[0002] In recent years, with the rapid development of micro-drones and loitering munitions, swarm system warfare has received increasing attention. Pneumatic catapult technology uses pneumatic components of the catapult to control the instantaneous release of gas from a low-pressure storage chamber, creating a high-pressure airflow within the launch tube. This allows the drone or loitering munition to reach the required exit velocity, enabling its launch. Existing pneumatic catapults are typically single-tube launchers, lacking continuous launch capability; while cluster pneumatic catapults often have complex pneumatic systems, compromising stability and reliability, and failing to meet the demands of continuous, rapid launch from the launch tube. Summary of the Invention

The first gas storage tank is a frame structure that matches the arrangement of the launch tubes and is fixedly mounted on the base frame. The first gas storage tank is provided with multiple gas outlets, and each gas outlet is provided with a launch valve. The launch valves are located at positions corresponding to each launch tube and are connected to the corresponding launch tube. The launch valves are configured to control the first gas storage tank to provide the gas required for pneumatic ejection to the corresponding launch tube.

[0005] In some embodiments, the cluster frame includes a front panel and a rear panel. The front panel is provided with a plurality of front mounting holes, and the rear panel is provided with a plurality of rear mounting holes. The two ends of the launch tube are respectively disposed in the front mounting holes and the rear mounting holes, and the launch tube is fixedly disposed on the cluster frame. The launch tube is provided with a front shoulder and a rear shoulder. The radial dimension of the front shoulder is larger than the diameter of the front mounting hole, and the radial dimension of the rear shoulder is smaller than the diameter of the rear mounting hole, so that the launch tube can pass through the front mounting hole and the rear mounting hole in sequence, and the movement of the launch tube toward the rear panel is limited by the cooperation between the front panel and the front shoulder. A limiting structure is provided between the rear axle shoulder and the rear panel, which is used to limit the movement of the launch tube toward the front panel.

[0006] In some embodiments, when the front shoulder forms a positioning fit on the front panel, an installation gap is formed between the rear shoulder and the rear panel. The limiting structure includes a plurality of limiting plates that can be fitted into the installation gap, and the limiting plates are fixedly connected to the rear panel.

[0007] In some embodiments, the front axle shoulder includes a limiting portion and a supporting portion, wherein the radial dimension of the limiting portion is larger than the diameter of the front mounting hole, and the supporting portion mates with the front mounting hole; The limiting plate is an arc-shaped plate that cooperates with the launch tube.

[0008] In some embodiments, a rotation limiting structure is provided between the launch tube and the front panel and the rear panel to restrict the rotation of the launch tube.

[0009] In some embodiments, the rotation limiting structure includes one or more limiting protrusions disposed on the launch tube and a limiting notch disposed on the limiting plate that cooperates with the limiting protrusions.

[0010] In some embodiments, the launch tube is provided with an air inlet connector, and the launch valve is connected to the air inlet connector via a quick-connect fitting.

[0011] In some embodiments, the first gas storage tank includes a plurality of vertically arranged gas storage tubes and a flow horizontal tube for connecting each gas storage tube, and the launching valve is arranged on one or both sides of the gas storage tube along the longitudinal direction of the gas storage tube.

[0012] In some embodiments, the intermediate gas storage tube is connected at one end to the flow horizontal tube via a transition gas storage tube, and the transition gas storage tube and the flow horizontal tube are connected at multiple locations.

