Carrier rocket booster tank structure for biased concentrated force

Abstract

The invention provides a carrier rocket booster tank structure for biased concentrated force. The structure comprises a front short shell, a front tank bottom, a cylinder segment, a rear tank bottom and a rear short shell, wherein the five parts form the whole tank structure through circumferential welded seams and form a sealed container which can store a propellant and bear various loads; the front short shell is welded into a whole by a radial outer reinforced wall plate and two positive outer reinforced wall plates, and the cylinder segment is composed of a mixed inner reinforced wall plate with a concentrated force diffusion function and an oblique inner reinforced wall plate. The carrier rocket booster tank structure solves the bearing and diffusion problem of the biased concentrated force, the biased concentrated force is diffused through the tank structure to become uniformly distributed force, and a good mechanical environment is provided for a cabin behind a tank. The tank structure has the characteristics of high bearing capacity, high structure efficiency, good concentrated force diffusion effect, etc.

Description

technical field [0001] The invention relates to the field of launch vehicle storage tank structures, in particular to a launch vehicle booster storage tank structure with biased and concentrated force. [0002] technical background [0003] The launch vehicle tank is mainly used to store the propellant required for rocket flight and bear various loads of the rocket. Conventional storage tank structures are usually subjected to uniformly distributed forces along the circumferential direction during erection on the ground and during flight, so the short shells and barrel sections of conventional storage tanks usually adopt symmetrically reinforced wall plate structures. The domestic new generation of XX high-thrust bundled launch vehicle adopts the configuration of the core stage plus four liquid boosters. The liquid boosters are bundled around the core stage. The top and side walls of each booster are connected to The core stage is structurally connected, and the tank at the ...

AI Technical Summary

Problems solved by technology

The domestic new generation of XX high-thrust bundled launch vehicle adopts the configuration of the core stage plus four liquid boosters. The liquid boosters are bundled around the core stage. The top and side walls of each booster are connected to The core stage is structurally connected, and the tank at the front end of the booster is subject to a large biased concentrated force due to its close proximity to the binding point. In order to provide a good mechanical environment for the rear cabin, the booster tank must be able to spread the concentrated force become a uniform force, and the conventional tank structure cannot meet the bearing and diffusion requirements of the above-mentioned biased concentrated force

At present, there is no storage tank structure with similar requirements in China, and similar information abroad has not been collected.
