[0002] In the field of aerospace, there is a common need for aircraft to be powered and pose-adjusted, which relates to the flight accuracy and use performance of the aircraft.

[0003] Generally, in order to improve the operation accuracy of the aircraft, various power devices are provided on the aircraft, such as a combination of a gas rudder machine, an air rudder machine, and a liquid attitude and orbit control power device. The foregoing setting mode can meet the needs of actual application to a certain extent; however, the rudder machine is limited by many conditions (synchronization with the engine, post-reentry effect), and cannot be controlled throughout the process; and the liquid attitude and orbit control power device is flexible in application, and can be started multiple times, but its structure is complex, the propellant is highly toxic, high-pressure inflation and detection are complicated, and it does not meet the needs of rapid response.

[0057] Embodiment:

[0058] Please refer to Figures 1-10 , the air guide self-driven power device in the preferred embodiment of the present application comprises a base 1, the top of one end of which is connected to a tailstock 2, and a nozzle 5 is connected to the tailstock 2.

[0059] Specifically, one end of the nozzle 5 is a jet inlet 501, which is sealingly and fittingly connected to the tailstock 2 and communicates with the inner wall surface of the tailstock 2; the other end of the nozzle 5 is provided with a main jet 502, which protrudes out of the outer surface of the tailstock 2, for realizing the jet of driving gas flow.

[0060] At the same time, a rotating chamber 3 is arranged on the tailstock 2, which is connected to the inner wall surface of the tailstock 2 through a rotating shaft and can rotate around the shaft relative to the tailstock 2.

[0061] Correspondingly, a containing space is formed between the bottom of the rotating chamber 3 and the base 1, and a driving mechanism 7 is arranged in the containing space for the rotating chamber 3.

[0062] In detail, the rotating chamber 3 in the preferred embodiment comprises a chamber body 301 in a cylindrical structure, the axis of which is parallel to the axis of the nozzle 5, and a cartridge bore 302 is axially arranged at one end of the chamber body 301 away from the tailstock 2 for accommodating the propellant 4, and the cartridge bores 302 on the chamber body 301 are circumferentially and equally spaced.

[0063] For example, in the preferred embodiment as shown in Figure 1 , the cartridge bores 302 are preferably five circumferentially and equally spaced.

[0064] More specifically, a gas flow outlet 304 is coaxially arranged at one end of the chamber body 301 close to the tailstock 2 corresponding to each cartridge bore 302, so that each cartridge bore 302 communicates with one gas flow outlet 304. In the rotating process of the rotating chamber 3, each cartridge bore 302 rotates around the shaft, and when the cartridge bore 302 provided with the propellant 4 moves to be aligned with the jet inlet 501 on the nozzle 5, as shown in Figure 4 , by igniting / firing the propellant 4 in the cartridge bore 302, the generated jet gas flow can be delivered to the nozzle 5 through the gas flow outlet 304, and then ejected by the main jet 502 of the nozzle 5, completing the process of providing power by the device.

[0065] Further, the driving mechanism 7 in the preferred embodiment is also driven by the jet gas flow of the nozzle 5.

[0066] Specifically, the driving mechanism 7 in the preferred embodiment is as shown in Figure 3 , Figure 5As shown in the figure, it comprises a slide plate 701 arranged between the base 1 and the rotating chamber 3, which can reciprocate along the length direction of the base 1. Meanwhile, a driving cylinder 702 is arranged at one end of the slide plate 701 close to the tailstock 2, which is further preferably arranged at the bottom of the tailstock 2.

[0067] Meanwhile, a first auxiliary nozzle 503 is arranged on the outer peripheral wall surface of the nozzle 5 corresponding to the driving cylinder 702, which is communicated with the driving cylinder 702 through a pipeline, and the driving cylinder 702 is assembled with one end of the slide plate 701, so that after the driving cylinder 702 inputs the jet gas from the nozzle 5, it can push the slide plate 701 to move along the length direction of the base 1 (i.e. the axial direction of the rotating chamber 3).

[0068] Correspondingly, an elastic member is arranged at one end of the slide plate 701 away from the driving cylinder 702, which is in a pre-compressed state at the beginning, and can tightly press the slide plate 701 against the output end of the driving cylinder 702.