[0013] On the other hand, the present invention also provides a method for assembling a pneumatic catapult device, comprising the following steps: S01. Securely install the cluster frame and the first gas storage tank onto the base frame; S02. Pass the rear end of the launch tube through the front mounting hole and the rear mounting hole in sequence, and connect it to the launch valve until a positioning fit is formed between the front axle shoulder and the front panel. S03. Insert a limiting plate into the installation gap between the rear axle shoulder and the rear panel, and fix the limiting plate to the rear panel. S04. Repeat steps S02 and S03 to complete the installation of all launch tubes in sequence.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0028] Reference Figure 1 , Figure 2 and Figure 7 The pneumatic catapult device in this embodiment includes: Base frame 400; The launch assembly 100 includes a cluster frame 12 and a plurality of launch tubes 11 disposed on the cluster frame. The launch tubes 11 are arranged in an array on the cluster frame 12, and the cluster frame 12 is disposed on the base frame 400. The first gas system 200 includes a first gas storage tank 21 disposed at one end of the cluster frame 12. The first gas storage tank 21 is a frame structure that matches the arrangement of the launch tubes and is fixedly disposed on the base frame 400. The first gas storage tank 21 is provided with multiple gas outlets 22, and each gas outlet 22 is provided with a launch valve 23. The launch valve 23 is located at a position corresponding to each launch tube 11 and is connected to the corresponding launch tube 11. The launch valve 23 is configured to control the first gas storage tank 21 to provide the gas required for pneumatic ejection to the first launch tube.

[0029] This pneumatic catapult adopts a cluster structure, with the launch assembly and first air path system mounted on the base frame. Multiple launch tubes are fixedly installed on the cluster frame to form an array or other structural arrangement of multi-tube launch structures. At the same time, launch valves are set on the first air tank to match the location of the launch tubes. Each launch tube is connected to the first air tank through each launch valve. By controlling the launch valves, the first air tank can be controlled to supply the gas required for pneumatic catapult launch to each launch tube, thereby realizing the pneumatic catapult launch of the aircraft.

[0030] The device adopts a structure in which the launching components and the first gas storage tank are combined to form an integral structure, which not only facilitates the stable connection and installation between each launching tube and the first gas storage tank, but also facilitates the rapid installation of the device on the transport vehicle.

[0031] The first gas tank 21, as a gas supply system that provides gas to the launch tube, is designed as a frame structure that matches the layout of the launch tube. This allows the launch tube and the first gas tank to be directly connected via a launch valve. This facilitates a stable connection between the launch tube and the first gas tank, simplifies the connection, reduces unnecessary gas paths, ensures the stability of the pneumatic launch, and reduces the failure rate of the device.

[0032] Here, the first air path system 200 provides the gas required for launch to each launch tube during pneumatic catapult launch. In actual operation, the first air path system can be connected to other air sources or air path systems. When the air pressure in the first air path system cannot meet the launch requirements, the first air path system can be quickly charged by another air source or air path system, thereby enabling continuous and rapid launch of this cluster-structure pneumatic catapult device.

[0033] Specifically, refer to Figure 7 The first gas storage tank 21 includes multiple vertically arranged gas storage tubes 211 and a transverse flow pipe 212 for connecting each gas storage tube. Launch valves are located on one or both sides of the gas storage tubes along their longitudinal direction, for connecting to one or two rows of launch tubes arranged in a row (here, a launch tube row refers to multiple launch tubes arranged in a row). This structural design of the first gas storage tank satisfies the overall spatial layout requirements of the system, reduces the system size, facilitates the connection between the first gas storage tank and each launch tube, and also meets the gas capacity requirements for launch tube launch under low-pressure conditions, providing sufficient gas for the launch tube launch operation.

[0034] like Figure 2As shown, taking a pneumatic catapult assembly arranged in 5 columns as an example, the corresponding first gas storage tank 21 includes three gas storage tubes 211. The three gas storage tubes 211 are connected to two flow horizontal pipes 212 at both ends, forming a connected closed container. The first gas storage tank 21 is located at one end of the pneumatic catapult assembly 100, with two gas storage tubes 211 located between two columns of launch tubes. Launch valves 23 are respectively installed on both sides of these two gas storage tubes 211. The launch valves 23 on both sides of the gas storage tubes are connected to the launch tubes 11 in the launch tube columns located on both sides of the gas storage tubes, so as to optimize the overall layout of the first gas path system in the system and reduce the overall size of the system.

[0035] In the first gas storage tank 21, the gas storage tube 211 located in the middle is connected at one end to the flow horizontal tube 212 via a transition gas storage tube 213, wherein the transition gas storage tube 213 and the flow horizontal tube 212 are connected at multiple locations. At this time, when the first gas storage tank is filled with gas, it can achieve uniform and rapid filling of all locations within the first gas storage tank, while ensuring the consistency of gas pressure at all locations within the first gas storage tank, and further increasing the capacity of the first gas storage tank.

