Fuel-electricity hybrid power unmanned aerial vehicle

Abstract

The invention discloses a fuel-electricity hybrid power unmanned aerial vehicle. The fuel-electricity hybrid power unmanned aerial vehicle comprises a main vehicle frame, two subsidiary vehicle frames, two main rotors, four subsidiary rotors, a fuel engine and a plurality of electric engines, wherein the two main rotors are arranged at the two ends of the main vehicle frame correspondingly, and the four subsidiary rotors are arranged at the four ends of the two subsidiary vehicle frames correspondingly. The fuel engine supplies power to the two main rotors, and each electric engine supplies power to the corresponding subsidiary rotor. The fuel engine and the electric engines are matched for use, the fuel engine drives the two main rotors to supply lift force and advancing power to the unmanned aerial vehicle, and the electric engines drive the four subsidiary rotors to control postures of pitching, rolling, yawing and the like of the unmanned aerial vehicle. The two main rotors are controlled only by one fuel engine, various parameters such as the rotating speeds of the two main rotors can be consistent easily, a complex control system for adjusting does not need to be matched, therefore the fuel-electricity hybrid power unmanned aerial vehicle has the advantages of large load and long cruise duration, meanwhile, the structure is concise, control is easy, and the development and manufacturing costs are reduced by a large margin.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an oil-electric hybrid unmanned aerial vehicle. Background technique [0002] The drones currently used in the civilian market are mainly multi-axis (also known as multi-rotor) drones. [0003] Commonly used small UAVs are mostly powered by pure electric or pure fuel engines. Pure electric engines are easy to control and have high stability, but their endurance is poor. Pure fuel engines have high requirements on oxygen concentration, and the sensitivity of response control is poor, so it is difficult to apply to high-altitude, high-speed and areas that require precise positioning or stable aircraft. [0004] If multiple fuel engines are matched with multiple electric engines, due to the poor consistency of the fuel engines, even if the fuel engines of the same specification and model are input to the same throttle controller, the output power of each fuel engine will be ...
