supply system (for example, engine, gearbox, etc.), instead of the whole feed and instead of the gear cluster. When using a smaller propulsion module to reduce the wet area and place the propeller above the hydrofoil wings, part of the feeding system can be housed on the board. While placing the heavier components (eg batteries) on the propulsion module can make the jet hydrofoil more stable to be driven, putting weight on the board also has advantages. For example, more weight on the board / less weight on the propulsion module can make the jet hydrofoil easier to turn. Adding more components to the board does not increase the board size, but adding components to the propulsion module can increase the propulsion module size. The propulsion module can be positioned so that the volume of its mass is in front of the tie, at the stern of the tie or directly in line with the tie. The positioning of the propulsion module facing the rod will affect the propeller's proximity to the rod and the weight distribution of the propulsion module, both of which will affect the driver's position. Instead of being coupled along the tie rod, the propulsion module can also join the hydrofoil at another point along a fuselage that includes, but is not limited to, above a stern wing of the jet hydrofoil.
[0124] [0124] The propulsion module may have an integrated air circulation bilge pump to cool the engine and / or the engine controller and remove any water that may have entered during operation. Linear water sensor strips can be attached along the entire propulsion module or tray that houses the feed system or other areas of the jet hydrofoil to detect water intrusion. The placement of linear water sensor strips can be close to joints and seals and along bottom surfaces of the propulsion module and / or the tray. If water is detected, a battery relay can open and trigger an error indication on a display (for example, display unit 604 in FIG. 6) that can turn off the jet hydrofoil. Water pressure sensors can also be coupled to the propulsion module to detect a thruster depth. Depth information can be used to detect a “driving height” of the jet hydrofoil board. Water pressure sensors can be used to modulate the power coming from the engine to prevent the hydrofoil from venting, thereby preventing the jet hydrofoil from spinning out of the water. The propulsion module can be pressurized by a pressurizing machine to check for leaks. Pressure sensors can be provided to measure the pressure produced and an intelligent system can be provided in the jet hydrofoil to advise the operator / driver regarding the possibility of the measured pressure retaining the jet hydrofoil in the water and the jet hydrofoil being thus safe to be placed in the water for operation.
[0125] [0125] In some implementations, a propulsion module that houses part of the supply system (for example, motor, gearbox, motor controller, etc.) can be made of a material, such as aluminum that dissipates heat, so that entire propulsion module acts as a heat sink, it cools the internal components as the jet hydrofoil passes through the water. Alternatively, the propulsion module can be made of carbon fiber or a similar material and have a heat sink panel, similar to the 1300 propulsion module of FIG. 13. The propulsion module may also include some components of the electronics unit that include, but are not limited to, a microcontroller (for example, a microcontroller used to monitor the propulsion module temperature). The propulsion module may be smaller in size and may have a variety of sizes that include, but are not limited to, a size of 34.29 centimeters (13.5 inches) in length and 6.35 centimeters (2.5 inches) in diameter. The size and shape can be determined by the interior components (for example, motor diameter, whether or not the motor controller or microcontroller is included), but can also be determined by hydrodynamic problems, such as pressure distribution.
[0126] [0126] In addition, the propulsion module can use a threaded mechanism to allow both the tapered end and the motor housing to be screwed and unscrewed from the central unit or the main body of the propulsion module. The propulsion module can use O-rings (for example, silicone O-rings) to make sealed tight connections. This can improve the ease of service and assembly of the propulsion module by providing easier access to propulsion module components and making it easier to assemble parts
[0127] [0127] FIG. 15A illustrates an example of a jet hydrofoil feeding system 1500, according to implementations of the present disclosure. The feed system 1500 can be housed in a hydrofoil propulsion module of the jet hydrofoil (for example, similar to the feed system 112 in FIG. 1) or the feed system 1500 can be housed in a tray attached to a the hydrofoil rod of the jet hydrofoil (for example, similar to the feeding system in tray 1204 of FIG. 12) or the feeding system 1500 can be housed in a hollow of the board. The power system 1500 includes an access panel 1502, a heat sink 1504 attached to the access panel 1502, a motor controller 1506 attached to the heat sink 1504, a motor system 1508 attached to the motor controller 1506, and a drive shaft. propeller 1510 coupled to engine system 1508. In some implementations, power system 1500 does not include access panel 1502 and / or heat sink 1504 and in other implementations, heat sink 1504, motor controller 1506, and a The battery can be housed elsewhere (for example, on the board) of the 1508 engine system and a propeller shaft (for example, on the propulsion module). The engine system 1508 may comprise a motor coupled and powered by a battery, and a gearbox coupled to the motor to increase the torque of the motor. The engine system 1508 controls a thruster (for example, thruster 108 of FIG. 1) through thruster shaft 1510. The engine of the engine system 1508 can comprise any of an electric motor, a gas powered engine, a motor powered by sunlight, other types of motors, and any combination thereof.
