Fuel power quadrotor unmanned aerial vehicle

The invention relates to the technical field of unmanned aerial vehicles, and in particular relates to a fuel power quadrotor unmanned aerial vehicle which comprises a fuel engine, a transmission mechanism, a brake mechanism and a flying control system, wherein the flying control system is connected with the fuel engine, the transmission mechanism and the brake mechanism; the fuel engine is used for driving four rotors of the unmanned aerial vehicle to rotate through the transmission mechanism according to control orders of the flying control system; the brake mechanism is used for respectively controlling the rotation speeds of the four rotors according to the control orders of the flying control system. Compared with the prior art, the fuel power quadrotor unmanned aerial vehicle has the advantages that the fuel engine is adopted to replace batteries to be used as power of the quadrotor unmanned aerial vehicle, so that the cruising power of the quadrotor unmanned aerial vehicle is greatly improved, and meanwhile the cost of the quadrotor unmanned aerial vehicle is lowered.
