The invention discloses an aircraft and a rear fuselage structure thereof, the rear fuselage structure is a structure capable of transmitting the out-of-plane bending moment of a reinforcing frame at a large opening of the aircraft, all parts are integrally machined and formed by adopting 7050-T7451 aluminum alloy, the process is mature, a cross beam in the structure can bear the out-of-plane bending moment at the reinforcing frame, and other parts can transmit the longitudinal load of a fuselage, so that the rear fuselage structure has the advantages of being simple in structure and convenient to use. And the structure can meet the requirement of opening a large opening cover on the machine body. Meanwhile, the structure is high in load transfer capacity, light in structure weight and easy to assemble, has the anti-corrosion capacity, and is good in manufacturability and feasibility due to the fact that common standard parts are used.

    本发明公开了一种飞机及其后机身结构,是在飞机大开口处可传递加强框面外弯矩的结构,所有零件均采用7050‑T7451铝合金整体机加成型,工艺成熟,此结构中的横梁可承受加强框处的面外弯矩,其余零件可传递机身的纵向载荷,并且此结构能够满足在机身上开大口盖的需求。同时,此结构传载能力强,结构重量轻,装配简单,具有防腐蚀的能力,并且使用常用的标准件,工艺性和可行性良好。