[0128] [0128] Motor controller 1506 can be located inside the propulsion module, aft of the motor of the motor system 1508, in contact with the heat sink 1504, and adjacent to the battery. Motor controller 1506 can also be located inside the propulsion module, aft of the motor of the 1508 motor system, which is made of aluminum or a similar material, so the entire module acts as a heat sink. The 1506 motor controller can also be located inside the board, in the second cavity or in the adapter tray, adjacent to a heat sink. The 1500 power system may also include one or more sensors that include, but are not limited to, digital temperature sensors that can be coupled to the engine, 1506 engine controller, battery or batteries, and other 1500 power system components to measure various temperatures and to determine the possibility that the components are working properly. The temperatures that the digital temperature sensors detect can be shown on a display (for example, display 604 in FIG. 6) on the jet hydrofoil or on a display on the accelerator and can appear on test records (for example, tests that are part of the driving data). Digital temperature sensors can also be used to trigger warning signals or a device shutdown of the jet hydrofoil or various components of the jet hydrofoil (for example, electronic parts) for driver safety.
[0129] [0129] The propeller shaft 1510 can exit the engine system 1508 and can accept a propeller from the propeller system. The 1510 propeller shaft is supported by bearings that have the capacity to take thrust and other loads that the propeller can generate. The propeller shaft 1510 can also take loads generated by a driving shaft (for example, the driving shaft 1210 of FIG. 12). Propellers of different sizes and shapes can be attached to the 1510 propeller shaft.
[0130] [0130] FIG. 15B illustrates an example of the engine system 1508 of the jet hydrofoil feed system 1500, according to implementations of the present disclosure. The engine system 1508 includes an engine 1512, a gearbox 1514 attached to the engine, and the propeller shaft 1510 attached to the gearbox
[0131] [0131] The 1508 engine system can be activated or controlled by receiving instructions from the 1506 engine controller to control the thruster system propeller. For example, when a jet hydrofoil operator presses an accelerator controller, information (for example, increasing the speed of the jet hydrofoil) is generated and processed in a command (for example, processed by an electronic unit attached to a board of the jet hydrofoil) which is then transmitted to the engine controller 1506. Once the command is received by the engine controller 1506, the engine controller 1506 controls the operation of the engine 1512, thereby turning on the operation of the propellant system. If the command received by engine controller 1506 comprises increasing jet hydrofoil speed, engine 1512 will adjust to accelerate the propeller turn, thereby allowing the jet hydrofoil to be faster.
[0132] [0132] The 1508 engine system may also include a battery system comprising one or more batteries to power the 1512 engine. The battery system may include a slip battery that is coupled to a battery sled for easy sliding on the propulsion module and for connection to both engine controller 1506 and engine 1512. The battery sled allows a user to easily remove the battery to charge and reinsert the battery without having to directly reconnect battery wires to the engine controller 1506 and / or the 1512 engine. The battery sled can be made of carbon fiber, can include control wires, and can have a self-locating connector integrated into its stern end. The auto-location connector can be shaped like a cone that helps guide the auto-location connector in place as the battery sled is inserted into the propulsion module. Once the battery sled is inserted into the propulsion module, the integrated self-locating connector connects the battery (and / or control wires) to the motor controller 1506 and / or 1512 motor circuit.
