A system and method for active and rapid recovery of fixed-wing unmanned aerial vehicles

Abstract

The invention discloses a system and method for active and fast recovery of fixed-wing unmanned aerial vehicles. The workstation includes the UAV recovery command workbench and the UAV recovery operation workbench; the UAV recovery operation workbench is used to generate the recovery approach route and generate an automatic control signal; the sighting and launching device includes a high-pressure nitrogen device , UAV capture net launching device, dual-mirror 3D camera and electronic control aiming platform; the flexible mechanical capture device includes UAV capture net and suspension wire, hoisting electric turbine mechanism, boom pulley mechanism and electric control level Tilt turntable. Using the invention to recycle the fixed-wing unmanned aerial vehicle, the entire operation process occupies a small area of ​​the helicopter take-off and landing platform, the time is short, the degree of operation automation is high, the manpower requirement is small, the recovery success rate is high, and the unmanned aerial vehicle's go-around rate is low.

Description

technical field [0001] The invention relates to ship aviation equipment technology, in particular to an active fast recovery system and method for a fixed-wing UAV ship. Background technique [0002] With the rapid development of unmanned systems, land-based unmanned aerial vehicles (UAVs) have been widely used in consumer, industrial, public law enforcement, military and other fields, and have achieved good benefits in use, triggering strong military and civilian market demand. It is a technology and technology developed by major industrial countries in the world. Industrial commanding heights. Fixed-wing UAVs have potential advantages such as high speed, long battery life, high cost-effectiveness, strong mission adaptability, and avoidance of casualties, and are widely recognized by marine powers in the world. [0003] In order to equip fixed-wing UAVs on thousands of surface combat ships, public law enforcement ships, or civilian ships, it is first necessary to break thr...

AI Technical Summary

Problems solved by technology

[0005] 1. The helicopter take-off and landing platform occupies a large area and takes a long time. It takes multiple people to operate the blocking net or the skyhook recovery device, and the entire helicopter take-off and landing platform cannot take off and land the helicopter normally for a long time;

[0006] 2. The reliable contact area between the aircraft and the recovery device is small, and the requirements for the flight trajectory control of the drone are high, resulting in a low recovery success rate and a high go-around rate, especially difficult to achieve recovery operations in high sea conditions;

[0007] 3. When recovering from the collision net, the approach route of the UAV will pass through the projection surface of the mothership, and there is a risk of aircraft-ship collision;

[0008] 4. The blocking distance of the passive recovery device is short, and the weight of the recyclable drone is small. After long-term research by the US Navy, it is very dangerous to recover and recover drones weighing more than 50kg. The skyhook technology can only be used to recover 66kg-level fixed drones. Wing UAV;

[0009] 5. The performance of the UAV aircraft platform, including the flight quality in the turbulent flow at the tail of the ship, the unmanned flight control capability, the aircraft structure and the impact resistance performance of electromechanical equipment, etc., have high requirements, occupy a lot of UAV resources, and limit its use. task execution ability
