Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a folding-wing loitering drone mounting and deployment device and deployment method. Background Technology

[0002] A folding-wing loitering drone is an unmanned aerial vehicle (UAV) whose wings can be folded and stowed. It is typically launched from a ground-based launch tube, but can also be deployed remotely from transport aircraft, large UAVs, or other platforms. After launch from the launch tube or deployment from the platform, the folding-wing loitering drone's wings unfold and lock, allowing it to fly normally. It typically carries a reconnaissance pod for long-range target reconnaissance. When carrying a warhead or other destructive payload, it can launch real-time suicide attacks on detected targets. It can also carry various payloads such as jammers, decoys, and magnetic detectors, depending on mission requirements.

[0003] When a folding-wing loitering pod is deployed via a transport aircraft, large drone, or other platform, all wings must be folded and stowed before deployment. After deployment, the loitering pod must first be safely separated from the transport platform. Once the safe separation is complete, the wing constraints of the loitering pod must be released and the wing surfaces of the loitering pod must be deployed and locked.

[0004] Existing loitering rovers' mounting and deployment devices have the following drawbacks:

[0005] 1. The loitering pod cannot guarantee that a safe distance has been achieved between it and the launch platform when the restraints on the folding wings are released and the folding wings are deployed. Aerodynamic interference may occur between the loitering pod and the launch platform during the deployment process, resulting in insufficient deployment safety.

[0006] 2. The launch and deployment devices of loitering drones generally use pyrotechnics for activation, which is relatively unsafe and cannot be recycled and reused.

[0007] This payload delivery device controls the separation distance between the folding-wing loitering pod and the carrier platform. Once the loitering pod reaches a safe relative distance from the platform, the restraint on the folding wings is released, and the folding wings unfold, initiating loitering flight. This device reduces aerodynamic interference between the loitering pod and the carrier platform during delivery, significantly improving delivery safety. Furthermore, this device is free of pyrotechnics and deceleration parachutes, featuring a simple, safe, reliable, and low-cost mechanism that can be reused multiple times. Its operational process is also described. Therefore, there is a need to develop a folding-wing loitering pod payload delivery device and method to address the aforementioned issues. Summary of the Invention

[0008] The purpose of this invention is to design a folding-wing loitering vehicle mounting and deployment device and deployment method to solve the above-mentioned problems.

[0009] The present invention achieves the above objectives through the following technical solutions:

[0010] A folding-wing loitering pod mounting and deployment device includes:

[0011] The delivery tube is formed into a hollow cylindrical structure, including a hollow semi-cylindrical body and two 1 / 4 hollow cylindrical hatches; the outer side of the two hatches is connected to the lower outer sides of the body through multiple torsion spring hinges; the upper end of the delivery tube is connected to the transport platform through a connecting structure.

[0012] A hatch control servo motor is used to control the opening and closing of the two hatches; the hatch control servo motor is used to connect the lower ends of the two hatches.

[0013] Control device; The control device includes a traction rope and at least two fixed ropes, the upper ends of which are connected to the main body of the control device.

[0014] Separation ring; the lower part of the separation ring is placed on the inner side of the lower end of the two hatches; the separation ring includes two half rings and a pin locking mechanism; the folding wing loitering aircraft is placed between the two half rings forming a ring; the upper ends of the two half rings are connected by the pin locking mechanism, the upper end of the pin of the pin locking mechanism is connected to the lower end of the towing rope, and the lower ends of at least two fixing ropes are respectively connected to the two half rings.

[0015] Specifically, the folding-wing loitering pod's mounting and deployment device also includes a pylon, with multiple attachment points on the upper surface of the tube body. The lower end of the pylon is connected to the multiple attachment points, and the upper end of the pylon is connected to the transport platform.

[0016] Preferably, both the front and rear ends of the dispensing tube are hemispherical.

