Fuel power multi-rotor unmanned aerial vehicle

The utility model is suitable for the field of unmanned aerial vehicle power supply and control and provides a fuel power multi-rotor unmanned aerial vehicle which comprises a power unit, a driving unit, a control unit and a monitoring sensing unit. The control unit is simultaneously connected with the power unit, the driving unit and the monitoring sensing unit; and the power unit is further simultaneously connected with the driving unit and the monitoring sensing unit. The power unit comprises a generating module and an AC-DC conversion module; after the power unit receives control instructions transmitted by the control unit, the generating module outputs an alternating current, and a direct current is output to the driving unit and the monitoring sensing unit after the alternating current is converted through the AC-DC conversion module. According to the fuel power multi-rotor unmanned aerial vehicle, a fuel engine is adopted to provide power, the power is converted into electric power through a generator to drive a direct-current motor to drive rotors to rotate, so as to provide flight dynamics for the unmanned aerial vehicle; in case of emergencies such as engine faults, a standby storage battery can be started to provide electric power to achieve safe forced landing; the fuel power multi-rotor unmanned aerial vehicle is simple in structure, and the endurance is greatly prolonged compared with a traditional battery-driven multi-rotor flight vehicle.
