Description

Technical Field

[0001] The utility model belongs to the technical field of UAV recovery equipment, and particularly relates to a parachute cabin for folding-wing UAV parachute recovery. Background Technique

[0002] The initial wings of the folding-wing UAV are folded and placed in the launch tube. After the UAV is launched out of the tube, the wings are unfolded. Generally, a forward-pull or rear-push type power propeller is used. Therefore, in general research and test experiments, the folding-wing UAV generally uses parachute landing recovery to reduce losses. In view of this, a structural arrangement method of a parachute cabin that can be used for the landing recovery of folding-wing UAVs is designed;

[0003] For existing folding-wing UAVs, generally, the recovery parachute cabin is integrated with the airframe. In actual flight operations, after one flight mission is completed, the parachute needs to be folded. Especially for heavier UAVs, the parachute area will be correspondingly larger, and folding the parachute is more troublesome. In the case of a large number of flight missions, folding the parachute is time-consuming and laborious.

[0004] Therefore, the utility model designs a parachute cabin for folding-wing UAV parachute recovery to solve the technical problems existing in the prior art. Content of the Utility Model

Detailed Description of the Embodiments

[0024] Regarding the foregoing and other technical contents, features and effects of the present utility model, they will be clearly presented in the following detailed description in conjunction with the Figures 1-5 reference to the embodiments. The structural contents mentioned in the following embodiments are all with reference to the accompanying drawings of the specification.

[0025] Next, various exemplary embodiments of the present utility model will be described with reference to the drawings.

[0026] Embodiment 1, a parachute compartment 1 for folding-wing UAV parachute recovery, comprising a parachute compartment 1 and a parachute compartment cover 2, characterized in that:

[0027] The top of the described parachute compartment 1 is provided with a fixing block 3, and the bottom is hinged with a parachute compartment cover 2;

[0028] The fixing block 3 is threadedly connected with a pre-tightening screw 4. One end of the pre-tightening screw 4 is provided with a pre-tightening rope 5, and the pre-tightening rope 5 is matched with a release control block 6;

[0029] The release control block 6 is provided with a mounting groove 7 and a limiting groove 8, and a cutter 9 is arranged in the mounting groove 7;

[0030] The parachute compartment cover 2 is provided with a release rope 10 located in the limiting groove 8 and matched with the cutter 9;

[0031] The inside of the parachute compartment 1 is provided with a main parachute 11, and a pilot parachute 12 is arranged on the main parachute 11 close to the parachute compartment cover 2;

[0032] The parachute compartment 1 is provided with a limiting plate 13, and the parachute compartment cover 2 is provided with a limiting hook 14 rotatably connected with the limiting plate 13;

[0033] Both the parachute compartment 1 and the parachute compartment cover 2 are made of carbon fiber material;

[0034] The fixing block 3 is made of aluminum alloy material;

[0035] The parachute compartment 1 is made of metal parts, and the overall appearance is arranged as a cuboid;

[0036] The pre-tightening rope 5 is a Kevlar rope, and the release rope 10 is arranged as a nylon rope.

[0037] There are two metal blocks at the top of the parachute compartment for connecting with the folding-wing unmanned aerial vehicle. The fixing block is provided with pre-tightening holes to prevent the compartment cover from loosening;

[0038] The parachute compartment cover and the parachute compartment are both made of carbon fiber material, with light weight and high strength, and can be mass-produced. The metal block is made of aluminum alloy material, with light mass and convenient for machining and forming;

[0039] During use, the cutter 9 is controlled by a controller. Since the cutter 9 is arranged in the mounting groove 7 and the cutter 9 is provided with a wire threading hole, one end of the nylon rope is fixedly connected with the cover of the parachute compartment 1, and the other end passes through the limiting groove 8 and the wire threading hole to be connected with the cover of the parachute compartment 1. One end of the pre-tightening rope 5 is connected with the pre-tightening screw 4, and the other end passes through the release control block 6 to be connected with the pre-tightening screw 4;

[0040] By the action of the pre-tightening screw 4, the release control block 6 can be driven to move, so as to realize the tension of the pre-tightening rope 5, make the parachute compartment cover 2 fit tightly with the bottom of the parachute compartment 1, and avoid loosening;

[0041] The arrangement mode of this parachute bay 1 can make the assembly of the recovery parachute relatively independent. Following the requirements of design interchangeability, multiple recovery parachute modules can be assembled for the UAV as spares, enabling the UAV to increase the number of flight sorties in a short time and improving the test efficiency.

[0042] The structural arrangement scheme of the parachute and parachute bay 1 for the folding-wing UAV used for parachute recovery. The UAV needs to reserve an installation hatch for the parachute bay 1, and the parachute bay 1 needs to be embedded in the UAV. The parachute bay 1 cover faces downward on the surface of the UAV for convenient parachute opening.

[0043] This parachute bay 1 and the recovery parachute are separate modules. When loading the UAV, the UAV only needs to provide fixed hole positions and positions for fixing the parachute ropes. The parachute bay 1 is a metal part with an overall cuboid design and can accommodate a parachute with a large area.

[0044] The above content solves the technical problem of the existing folding-wing UAV. Generally, the recovery parachute bay 1 and the airframe are integrated. In actual flight operations, after one flight sortie, the parachute needs to be folded. Especially for heavier UAVs, the area of the parachute is correspondingly larger, and folding the parachute is more troublesome. In the case of more sortie requirements, folding the parachute is time-consuming and laborious.

[0045] The above description is only for explaining the present invention. It should be understood that the present invention is not limited to the above embodiments, and various equivalent forms conforming to the idea of the present invention are within the protection scope of the present invention.
