Abstract

Disclosed are an unmanned aerial vehicle air-based retraction device and method based on an aviation towed stable target system. The device is composed of a retractable mounting bracket, an aviation winch, a towing rope, a stable target and an arresting cable retraction structure. The towing rope is released through the aviation winch, thus the stable target is released, an unmanned aerial vehicleapproaches from the rear of the stable target under the guidance of a guidance system, a retraction hook on the back of the unmanned aerial vehicle is impacted, abutted and locked with an arresting cable device below the stable target, the unmanned aerial vehicle is retracted into a mother ship along with the aviation winch retracting the towing rope tow target, then workers unload the unmanned aerial vehicle from the arresting cable device, and thus air-based retraction is realized. According to the method, the stable target and the small unmanned aerial vehicle are both away from the mothership, airflow disturbances are small, the safety of the mother ship is improved, and the mother ship has small disturbances to the unmanned aerial vehicle, so that the retraction accuracy rate is high.

Description

technical field

[0001] The invention discloses a UAV space-based recovery device and method based on an aviation towed stable target system, and belongs to the field of UAV 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 recovery technology of small UAVs h...
