A UAV sliding track type air rapid recovery system

Abstract

The invention discloses an unmanned aerial vehicle slide rail type fast recovery system in the air, which is composed of a carrier aircraft, a tow cable, a flying wing-shaped towing cabin, an aviation winch and a slide rail capture and recovery device; during recovery, the tow cable is released through the aviation winch, Release the flying-wing-shaped towing cabin, and the UAV approaches the rear of the flying-wing-shaped towing cabin under the guidance of the guidance system, and uses the arresting hook on the back to collide with the catch hook at the rear of the flying-wing-shaped towing cabin and lock it , the UAV folds its wings and shuts down, moves along the slide rail into the interior of the flying wing-shaped tow cabin and fixes it, and at the same time, the next capture hook moves to the docking port through the conveying system and is in place; after all the UAVs to be recovered are recovered, the aviation winch The tow cable takes the flying wing-shaped towing cabin and the UAV into the carrier together to complete the aerial recovery. The invention can recover small unmanned aerial vehicles rapidly in multiple batches. During the recovery process, the flying wing-shaped towing cabin is far away from the carrier aircraft, and the disturbance of the flow field by the wake of the carrier aircraft is small, which improves the safety of the carrier aircraft and improves the accuracy of drone recovery. sex.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle sliding track type air rapid recovery system. Background technique [0002] In recent years, as a brand-new and subversive ideal combat mode, swarm UAV tactics have attracted the attention of various countries. It takes intelligent cluster technology as the core, and connects the weak combat capabilities of single aircraft through the collaborative network of UAVs. Build a new type of combat system with low cost, strong anti-strike capability, and diversified combat modes. [0003] The core advantages of UAV swarms are: low stand-alone cost, large number of swarms, and high swarm intelligence, which means that swarm drones are often designed as disposable consumables. However, even at a low cost, they still contain some unwanted The key core technology mastered by the enemy, one solution is to destroy the drone or damage the electronic...

AI Technical Summary

Problems solved by technology

[0005] Due to limiting factors such as size and weight, we cannot simply transport land-based and sea-based UAV recovery devices directly into the air for UAV recovery. They cannot meet the requirements of recovering multiple swarm drones at one time.

Existing aerial recovery devices, such as patent CN 107697303A, adopt the method of single-drag and stable target single-frame recovery. Although this method can realize the aerial recovery of a single UAV, there are unavoidable design defects: first , to ensure the successful docking of small UAVs, it is necessary to ensure the stability of the towed stable target. For uncontrolled targets, the conditions are harsh and it is difficult to guarantee successful docking

Secondly, it can only be recovered by a single drone, and the recovery efficiency is seriously reduced due to repeated retraction and release of the tow cable, which cannot meet the needs of rapid recovery of multiple small drones

Thirdly, the flight speed of the transport aircraft is faster than that of the small drones. Reducing the speed of the transport aircraft poses a risk to the safety of the transport aircraft. It is also difficult to ensure the accuracy of the docking when the drone is flying at full speed, and it is difficult to guarantee the successful docking
