Layered frame for launching vehicle

Abstract

The invention relates to a layered frame for a launching vehicle, which comprises a bottom framework assembly, a middle framework assembly, a left top layer framework assembly and a right top layer framework assembly; the middle layer framework assembly is welded and fixed with the bottom layer framework assembly through lower ends of a supporting upright post and a hanging upright post on a second left longitudinal connecting beam and a second right longitudinal connecting beam; the left top layer framework assembly and the right top layer framework assembly are welded and fixed with the upper ends of the supporting upright post and the hanging upright post; the left end and the right end of a first cross connecting beam of the bottom layer framework assembly are welded and fixed with the left top layer framework assembly, the right top layer framework assembly and the middle layer framework assembly through a left connector and a right connector correspondingly. The layered frame has the advantages of being light in weight, big in load, stable in structure, and relatively low in centroid; the safety of the launching vehicle and the high-speed driving stability are effectively improved.

Description

technical field [0001] The invention relates to a vehicle frame, in particular to a layered integrated vehicle frame for a launch vehicle. Background technique [0002] In the field of military and aerospace, the existing launch vehicle mainly adopts the structure of stacking the top-loading equipment compartment on the ordinary frame. The higher weight and higher center of mass affect the stability of high-speed driving. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a layered frame for a launch vehicle, which has the advantages of light weight, large load, stable structure and low center of mass, and can effectively improve the safety of the launch vehicle and the stability of high-speed driving . [0004] In order to solve the problems of heavy weight, high center of mass and poor stability of the frame of the launch vehicle in the prior art, the present invention provides a layered frame for the launch vehicle, which includes a b...
