Embodiment Construction

[0014] Referring to the accompanying drawings: the aircraft engine suspending structure of the present application is located below the wing 1, and is used to suspend the engine 3 on the aircraft wing. Therefore, the suspending structure 2 must meet the necessary rigidity and strength, and at the same time try to Possibly reduce own weight. The aircraft engine suspension structure of the present application includes a suspension body and a plurality of joints for connecting with adjacent structures. It is characterized in that the suspension body and the joints are an integral structure of additive manufacturing, and the suspension body 2 is a A hollow truss structure composed of a plurality of edge strips and a plurality of ribs, the edge strips constitute the outline of the hanging body, the ribs are staggered between the edge strips, and the joint base is connected with the adjacent edge strips and ribs . In practice, the outline of the hanging body includes four side edge...

Abstract

The invention discloses an aircraft engine hanging structure. The aircraft engine hanging structure comprises a hanging body and a plurality of joints for connecting with adjacent structures, whereinthe hanging body and the joints are an integral structure through additive manufacturing; and the hanging body is of a hollow truss structure composed of a plurality of edge strips and a plurality ofrib strips, the edge strips constitute the contour of the hanging body, the rib strips are distributed between the edge strips in a staggered mode, joint bases are connected with the adjacent edge strips and rib strips, all loads are transferred through the rib strips, and the weight of the structure is reduced.

Description

technical field [0001] The invention belongs to the design of aircraft structure, in particular to an aircraft engine hanging structure. Background technique [0002] The aircraft engine suspension structure is an aircraft engine installation structure, which is located under the wing and is used to suspend the engine on the wing. Due to the complex load bearing and high ambient temperature of the aircraft engine suspension structure, it requires high structural rigidity. . Therefore, the traditional aircraft engine suspension structure is limited by the processing technology, and it is a combined structure, which has the disadvantages of complex structure, difficult installation and coordination, difficult processing, and heavy weight. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an engine that can withstand the complex load of the engine, can be used in high temperature and high vibration environment, can greatly improve the struc...
