Abstract

An embodiment of the present invention provides a lightweight diffusion structure for the hoisting position of an aircraft fuel tank, including: a first ring frame and a second ring frame that are installed on the casing of the fuel tank and are fixedly connected to the casing in the circumferential direction ; the first crossbeam and the second crossbeam that are installed on the housing and fixedly connected with the housing; and the connecting head arranged on the housing; wherein, the first crossbeam and the first The ring frame is fixedly connected; the second beam is fixedly connected to the first ring frame and the second ring frame respectively, and the connecting head is located in the space surrounded by the first beam and the first ring frame . The scheme of the invention can meet the use requirement of the dispersed transmission of the extra large concentrated force of the aviation fuel tank.

Description

technical field [0001] The invention relates to the technical field of hoisting structures for fuel tanks of aviation and aerospace vehicles, in particular to a lightweight diffusion structure for the hoisting position of fuel tanks of aircraft. Background technique [0002] Aviation fuel tank refers to the thin-walled box structure hung under the fuselage or wing of aviation and aerospace vehicles. The thin-walled box structure is a streamlined structure with a thick middle and sharp ends. shell structure. In order to meet the needs of aircraft hanging and dropping, aviation fuel tanks generally have 2 or 3 points of connecting structure with the hanging and dropping of aviation and aerospace vehicles, one of which is the most important hanging point. More than 80% share of fuel tank overload load. [0003] In the development process of an aviation fuel tank, the load of the lifting point reaches 27t, and the thickness of the thin-walled shell connected to it is 2mm. Ther...
