The invention discloses a fixed-wing helicopter with multiple layers of propellers. A cross beam is arranged at the top of a helicopter body and above the gravity center, longitudinal beams are arranged on the left side and the right side of the cross beam, a row of front-end motors are downwards arranged at the front ends of the longitudinal beams, and a row of front-end thrust propellers with horizontally-arranged rotating faces are installed on the row of front-end motors. A row of longitudinal beam rear-end motor mounting seats are upwards arranged at the rear ends of the longitudinal beams, a row of longitudinal beam rear-end motors are mounted on the row of motor mounting seats, a row of longitudinal beam rear-end tension propellers with horizontally arranged rotating surfaces are mounted on the row of motors, and a first row of high-aspect-ratio fixed wings in front of one or more rows of cross beams are arranged in front of the cross beams and on the longitudinal beams; one or more rows of high-aspect-ratio fixed wings in the first row behind the cross beams are arranged behind the cross beams and on the longitudinal beams, a horizontal empennage is mounted on the tail extension beam, a backward thrust propeller and a forward tension propeller of which the rotating surfaces are perpendicular to the horizontal plane are arranged in the middle of the horizontal empennage, and an undercarriage is arranged below the fuselage near the gravity center. The fixed-wing helicopter is applied to transportation, agricultural operation, forest fire extinguishing, exploration and the like.
