An unmanned aerial vehicle air-based towed net type recovery device and method

Abstract

The invention discloses an unmanned aerial vehicle air-based towed net recovery device and method. The device includes a retractable mounting bracket, two aviation winches, two tow cables, a tow net, a net winding device and a tow net stabilization system. With the help of the towing target technology and the towing net stabilization system, the present invention releases the towing cable synchronously through two aviation winches during recovery, unfolds the towing net installed between the two towing cables, and drags the net under the action of the stabilizing towing target Keep a steady posture. When the UAV hits the net, the UAV is recovered with the tow net to realize space-based recovery. A certain number of UAVs can be recovered at the same time, which shortens the time spent by the UAV cluster in the recovery process, improves the recovery efficiency, and reduces the risk of damage to the UAV and the parent aircraft. The towing net has a large area and has low requirements on the accuracy of UAV recovery, which is easy to implement.

Description

technical field [0001] The invention includes a set of unmanned aerial vehicle space-based tow net recovery device and method based on a tow target system, and belongs to the field of unmanned aerial vehicle recovery of aviation aircraft technology. Background technique [0002] Since the 1930s, people have been yearning to realize the space-based launch and recovery of aircraft. This method of launch and recovery transports the sub-plane to the mission area through the mother plane with a large range and load, which can greatly increase the capacity of the sub-plane. The cruising radius gets rid of the limitation of the ground airport and increases the flexibility of the take-off and landing of the sub-machine. However, limited by technology, risk and cost, aircraft space-based launch and recovery technology has not been well developed. [0003] In recent years, with the development of UAV technology and the recent proposal of swarm UAV tactics, the space-based launch and ...

AI Technical Summary

Problems solved by technology

Although these methods can realize the simultaneous recovery of large batches of UAVs, their disadvantages are obvious: First, in order to avoid the turbulent flow near the parent aircraft, it is necessary to design a long mechanical mechanism so that the net is far away from the parent aircraft when it is opened. relatively far

The structure of the rolling net release device is simple, and there is no stabilizing device in the air after the net is released; secondly, large-scale recycling requires a larger area of ​​the blocking net, and a corresponding folding mechanism is required to meet the storage in the main machine in an idle state. structural complexity

Finally, the above-mentioned recycling methods of the prior art will cause relatively large damage to the structure of the UAV, which will lead to a reduction in the service life of the UAV.