[0036] In the first gas storage tank 21, when two rows of launching valves are installed on both sides of the gas storage tube, a supplementary gas storage pipe 214 is installed on the gas storage tube 211, and the supplementary gas storage pipe 214 is connected to the gas storage tube 211 at multiple locations. While increasing the capacity of the first gas storage tank, it can realize rapid gas supply to the corresponding launching tube at that location.

[0037] As a gas source or gas path system that can serve as the gas source for the first gas path system, a second gas path system can be used here, as shown in the reference. Figure 8 and Figure 9 The second air path system is connected to the first air path system and is used to supply air to the first air path system. The second air path system is used to supply air to the first air path system, so that the first air path system can provide the gas and pressure required for pneumatic ejection of one launch tube. By supplying air to the launch tube through the first air path system, the gas required for pneumatic ejection of the launch tube is provided, and the launch operation of the launch tube is completed. In the whole process, when one launch tube is launched, the second air path system quickly replenishes the first air path system for the pneumatic ejection operation of another launch tube, and the launch operation of all UAVs in the launch tubes is completed in sequence.

[0038] Because the gas pressure in the second gas path system is greater than that in the first gas path system, it enables rapid gas replenishment to the first gas path system and rapid continuous launch of the launch tubes. This effectively solves the problems of slow gas replenishment and inability to meet the requirements of rapid continuous launch in existing cluster-type pneumatic catapult systems. Furthermore, by setting up the first gas path system as an intermediate transition, the entire gas path system structure is simplified and easy to control. Moreover, the gas pressure is constant when the first gas path system supplies gas to each launch tube, making the gas supply control of the launch tubes during continuous launch simpler and providing better safety and reliability.

[0039] The second gas system includes a second gas storage tank 31 and a gas circuit unit. The second gas storage tank is connected to the first gas storage tank through the gas circuit unit to supply gas to the first gas storage tank.

[0040] Specifically, such as Figure 8 As shown, the gas circuit unit includes a first pipeline 32 and a second pipeline 33. The inlet end of the first pipeline 32 is connected to the second gas storage tank 31, and the outlet end of the first pipeline 32 is connected to the first gas storage tank 21. A pressure reducing valve 34 is provided on the first pipeline 32 to reduce the pressure of the high-pressure gas in the second gas storage tank 31 and then input it into the first gas storage tank 21 to realize a rapid gas replenishment operation from high pressure to low pressure. The second pipeline 33 is connected to the first pipeline 32 between its inlet end and the pressure reducing valve. The other end of the second pipeline 33 is connected to the pressure reducing valve 34. A pilot valve 35 is provided on the second pipeline 33.

[0041] When the pressure in the first gas tank is lower than the set value, the pilot valve controls the pressure reducing valve to open, and the high-pressure gas in the second gas tank is reduced in pressure and then filled into the first gas tank; when the pressure in the first gas tank reaches the set value, the pilot valve controls the pressure reducing valve to close, and stops the gas supply to the first gas tank.

[0042] Here, a pilot valve is used to achieve mechanical on / off control of the pressure reducing valve, which enables rapid gas replenishment from high pressure to low pressure in the gas circuit unit. The replenishment time is short, the control is stable and reliable, and the cost is low. It can also ensure the stability of the gas pressure value when filling the first gas storage tank.

[0043] An overflow valve can be installed on the pressure reducing valve. When the gas is overcharged, the overflow valve will automatically overflow to protect the gas circuit unit.

[0044] In order to quickly fill the first gas tank, multiple air inlets 215 can be provided on the first gas tank 21, and multiple branch pipes 321 can be connected to the air outlet of the first pipeline 32. The multiple branch pipes 321 are respectively connected to the air inlets on the first gas tank, and the first gas tank can be quickly replenished with gas from the multiple air inlets.

