The invention discloses a double-engine aircraft and belongs to the field of aircrafts. The double-engine aircraft comprises an aircraft body, a left wing, a left rotor wing, a left engine, a right wing, a right rotor wing, a right engine, a tail and undercarriages, wherein the left wing and the right wing are symmetrically mounted on the left side and the right side of the aircraft body; the left wing comprises a front-section fixed part and a rear-section movable part; the left rotor wing and the right rotor wing have the same size, but rotate in opposite directions; with a horizontal plane as a benchmark, the degree of the maximum downward deflection angle of the rear-section movable part of the left wing is equal to that of the included angle between the front-section fixed part of the left wing and the horizontal plane; when the rear-section movable part of the left wing is deflected to the lowest position, the leading edge of the left wing is higher than the trailing edge of the left wing; the rotary plane of the left rotor wing is slightly inclined forwards and downwards or is located in the horizontal position; during rotation of the left rotor wing and the right rotor wing, flow fields of the upper surfaces and the lower surfaces of the left wing and the right wing can be changed, the downwash flow is increased, and airflow separation of the upper surfaces of the left wing and the right wing is delayed. The aircraft is safe, efficient and high in maneuverability.
