Integral suspended structure of propelling system

The invention relates to the technical field of aircraft structural design, and provides an integral suspended structure of propelling system. One end of the suspended structure is connected to an aircraft wing and the other end of the suspended structure is connected to an aero-engine. The suspended structure is composed of a suspended box segment which is composed of an upper beam, a lower beam, a frame and a side-wall plate. The suspended structure further comprises retro-propulsion cover connection structures which are installed on the left side wall and the right side wall, and is connected with a nacelle retro-propulsion cover connection structure of a front fixed cover and a back movable cover. The retro-propulsion cover connection structure comprises at least one guide rail used for guiding the back movable cover in order to enable the relative suspended box segment of the back movable cover to be opened. A motor retro-propulsion cover is directly connected with the side wall of the suspended box segm
