    Detailed description Reference will now be made in detail to the embodiments of the present invention, examples of which are described below and illustrated in the drawings accompanying the present application. Although the present invention is described in connection with embodiments and / or examples, it is understood that they are not intended to limit the present invention to these embodiments and / or examples. On the contrary, the present invention aims to cover variants, modifications and equivalences.
    In some cases, an aerial refueler ramp operator can rely solely on visual cues to estimate the articulation angle of a ball joint of a fluid nozzle. A fluid nozzle may have a limited amount of articulation and, exceeding this limit, may cause damage to the refueling aircraft and / or the receiving aircraft. In addition, an excessive articulation angle when attempting to disengage the supply aircraft from the receiving aircraft may be an indication that the fluid nozzle is blocked in the receptacle.
    In embodiments, as illustrated generally in FIGS. 1 to 3, a fluid nozzle 20 (for example a ramp nozzle) can be configured to connect a first fluid conduit 22 (for example a ramp of a refueling aircraft) to a second fluid conduit 24 (for example a receptacle of a receiving aircraft). A fluid nozzle 20 may include an inlet housing 30 and an outlet housing 32. The inlet housing 30 may be configured to be connected to the first fluid conduit 22. The outlet housing 32 may be configured to be connected to the second fluid conduit 24. The outlet housing 32 can be configured to articulate with respect to the inlet housing 30. For example and without limitation, the inlet housing 30 and the outlet housing 32 can be connected by through a ball joint arrangement. The inlet housing 30 of the fluid nozzle 20 may be attached to the first fluid conduit 22 (e.g., a ramp of a refueling aircraft) and the outlet housing 32 of the fluid nozzle 20 may be free up to that it is inserted into or connected to the second fluid conduit 24 (eg, the receptacle of a receiving aircraft).
    In embodiments, a fluid nozzle 20 can include one or more articulation angle sensors 34 in several planes which can provide information relating to an angle of the outlet housing 32 relative to the housing input 30. An articulation sensor 34 can comprise a magnetic sensor 36 (eg a Hall effect sensor) and a magnet 38 (eg a permanent annular magnet). The magnetic sensor 36 can be placed in a dry part 40 of the inlet housing 30 and can be arranged or oriented so that the magnetic sensor 36 can detect the magnet 38, which can be placed or installed on or around a edge of the interface of the ball joint 42 of the outlet housing (see, for example, FIGS. 1 to 3). For example, and without limitation, the magnetic sensor 36 may be disposed adjacent to an external surface of the inlet housing 30 and the magnet 38 may be disposed adjacent to an external surface of the outlet housing 32. The at least one magnetic sensors 36 can be directed towards the outlet housing 32 and / or be arranged at an acute angle relative to an axial direction. As the outlet housing 32 articulates with respect to the inlet housing 30, the magnetic sensor or sensors 36 can detect a change in magnetic field resulting from the movement of the magnet 38 with the outlet housing 32 and the magnetic sensor or sensors 36 can provide information associated with the tailor-delighted aircraft. This information can then be translated (for example by an electronic control unit or ECU 44 of the supply aircraft) into articulation angles for each of one or more displacement planes, which can be translated collectively or independently.
    In embodiments, as illustrated generally in FIGS. 4 to 6, an articulation sensor 50 of a fluid nozzle 20 can comprise one or more magnetic sensors 52 (for example Hall effect sensors or proximity switches) and / or one or more magnets 54 (by permanent ring magnets). A magnetic sensor 52 can be disposed in a dry portion 56 of the inlet housing 30 and can be oriented so that the magnetic sensor 52 can detect or pick up a magnet 54 which can be disposed on or around an edge of a ball joint base 58. The magnetic sensor 52 can, for example and without limitation, be substantially aligned with a radial direction and / or be directed radially inwards. The ball joint base 58 can be slidably connected to the inlet housing 30. Any articulation angle, regardless of the plane, can cause the ball joint base 58 to perform linear translation. As the outlet housing 32 articulates with respect to the inlet housing 30, the magnetic sensor (s) 52 can detect a change in the magnetic field due to the magnet 54 moving with the seal base ball 58 closer (or further) to the sensor (s) 52. The sensor 52 can provide this information to the supply aircraft. This information can then be translated into an articulation angle (for example by an electronic control unit or ECU 44 of the supply aircraft).
