Large-load lightweight aircraft

Abstract

The application provides a large-load lightweight aircraft, which comprises a fuselage, wings and several tail wings at the tail of the fuselage, wherein the fuselage comprises a front fuselage part and a rear fuselage part which are fixed through a butt joint frame; the front fuselage part comprises a front fuselage inner frame and a front fuselage outer skin structure, and the rear fuselage part comprises a rear fuselage inner frame and a rear fuselage skin structure, two tail wing connecting heads are symmetrically installed on the rear fuselage inner frame; the wings comprise a wing main body and an aileron, the wing main body comprises a wing skeleton and a wing outer skin structure; the aileron comprises an aileron body and aileron rib boxes installed at both ends of the aileron body; the tail wing comprises a stabilizer provided with a mounting groove at the rear side, and a control surface is installed in the stabilizer mounting groove, and the control surface is driven by a transmission shaft. The application maximally utilizes composite materials for lightweight design, and metal materials are used for reinforcement at key stress positions, so that the light weight, the maneuvering performance, the aerodynamic performance, the durability and the service life are guaranteed.