[0069] In the preferred embodiment, the above-mentioned elastic member is at least one complex spring 704 with its axis parallel to the axis of the rotating chamber 3. For example, in a specific preferred embodiment, two complex springs 704 are arranged side by side, respectively acting on both ends of the slide plate 701 in the width direction (the horizontal direction perpendicular to the reciprocating direction of the slide plate 701).

[0070] More preferably, in order to better ensure the reciprocating movement of the slide plate 701, a guide rod 703 is preferably arranged corresponding to each complex spring 704, both ends of each guide rod 703 are fixed on the base 1, and the slide plate 701 is slidingly assembled on each guide rod 703, which can reciprocate axially under the guidance of each guide rod 703.

[0071] Correspondingly, each complex spring 704 is sleeved on the corresponding guide rod 703, and one end of each complex spring 704 is limitingly fixed, and the other end acts on the end face of the slide plate 701. In this way, when the slide plate 701 is driven by the driving cylinder 702 to move rearward under the guidance of the guide rod 703, each complex spring 704 is continuously compressed by the slide plate 701, and when each complex spring 704 is compressed to the limit, the movement of the slide plate 701 stops. Thereafter, under the action of the restoring force of each complex spring 704, the slide plate 701 moves forward to the end of the driving cylinder 702.

[0072] In actual arrangement, the length of the slide plate 701 corresponds to the length of the rotating chamber 3, and the elastic force of the complex spring 704 ensures that the slide plate 701 is always within the projection range of the rotating chamber 3.

[0073] In detail, the top surface of the slide plate 701 is arranged as a circular arc surface matching the bottom outer periphery of the rotating chamber 3, and a "herringbone" slide groove is arranged on the circular arc surface, which includes a first arc-shaped groove 7011 and a second arc-shaped groove 7012 respectively communicating with both sides of the width direction of the slide plate 701, and a straight groove 7013 arranged along the length direction of the slide plate 701 (i.e. the direction of reciprocating movement of the slide plate 701). The straight groove 7013 is arranged at the middle part of the slide plate 701, and one end thereof communicates with the two arc-shaped grooves, and the three form a herringbone as shown in Figure 5 、 Figure 6 .

[0074] Correspondingly, a plurality of rotating chamber rollers 303 are arranged on the outer periphery of the chamber body 301 in equal intervals in the circumferential direction, and the number of the rotating chamber rollers 303 is the same as the number of the cartridge holes 302, i.e. the angle between two adjacent rotating chamber rollers 303 is equal to the angle between two adjacent cartridge holes 302.

[0075] Further preferably, the extension line of the line connecting the center of each rotating chamber roller 303 with the center of the chamber body 301 passes through the center of one rotating chamber roller 303, i.e. the center of the rotating chamber roller 303, the central axis of the cartridge hole 302 on the side away from the rotating chamber roller 303 and the central axis of the chamber body 301 are in the same radial plane, and in this way, when the rotating chamber roller 303 is in the straight groove 7013 directly below the chamber body 301, the cartridge hole 302 on the side away from the rotating chamber roller 303 is just directly above the rotating chamber roller 303.

[0076] Based on the above arrangement, the setting of the nozzle 5 on the tailstock 2 can be completed, for example, the jet inlet 501 of the nozzle 5 is arranged in the form of being aligned with the cartridge hole 302 farthest from the base 1, as shown in Figure 7 .

[0077] Of course, according to the actual setting requirements, the nozzle 5 can also be arranged in the form of being aligned with other cartridge holes 302, which is not described here.

[0078] Further, a self-resetting guide 7014 is arranged at the intersection of the three grooves of the herringbone slide groove, which can be transposed between the end portions of the two arc-shaped grooves, and the position of the self-resetting guide 7014 when not subjected to external force can be determined according to the rotating direction of the rotating chamber 3.

[0079] Meanwhile, an elastic member is arranged at the bottom of the self-resetting guide 7014 for always applying an acting force to the self-resetting guide 7014 towards the end portion of the corresponding arc-shaped groove, and the elastic member is further preferably a spring.