    An aerial refueler can for example rely on “contact” and “ready state” sensors in a receptacle of the receiving aircraft ramp nozzle to confirm or determine that the nozzle and the receptacle are correctly connected and that it is safe to start the transfer of fluid / fuel A problem may occur if the receptacle sensors do not work and / or if a poor voice coil in the receptacle or nozzle prevents the signal from the receiver from properly reaching a refueler. When this happens, a tanker operator can visually determine if the nozzle and the receptacle are connected and manually advance the "contact" and "ready state" signals. In some cases, the nozzle and the receptacle may appear visually connected, but in reality may not be sufficiently or correctly connected. If the nozzle and the receptacle are not sufficiently or correctly connected, the nozzle can drift out of the receptacle, which can place the nozzle in the immediate vicinity of the receiving aircraft where it could, under certain circumstances, damage the receiving aircraft, as in the case where the nozzle and the receiving aircraft come into contact.
    In embodiments, as illustrated generally in FIGS. 7 to 9, a fluid nozzle 20, which can be configured as an aerial fueling nozzle or a ramp nozzle, can include one or more contact sensors 60, which can provide the same or similar "contact" signals to those of the sensors of a receptacle 24. The contact sensor or sensors 60 can supply “contact” signals independently of the receptacle sensors of the receiving aircraft. With such configurations, "contact" signals can be provided even if the sensors of the receiving aircraft do not work and / or if a poor voice coil prevents the refueller from receiving the signals. An ECU 44 can be configured to determine a contact state of the fluid nozzle 20 as a function of the "contact" signal coming from the contact sensor (s) 60.
    In embodiments, a contact sensor 60 can comprise a switch 62, such as a hermetically sealed proximity switch (eg a magnetic or Hall effect sensor), which can be installed, for example, in a cavity 64 on a dry side of the outlet housing 32. The contact sensor 60 can, for example and without limitation, be substantially aligned with an axial direction and / or be directed away from the inlet housing 30. In embodiments, the contact sensor 60 can be activated by a magnet 66 (eg, a permanent magnet) which can be connected to and / or incorporated into a mushroom 68 of the fluid nozzle 20. The mushroom 68 can perform a translation between open and closed positions to regulate a flow of fluid through the fluid nozzle 20. The mushroom 68 can be biased towards the closed position by a mushroom spring 70.
    If the fluid nozzle 20 is inserted into the ramp receptacle of the receiver 24, a valve of the base 72 of the receptacle 24 can push the mushroom 68 of the fluid nozzle 20 towards the open position. When the mushroom 68 travels a certain running distance (e.g., from about 0.75 inch to 1.25 inch, such as from about 0.84 inch) and beyond, the proximity switch 62 can open or close, depending on the configuration, and can provide a "contact" signal. The configuration of the proximity switch 62 (e.g. normally open or normally closed) may be dictated by the environment and / or the preference of the boom nozzle operator. When the tanker receives the "contact" signal, the tanker can know / confirm that the receptacle 24 is sufficiently or correctly installed in the fluid nozzle 20.
    In embodiments, as illustrated generally in FIGS. 10 and 11, a fluid nozzle 20 may include one or more ready state sensors 80 which can provide the same "ready state" signal or a signal similar to that of the boom nozzle receptacle 24 and can provide more high accuracy of positively engaging the receptacle rollers 82 in the nozzle latches 84. An ECU can be configured to determine a ready state of the fluid nozzle 20 based on the "ready state" signal from the at least one ready state sensors 80. The ready state sensor (s) 80 of the fluid nozzle 20 can provide "ready state" signals independent of the receptacle sensors of the receiving aircraft, so that the signals "d 'ready state' can be provided even if the sensors of the receiving aircraft do not work and / or if a bad voice coil prevents the refueller from receiving the signals. Embodiments of fluid nozzles 20 can directly detect the positive engagement of the receptacle rollers 82 in the nozzle latches 84 through a ready state sensor 80.
