Launch vehicle line type bundling separation device

Abstract

A launch vehicle line type bundling separation device belongs to the field of aerospace structure design. The launch vehicle line type bundling separation device is of a plate structure arranged in the axis direction of a vehicle by taking a separation plate type expansion pipe as a separation system, and the entirety of the bundling separation device is similar to an I-shaped section; the bundling separation device comprises four groups of bundling separation structures, inter-tank sections connected to central stages of the vehicle, and oblique nose cones of boosters. Each group of the bundling separation structures are composed of four I-shaped square plates, and each I-shaped square plate comprises two connecting plates, two separating plates, a metal flat pipe, fillers and a detonating fuse; the metal flat pipe is located between the two connecting plates, and the fillers are placed in the metal flat pipe; the detonating fuse is arranged in the fillers, and used for providing energy during separation; and the two separation plates are used for connecting the ends of web plates on both sides of the two connecting plates. The bundling separation device provided by the inventionhas the advantages of uniform force transmission, weight reduction, improvement of carrying capacity of the vehicle, high bearing capacity and separation reliability, no pollution and small impact during separation.

Description

technical field [0001] The invention belongs to the field of aerospace structure design and manufacture, relates to the field of force transmission structure design between a bundled launch vehicle core stage and a booster, and particularly relates to the field of engineering structure optimization. Background technique [0002] In order to meet the requirements of launching different types of satellites, spacecraft, orbiters, interstellar probes and other spacecraft, it is necessary to develop vehicles with different carrying capabilities. In order to shorten the development cycle and reduce the development cost, the vehicle that combines the existing different thrust vehicles according to the requirements becomes the first choice for spacecraft design. At present, the combined connection method between carriers generally adopts "vertical plus level, horizontal bundling". This solution is based on the original carrier, vertically combining two to three-stage carriers into ...