[0080] Exemplarily, as shown in Figure 5 、 Figure 8In the preferred embodiment shown in the figure, the chamber 3 operates in a counterclockwise rotation, at this time, the initial position of the self-resetting guide 7014 when not subjected to external force is close to the end of the second arc-shaped groove 7012, and after the chamber roller 303 enters the second arc-shaped groove 7012 from the end of the second arc-shaped groove 7012 away from the straight groove 7013, it can push the self-resetting guide 7014 to the end of the first arc-shaped groove 7011 on one side when it reaches the three-groove intersection, and then the chamber roller 303 enters the straight groove 7013, and after the chamber roller 303 is out of contact with the self-resetting guide 7014, the self-resetting guide 7014 is reset to the end of the second arc-shaped groove 7012 on one side under the action of the elastic member. In this way, when the slide plate 701 performs a return motion, it can be limited by the self-resetting guide 7014, so as to accurately operate into the first arc-shaped groove 7011, and finally slide out from the end of the first arc-shaped groove 7011 away from the straight groove 7013.

[0081] As shown in the figure, Figures 8-10 The whole process of single recoil motion is provided. Among them, in the state of Figure 8 , the slide plate 701 is located directly below the chamber 3, at this time, the chamber roller 303 at the bottom of the chamber 3 is embedded in the end of the straight groove 7013, the firing position is aligned with the barrel hole 302 filled with the cartridge 4, the nozzle 5 and the firing locking unit 801; then, the cartridge 4 is fired, the driving cylinder 702 provides power to drive the slide plate 701 to start the recoil, and the state is converted to Figure 9 , at this time, the chamber roller 303 originally in the straight groove 7013 enters the first arc-shaped groove 7011, and the chamber 3 starts to rotate; when the slide plate 701 recoils to the farthest position, the chamber roller 303 in the first arc-shaped groove 7011 just leaves the first arc-shaped groove 7011, and at this time, the other adjacent chamber roller 303 just enters the end of the second arc-shaped groove 7012.

[0082] With the restoring force of the return spring 704, the slide plate 701 starts to return, at this time, the chamber 3 continues to rotate, the chamber roller 303 moves in the second arc-shaped groove 7012, and pushes the self-resetting guide 7014 to the end of the first arc-shaped groove 7011 on one side after moving to the end, and then the chamber roller 303 enters the straight groove 7013, and the slide plate 701 returns. Correspondingly, the barrel hole 302 for the next firing is rotated to the firing position and aligned with the firing locking unit 801.

[0083] After completing single recoil motion and single return motion, the chamber 3 rotates through the angle between the adjacent two barrel holes 302, and completes the alignment of different barrel holes 302 and different cartridges 4 with the firing mechanism 8 and the nozzle 5.

[0084] Further preferably, a buffer rod 705 is arranged at the end of the slide plate 701 away from the driving cylinder 702, and a buffer platform 706 is arranged at the end of the base 1 away from the tailstock 2, and the buffer rod 705 and the buffer platform 706 are matched to achieve buffering when the slide plate 701 moves to the limit position, and to avoid the disengagement of the slide plate 701 and the rotating chamber roller 303 on the rotating chamber 3.

[0085] Further, a firing mechanism 8 corresponding to the firing of the propellant column 4 in the rotating chamber 3 is also provided, which includes a firing locking unit 801 arranged on the side of the rotating chamber 3 away from the tailstock 2, coaxially arranged with the nozzle 5, and electrically connected to the control mechanism through a cable 803.

[0086] In actual arrangement, the firing locking unit 801 is arranged inside the shell 9, which is coaxially aligned with the nozzle 5 when the shell 9 is arranged outside the rotating chamber 3 and connected to the base 1.

[0087] Preferably, in order to ensure the reliability of the use of the firing locking unit 801, in actual arrangement, the firing locking unit 801 is connected to a displacement mechanism that can be axially stretched and contracted by a small distance, and under the condition of power supply of the cable 803, the firing locking unit 801 moves towards the rotating chamber 3, and is pressed against the end of the corresponding chamber hole 302, and then completes the firing operation. After the cable 803 is powered off, the firing locking unit 801 automatically moves away from the surface of the rotating chamber 3 to avoid interfering with the rotation of the rotating chamber 3.

[0088] Illustratively, in actual arrangement, the displacement mechanism corresponding to the firing locking unit 801 is an electromagnetic elastic element, which can be further preferably an electromagnetic pusher or an electromagnetic puller, and the displacement control of the firing locking unit 801 is completed by controlling the power supply.

[0089] In actual work, preferably, a pre-set propellant column 401 is arranged in each chamber hole 302, and through the separate firing of each propellant column 4 and the rotation switching of the rotating chamber 3, multiple driving of the power device can be achieved, and different propellant columns 4 can be switched in a gas-guided self-driving manner, thereby simplifying the rotary driving mechanism of the rotating chamber 3 and improving the compactness of the device.