[0133] [0133] The battery sled can be loaded with vertical batteries when the jet hydrofoil is on its side. This orientation facilitates a battery change performed by a single person and / or a battery change performed on a mobile surface such as a boat dock due to the jet hydrofoil being stably positioned on its side without any specialized equipment. FIG. 15C illustrates an example of a battery system 1550 from the engine system 1508, according to implementations of the present disclosure. The battery system 1550 includes a battery sled 1552, a battery 1554 attached to the battery sled 1552 and a self-locating connector 1556 attached to one end of the battery sled 1552. The self-locating connector 1556 connects the battery 1554 to the supply system circuit 1500. More than one battery can be attached to the battery sled 1552.
[0134] [0134] In some implementations, and referring to FIGS. 15A-15C, motor controller 1506 can be a 160 A motor controller, motor 1512 can be a 500 KV motor running at 58 V, gearbox 1514 can be a 4: 1 gearbox or an 8: 1 gearbox, the 1554 battery from the 1550 battery system can comprise two lithium polymer batteries (LiPo) connected in series using the 8 or 10 or 12 meter battery wire. Power 1500 comprises engine system 1508 and battery system 1550 and can be housed in a hydrofoil tray or a board cavity instead of being housed in the propulsion module. The 1550 battery system may include other types of batteries that include, but are not limited to, lithium iron phosphate (LiFePO4) or lithium ion (LiIon) batteries or any combination thereof.
[0135] [0135] In some implementations, instead of removing the battery sled (for example, the battery sled 1552 of FIG. 15C) to allow the charging of one or more batteries (for example, the battery 1554 of FIG. 15C) , one or more batteries can be locked in any of the propulsion module, the board and the hydrofoil tray (also called the plate tray). The user can then connect the hydrofoil to the entire jet in a charging device for charging one or more batteries. This configuration provides a safety advantage as the user does not have to handle the batteries, but adds complexity to the charging process as the entire jet hydrofoil needs to be transported for charging. This setting also prevents an operator / driver from conducting long driving sessions or changing drivers, which may require battery changes in the middle of the session while on the water. In other implementations, the battery system is housed above water (for example, in a jet hydrofoil board cavity or in a jet hydrofoil plate tray) and is connected via battery wires through the tie rod and for the 1508 engine system. This will allow you to easily change and charge one or more batteries. An auxiliary battery in addition to one or more batteries in the battery system can be provided in the jet hydrofoil (for example, on the board) to serve as a spare battery when one or more batteries in the battery system need to be changed or replaced.
[0136] [0136] The one or more batteries in the battery system can be housed in the propulsion module so that they are more contained compared to housing the one or more batteries in the battery sled while still providing the removal of one or more batteries from hydrofoil.
[0137] [0137] A soil fault detector can also be implanted in the jet hydrofoil to check the continuity between the battery's lead battery and a hydrofoil carbon body. There should be no continuity that results in a current flow that potentially travels through the water and to the conductor. Therefore, if continuity is detected, the battery relay can once again be opened and an error message can be generated on the display that may persist until the continuity problem is resolved with verification (for example, the solo checks for no continuity) or manually released by the user. In addition, an electric current sensor can be used to measure the power consumption of the jet hydrofoil and stop the engine (for example, the 1512 engine in FIG. 15B) if a rotor is locked or damaged. The electric current sensor can be used to detect when the engine tries to spin in open air that could produce a low current and a high speed (instead of spinning in the water, as desired), thereby stopping or limiting the engine. Low current and high speed levels can be determined using predetermined limits.
