High-performance fiber fabric and foam based flexible protection structure

Abstract

The invention discloses a high-performance fiber fabric and foam based flexible protection structure. The flexible protection structure includes a buffer screen, foams, filling screens and a back wall; the buffer screen is used for breaking space debris; the foams are used for adjusting the compression amount or the swelling amount of the protection structure; the filling screens are used for disintegrating space debris cloud; the back wall is used for capturing the space debris cloud; andthe buffer screen, the foams, the filling screens, and the back wall are successively glued through an adhesive. The flexible protection structure can be folded and compressed through the filling screens, is easy to launch, and can make up the defect of low reliability of the conventional protection structures; and the protection spacing of the flexible protection structure can break through a space limit of a rocket fairing through the foams, the protection ability of the flexible protection structure is significantly enhanced, and the problem that the conventional protection structures are much in energy consumption and are poor in environment suitability.

Description

technical field [0001] The invention relates to a flexible protection structure based on high-performance fiber fabric and foam, which is especially suitable for spacecraft to resist the impact of space debris, and belongs to the technical field of passive protection of space debris. Background technique [0002] Space debris is likely to cause various types of damage to spacecraft. The type and degree of damage depend on the size, configuration, working time of the spacecraft, and the quality, density, speed, and impact direction of space debris. Types of impact damage include perforation of the panel, rupture of the pressure vessel, degradation of the porthole glass, degradation of thermal control performance and leakage of the airlock. [0003] Aiming at the impact threat of space debris, the usual practice of aerospace engineering is: first, assess the space debris impact risk of the spacecraft, and then take certain protective measures to improve the ability of the spac...
