Problems solved by technology
[0002] In recent years, the field of civilian UAV technology has developed rapidly, especially fixed-wing UAVs have obvious advantages compared with multi-rotor UAVs in terms of long range, long flight time in the air, and fast speed. The aircraft has strict requirements on the runway environment during take-off and landing, and also has high requirements on the pilot's operating level
Due to the high requirements on the openness and length of the runway for fixed-wing UAVs, most urban areas cannot meet the normal take-off and landing of fixed-wing UAVs. The aircraft made a short and safe landing on the designated runway

Embodiment Construction
[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0013] As shown in the attached figure, for the landing deceleration and damping device of the fixed-wing UAV, the left retractor (3) and the right retractor (4) pass through the four positioning holes of the fixing seat (8) respectively, and are fixed on the specified position of the UAV. on the landing runway.
[0014] As shown in the drawings, the coil springs (7) inside the left retractor (3) and the right retractor (4) are retracted when they are not stressed, and the free ends of the coil springs (7) are hooked to the arresting cable (2 ), the fixed end is tightened to the center of the fixed seat (8) through the bolt (5).
[0015] As shown in the attached figure, when the UAV lands from the scheduled route, the flight controller lowers the landing hook (1) at the tail of the aircraft at this time, and when the aircraft slides ...

Because of multiple factors that the sliding distance is long, and a landing field is highly required in the fixed wing unmanned aerial vehicle landing process, an unmanned aerial vehicle is very hard to land safely within a short distance in an appointed area. An unmanned aerial vehicle tail towing hook is innovatively used in a fixed wing unmanned aerial vehicle landing slow-down damping device, damping ropes can be hooked when the unmanned aerial vehicle is landed, and by virtue of the damping functions of reels, the inertia force of the unmanned aerial vehicle can be rapidly attenuated. The fixed wing unmanned aerial vehicle landing slow-down damping device is characterized in that the damping ropes (2) are hung on free ends of inner reels of two coilers respectively; fixed ends of the reels are fastened on a fixing base through bolts; mounting holes of the damping ropes (2) of protecting hoods on the two coilers are mounted in the same direction. When the unmanned aerial vehicle slides and the towing hook (1) is hung with the damping ropes (2), the reels play a role of damping, and thus short-distance landing of the fixed wing unmanned aerial vehicle can be achieved.
Description
technical field [0001] The invention relates to the technical field of civil unmanned aerial vehicle equipment, in particular to a landing deceleration and damping device for a fixed-wing unmanned aerial vehicle. Background technique [0002] In recent years, the field of civilian UAV technology has developed rapidly, especially fixed-wing UAVs have obvious advantages compared with multi-rotor UAVs in terms of long range, long flight time in the air, and fast speed. The aircraft has strict requirements on the runway environment during take-off and landing, and also has high requirements on the pilot's operating level. Due to the high requirements on the openness and length of the runway for fixed-wing UAVs, most urban areas cannot meet the normal take-off and landing of fixed-wing UAVs. The aircraft made a short and safe landing on the designated runway. [0003] In view of the above problems, the landing deceleration and damping device of the fixed-wing unmanned aerial ve...