[0138] [0138] FIG. 16 illustrates a jet hydrofoil propeller system 1600 in accordance with implementations of the present disclosure. The thruster system 1600 includes a thruster 1602 that comprises two or more thrust blades 1604 and a thrust guard 1606 that surrounds thruster 1602. Thruster 1602 can have a variety of dimensions that include, but are not limited to, the diameter of 10 , 16 to 40.64 centimeters (4 to 16 inches). The thruster system 1600 can be coupled to a propulsion module (for example, propulsion module 106 of FIG. 1 or propulsion module 1300 of FIG. 13) which is in turn coupled to a tie rod of a hydrofoil or hydrofoil rod (for example, hydrofoil rod 114 of FIG. 1 or hydrofoil rod 1102 of FIG. 11) of the jet hydrofoil. The propeller 1602 and the propeller guard 1606 can be separately attached to the propulsion module or the impeller guard 1606 can be attached to the propeller 1602 which is attached to the propulsion module by means of a clamping mechanism. The 1606 propeller guard can also be integrated into the propulsion module or hydrofoil wings.
[0139] [0139] The two or more propeller blades 1604 are attached to the propulsion module by means of a propeller shaft (for example, the propeller shaft 1510 of FIG. 15A). Propeller 1602 can be mounted at the front or aft of the propulsion module and at the front or aft of the hydrofoil rod. The 1602 thruster can be optimized for predetermined node travel performance (for example, 27.78 km / h (15 knots)) with a predetermined input power (for example, 3725 watts or approximately 5 horsepower) in a predetermined throttle rpm (for example, 4000 rpm thruster). In some implementations, the jet hydrofoil may include a channeled thruster with a shape that adjusts a pitch distribution of the channeled thruster instead of the 1600 thruster system. The channeled thruster includes a thruster that is fitted with a water intake nozzle that it does not rotate and increases the effectiveness of the propellant. The channeled thruster can be positioned above or below a fuselage and hydrofoil wings.
[0140] [0140] Propeller guard 1606 can act as a safety feature. The propeller guard 1606 can be screwed to a top and bottom surface (or just one surface) of the propulsion module, which extends beyond the engine housing and protects the two or more propeller blades 1604. The propeller guard The propellant can function as a duct to supply the channeled propellant and is tuned to the 1600 propellant system to increase the efficiency and operation of the jet hydrofoil. The 1606 thruster guard can enhance the effectiveness of the 1600 thruster system at low speeds (for example, below approximately 18.52 km / h (10 knots)). The 1606 thruster guard can have a varied section to provide lift / stability and can function as an outboard hydrofoil wing. The 1606 thruster guard can have a variety of dimensions that include, but are not limited to, a diameter of approximately 20.3 centimeters (8 inches).
[0141] [0141] The jet hydrofoil can rotate the propeller 1602 in different directions, depending on the driver's style (for example, one style for “amateur” and another for “regular” driving styles). In the absence of other forces, a jet hydrofoil board will roll in the opposite direction from the direction in which the propeller 1602 is rotating, and the operator / driver must react to that force by pushing down the driver's weight to stabilize the board. Since the driver accelerates or operates the jet hydrofoil to be faster, the driver must push further down to balance these forces. It is ideal for driver comfort to allow the driver to push with the toes instead of the heels, so that the toes (instead of the heels) can be positioned close to an edge of the board via of a standing strap mechanism or other strap mechanism.
[0142] [0142] When rotating the 1602 thruster in one direction, the jet hydrofoil will be easier to be driven by a particular driver style and more difficult to be driven by the opposite driver style. The larger the propeller 1602 and the greater the torque applied by an engine (for example, the 1512 engine in FIG. 15B) of the jet hydrofoil, the greater the effect of the rotating direction of the propeller 1602 on the driver's ease of use. The jet hydrofoil may include an option to change the direction of rotation of the 1602 propellant to enable drivers of different styles (for example, “amateur”, “regular”, etc.) to use the same jet hydrofoil with a comfortable posture . The option can be controlled via an accelerator controller engaged by the driver (for example, changing a definition from one style to another when starting the jet hydrofoil) and which is communicating with an engine controller (for example, the motor controller 1506 of FIG. 15A) by means of an electronic unit (for example, electronic unit 602 of FIG. 6). Based on the information or commands received, the motor controller can change the direction of rotation of the 1602 thruster by changing the direction of the torque applied by the motor coupled to the motor controller. In some implementations, the jet hydrofoil may include two thrusters that are mounted in line and rotate counterclockwise and clockwise, respectively, to eliminate rotational torque and to stabilize a jet hydrofoil board by accelerating and decelerating it. if each of the two thrusters.
