Description

Technical Field

[0001] The invention belongs to the field of power technology, and in particular relates to an air-guided self-driven power device. Background Art

[0002] In the aerospace field, there is a general demand for aircraft to be powered and have their posture adjusted, which is related to the flight accuracy and performance of the aircraft.

[0003] Usually, in order to improve the operating accuracy of the aircraft, various power devices are installed on the aircraft, such as a combination of gas servos, air servos, and liquid attitude and orbit control power devices. Although the above-mentioned setting method can meet the needs of practical applications to a certain extent; however, due to the many restrictions on the servos (synchronization with the engine, taking effect after reentry) and short working time, they cannot be fully controlled; and although the liquid attitude and orbit control power device is flexible in application and can be started multiple times, its structure is complex, the propellant is highly toxic, and the high-pressure inflation and detection are cumbersome, which does not meet the needs of rapid response.

[0004] In comparison, the solid attitude and orbit control power device uses solid propellant charge, which has the advantages of simple structure and short launch preparation time, but it also has the disadvantages of not having the ability to output thrust randomly and being unable to achieve thrust reversal, wide range and multi-step adjustment. Moreover, the solid attitude and orbit control power device uses solid propellant. Due to the constant change of propellant consumption, the mass, center of mass and moment of inertia of the aircraft will change dynamically with the flight time, affecting the accurate control of the flight attitude of the aircraft. In addition, various disturbances caused by deviations such as installation structure errors and aerodynamic drag further affect the control accuracy and performance of the power device.

[0029] Example: See also Figure 1 to Figure 10 The gas-guided self-propelled power device in the preferred embodiment of the present invention includes a base 1, a tailstock 2 is connected to the top of one end of the base 1, and a nozzle 5 is connected to the tailstock 2.

[0030] Specifically, one end of the nozzle 5 is an air jet inlet 501, which is sealed and assembled on 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 nozzle 502, which extends out of the outer surface of the tailstock 2 and is used to realize the injection of the driving airflow.

[0031] Meanwhile, a rotating bore 3 is provided on the tailstock 2 . The rotating bore 3 is connected to the inner wall surface of the tailstock 2 via a rotating shaft and can rotate around the axis relative to the tailstock 2 .

[0032] Correspondingly, an accommodating space is formed between the bottom of the rotary chamber 3 and the base 1 , and a driving mechanism 7 is arranged in the accommodating space for the rotary chamber 3 .

[0033] In detail, the rotary barrel 3 in the preferred embodiment includes a barrel body 301 with a cylindrical structure, the axis of the barrel body 301 is parallel to the axis of the nozzle 5, and a bullet bore 302 is axially opened at one end of the barrel body 301 away from the tail stock 2 for accommodating the charge 4, and the bullet bore 302 on the barrel body 301 is arranged in a plurality of circumferentially equidistantly.

[0034] For example, in Figure 1 In the preferred embodiment shown, the bullet bores 302 are preferably five circumferentially evenly spaced.

[0035] In more detail, an airflow outlet 304 is coaxially opened at one end of the barrel 301 close to the tailstock 2 corresponding to each bullet bore 302, so that each bullet bore 302 is connected to one airflow outlet 304. During the rotation of the rotating barrel 3, each bullet bore 302 rotates around the axis. When the bullet bore 302 provided with the charge 4 moves to align with the jet inlet 501 on the nozzle 5, as shown in FIG. Figure 4 As shown in the figure, by igniting / firing the charge 4 in the bullet bore 302, the jet airflow generated can be transported to the nozzle 5 through the airflow outlet 304 and ejected from the main nozzle 502 of the nozzle 5, completing the process of providing power for the device.

[0036] Furthermore, the driving mechanism 7 in the preferred embodiment is also driven by the jet airflow of the nozzle 5 .

[0037] Specifically, the driving mechanism 7 in the preferred embodiment is as follows: Figure 3 , Figure 5 As shown in , it includes a slide plate 701 arranged between the base 1 and the rotary chamber 3, and the slide plate 701 can reciprocate along the length direction of the base 1. At the same time, a driving cylinder 702 is arranged at one end of the slide plate 701 close to the tailstock 2, and the driving cylinder 702 is further preferably arranged at the bottom of the tailstock 2.

[0038] At the same time, a first auxiliary nozzle 503 is opened on the outer wall surface of the nozzle 5 corresponding to the driving cylinder 702. The first auxiliary nozzle 503 is connected to 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 jet from the nozzle 5 is input into the driving cylinder 702, the slide plate 701 can be pushed to move along the length direction of the base 1 (that is, the axial direction of the rotary barrel 3).