[0045] A gas supply pipe 36 is installed on the first pipeline 32 near the inlet end, through which the second gas storage tank can be filled. Ball valves 37 are installed on the gas supply pipe 36 and on both sides of the first pipeline 32, for on / off control of the gas system under different operating conditions. For example, when filling the second gas storage tank, the ball valve on the first pipeline near the outlet end is closed, and the other two ball valves are opened, allowing the second gas storage tank to be filled through the base station's gas source. When replenishing the first gas storage tank, the ball valve on the gas supply pipe is closed, and the other two ball valves are opened.

[0046] A safety valve 38 is installed on the first pipeline 32. The safety valve is used to ensure the safety of the base station gas source during the process of filling the second gas storage tank.

[0047] Since each launching tube in this device is rigidly connected to the first gas storage tank, achieving stable fixation of the launching tubes and stable connection between the launching tubes and each launching valve requires high precision in the position of the launching tubes on the cluster frame, the position of the launching valves on the first gas storage tank, and the relative positional precision between each launching tube and the launching valve. This places high demands on the machining precision of the cluster frame and the first gas storage tank. Furthermore, it also places high demands on the installation precision of the launching tubes on the cluster frame, the installation precision of the cluster frame on the base, and the installation precision of the first gas storage tank on the base, posing many challenges to the machining and assembly of the device.

[0048] To address the aforementioned technical problems, in one embodiment, as follows: Figure 3 The cluster frame 12 includes a front panel 121 and a rear panel 122. The front panel 121 is provided with a plurality of front mounting holes 123, and the rear panel 122 is provided with a plurality of rear mounting holes 124. The two ends of the launch tube 11 are respectively placed in the front mounting holes 123 and the rear mounting holes 124, and the launch tube 11 is fixedly mounted on the cluster frame 12. like Figure 5 The launch tube 11 is provided with a front axle shoulder 112 and a rear axle shoulder 113. The radial dimension of the front axle shoulder 112 is larger than the diameter of the front mounting hole 123, and the radial dimension of the rear axle shoulder 113 is smaller than the diameter of the rear mounting hole 124, so that the launch tube can pass through the front mounting hole and the rear mounting hole in sequence, and the movement of the launch tube toward the rear panel is limited by the cooperation between the front panel and the front axle shoulder. A limiting structure is provided between the rear axle shoulder and the rear panel. The limiting structure is used to limit the movement of the launch tube toward the front panel.

[0049] By designing the cluster frame structure and the launch tube structure, the front shoulder of the launch tube is positioned on the front panel during installation, thus limiting the front end of the launch tube on the cluster frame. At this time, due to the large diameter of the rear mounting hole, a certain amount of adjustment space is provided for the connection and installation between the launch tube and the launch valve. The launch tube can then be easily connected to the launch valve. Then, a limiting structure is installed between the rear shoulder and the rear panel to limit the rear end of the launch tube on the cluster frame. This allows the launch tube to be fixedly installed on the cluster frame while connecting and assembling the launch valve.

[0050] This structural form and installation method undoubtedly greatly reduces the requirements for the machining accuracy of the cluster frame and the first gas storage tank, as well as the installation accuracy of the launch tube on the cluster frame, the installation accuracy of the launch valve on the first gas storage tank, and the assembly accuracy of the cluster frame and the first gas storage tank on the base frame. This facilitates the machining and assembly of the device and effectively solves the aforementioned problems.

[0051] Specifically, when the front shoulder 112 forms a positioning fit on the front panel 121, an installation gap is formed between the rear shoulder 113 and the rear panel 122. The limiting structure includes multiple limiting plates 15 that can be inserted into the installation gap, and the limiting plates 15 are fixedly connected to the rear panel 122. After the launch tube is assembled and connected to the launch valve, each limiting plate 15 is snapped into the space between the rear shoulder and the rear panel, and then the limiting plates 15 are fixed to the rear panel 122 with bolts. At this time, the movement of the launch tube towards the rear panel is limited by the fit between the limiting plates and the rear shoulder. Here, the plates are set as arc-shaped plate structures that fit with the launch tube, which not only limit the movement of the launch tube, but also fix the rear end of the launch tube to the rear panel.