[0143] [0143] FIG. 17 illustrates an example 1700 of propeller turn directions compatible with driver posture during the operation of a jet hydrofoil according to implementations of the present disclosure. Propeller swing directions can be changed by changing a direction of propeller rotation (for example, propeller 108 of FIG. 1 or propeller 1602 of FIG. 16). Changing the propeller swing directions to match the driver's style improves the driver's posture and facilitates driving. Example 1700 includes a first match 1702, a second match 1704, and a third match 1706 that each highlight different configurations between the direction of propeller rotation and the driver's posture. In the first 1702 match, a driver with a “regular” posture is correctly matched to a “regular” propeller swing direction to provide ease of use. The propeller swing direction of the first 1702 match creates a force in a direction that is counterbalanced by a weighted force from the “regular” driver posture that positions the driver's feet toward an edge of a jet hydrofoil board .
[0144] [0144] In the second 1704 match, a driver with an “amateur” posture is incorrectly matched with a “regular” propeller swing direction that can cause problems during jet hydrofoil operation. The driving direction of propulsion of the second match 1704 creates a force in the same direction, as mentioned above for the first match 1702, but this force is not counterbalanced by a force weighted from the “amateur” driver posture that positions the feet of the driver towards a center of the board. Therefore, the propeller's direction of rotation and the driver's posture must be made compatible according to the third compatibilization 1706 which inverts a direction of rotation of the propeller to counterbalance the weighted force from the “amateur” driver's position that positions the feet of the conductor towards an opposite edge of the board. Additional propeller swing directions can be used by the jet hydrofoil to counterbalance different driver styles that are not categorized as "regular" or "amateur".
[0145] [0145] FIG. 18 illustrates an example of the foldable propeller blades 1800 of a jet hydrofoil propeller system according to implementations of the present disclosure. 1800 folding propeller blades can be used to improve safety and reduce drag, thereby extending battery life. The folding propeller blades 1800 are coupled to a propeller shaft that is coupled to an engine that is coupled to a propulsion module (for example, propulsion module 106 in FIG. 1 or propulsion module 1302 in FIG. 13 ) which is coupled to a hydrofoil (for example, hydrofoil 104 of FIG. 1) of the jet hydrofoil. The folding propeller blades 1800 comprise two or more propeller blades (for example, the two or more propeller blades 1604 of FIG. 16). Folding propeller blades 1800 can be oriented in a first folded position 1802 and in a second folded position 1804. Foldable propeller blades 1800 can be oriented in additional positions not shown (for example, positions between unfolded and folded, etc.) . The folding propeller blades 1800 change between the first folded position 1802 and the second folded position 1804, but the entire propeller system can also be changed.
[0146] [0146] As the folding propeller blades 1800 change from the first folded position 1802 (also called employed position) to the second folded position 1804 (also called folded position) or vice versa, a stop or lock mechanism (for example, blocks ) can be used to lock the 1800 folding propeller blades in place. In addition, the folding propeller blades 1800 can be coupled to the propulsion module with the use of a pin to allow rotation of the folding propeller blades 1800 between positions.
[0147] [0147] When the throttle is activated or engaged (for example, by means of a driver-operated throttle controller), the 1800 folding propeller blades begin to rotate and a first spin force or centrifugal force overcomes a second force or force of water in the folding propeller blades 1800, thereby allowing the folding propeller blades 1800 to be employed in the first unfolded position 1802. A first block is provided to prevent the folding propeller blades 1800 from opening more than the predetermined (for example, example, to prevent damage) and the centrifugal force locks the folding propeller blades 1800 in place in the first unfolded position 1802. When the throttle is released, the water force exceeds the centrifugal force, and the folding propeller blades 1800 stop rotating , which results in the folding propeller blades 1800 which move to the second folded position 1804 and which are stopped again by another or second block. Each blade of the 1800 folding propeller blades can rotate around a pin in an angled slot that guides the blades to a smoothing position as they fold into the second 1804 folded position.
