The invention discloses an engine statically indeterminate mounting structure which comprises an engine air inlet channel fixing ring, an engine body fixing ring and an exhaust nozzle fixing ring which are coaxially arranged, and a fixing frame plate is coaxially arranged between the engine air inlet channel fixing ring and the engine body fixing ring. Thrust beams are symmetrically arranged on the left side and the right side of the fixed frame plate in the direction parallel to the axis of the fixed frame plate, and a main installation joint is arranged at the end, close to the fixed frame plate, of each thrust beam. Auxiliary mounting section adjusting pull rod assemblies are symmetrically hinged to the left side and the right side of the engine body fixing ring, and spray pipe lifting point adjusting pull rod assemblies are symmetrically hinged to the left side and the right side of the top of the exhaust spray pipe fixing ring. The problems that the force transmission efficiency is not high and the weight of the structure thrust beam is increased due to the fact that the force transmission direction of the engine main installation section supporting face is not consistent with that of the airplane structure, and additional redundancy is designed for a single-engine airplane, and the stability and reliability of the engine installation structure are guaranteed.

    本发明公开了一种发动机静不定安装结构,包括同轴设置的发动机进气道固定环、发动机机体固定环、尾喷管固定环,所述发动机进气道固定环与发动机机体固定环之间同轴设置有固定框板,所述固定框板的左右两侧沿平行于固定框板轴线的方向对称设置有推力梁,所述推力梁靠近固定框板的一端设置有主安装节;所述发动机机体固定环的左右两侧对称铰接设置有辅助安装节调节拉杆组件,所述尾喷管固定环的顶部的左右两侧对称铰接设置有喷管吊点调节拉杆组件;本发明能够解决发动机主安装节支撑面与飞机结构传力方向不一致产生额外的剪力造成传力效率不高和结构推力梁增重的问题,并针对单发飞机设计额外的余度,保证发动机安装结构的稳定性和可靠性。
