    Propulsion in ships through the reaction system. Reaction propulsion system in boats by the advance admission of water in the bow for the push of a boat to move through the water. The thrust of a boat, for its displacement by water, is produced by introducing a conduit or conduits that connect the front, more forward bow and aft rear, placing the propeller, turbine or propellant pump in its interior so that in the prow a suction of the water takes place and in the stern a impulsion that causes the movement of the ship by the force resulting from the difference of pressures that generate the propellers in front and behind the boat. The governability of the ship will be made by varying the revolutions of the propellers in the case of more than one conduit along with the placement of rudder systems. The exceptionality of the invention is at the point where the suction is made in the bow bulb. (Machine-translation by Google Translate, not legally binding)

    Jet propulsion system on ships by admissionadvanced water in the bow for the thrust of a boatfor its movement through the water
    Technical Sector
    The invention is in the technical sector of shipbuilding, specifically in the way in which the thrust of the ship is produced for its movement through the water.
    State of the Art
    At the moment the propulsion of the boats by means of propellers is produced by the difference of pressures that are generated in front of and behind the same when turning on its axis due to the shape of its blades. This pressure difference causes a force that allows the water to move laterally on its bow so that the ship can pass through it, which means navigation.
    Currently the bow bulb is placed inside the water to break it and move it to the sides like a needle tip.
    Although there are propulsion systems that we could call a reaction, where the water is suctioned to take it to the stern where it produces a thrust, the novelty of this system is in the place where the suction is placed, at the most
    in advance, where the water breaks and the bow bulb is placed.
    Object of the invention: technical problem - proposed solution
    The object of the invention is the jet propulsion system in ships by early admission of water into the bow for the thrust of a vessel for its movement through the water. It consists of the way in which the different pressures are placed in the water so that its difference produces the force that causes its displacement and especially where the suction is carried out in the front.
    The proposed solution is to transfer the depression that occurs in front of the propeller to the front of the bow through a conduit that joins that point of the bow and the rear stern, placing the propeller inside. In the bow there is a suction that pulls the boat forward with less water displacement to the sides, while in the stern the positive pressure pushes the ship by difference with the negative suction pressure that occurs in the front forward.
    The bow bulb now changes its function, instead of pushing the water towards the sides it absorbs it to send it to the stern by the impulse of the propeller that is placed inside the duct.
    The advantages of this new way of placing the pressures around the boat and around the propeller is a decrease in the positive pressures ahead, which results in greater efficiency in the thrust mechanism for displacement and consequently fuel savings .
    The execution of this system is carried out by means of the introduction of a conduit that will be filled with water inside the hull and that in the design of the section of the ship must be thought to resituate its center of gravity.
    The system is similar to that used by jet airplanes, but in a much denser fluid such as water and mainly due to the placement of the liquid intake at the tip, where a suction is produced that pulls the ship at the same time that is opening the way to it.
    The propeller that transmits the force of the motor to the liquid to produce its movement and pressure can be by means of the traditional propeller system, by means of a turbine, pump or any other mechanical element that causes pressure differences before and after the passage of water.
    Description of the drawings.
    The bow bulb (1) that traditionally had its rounded tip, now becomes a hole through which water enters a conduit (2) in which the propeller is rotating and which sucks the water in front of the ship ( 3) in its bow and drives it to its rear aft (4).
    The duct can be unique, straight from bow to stern, with a single propeller and the government being performed by rudders (Figure 5).
    But there are also variations such as bifurcations in two ducts (6), each with a propeller, as if it were the legs of a pair of pants. Here the turns at different revolutions of the propellers on one side or on the other side will produce greater thrust on one side of the ship than on the other which will produce a turn in its trajectory.
    There may also be variations consisting of two straight bows from bow to stern with their respective inner propellers (Figures 8 and 9).
    In these last two cases, governance will be produced by the difference in revolutions of the propellers, together with the help of rudders that can be incorporated. And in the latter case, it can cause a turn on itself of the ship by rotating the propellers in the opposite direction.
    The tip of the front bulb, now suction, will have a grid (8) calculated so that the effective section of the duct is not affected, to prevent entry into the tube of elements that could damage the propellers or turbines and the system in as a whole
    When the system is of a tube that forks in two, the sum of the sections of the bifurcations must be equal to the surface of the suction tube in the bow.

    Embodiment
    The execution will be carried out at the time of construction of the boat, after taking into account the invention in the design of the ship, so that the centers of gravity of the sections are appropriate to the type of ship to be built, the conduits being
    fundamental part of the ship's hull. Thus the design of the bow of the ship will be affected in a special way if it is decided to incorporate the solution of two suction intakes.
    20 Industrial application
    The application of this propulsion system is for any type of motorized mechanical propulsion vessel, regardless of the size of the ship.
