The invention discloses a long-endurance hybrid power UAV (Unmanned Aerial Vehicle). The UAV comprises two propeller engines, double tail booms and a pair of wings, wherein the propeller engines are respectively and relatively arranged in the front or at the back of a UAV body; the double tail booms are arranged at the rear part of the UAV body and the pair of wings is arranged on the UAV body; the two propeller engines are a methanol engine and a motor and both are arranged on the axis of the UAV body. According to the UAV provided by the invention, by adopting a high mounted wing with high aspect ratio, double tail booms layout, and the power configuration that the methanol engine is behind the motor, the oil and electric hybrid power has the characteristics of long-endurance of an oil driven airplane and the reliability of an electric driven airplane; furthermore, the motor can ensure that the oil-driven airplane is capable of making a return voyage when an extinguishment-trouble is caused, so that the safety of the air-plane, surrounding buildings and personnel can be ensured, and the survival rate of the airplane can be improved; more powerful power can be provided when the motor and the methanol engine are operating at the same time, so that the maximum load of the UAV can be improved, and the take-off distance can be shortened, besides the requirements on a take-off site by the UAV can be reduced, therefore, the UAV can take a plurality of task equipment to implement tasks.
