A method and system for continuous recovery of unmanned aerial vehicles that collide with nets in the air

Abstract

The invention discloses a continuous recovery system for an aerial net-impacting unmanned aerial vehicle, which comprises a carrier aircraft, a tow cable, a lifting body-shaped drag cabin, an aviation winch, a visual navigation system, and a continuous net-impact recovery device. When recovering, the carrier aircraft releases the tow cable through the aviation winch, and releases the towing cabin in the shape of the lift body. The UAV flies in from the tail of the towing cabin under the guidance of the visual navigation system. Slow down on the U-shaped slide rail conveying device and slide into the conveyor belt device for transportation and storage; after all the drones are recovered, the aviation winch retracts the towline, and puts the towing cabin and the drone into the carrier aircraft to complete the air-based recovery. The invention uses the towing cabin system to place the recovery device outside the interference flow field of the carrier aircraft, which can avoid the influence of the carrier aircraft on the recovery process, has a high recovery success rate, high safety of the carrier aircraft, and can safely and continuously recover multiple aircraft in the air drone.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a method and system for continuous recovery of unmanned aerial vehicles that collide with nets in the air. Background technique [0002] In recent years, as a brand-new and subversive ideal combat mode, swarm drone 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 drones. , to 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...

AI Technical Summary

Problems solved by technology

We cannot simply transport the land-based net impact recovery device directly into the air for drone recovery, they cannot meet the requirements of recovering multiple swarm drones at one time

The existing space-based towed net recovery device, such as the patent CN 107792381A, adopts the single-net multiple recovery method. Although this method can realize the simultaneous recovery of multiple drones, it also has unavoidable design defects: First of all, to ensure that small UAVs can successfully hit the recycling net, the net surface needs a certain density, and the large-area recycling net being dragged in the air means that the recycling net cannot be too dense, otherwise complex stabilizing devices are required to keep the net The vertical state of the surface; secondly, multiple drones may collide with the same small area of ​​the recovery net, which is difficult to ensure that the drone body will not be damaged, resulting in a reduction in the success rate of the entire recovery
