Parachute fixed-wing unmanned aerial vehicle autonomous fixed-point recovery method

The invention provides a parachute fixed-wing unmanned aerial vehicle (UAV) autonomous fixed-point recovery method comprising the following steps: setting a recovery point and a recovery course, and judging whether the setting has recovery conditions; when autonomous recovery is needed, generating an approach descending route and making an aircraft fly along the approach descending route; generating a recovery route, and making the aircraft fly along the recovery route; correcting the recovery route according to the measured wind speed and direction on the aircraft, and making the aircraft fly along the corrected recovery route; and finally, making an engine stop and opening a parachute when the aircraft approaches the recovery point. By adopting the method of the invention, the procedure of aircraft recovery operation is simplified greatly, the operating burden of UAV operators is lightened, the autonomy of UAVs is enhanced, and the dependence of UAVs on communication conditions is reduced.