[0148] [0148] The 1800 folding propeller blades can be used as a safety feature to stop the 1800 folding propeller blades from turning and then folding them to the second folded position 1804 when the throttle is not activated or engaged, which removes the danger for nearby drivers and bathers. A folding thruster system in a folded position on the dock also improves safety and prevents the thruster system from being damaged (for example, when there is no thruster guard). A folding thruster system can be used in wave driving where the driver may only occasionally want power assistance to reach the next one. When not in use, the 1800 folding propeller blades can fold in the second folded position 1804 or similar folded positions to reduce drag and conserve battery.
[0149] [0149] The displacement of the various positions of the folding propellant can be manually performed by the driver (for example, by selecting an option on the display of the electronics unit on the board or on the display on the accelerator controller) based on operating requirements or can be automatically performed by the jet hydrofoil with the use of sensors and feedback mechanisms (for example, machine learning mechanisms) and based on varying conditions. Therefore, the 1800 folding propeller blades can represent mobile control surfaces (in addition to the adjustable flaps on the hydrofoil wings) of the jet hydrofoil that can automatically control the jet hydrofoil.
[0150] [0150] FIG. 19 illustrates an example of a hydrofoil 1900 from a jet hydrofoil that includes the mobile control surface 1902, according to implementations of the present disclosure. The hydrofoil 1900 comprises a tie 1904, a propulsion module 1906 attached to tie 1904, a fuselage 1908 attached to tie 1904, a stern wing 1910 attached to fuselage 1908, a bow wing 1912 attached to fuselage 1908 and a propeller attached 1914 to the propulsion module
[0151] [0151] A jet hydrofoil according to the present disclosure can be packaged using a packaging material that includes, but is not limited to, a flexible piece of foam that is durable and waterproof (for example , expanded polypropylene) to securely pack the unusual shape of the jet hydrofoil. A foam C-shaped tube can be cut to length and wrapped around the hydrofoil, propulsion module and board components of the jet hydrofoil. Two pieces can be placed opposite each other to protect a circular shape, such as the propulsion module, and can also be interchanged to provide easy storage of packaging material
[0152] [0152] A jet hydrofoil (for example, jet hydrofoil 100 of FIG. 1 or jet hydrofoil 900 of FIG. 9), according to the present disclosure, can be operated using a variety of procedures or processes. In some implementations, a user (ie operator / driver) of the jet hydrofoil can obtain the jet hydrofoil ready for operation by first loading the batteries in a battery sled and defining a camera (for example, a POV camera) ) in a jet hydrofoil propulsion module. Although the jet hydrofoil is on its side, with a jet hydrofoil hydrofoil and a jet hydrofoil board that touches the floor or the boat dock, the user can insert the battery sled into the propulsion module using a opening (for example, a front opening). When pushed firmly or correctly in the propulsion module, the battery sled can indicate its engagement with electronic parts of aerodynamic lift making a series of sounds or flashing lights. These steps are performed in a dry area.
[0153] [0153] The user can insert the camera in one conical end of the propulsion module if desired, by pulling a camera holder in the opposite direction of a camera window in the conical end and fitting the camera in place behind the camera. The user can reattach and lock the tapered end to the propulsion module and can place the jet hydrofoil in the water with the hydrofoil entering first. The water must be deep enough to avoid contact between the hydrofoil and any surface, such as rocks. The user can affix one end of a safety strap to his body (by means of his ankle) and can affix the other end including a magnet to the hydrofoil to the jet failure / emergency switch location.
[0154] [0154] The user can place his feet on the foot straps (for example, a support foot on a back strap and a front foot with a front strap or just one foot, like the support foot on a single strap, like the rear strip). The user can stabilize on the board and push an accelerator controller from an accelerator system smoothly to move from a launch pad (for example, a boat, a pier). The user can accelerate by engaging the accelerator controller. Once a forward speed of approximately 14,816-18,52 km / h (8-10 knots) is achieved, a user can lift the front foot and begin the transition from non-aerodynamic lift to aerodynamic lift mode. The user can shift weight forward as needed during the transition to aerodynamic lift mode. The user can adjust the speed by engaging or releasing the throttle controller. To stop, the user can completely release the throttle controller that transits the jet hydrofoil back to non-aerodynamic or displacement mode. The user completely releases the throttle controller and can slide back to the launch pad when the jet hydrofoil is finished operating or driving.