[0039] Correspondingly, an elastic member is provided at one end of the slide plate 701 away from the driving cylinder 702 . The elastic member is initially in a pre-compressed state and can press the slide plate 701 tightly against the output end of the driving cylinder 702 .

[0040] In a preferred embodiment, the elastic member is at least one recoil spring 704 whose axis is parallel to the axis of the rotating chamber 3. For example, in a specific preferred embodiment, there are two recoil springs 704 arranged side by side, acting on both ends of the slide plate 701 in the width direction (horizontal direction perpendicular to the reciprocating motion direction of the slide plate 701).

[0041] More preferably, in order to better ensure the reciprocating motion of the slide plate 701, a guide rod 703 is preferably provided corresponding to each recoil spring 704, and the two ends of each guide rod 703 are respectively fixed on the base 1, and the slide plate 701 is slidably assembled on each guide rod 703, and can perform axial reciprocating sliding under the guidance of each guide rod 703.

[0042] Correspondingly, each recoil spring 704 is sleeved on the corresponding guide rod 703, and one end of each recoil spring 704 is limited and fixed, and the other end acts on the end surface of the slide plate 701. In this arrangement, when the slide plate 701 is driven by the driving cylinder 702 under the guidance of the guide rod 703 to perform recoil movement, the slide plate 701 continuously compresses each recoil spring 704, and when each recoil spring 704 is compressed to the limit, the movement of the slide plate 701 stops, and thereafter, under the action of the restoring force of each recoil spring 704, the slide plate 701 performs recoil movement and moves close to one end of the driving cylinder 702.

[0043] In actual setting, the length of the slide plate 701 corresponds to the length of the revolving chamber 3 , and the elastic force of the recoil spring 704 ensures that the slide plate 701 does not completely leave the projection range of the revolving chamber 3 .

[0044] In more detail, the top surface of the slide plate 701 is set as an arc surface matching the outer periphery of the bottom of the rotary chamber 3, and a "herringbone" slide groove is set on the arc surface, and the slide groove includes a first arc groove 7011 and a second arc groove 7012 respectively connected to both sides of the width direction of the slide plate 701, and a straight groove 7013 diffracted along the length direction of the slide plate 701 (i.e., the direction of the reciprocating motion of the slide plate 701). The straight groove 7013 is set in the middle of the slide plate 701, and one end thereof connects the two arc grooves, and the three form a Figure 5 , Figure 6 The herringbone shown in .

[0045] Correspondingly, a plurality of rotating rollers 303 are evenly spaced around the outer circumference of the chamber body 301 , and the number of rotating rollers 303 is the same as the number of bullet holes 302 , that is, the angle between two adjacent rotating rollers 303 is equal to the angle between two adjacent bullet holes 302 .

[0046] Further preferably, the extension line of the line connecting the center of each rotating barrel roller 303 and the center of the barrel body 301 passes through the center of a rotating barrel roller 303, that is, the center of the rotating barrel roller 303 and the center axis of the bullet bore 302 on the side away from the rotating barrel roller 303 and the center axis of the barrel body 301 are in the same radial plane. Such an arrangement can ensure that when the rotating barrel roller 303 is in the straight groove 7013 directly below the barrel body 301, the bullet bore 302 on the side away from the rotating barrel roller 303 is just above the rotating barrel roller 303.

[0047] Based on the above settings, the nozzle 5 on the tailstock 2 can be set accordingly, for example, the jet inlet 501 of the nozzle 5 is set to be aligned with the bullet bore 302 farthest from the base 1, such as Figure 7 as shown in .

[0048] Of course, according to actual setting requirements, the nozzle 5 can also be set to be aligned with other bullet bores 302, which will not be described in detail here.

[0049] Furthermore, a self-resetting guide 7014 is provided at the intersection of the three grooves of the herringbone slide groove. The self-resetting guide 7014 can be shifted between the ends of the two arc grooves, and the position of the self-resetting guide 7014 when not subjected to external force can be determined according to the rotation direction of the rotary barrel 3.

[0050] At the same time, an elastic member is provided at the bottom of the self-resetting guide member 7014 for always applying a force toward the end of the corresponding arc groove to the self-resetting guide member 7014, and the elastic member is further preferably a spring.

