The invention belongs to a double-paddle aircraft and belongs to the technical field of aircrafts. The aircraft comprises an aircraft body, a left composite wing, a right composite wing, empennages and an undercarriage. A control system and airborne devices are arranged in the aircraft body. The left composite wing and the right composite wing are identical in structure and are symmetrically arranged on the left side and the right side of the aircraft body. The empennages are located on the tail of the aircraft body and include the horizontal empennage and the vertical empennage. The undercarriage is of a wheel type structure. The left composite wing comprises a main wing body, an outer auxiliary wing body, an inner auxiliary wing body, a rotary wing body and an engine, the outer auxiliary wing body and the inner auxiliary wing body can deviate, the rotation plane of the rotary wing body is located in the horizontal position, and the rotary wing body is located below the front edge of the inner auxiliary wing body. When the rotary wing bodies rotate, flow fields of the upper surfaces and the lower surfaces of the wings can be improved, downwash air flow is increased, and air flow separation of the upper surfaces of the wings is slowed down. The aircraft is safe, efficient and high in maneuverability.