[0155] [0155] In some implementations, when an accelerator with an inverse feature is used, the user can stop more quickly or precisely by using the inverse feature to brake instead of sliding to a stop. When an inflatable board is used instead of a rigid board, the user can inflate the board before driving and can attach the inflatable board to the hydrofoil feeding system (for example, the hydrofoil feeding system 704 in FIG. 7A) with the use of board adapters for aerodynamic lifting. When the jet hydrofoil is configured with an intelligent accelerator, the intelligent accelerator limits power while the board is in contact with the water. After the user moves the weight as necessary to initiate the aerodynamic lift (that is, post-transition from the non-aerodynamic lift mode to the aerodynamic lift mode), the aerodynamic lift can begin and a sensor can recognize the board as aerodynamic lift. way, releasing the previous power limit set by the smart accelerator. When a jet hydrofoil with a removable propulsion module is used, the user can remove and charge the entire propulsion module instead of removing only the propulsion module's own batteries.
[0156] [0156] In some implementations, when a folding thruster is used, the user can use the accelerator to accelerate to catch a wave that can cause the folding thruster to be used / deployed. When the user navigates a wave or ripple, using the power of the wave to propel forward, no engine assistance is required, so the user can release the accelerator while surfing to smooth or retract the folding thruster to reduce the drag. In wave navigation mode, the folding thruster does not need to rotate. When the user engages the throttle again for power assistance, the folding thruster can be employed. In an open ocean, this method of using jet hydrofoil can allow the driver to cover a long distance while using less battery due to the fact that the driver catches larger undulating waves. To stop, the user can release the accelerator and can transition back to the mode without aerodynamic lift or travel. When the user releases the throttle completely, the folding propellant can fold and the board will slide to a stop.
[0157] [0157] A method and system, in accordance with the present disclosure, provides a vessel device with a hydrofoil and electrically powered propellant. The vessel device comprises a board, an accelerator attached to a top surface of the board or wirelessly attached to the board, a hydrofoil attached to a bottom surface of the board, and an electric propeller system attached to the hydrofoil, where the electric propulsion system powers the vessel device using information generated from the accelerator. In an implementation, the accelerator may comprise an anchor point attached to the top surface of the board, a cable attached to the anchor point, and an accelerator controller attached to the cable, where information is generated when an operator of the vessel device engage the throttle controller. In another implementation, the accelerator may comprise a handlebar coupled to the top surface of the board, where the handlebar is adjustable for a plurality of positions, and a controlled accelerator attached to the handlebar, in which information is generated when an operator of the steering device vessel engage the throttle controller, in which the operator additionally holds the handlebars for stability during operation. In another implementation, the accelerator may comprise a portable, wireless controller, which can also be attached to the operator, attached to an accelerator cable, or attached to the handlebars.
[0158] [0158] The hydrofoil may comprise a rod attached to the bottom surface of the board, a propulsion module attached to the rod, and at least two wings attached to the propulsion module. In some implementations, the hydrofoil includes only one wing. When the hydrofoil comprises at least two wings, the at least two wings rise when the vessel device is powered by the electric propeller system. The at least two wings can be coupled to a bottom surface of the propulsion module so that the propulsion module is above the at least two wings of the hydrofoil (that is, the at least two wings are not integrated into or with the module propulsion). The at least two wings can also be coupled to other areas of the propulsion module which include, but are not limited to, an intermediate section between the bottom surface and a top surface of the propulsion module.
