Recovery system for small-sized fixed-wing unmanned aerial vehicle

Abstract

The invention provides a recovery system, with the characteristics of accurate site directed recovery, small recovery field, damage prevention of sensitive equipment at the front end of an unmanned aerial vehicle (UAV) and low requirement of the wing strength, for a small-sized fixed-wing UAV and belongs to the field of small-sized fixed-wing UAV recovery system. The recovery system for the small-sized fixed-wing UAV comprises a foldable sky hook, a block device, a buffering energy-absorbing device and a manipulator-arm-type recovery bracket, wherein the foldable sky hook is fixed to the small-sized fixed-wing UAV, and when detecting the block device, the small-sized fixed-wing UAV controls the foldable sky hook to bounce to hook on the block device to realize the blocking of the small-sized fixed-wing UAV; the buffering energy-absorbing device is used to damp the impact kinetic energy of the block device; and the manipulator-arm-type recovery bracket is used to place the small-sized fixed-wing UAV which is blocked to a designated parking position. The recovery system for the small-sized fixed-wing UAV is suitable for recovery environment with confined space such as ground, ships and the like.

Description

technical field [0001] The invention relates to a recovery system for a small fixed-wing unmanned aerial vehicle, in particular to a recovery system for a small fixed-wing unmanned aerial vehicle on the ground with a skyhook on the top of the aircraft and a carrier-mounted small fixed-wing unmanned aerial vehicle, which belongs to the field of recovery of small fixed-wing unmanned aerial vehicles. Background technique [0002] With the wide application of high-tech in weapons and equipment, the research and development of UAVs has made breakthrough progress, and has frequently appeared in several local wars, and has repeatedly made military exploits, and has been highly praised by military personnel from various countries. Among them, fixed-wing UAVs have been used most in the military field due to their advantages in flight speed and flight distance, but their launch and recovery are more difficult than unmanned helicopters and multi-rotor UAVs. The length of UAV recovery t...

Problems solved by technology

The parachute recovery method will occupy the space and load inside the fuselage, and it cannot be recovered at a precise point, which may easily cause damage to the drone

In the collision net recovery method, the impact part with the blocking net is the front of the fuselage, which may easily cause damage to the sensitive equipment at the front of the UAV, and the propeller of the UAV is easily entangled with the blocking net, which is not suitable for fixed-wing UAVs with propellers.

The wing collision line recovery method is connected by the wing tip hook on the wing and the vertical arresting rope, which can realize precise point recovery, but it has high requirements on the strength of the wing of the UAV, and the small unmanned vehicle with high aspect ratio Difficult to apply
