The invention relates to the technical field of aero-engines, and provides an aero-engine mounting rack and an aircraft. The aero-engine mounting rack comprises a support assembly, one end of the support assembly is used for being connected with a firewall, the other end of the support assembly is provided with an engine connecting frame, and the engine connecting frame is arranged on an engine in a sleeving mode; a plurality of damping devices are arranged on the inner side face of the engine connecting frame in the circumferential direction and connected with the outer circumferential face of the engine. By arranging the engine connecting frame, when the two ends of an engine are heated and deform in the axial direction, the two ends of the engine cannot generate stress on the support assembly to cause deformation of the mounting support, the stress cannot be transmitted to an aircraft structure through the support assembly, and the flying stability of an aircraft is prevented from being affected; the multiple damping devices are arranged on the inner side face of the engine connecting frame in the circumferential direction, vibration of the engine can be buffered, and when the engine is heated and deforms in the radial direction, it is avoided that the engine directly acts on the support assembly, and the installation support cracks and loses efficacy.
本发明涉及航空发动机技术领域,提供一种航空发动机安装架及飞机,包括支架总成,支架总成的一端用于与防火墙连接,支架总成的另一端设置有发动机连接框,发动机连接框套设在发动机上,发动机连接框的内侧面沿周向设置有多个减震装置,减震装置与发动机的外圆周面相连接;本发明通过设置发动机连接框,当发动机受热两端沿轴向变形时,发动机的两端不会对支架总成产生应力造成安装支架变形,并且也不会通过支架总成将应力传递给飞机结构,避免影响飞机飞行的稳定性;通过在发动机连接框的内侧面沿周向设置有多个减震装置,不仅能缓冲发动机的振动,而且当发动机受热沿径向发生变形时,避免直接作用于支架总成,造成安装支架开裂失效。