[0052] The front axle shoulder 112 includes a limiting part 1121 and a supporting part 1122. The radial dimension of the limiting part 1121 is larger than the diameter of the front mounting hole 123. The supporting part 1122 cooperates with the front mounting hole 123 to stably fix the front end of the launch tube through the front panel.

[0053] In one embodiment, a rotation limiting structure is provided between the launch tube 11 and the front panel 121 and the rear panel 122 to restrict the rotation of the launch tube. By providing the rotation limiting structure, the launch tube is more stably mounted on the cluster frame. Specifically, as shown... Figure 4 and Figure 5 The rotation limiting structure includes one or more limiting protrusions 114 disposed on the launch tube 11 and limiting notches 151 disposed on the limiting plate 15 that cooperate with the limiting protrusions. For example... Figure 7As shown, two limiting protrusions 114 are provided at the rear axle shoulder 113 position, and two limiting plates 15 are respectively provided with limiting notches 151. When the limiting plates are snapped between the rear axle shoulder and the rear panel, the limiting notches and the limiting protrusions are respectively connected to each other. In this way, when the limiting plates are fixedly installed on the rear panel, the rotation of the launch tube on the cluster frame can be limited, and the launch tube can be stably installed on the cluster frame.

[0054] In one embodiment, the launching tube 11 is provided with an air inlet connector 111, and the air outlet of the launching valve 23 is connected to the air inlet connector 111 via a quick-connect connector 14. Figure 6 As shown, one end of the quick-connect fitting 14 is inserted into the outlet of the launch valve 23, and the other end of the quick-connect fitting 14 is inserted into the inlet fitting 111, realizing a quick connection between the launch tube and the launch valve. During installation, after the launch valve is installed on the first gas tank, the quick-connect fitting is fixedly connected to the outlet of the launch valve, and sealant is applied to the installation position; a Y-type sealing ring is installed on the other end of the fitting, and the inlet fitting of the launch tube is inserted into the fitting structure, realizing a quick and reliable connection and installation between the launch tube and the launch valve, reducing the difficulty of system cluster assembly.

[0055] The launch tube used for pneumatic catapults typically includes a tube body and a piston installed inside the tube body. The air inlet is located at the bottom of the tube body. When high-pressure gas is introduced into the launch tube through the air inlet, the instantaneous high-pressure gas generates a pushing force on the piston, which in turn pushes the piston and the aircraft installed inside the tube body to move, thereby achieving the catapult operation of the aircraft.

[0056] On the other hand, the present invention also relates to an assembly method for the pneumatic catapult device in the above embodiments. As we know from the foregoing description, although this clustered pneumatic catapult device can solve the problem of continuous and rapid launch of each launch tube, the connection method between each launch tube and the first gas storage tank brings great difficulties to the processing and assembly of the device. Based on the structural characteristics of the device of the present invention, the assembly method of the present invention can solve this problem well.

[0057] Specifically, the assembly method of the pneumatic catapult includes the following steps: S01. Fix the cluster frame 12 and the first gas storage tank 21 onto the base frame 400; S02. Pass the rear end of the launch tube 11 through the front mounting hole 123 and the rear mounting hole 124 in sequence, and connect the air inlet connector 111 of the launch tube to the launch valve 23 until a positioning fit is formed between the front axle shoulder and the front panel. The connection between the launch tube and the launch valve is made using the following method: The quick-connector 14 is inserted into the air outlet of each of the launch valves 23. When assembling the launch tube, the air inlet connector 111 of the launch tube is aligned with the quick-connector 14. Then, the launch tube is pushed so that the quick-connector 14 is inserted into the air inlet connector 111 of the launch tube, thereby achieving the connection between the launch tube 11 and the launch valve 23. S03. Insert a limiting plate 15 into the installation gap between the rear axle shoulder 113 and the rear panel 122, and fix the limiting plate 15 to the rear panel 122. The limiting plate supports and limits the rear end of the launch tube, thereby completing the fixed installation of the launch tube on the cluster frame. S04. Repeat steps S02 and S03 to complete the installation of all launch tubes in sequence.

[0058] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use. They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0059] Furthermore, the use of terms such as "horizontal" and "vertical" in the description of this invention does not imply that the components are required to be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0060] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
