The invention relates to the technical field of aero-engines, and discloses a mounting and connecting structure of an aero-engine, the aero-engine comprises an aircraft mounting bracket and an engine mounting section, the aircraft mounting bracket is provided with a first mounting hole, the engine mounting section is provided with a second mounting hole, and the first mounting hole and the second mounting hole are communicated. The mounting and connecting structure of the aero-engine comprises a connecting piece, a first buffering piece and a second buffering piece. A connecting piece sequentially penetrates through the second mounting hole and the first mounting hole; the first buffer piece is arranged on the periphery of the connecting piece in a sleeving manner and is arranged between the connecting piece and the first mounting hole; and the second buffer piece is arranged on the periphery of the first buffer piece in a sleeving manner and is arranged between the first buffer piece and the second mounting hole. Connection and stress load transmission of the aero-engine and an aircraft cabin can be realized, and absorption, suppression and relaxation of vibration of the aero-engine can also be realized; and meanwhile, the function of installing the connecting piece and the damping device is achieved.
