Composite material high-pressure gas cylinder fixing device dedicated to space vehicles

Abstract

The invention provides a fixing device special for an aerospace vehicle composite material high-pressure gas cylinder. The device is used for fixing the high-pressure gas cylinder, and the high-pressure gas cylinder is provided with a front end clamping part and a rear end clamping part which are separately provided with dented planes. The device at least comprises a front end support seat, a front end support, a rear end support seat and a rear end support, wherein the front end support seat and the front end support clamp the front end clamping part of the high-pressure gas cylinder, the front end of the high-pressure gas cylinder is fixed to the front end support seat through a first fastening structure, the rear end support seat and the rear end support clamp the rear end clamping partof the high-pressure gas cylinder, and the rear end of the high-pressure gas cylinder is fixed to the back end support seat through a second fastening structure. According to the fixing device for the high-pressure gas cylinder, the front end clamping part and the rear end clamping part of the high-pressure gas cylinder are clamped and fixed respectively in a matched mode, and the radial rotationof the high-pressure gas cylinder is limited, so that the high-pressure gas cylinder is more reliably fixed, and the reliability of the fixing device for the high-pressure gas cylinder is improved.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas cylinder fixing equipment, in particular to a composite material high-pressure gas cylinder fixing device specially used for aerospace vehicles. Background technique [0002] High-pressure gas cylinders for aerospace vehicles are pressure vessels used to store high-pressure gases (such as oxygen, nitrogen, hydrogen, helium, etc.), and have high requirements for the space environment adaptability, dimensional stability, and quick assembly and connection of materials. . Traditional high-pressure gas cylinders are mostly made of metal materials, and the negative mass of the structure is large. At present, high-pressure gas cylinders are all made of advanced composite materials. Composite materials have become the preferred high-pressure-resistant gas cylinder materials due to their excellent properties such as light weight, high structural efficiency, good fatigue resistance, and good dama...
