Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle recovery devices, in particular to an unmanned aerial vehicle recovery system guiding parachute shooting mechanism. Background technique [0002] Due to the advantages of unmanned aerial vehicles, fast flight speed, small size, low cost, and convenient use, UAVs have been widely used in military reconnaissance fields in various countries as target aircraft, reconnaissance aircraft, fighter jets, and bait aircraft. The recovery methods of drones mainly include hollow recovery, interception net recovery, air cushion landing recovery and parachute recovery. Because the parachute recovery method has the advantages of wide application range, high cost performance, no need for complicated and expensive navigation systems and special landing sites, so the existing UAVs generally adopt the parachute recovery method. [0003] The existing parachute recovery system generally consists of three parts: ...