[0159] [0159] The hydrofoil may additionally comprise a rudder coupled to any of the tie rod and the propulsion module (or another area of the jet hydrofoil) and at least one adjustable flap coupled to the stern or bow hydrofoil wings (or other area jet hydrofoil), which can be mobile control structures that provide system stability for jet hydrofoil. The mobile stability system automatically stabilizes the vessel device using any of the operating speed, ambient conditions, height and pitch of the jet hydrofoil and operator associated data. The feedback loop fed by the height and pitch of the jet hydrofoil can include a plurality of sensors (eg, IMU) and a plurality of algorithms (eg, control system algorithms). The plurality of sensors can analyze the control of the jet hydrofoil and send data associated with the electronic unit that processes the data using the plurality of algorithms that result in adjustments in the mobile control structures to stabilize the jet hydrofoil.
[0160] [0160] For example, the feedback mechanism can detect that the jet hydrofoil is too low and can automatically adjust the mobile control structures to raise the jet hydrofoil. The gain or responsiveness of the control system can also be adjusted by the operator (for example, set using a display or phone connection to the jet hydrofoil). The jet hydrofoil can include additional mechanisms (such as machine learning algorithms) that optimize the conducting of the jet hydrofoil based on various conditions detected using the jet hydrofoil sensors). The level of assistance required by the control system can be based on the operator's age, height, weight, posture, driving style, driving history and skill level. The propulsion module may comprise a tapered end that includes at least one camera, a body housing attached to the tapered end, and a heat sink attached to the body housing. The at least two wings may comprise a stern wing coupled to a stern area of the hydrofoil propulsion or fuselage module, and a bow wing attached to a front area of the fuselage propulsion or hydrofoil module, wherein the bow wing it is larger than the stern wing. When the hydrofoil includes only one wing, the wing may be the stern wing, the bow wing, or a different type of wing located in a different location.
[0161] [0161] The electric propeller system may comprise a power system that includes an electric motor, a battery that powers the electric motor, and a propeller shaft driven by the electric motor, in which the power system is housed in the body housing of the propulsion module, and a propeller coupled to the supply system by means of the propeller shaft, in which the supply system controls the propeller by means of the propeller shaft using the information generated by the throttle controller. The electric thruster system may additionally comprise a thruster protector coupled to the conical end of the propulsion module, where the thruster protector is positioned around the thruster.
[0162] [0162] The thruster can be a foldable thruster (or folding thruster) with a plurality of blades, in which the foldable thruster additionally folds when the throttle controller is not engaged by the operator and the plurality of blades stop rotating. The vessel device may additionally comprise an electronic unit housed in a first or second cavity of the board, where the electronic unit receives the information from the accelerator controller and processes the information to provide at least one command. The at least one command can be transmitted by the electronics unit to a motor controller of the supply system to control the motor, which controls the propeller shaft, which controls the propeller.
[0163] [0163] The electronics unit may comprise a first microcontroller that receives the information from the throttle controller, processes the information to provide at least one command, and transmits the at least one command to the supply system motor controller, and a second microcontroller that records additional information associated with the operation of the vessel device. The electronics unit may additionally comprise a display and an emergency switch, in which the switch is connected to the operator by means of at least a foot strap or cord or strap to disconnect the vessel device when the operator disengages himself from the vessel device . The electronic unit receives the information from the throttle controller using any of the wired and wireless connections.
[0164] [0164] A float center in a non-aerodynamic lift (or offset) mode and a lift center in an aerodynamic lift mode are aligned. The non-aerodynamic lift mode is when the board is in contact with a body of water during takeoff from the vessel device and the aerodynamic lift mode is when the board is above a surface of the body of water during operation of the vessel device . The center of buoyancy in non-aerodynamic lift mode and the center of lift in aerodynamic lift mode are aligned by aligning a center of an upward force generated by a board float when the jet hydrofoil is in non-aerodynamic lift mode with a center of an upward force from a rise generated by at least two wings when the jet hydrofoil is in aerodynamic lift mode. Alignment may include shaping the board with a predetermined design that provides a center of buoyancy near or near or approximately close to a specific area or position of the board (i.e., a board position) and positioning the hydrofoil that includes the hairs minus two wings below the board close to the board position. The at least one foot strap that is coupled to the top surface of the board can also be positioned relative to the board position provided by the predetermined design of the board.
