The invention relates to a four-engine aircraft, which belongs to the technical field of aircrafts. The four-engine aircraft comprises an aircraft body, a left composite wing, a right composite wing, a tail wing and a landing gear. An operating system and airborne equipment are mounted in the aircraft body. The left composite wing and the right composite wing have same structures and are symmetrically mounted on the left and right sides of the aircraft body. The tail wing is positioned at the tail part of the aircraft body; and the tail wing comprises a horizontal tail wing and a vertical tail wing. The landing gear adopts a wheel type structure. The left composite wing comprises a front wing, a wing shaft, a rear outer wing, a rear inner wing, an outer rotor, an inner rotor, an outer engine and an inner engine. As four rotors are independently controlled and matched with four movable wings, the aircraft is flexible; and as all rotors are mounted under the wings, flow fields of the upper and lower surfaces of the wings can be improved during the rotating of the rotors; therefore, downwash airflow is increased, airflow separation of the upper surfaces of the wings is delayed, the efficiency is increased and the lift coefficient is greatly increased.