[0090] More preferably, in actual arrangement, a firing safety unit 802 is preferably arranged on the outer peripheral wall surface of the chamber body 301 and is in radial communication with the chamber hole 302, and a communication unit corresponding to each firing safety unit 802 is arranged on the shell 9, and after the rotating chamber 3 is moved into position, the communication unit is in communication with the firing safety unit 802, and the propellant column 4 can be fired through the firing safety unit 802.

[0091] Further preferably, in order to avoid insufficient driving power of the rotating chamber 3 due to insufficient combustion of the propellant 4, an auxiliary starting mechanism 10 is preferably arranged on the breechblock 2, which preferably comprises a separately ignitable ignition propellant, the gas outlet of which is in communication with the gas inlet of the driving cylinder 702, and when the gas flow is insufficient in the cartridge bore hole 302, the ignition propellant can be ignited to generate pressure gas and deliver it to the driving cylinder 702 to complete the driving process of the slide plate 701, thereby achieving the switching of different cartridge bore holes 302.

[0092] By the combined arrangement of the driving mechanism 7, the rotating chamber 3, the breechblock 2, the nozzle 5 and the firing mechanism 8, the cartridge bore hole 302 loaded with the propellant 4 can be ignited and fired by the firing mechanism 8 after being aligned with the nozzle 5, thereby achieving the provision of the tail jet power and the self-driving control of the rotating chamber 3, so that after the single propellant 4 is fired, the rotating chamber 3 can be correspondingly driven by the jet gas generated after the ignition of the propellant 4, and the switching of different cartridge bore holes 302 and the propellants 4 therein is adaptively completed, so as to facilitate the next firing operation, thereby achieving the continuous provision of the tail jet power.

[0093] Further, in actual arrangement, the feeding mechanism 6 is arranged for the rotating chamber 3, which is used to load the propellant 4 into the empty cartridge bore hole 302, thereby further improving the use performance of the power device and prolonging the time of power provision.

[0094] Specifically, the feeding mechanism 6 in the preferred embodiment is as shown in Figure 1 、 Figure 2 , which comprises a cartridge inlet 601 arranged on the housing 9, which is used to push the supplementary propellant 402 with the axis parallel to the axis of the rotating chamber 3 into the housing 9.

[0095] Correspondingly, the cartridge ejector wheel 602 is arranged at the end of the rotating chamber 3 away from the breechblock 2, which is coaxially arranged on the central rotating shaft 603 and is axially spaced apart at least two, as shown in Figure 1 . Meanwhile, one end of the central rotating shaft 603 is fixedly connected to the center of the rotating chamber 3 and can synchronously rotate with the rotating chamber 3. Moreover, the cartridge ejector wheel 602 in the preferred embodiment is a star-shaped structure with a plurality of arc-shaped notches opened in the ring direction, and each arc-shaped notch is aligned with each cartridge bore hole 302.

[0096] In actual arrangement, the arc-shaped supporting plate is arranged corresponding to the cartridge inlet 601 to avoid the supplementary propellant 402 from falling onto the base 1 after entering the housing 9. Based on the arrangement of the supporting plate, the supplementary propellant 402 horizontally sent from the cartridge inlet 601 is embedded in a certain arc-shaped notch and follows the movement of the cartridge ejector wheel 602 for ring direction transposition.

[0097] More specifically, two-stage bullet pushing plates, i.e. a first bullet pushing plate 604 and a second bullet pushing plate 605, are arranged in the housing 9 away from the bullet inlet 601, and the two bullet pushing plates are arranged in axial direction of the rotating chamber 3, the first bullet pushing plate 604 is arranged on the side of the second bullet pushing plate 605 away from the rotating chamber 3, and the bottoms of the two bullet pushing plates are connected to the supporting arms respectively. The supporting arms extend from the side of the slide plate 701 away from the breechblock 2, and the rearward movement of the slide plate 701 can correspondingly drive the two bullet pushing plates to move axially.

[0098] It can be understood that when the slide plate 701 moves to the position farthest from the breechblock 2, the first bullet pushing plate 604 moves to the first position and the second bullet pushing plate 605 moves to the second position.

[0099] Further, the end of the first bullet pushing plate 604 extends above the supporting plate, and when the first bullet pushing plate 604 moves to the first position, a supplemental propellant column 402 can be fed between the first bullet pushing plate 604 and the empty bullet chamber hole 302, so that when the slide plate 701 starts to move backward, the supplemental propellant column 402 can be pushed into the empty bullet chamber hole 302 by the first bullet pushing plate 604.