[0017] Preferably, the folding-wing loitering vehicle mounting and launching device further includes two load-bearing frames. The two load-bearing frames are arranged on the inner side of the launching tube along the length direction of the launching tube. The load-bearing frames include a semi-circular ring frame and a quarter-circular ring frame. The semi-circular ring frame is fixedly installed on the inner side of the tube body, and the quarter-circular ring frame is fixedly installed on the inner side of the hatch. The two ends of the semi-circular ring frame are respectively hinged to one end of the two quarter-circular ring frames. The front and rear limiting modules on the folding-wing loitering vehicle are placed between the two load-bearing frames.

[0018] Preferably, buffer pads for axial limiting and buffering of the loitering device are provided on the inner sides of both ends of the cylinder.

[0019] Furthermore, a guide frame for vertical movement of the folding-wing loitering device is provided on the inner side of the tube, with the two sides of the folding-wing loitering device positioned between the guide frame.

[0020] Furthermore, the main body of the control device includes a rope winder, and the upper ends of the traction rope and the fixing rope are connected to the rope winder.

[0021] A method for deploying a folding-wing loitering rovers' mounting and deployment device includes the following steps:

[0022] S1. Set the release length of the traction rope through the control device;

[0023] S2. The hatch control servo unlocks the connection at the lower end of the two hatches, and the two hatches open to the sides under the action of the torsion spring hinges.

[0024] S3. The separation ring carrying the folding-wing loitering aircraft moves downward along the guide frame under its own gravity and detaches from the release tube;

[0025] S4. When the traction rope is taut, the traction rope pulls out the pin in the pin locking mechanism, and the two half rings of the separation ring open under the action of the fixing rope, releasing the folding wing loitering drone.

[0026] S5. Using the rope reel of the control device, wind up the traction rope and the fixing rope to pull the separation ring back into the delivery cylinder and close the hatch.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. By controlling the settings of the traction rope and the fixing rope, the safe separation distance between the loitering vehicle and the carrier platform can be controlled. When the safe separation distance is reached, the separation ring is released from the constraint of the missile wings, which reduces the aerodynamic interference between the loitering vehicle and the carrier platform during deployment and improves deployment safety.

[0029] 2. The release tube uses a hatch control servo to unlock the hatch, ensuring reliable locking and synchronous unlocking of the hatch; and multiple sets of torsion spring hinges provide elasticity to ensure quick and reliable opening of the hatch after unlocking.

[0030] 3. The load-bearing frame inside the release tube can not only bear the main weight of the loitering pod, but also limit the folding-wing loitering pod in the lateral and longitudinal directions. The buffer pads set at the head and tail of the release tube can limit and buffer the folding-wing loitering pod in the axial direction.

[0031] 4. A guide frame is installed inside the release tube to guide the loitering drone during detachment and prevent the wings from rotating left or right, which would interfere with the release and separation process.

[0032] 5. After the loitering vehicle is deployed and separated, the separation ring is recovered, which reduces the aerodynamic drag of the carrier platform, improves safety, and the deployment device can be reused multiple times.

[0033] 6. The entire mounting and launching device has no pyrotechnics or deceleration parachutes, and the mechanism is simple, safe, reliable, and low in cost. Attached Figure Description

[0045] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] like Figure 1-4 As shown, a folding-wing loitering pod mounting and deployment device includes:

[0047] The delivery cylinder 1 is formed into a hollow cylindrical structure, including a hollow semi-cylindrical body and two 1 / 4 hollow cylindrical hatches 11; the outer side of the two hatches 11 is connected to the lower outer sides of the cylinder body through multiple torsion spring hinges 8 (the elasticity provided by the torsion spring hinges 8 ensures that the two hatches 11 can be opened quickly and reliably); the upper end of the delivery cylinder 1 is connected to the transport platform through a connecting structure.

[0048] A door control servo motor 10 is used to control the opening and closing of the two hatches 11; the door control servo motor 10 is used to connect to the lower end of the two hatches 11.

[0049] Control device 6; The control device 6 includes a traction rope 55 and two fixing ropes 54, the upper ends of the traction rope 55 and the fixing ropes 54 are connected to the main body of the control device 6.

