The invention relates to a multi-propeller airplane and belongs to the technical field of aircrafts. The multi-propeller airplane comprises an airplane body, a left composite aerofoil, a right composite aerofoil, an empennage and an undercarriage. An operation system and airplane-borne equipment are assembled in the airplane body. The empennage is located at the tail of the airplane body and comprises a horizontal empennage body and a perpendicular empennage body. A wheel type structure or a skidding and wheel type combined structure is adopted in the undercarriage. The left composite aerofoil and the right composite aerofoil are of the same structure and are symmetrically installed on the left side and the right side of the airplane body. Two or three or four rotor wings are assembled in the left composite aerofoil, and each rotor wing is driven by an engine. Aerofoil panels of the left composite aerofoil comprise the front aerofoil panel and the rear aerofoil panel, and the front aerofoil panel and the rear aerofoil panel can rotate around a wing shaft in a deflecting mode. All the rotor wings are located below the wing shaft. The multi-propeller airplane needs a small taking-off and landing field and can perpendicularly take off and land. Generated lifting force is large, and the multi-propeller airplane is safe, stable and flexible.