[0051] For example, in Figure 5 , Figure 8 In the preferred embodiment shown in , the rotary chamber 3 runs 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 groove 7012, and after the rotary chamber roller 303 enters the second arc groove 7012 from the end of the second arc groove 7012 away from the straight groove 7013, the self-resetting guide 7014 can be pushed toward the end side of the first arc groove 7011 at the intersection of the three grooves. Thereafter, the rotary chamber roller 303 enters the straight groove 7013, and after the rotary chamber roller 303 releases contact with the self-resetting guide 7014, the self-resetting guide 7014 resets to the end side of the second arc groove 7012 under the action of the elastic member. In this way, when the slide plate 701 performs a reciprocating motion, it can be limited by the self-resetting guide 7014, so that it can accurately run into the first arc groove 7011, and finally slide out from the end of the first arc groove 7011 away from the straight groove 7013.

[0052] like Figure 8~Figure 10As shown in , a schematic diagram of the entire process of a single recoil movement is provided. Figure 8 In the state of , the slide plate 701 is located directly below the rotary chamber 3. At this time, the rotary chamber roller 303 at the bottom of the rotary chamber 3 is embedded in the end of the linear groove 7013, and the bullet hole 302 loaded with the powder column 4 at the firing position is aligned with the nozzle 5 and the firing locking unit 801; thereafter, the powder column 4 is fired, and the driving cylinder 702 provides power to drive the slide plate 701 to start recoil, and the state is converted to Fig. 9 In the form of, at this time, the rotary roller 303 originally in the straight groove 7013 enters the first arc groove 7011, and the rotary barrel 3 starts to rotate; when the slide plate 701 recoils to the farthest position, the rotary roller 303 located in the first arc groove 7011 just leaves the first arc groove 7011, and at this time, another adjacent rotary roller 303 just enters the end of the second arc groove 7012.

[0053] With the restoring force of the recoil spring 704, the slide plate 701 starts to recoil, at which time, the revolving chamber 3 continues to rotate, and the revolving chamber roller 303 moves in the second arc groove 7012, and after moving to the end, pushes the self-resetting guide 7014 to the end of the first arc groove 7011, after which the revolving chamber roller 303 enters the linear groove 7013, and the slide plate 701 returns to its original position. Accordingly, the bullet bore 302 for the next firing rotates to the firing position and is aligned with the firing lock unit 801.

[0054] After completing a single recoil movement and a single return movement, the revolver 3 rotates through the angle between two adjacent bullet bores 302 to complete the alignment of different bullet bores 302 and different powder columns 4 with the firing mechanism 8 and the nozzle 5 in sequence.

[0055] Further preferably, a buffer rod 705 is provided at the end of the slide plate 701 away from the driving cylinder 702, and a buffer table 706 is provided at the end of the base 1 away from the tail stock 2. By matching the buffer rod 705 and the buffer table 706, buffering is achieved when the slide plate 701 moves to the extreme position, and the slide plate 701 is prevented from being unmatched from the rotary roller 303 on the rotary barrel 3.

[0056] Furthermore, a firing mechanism 8 is provided corresponding to the firing of the medicine column 4 in the rotating chamber 3, which includes a firing locking unit 801. The firing locking unit 801 is arranged on the side of the rotating chamber 3 away from the tail stock 2, is coaxially arranged with the nozzle 5, and is electrically connected to the control mechanism through a cable 803.

[0057] In actual configuration, the firing locking unit 801 is disposed on the inner side of the outer shell 9 , and is coaxially aligned with the nozzle 5 when the outer shell 9 is covered on the outer side of the rotating barrel 3 and connected to the base 1 .

[0058] Preferably, to ensure the reliability of the use of the firing lock unit 801, in actual setting, the firing lock unit 801 is connected to a displacement mechanism that can be axially telescopic by a small distance. When the cable 803 is powered, the firing lock unit 801 moves toward the turret 3, presses against the end of the corresponding bullet bore 302, and then completes the firing operation. After the cable 803 is powered off, the firing lock unit 801 automatically moves away from the surface of the turret 3 to avoid interfering with the rotation of the turret 3.

[0059] Exemplarily, in actual settings, the displacement mechanism corresponding to the firing lock unit 801 is an electromagnetic elastic member, and may further preferably be an electromagnetic pusher or an electromagnetic pin puller, and the displacement control of the firing lock unit 801 is completed by power on and off control.

