Abstract

The invention discloses a tilting hybrid power fly-by-wire vertical take-off and landing fixed-wing unmanned aerial vehicle. The unmanned aerial vehicle comprises a body, a tail, a rotor wing assembly, a tilting assembly and a power assembly, the power assembly is installed in the body and comprises an oil tank, an engine, a generator and a battery, an output shaft of the engine drives the generator to work, and the battery is connected with the generator and a tilting motor through cables. By adopting the technical scheme of combining a hybrid power system and a tilting mechanism, the characteristic of high energy density of a fuel engine can be fully utilized by the unmanned aerial vehicle, so that the flight time and the hovering time are greatly prolonged, and the performance is optimized and improved; meanwhile, double backups are provided for an energy system, so the unmanned aerial vehicle can normally fly even if the engine breaks down; in the fixed-point hovering process, onlythe battery is used for supplying power when a common vertical fixed-wing aircraft hovers, the energy of the generator is increased, and the power output of the battery is reduced, so the hovering time can be prolonged by more than one time compared with hovering time of a common conventional fixed-wing unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a fixed-wing unmanned aerial vehicle, in particular to a tilting hybrid telex vertical take-off and landing fixed-wing unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicles. Background technique [0002] UAV is a kind of unmanned aircraft mainly controlled by radio remote control or senior program. It has many advantages such as small size, low cost, convenient use and maintenance, etc., and its application demand in the fields of national defense and civil use has increased sharply. With the development of technology, the performance of UAVs has been continuously improved, and the types of drones have continued to increase. According to the power source, it can be divided into electric drones, oil-powered drones, oil-electric hybrid drones, and other energy (such as hydrogen fuel) drones; by use, it can be divided into military drones, industrial drones According to the classification of flight...
