Tiltrotor mixed multi-state aircraft with operational control surfaces

The invention provides a tiltrotor mixed multi-state aircraft with operational control surfaces. The aircraft comprises a fuselage which contains two parallelly and symmetrically arranged fixed wings and a middle support frame. There are four rotor wings on the two fixed wings. The two fixed wings are provided with operational control surfaces. By controlling rotation of the control surfaces through a steering engine, motions such as pitching, roll and adjustment of course angle, are realized. According to the aircraft, advantages of a multi-rotor aircraft and a fixed-wing aircraft are integrated and multi-rotor wings and the operational control surfaces are mounted on the multiple fixed wings. In all parts, propellers, a rotating shaft of a motor, the steering engine, a steering engine operating lever and the control surfaces can rotate normally, but relative positions of the other parts are not changed. Especially the mounting positions of the fuselage, the motor and the propellers are relatively fixed. The aircraft has three flight states: a vertical take-off and landing or spot hover state, a cruising flight state and a transition state.