[0060] In actual operation, it is preferred to pre-fill each bullet bore 302 with a charge 4, i.e., a preset charge 401. By firing each charge 4 and rotating the rotary chamber 3, multiple drives of the power device can be achieved, and switching of different charge 4 can be achieved in the form of gas-guided self-drive, thereby simplifying the rotary drive mechanism of the rotary chamber 3 and improving the compactness of the device.

[0061] More preferably, in actual setting, a firing safety unit 802 is preferably provided in the firing mechanism 8, which is preferably provided on the outer peripheral wall surface of the chamber body 301 and radially connected with the bullet bore 302; at the same time, a conduction unit is provided on the outer shell 9 corresponding to each firing safety unit 802, and after the rotating chamber 3 moves into place, the conduction unit is connected with the firing safety unit 802, and then the firing safety unit 802 can be used to fire the drug column 4.

[0062] Further preferably, in order to avoid insufficient driving power for the rotary chamber 3 due to incomplete combustion of the powder column 4, an auxiliary starting mechanism 10 is preferably provided on the tailstock 2, which preferably includes an ignition powder column that can be ignited separately, and the air outlet of the ignition powder column is connected to the air inlet of the driving cylinder 702. When the thrust of the combustion airflow in the bullet bore 302 is insufficient, the ignition powder column can be ignited to generate pressurized gas and transport it to the driving cylinder 702, which completes the driving process of the slide plate 701 and realizes the switching of different bullet bores 302.

[0063] Through the combined arrangement of the driving mechanism 7, the revolving chamber 3, the tailstock 2, the nozzle 5 and the firing mechanism 8, the bullet bore 302 loaded with the charge 4 can be ignited and fired by the firing mechanism 8 after being aligned with the nozzle 5, thereby realizing the provision of tail jet power and the self-driving control of the revolving chamber 3. After a single charge 4 is fired, the revolving chamber 3 can be driven accordingly with the aid of the jet gas generated after the ignition of the charge 4, and adaptively completes the position switching of different bullet bores 302 and the charge 4 therein, so as to facilitate the next firing operation, thereby realizing the continuous provision of tail jet power.

[0064] Furthermore, in actual settings, a drug delivery mechanism 6 is also provided for the rotating chamber 3, which is used to load the drug column 4 into the empty bullet bore 302, so as to further improve the performance of the power device and extend the time the power device provides power.

[0065] Specifically, the medicine delivery mechanism 6 in the preferred embodiment is as follows: Figure 1 , Figure 2 As shown in , it includes a bullet feed port 601 arranged on the shell 9, and the bullet feed port 601 is used to push the supplementary charge 402 whose axis is parallel to the axis of the rotating chamber 3 into the shell 9.

[0066] Correspondingly, a bullet-pulling wheel 602 is arranged at one end of the rotating chamber 3 away from the tailstock 2. The bullet-pulling wheel 602 is coaxially arranged on the central rotating shaft 603, and there are at least two bullet-pulling wheels 602 arranged axially at intervals, such as Figure 1 At the same time, one end of the central shaft 603 is fixedly connected to the center of the rotating chamber 3 and can rotate synchronously with the rotating chamber 3. Moreover, the bullet wheel 602 in the preferred embodiment is a star-shaped structure with a plurality of arc-shaped notches in the annular direction, and each arc-shaped notch is aligned with each bullet bore 302.

[0067] In actual configuration, a circular arc-shaped support plate is provided corresponding to the bullet inlet 601 to prevent the supplementary charge 402 from entering the housing 9 and falling onto the base 1. Based on the configuration of the support plate, the supplementary charge 402 horizontally fed from the bullet inlet 601 is embedded in a pair of arc-shaped notches and is circumferentially transposed following the movement of the bullet wheel 602.

[0068] In more detail, a two-stage push spring sheet is arranged on the side of the housing 9 away from the bullet inlet 601, namely a first push spring sheet 604 and a second push spring sheet 605, the two push spring sheets are arranged at intervals in the axial direction of the rotating chamber 3, the first push spring sheet 604 is arranged on the side of the second push spring sheet 605 away from the rotating chamber 3, and the bottoms of the two push spring sheets are respectively connected to the support arm. The support arm extends from the side of the slide plate 701 away from the tailstock 2, and through the recoil / return movement of the slide plate 701, the two push spring sheets can be driven to perform axial displacement accordingly.

[0069] It can be understood that when the slide plate 701 moves to the position farthest from the tailstock 2 , the first elastic push piece 604 moves to the first position, and the second elastic push piece 605 moves to the second position.