    In embodiments, as illustrated generally in Figures 10 and 11, a ready state sensor 80 may include a switch 86, such as a tightly closed switch (eg, a microphone -switch), which can be installed in a cavity 88 outside the outlet housing 32. The ready status sensor 80 can include a locking indication trigger 90 which can be configured to activate and / or deactivate the switch 86. The lock indication trigger (s) 90 may be hinged and spring loaded, holding a switch 86 button down when the receptacle rollers 82 are not fully engaged with the nozzle latches 84. As the receptacle rollers 82 begin to close on the nozzle latches 84, the receptacle rollers 82 may come into contact with the lock indication trigger (s) 90. The trigger (s) lock indication nippers 90 can be hinged and / or spring loaded and the lock indication trigger (s) 90 can move with the receptacle rollers 82 and enter a slot 92 in the nozzle latches 84. Once the receptacle rollers 82 are fully housed in the nozzle latches 84, the lock indication trigger (s) 90 can release the button (s) on the switch (s) 86.
    In embodiments, a lock indication trigger 90 may include one or more of different configurations. For example and without limitation, a locking indication trigger 90 may comprise a first branch 100, a second branch 102 and / or a third branch 104. The second branch 102 can connect the first branch 100 and the third branch 104, which can be arranged substantially parallel to each other. The third branch 104 may be longer than a combined length of the first branch 100 and the second branch 102. A locking indication trigger 90 may be rotatably connected to a nozzle latch 84. The first branch 100 can be configured to contact and / or activate a switch 86. The third branch 104 can be configured to engage with and / or be rotated by a locking roller 82 of the receptacle 24. In an initial position of a die lock indication actuator 90, the third branch 104 may extend at least partially radially beyond a nozzle latch 84 and / or extend outside a slot 92 (see e.g. , FIG. 10). As the fluid nozzle 20 is connected to the receptacle 24, a locking roller 82 of the receptacle 24 can roll over a nozzle latch 84 of the fluid nozzle 20 and come into contact with the third leg 104 of a lock indication trigger 90, which may cause the lock indication trigger 90 to rotate to a second position. In the second position, the locking indication trigger 90 can activate or deactivate a switch 86. In the second position, the third branch 104 can, for example and without limitation, be arranged substantially parallel to an axial direction and / or can be disposed substantially in the slot 92 (see for example FIG. 11).
    In embodiments, the switch 86 can be normally open or normally closed, depending on the configuration and / or the preference of the operator of the boom nozzle. When the tanker (eg, an ECU 44 associated with the tanker) receives the "ready state" signal, the tanker / ECU 44 can know / confirm that the fluid nozzle 20 and the receptacle 24 are correctly coupled and can start fluid / fuel transfer.
    In embodiments, a method of connecting a fluid nozzle 20 with a receptacle 24 may include providing a fluid nozzle 20, providing a receptacle 24, moving the nozzle for fluid 20 to receptacle 24 (which may include sliding receptacle 24 in fluid nozzle 20), detecting contact between fluid nozzle 20 and receptacle 24 through a contact sensor 60 and / or detecting, via a ready state sensor 80, that the receptacle 24 is locked with the fluid nozzle 20. The contact sensor 60 may include a magnetic sensor 62 and a magnet 66. L the magnet 66 can be connected to a mushroom 68 of the fluid nozzle 20. The detection of the contact between the fluid nozzle 20 and the receptacle 24 can comprise the displacement of the magnet 66 towards the magnetic sensor 62. The sensor ready state 80 may include switch 86 and dec lock indication latch 90. Detection that the receptacle 24 is locked with the fluid nozzle 20 may include engaging a locking roller 82 of the receptacle 24 with the lock indication trigger 90 to cause the rotation of the locking indication trigger 90. The method can include the detection of a joint of the fluid nozzle 20 by means of a joint sensor 50. The joint sensor 50 can comprise a magnetic sensor 52 connected / fixed to the inlet housing 30 and a magnet 54 connected to the outlet housing 32 or to a ball joint base 58 of the inlet housing 30.
    Embodiments of nozzles 20 can facilitate automatic and / or autonomous aerial refueling because the refueling process may not involve visual cues to determine a nozzle articulation angle and relative positions tanker and receiver aircraft. For example and without limitation, an ECU 44 can automatically determine a hinge angle / position, a contact state and / or a ready state, such as through one or more hinge sensors 50, one or more than one contact sensor 60 and / or one or more ready state sensors 80. If the ECU 44 determines that the hinge angle is within an acceptable or predefined range (eg, about 30 degrees or less), that the contact sensor (s) 60 provide a contact signal and / or that the ready state sensor (s) 80 provide a ready state signal, the ECU 44 can automatically initiate refueling.
