The invention provides a sleeving type unmanned aerial vehicle rear fuselage structure and an unmanned aerial vehicle comprising the rear fuselage structure. The cup joint type unmanned aerial vehicle rear fuselage structure comprises a framework assembly and a skin assembly, the framework assembly comprises a middle-rear fuselage butt joint frame, an engine mounting frame, a plurality of short beams and an engine hanging piece, the middle-rear fuselage butt joint frame is connected to a middle fuselage section of an unmanned aerial vehicle in a cup joint mode, one end of each short beam is connected to the middle-rear fuselage butt joint frame, and the other end of each short beam is connected to the engine mounting frame. The skin assembly comprises a rear fuselage skin, a reinforcing frame and a tail frame. One end of the engine hanger is connected to the engine mounting frame, and the other end of the engine hanger is connected to the reinforcing frame. According to the structure, the mounting and dismounting space of the engine is open, a covering cap does not need to be designed for dismounting and maintenance, the operability is high, the assembling efficiency of the engine can be effectively improved, and the time and labor cost for maintaining and testing equipment such as the rear fuselage section engine and the steering engine is reduced. And the problems of overlarge bearing and stress concentration of the engine mounting frame structure are avoided, and the force transmission efficiency of the rear fuselage structure is improved.
本发明提供了套接式无人机后机身结构及包含该后机身结构的无人机。套接式无人机后机身结构包括骨架组件和蒙皮组件,骨架组件包括中后机身对接框、发动机安装框、多个短梁和发动机吊挂件,中后机身对接框套接至无人机中机身段,短梁的一端连接至中后机身对接框另一端连接至发动机安装框。蒙皮组件包括后机身蒙皮、加强框和尾框,发动机吊挂件的一端连接至发动机安装框另一端连接至加强框。根据该结构,发动机的安装和拆卸空间开敞,无需设计口盖进行拆装维护,可操作性强,能够有效提升发动机的装配效率,降低后机身段发动机、舵机等设备维护测试的时间人力成本。还避免了发动机安装框结构承载过大和应力集中问题,提高了后机身结构的传力效率。
