Landing method for flameout of air engine of large freight unmanned aerial vehicle

Abstract

The invention discloses a landing method for flameout of an air engine of a large freight unmanned aerial vehicle, and the method comprises the following steps: planning an air route, planning the flight path of the unmanned aerial vehicle, and selecting the shortest flight path, so that the oil consumption of the unmanned aerial vehicle can be reduced, and the unmanned aerial vehicle can fly for multiple times; carrying out flight planning, wherein the unmanned aerial vehicle flies on a preset route during use; and carrying out forced landing planning: after the engine of the unmanned aerial vehicle flames out, carrying out emergency forced landing on the unmanned aerial vehicle. A plurality of landing preparation sites are bound in advance, then after an air engine flames out, the optimal landing site is selected for landing according to the current flight height, speed and distance, in this way, it can be ensured that the unmanned aerial vehicle can select the emergency landing site closest to the unmanned aerial vehicle for emergency landing in the emergency state, and therefore safe landing of the unmanned aerial vehicle is improved; and meanwhile, the forced landing point is set in advance, the forced landing environment is high in controllability, and the problem that the unmanned aerial vehicle is difficult to land due to the complex environment during forced landing can be solved.

Description

technical field [0001] The invention belongs to the technical field of cargo unmanned aerial vehicles, and in particular relates to a landing method for a large-scale cargo unmanned aerial vehicle with an air engine flameout. Background technique [0002] Cargo UAV is a kind of equipment equipped with advanced flight control system and command system. It completely gets rid of the dependence on the pilot and can realize the aircraft in the control center. Sometimes unexpected situations occur during the flight of the UAV. For example, no one If the air engine of the drone is turned off, the drone loses its power source and cannot continue to fly. The drone will be in a state of disordered flight. When the battery is exhausted, it will fall and cannot make a safe landing. cause greater economic losses. [0003] The existing UAVs use the emergency power system for forced landing. The forced landing data is a single data, which is not applicable universally, and the forced lan...

Problems solved by technology

[0004] Aiming at the problem that the forced landing point of the existing cargo UAV is random, and the forced landing environment is not conducive to the safe landing of the UAV, the present invention provides a landing method for large-scale cargo UAV with the air engine turned off, by setting multiple forced landing points on the route , and carry out safety management on the forced landing point, provide a safe forced landing environment for the drone, and increase the safety of the forced landing of the drone
