The invention discloses a variable pitch fixed wing power system of an unmanned aerial vehicle. The variable pitch fixed wing power system comprises paddles, an eccentric pin, a sliding block, a variable pitch sliding base, a variable pitch piston, a servo motor, a rotor wing main shaft, a transmission shaft, a drive box, a conveying belt, a drive wheel, an engine, a through hole, a partition plate, a pitch feedback lever, a variable pitch oil cylinder and a push-pull lever. The variable pitch fixed wing power system is characterized in that the eccentric pin is arranged at the lower ends of the paddles and connected with the paddles, the sliding block is arranged at the lower end of the eccentric pin, and the variable pitch sliding base is arranged at the lower end of the sliding block; the sliding block is connected with the variable pitch sliding base, and the push-pull lever is arranged at the lower end of the variable pitch sliding base; the push-pull lever is connected with the variable pitch sliding base, the variable pitch piston is arranged at the lower end of the push-pull lever, and the variable pitch piston is connected with the push-pull lever; and the variable pitch oil cylinder is arranged at the lower end of the variable pitch piston, the pitch feedback lever is arranged at the lower end of the variable pitch oil cylinder, and the pitch feedback lever is connected with the variable pitch oil cylinder. According to the variable pitch fixed wing power system, the rotating speed of the paddles can be stabilized, the effect of low rotating speed and high efficiency is achieved, accordingly, the paddle efficiency is improved, and the effects of saving energy and improving the cruising ability are achieved.