[0070] Furthermore, the end of the first push spring piece 604 extends above the supporting plate. When the first push spring piece 604 moves to the first position, a supplementary charge 402 can be delivered just between the first push spring piece 604 and the empty cartridge hole 302. In this way, when the slide plate 701 starts to return, the supplementary charge 402 can be pushed into the empty cartridge hole 302 through the first push spring piece 604.

[0071] In actual setting, the first push spring piece 604 is preferably set at a position that pushes half of the supplementary charge 402 into the bullet bore 302. After half of the charge is pushed in, the first push spring piece 604 contacts the end of the supplementary charge 402. However, due to inertia, the supplementary charge 402 will continue to move a certain distance into the bullet bore 302.

[0072] When the rotating barrel 3 continues to rotate, the bullet bore 302 to which the supplementary charge 402 is added moves to a position close to the second push spring piece 605. At this time, the end of the second push spring piece 605 is located in front of the supplementary charge 402. During another recoil process, the supplementary charge 402 is completely pushed into the bullet bore 302 by the second push spring piece 605. Thereafter, the bullet bore 302 into which the supplementary charge 402 is pushed can be aligned with the nozzle 5 and the firing lock unit 801 during the subsequent rotation process, thereby completing the firing process.

[0073] For example, for the preferred embodiment provided with the drug delivery mechanism 6, the bullet bore holes 302 are preferably 5 circumferentially evenly spaced, and correspondingly, the rotating barrel rollers 303 are also 5 circumferentially evenly spaced. At the same time, the bullet bore hole 302 in the firing position is preferably at the position farthest from the base 1, that is, when the bullet bore hole 302 moves to the top, it is aligned with the firing locking unit 801 and the nozzle 5.

[0074] In more detail, a chamber cleaning position is provided behind the firing position of the rotating chamber 3 for cleaning the unburned powder column 4 in the bullet bore 302 after firing, namely, the chamber cleaning powder column 403.

[0075] Corresponding to the setting of the clearing position, it is preferred that a clearing tube 606 is provided corresponding to the ejector wheel 602, and an elastic member is provided on the side of the clearing tube 606 away from the ejector wheel 602. The elastic member always provides an elastic force pointing to the ejector wheel 602 to the clearing tube 606, ensuring that after the ejector wheel 602 rotates to the position following the rotating barrel 3, the clearing tube 606 is always pressed in the arc-shaped notch aligned with the clearing position.

[0076] Correspondingly, a cleaning pipeline is provided on the tailstock 2 for the bullet bore 302 corresponding to the cleaning position, and the cleaning pipeline is connected to the second auxiliary nozzle 504 opened on the outer periphery of the nozzle 5, and is used to guide the airflow in the nozzle 5 to the cleaning position through the cleaning pipeline, and push the unburned cleaning charge 403 from the side of the bullet bore 302 close to the tailstock 2 to the cleaning pipe 606, and finally discharge it from the device.

[0077] More specifically, corresponding to the arrangement of the components on the base 1, a housing 9 is provided, which is detachably connected to the base 1 and encapsulates the components between the housing 9 and the base 1. In actual arrangement, the housing 9 is preferably divided into a first shell 901 and a second shell 902, the first shell 901 covers the rotating chamber 3, and the second shell 902 covers the medicine delivery mechanism 6 and realizes the closure of the end away from the tailstock 2.

[0078] It can be understood that in actual configuration, it is preferred to provide a cleaning outlet 903 at the end of the second shell 902 , and the cleaning outlet 903 can be aligned with the cleaning tube 606 inserted into the arc-shaped notch, thereby assisting in the discharge of the cleaning charge 403 .

[0079] For the gas-guided self-propelled power device in the preferred embodiment, it can be filled with preset medicine columns 401 in each bullet bore 302 before setting, and the self-driving of the rotating chamber 3 is realized by firing the preset medicine columns 401, and each preset medicine column 401 is accurately switched to align with the firing mechanism 8, and the continuous provision of tail jet power is completed in sequence. Moreover, based on the setting of the medicine delivery mechanism 6, after each preset medicine column 401 is fired, the supplementary medicine column 402 can be accurately filled into the bullet bore 302, thereby further improving the power device's ability to provide power and extending the service life of the power device.

[0080] The gas-guided self-propelled power device of the present invention has a compact structure and is easy to use. It can accurately realize the power output of the power device and complete the position switching of different bullet bores in the form of gas-guided self-drive while outputting power, 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 has good practical value.

[0081] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
