The invention discloses an oil-electricity hybrid unmanned aerial vehicle power system and a control method thereof. The oil-electricity hybrid unmanned aerial vehicle power system comprises a transmission unit, a propeller, a screw pitch changing unit and a steering engine unit. The transmission unit is used for outputting alternating current after receiving the starting signal sent by the receiver, and the alternating current is used for driving a propeller; the propeller is used for rotating under the driving of the transmission unit and providing energy required by flight; the pitch changing unit is used for changing the pitch of the propeller and controlling the flight state of the unmanned aerial vehicle; the steering engine unit is used for judging the driving direction after receiving the screw pitch control signal sent by the receiver, driving the screw pitch changing unit and judging whether the screw pitch changing unit reaches a preset position or not; wherein the transmission unit comprises a generator and a motor, the motor is connected with the propeller, the generator directly drives the motor by outputting alternating current, and the motor drives the propeller. According to the unmanned aerial vehicle, the purposes of reducing the self weight of the unmanned aerial vehicle and effectively saving the manufacturing cost are achieved.
