Elastic connecting assembly for aero-engine

The invention belongs to the technical field of aero-engine design, and relates to an elastic connecting assembly for an aero-engine. The elastic connecting assembly is arranged between a jet nozzle of an engine and a tail fairing, and comprises an inner shell, a modified inner shell and an outer shell, wherein the outer shell is provided with a notch, and the left part and the right part of the notch are both attached to the inner shell and the modified inner shell. The middle part of the inner shell and the middle part of the modified inner shell are provided with screw holes connected withthe jet nozzle of the engine, and box-shaped structures which protrude relative to the surface of the inner shell and the surface of the modified inner shell are arranged at the parts of the screw holes. The stress distribution of the elastic connecting assembly is improved through the box-shaped structures, so that fatigue cracks are avoided. 本申请属于航空发动机设计技术领域，涉及一种航空发动机用弹性连接组件，设置在发动机的尾喷口与机尾罩之间，所述弹性连接组件包括内壳体、修形内壳体以及外壳体，外壳体