[0050] Separation ring 5; the lower part of separation ring 5 is placed on the inner side of the lower end of the two hatches 11; separation ring 5 includes two half rings 51 and a pin locking mechanism 52; folding wing loitering 2 is placed between the two half rings 51 forming a ring; the upper ends of the two half rings 51 are connected by the pin locking mechanism 52, the upper end of the pin 53 of the pin locking mechanism 52 is connected to the lower end of the towing rope 55, and the lower ends of at least two fixing ropes 54 are respectively connected to the two half rings 51.

[0051] In this embodiment, the folding wings of the loitering drone are locked by the separation ring 5. After the separation ring 5 is unlocked, the left and right halves of the ring 51 automatically pop open to release the lock on the folding wings and separate from them. The structure is simple and reliable.

[0052] like Figure 1-3 As shown, the folding-wing loitering drone 2 mounting and deployment device also includes a pylon 12. Four attachment points 4 are provided on the upper surface of the tube body. The lower end of the pylon 12 is connected to the four attachment points 4, and the upper end of the pylon 12 is connected to the transport platform.

[0053] like Figure 1-3 As shown, both the front and rear ends of the dispensing cylinder 1 are hemispherical.

[0054] like Figure 1 and 3 As shown, the folding-wing loitering pod 2's launch device also includes two load-bearing frames 3. These frames 3 are arranged along the length of the launch tube 1 on its inner side. Each load-bearing frame 3 includes a semi-circular ring frame and a quarter-circular ring frame. The semi-circular ring frame is fixedly installed on the inner side of the tube body, and the quarter-circular ring frame is fixedly installed on the inner side of the hatch 11. The two ends of the semi-circular ring frame are hinged to one end of each of the two quarter-circular ring frames. The front and rear limiting modules on the folding-wing loitering pod 2 are positioned between the two load-bearing frames 3. The load-bearing frames 3 serve as connectors within the launch tube 1, linking the upper and lower tube bodies, and are the main load-bearing components within the launch tube 1. The load-bearing frames 3 also provide lateral and longitudinal limiting for the folding-wing loitering pod 2.

[0055] like Figure 1 As shown, buffer pads 7 are provided on the inner sides of both ends of the cylinder for axial limiting and buffering of the loitering vehicle.

[0056] like Figure 1 and 3 As shown, a guide frame 9 for vertical movement of the folding-wing loitering 2 is provided on the inner side of the cylinder, and the two sides of the folding-wing loitering 2 are placed between the guide frames 9.

[0057] In some embodiments, the control device 6 includes a rope reel, with the upper ends of the traction rope 55 and the fixing rope 54 connected to the rope reel. The control device 6 controls the separation distance between the loitering drone and the carrier platform by controlling the length of the traction rope 55, ensuring a relatively safe distance. The operation involves retracting and extending the rope reel. After the folding-wing loitering drone 2 is released, the traction rope 55 and the fixing rope 54 can be retracted by the rope reel, thereby pulling the separation ring 5 back into the delivery cylinder 1. This reduces the aerodynamic drag of the carrier platform, improves safety, and allows the delivery device to be reused multiple times.

[0058] In some embodiments, the body of the delivery tube 1 is made of glass fiber material with wave-transmitting function, which is lightweight and facilitates satellite positioning and wireless communication with the ground for the folding wing loitering drone 2 before delivery.

[0059] A method for deploying a folding-wing loitering rovers' mounting and deployment device includes the following steps:

[0060] S1. Set the release length of the traction rope 55 through the control device 6;

[0061] S2. The hatch control servo 10 unlocks the connection at the lower end of the two hatches 11, and the two hatches 11 open to the sides under the action of the torsion spring hinge 8.

[0062] S3. The separation ring 5 carrying the folding-wing loitering 2 moves downward along the guide frame 9 under its own gravity and separates from the release tube 1.

[0063] S4. When the traction rope 55 is taut, the traction rope 55 pulls out the pin 53 in the pin locking mechanism 52, and the two half rings 51 of the separation ring 5 open under the action of the fixing rope 54, releasing the folding wing loitering device 2; the folding wing is unlocked and unfolded, and the loitering device enters the flight state.

[0064] S5. By using the rope reel of the control device 6 to reel in the traction rope 55 and the fixing rope 54, the separation ring 5 is pulled back into the delivery cylinder 1, and the hatch is closed.

[0065] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