[0100] In actual arrangement, the first bullet pushing plate 604 is preferably arranged to push half of the supplemental propellant column 402 into the bullet chamber hole 302, and after pushing half of the supplemental propellant column 402, the first bullet pushing plate 604 contacts the end of the supplemental propellant column 402. However, due to inertia, the supplemental propellant column 402 will continue to move a certain distance into the bullet chamber hole 302.

[0101] When the rotating chamber 3 continues to rotate, the bullet chamber hole 302 with the added supplemental propellant column 402 moves to the position close to the second bullet pushing plate 605, at this time, the end of the second bullet pushing plate 605 is located in front of the supplemental propellant column 402, and during the next backward movement, the supplemental propellant column 402 is completely pushed into the bullet chamber hole 302 by the second bullet pushing plate 605. After that, the bullet chamber hole 302 with the supplemental propellant column 402 can be aligned with the nozzle 5 and the firing lock unit 801 during subsequent rotation, thereby completing the firing process.

[0102] For example, for the preferred embodiment provided with the propellant feeding mechanism 6, the bullet chamber holes 302 are preferably 5 annularly and equally spaced, and correspondingly, the rotating chamber rollers 303 are also 5 annularly and equally spaced. Meanwhile, the bullet chamber hole 302 in the firing position is preferably the one farthest from the base 1, i.e. when the bullet chamber hole 302 moves to the topmost position, it is aligned with the firing lock unit 801 and the nozzle 5.

[0103] More specifically, a clearing position is arranged behind the firing position of the rotating chamber 3, for clearing the propellant column 403 that is not burnt out in the bullet chamber hole 302 after the completion of the firing.

[0104] Corresponding to the setting of the clearing position, preferably corresponding to the ejector wheel 602 is provided with a clearing tube 606, which is provided with an elastic element on the side away from the ejector wheel 602, and the elastic element always provides an elastic force to the clearing tube 606, which is always pressed in the arc-shaped notch aligned with the clearing position after the ejector wheel 602 is rotated to the position following the rotating chamber 3.

[0105] Corresponding to the clearing position of the cartridge chamber 302, the tailstock 2 is provided with a clearing tube, which is in communication with the second auxiliary nozzle 504 opened on the outer periphery of the nozzle 5, and is used to guide the gas flow in the nozzle 5 to the clearing position through the clearing tube, and push the unburned clearing propellant 403 from the side of the cartridge chamber 302 close to the tailstock 2 to the clearing tube 606, and finally discharged from the device.

[0106] Further specifically, corresponding to the setting of each component on the base 1, the cover is provided with an outer shell 9, which is detachably connected with the base 1 and encapsulates each component between the outer shell 9 and the base 1. In actual setting, preferably the outer shell 9 is divided into a first shell body 901 and a second shell body 902, the rotating chamber 3 is covered by the first shell body 901, and the feeding mechanism 6 and the end away from the tailstock 2 are covered by the second shell body 902.

[0107] It can be understood that in actual setting, the end of the second shell body 902 is preferably provided with a clearing outlet 903, which can be aligned with the clearing tube 606 clamped in the arc-shaped notch, thereby assisting in completing the discharge of the clearing propellant 403.

[0108] For the gas-guiding self-driven power device in the preferred embodiment, each cartridge chamber 302 is preferably filled with a preset propellant 401 before setting, and the self-driving of the rotating chamber 3 is realized by the firing of the preset propellant 401, the accurate switching of each preset propellant 401 to be aligned with the firing mechanism 8, and the sequential completion of the continuous provision of the tail jet power. Moreover, based on the setting of the feeding mechanism 6, after each preset propellant 401 is fired, a supplemental propellant 402 can be accurately filled into the cartridge chamber 302, thereby further improving the power provision capability of the power device and prolonging the use time of the power device.

[0109] The gas-guiding self-driven power device of the present application has the advantages of compact structure, convenient use, accurate power output of the power device, and simultaneous switching of different cartridge chambers in the form of gas-guiding self-driving, thereby realizing the continuous switching of multiple propellants in the firing position, ensuring the continuity and reliability of the power provided by the power device, and having good practical value.

[0110] Those skilled in the art can easily understand that the above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
