Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of high cost, difficulty, or even difficulty in realizing large-sized protective screens that are space-assembled by one-time launch or multiple launches, and the low folding efficiency and low deployment reliability of protective screens that are mechanically unfolded. , The volume is small after unfolding, it is difficult to construct multi-layer protection with more than three layers or more layers, and solve the problems of large folding volume, inflexible folding method, large emission volume and expanded volume of the existing rigid protective screen small problems, and then provide an in-orbit inflatable and rigidized anti-space debris and micrometeoroid protection system

Abstract

The invention relates to a protection system that resists space junk and micrometeoroid, rigidifies and space inflates in orbit, which aims at solving the problems of high cost and sheer difficulty for big-size protection screen space-assembly for single or multiple launching, the problems of low folding efficiency, low reliability, small unfolded size in mechanical protection screen unfolding, and the problems of large folding size, inflexible folding, large launching size and small unfolded size of rigid protection screens. Two adjacent layers of rigid space inflating plane frame are connected by the rigid space inflating support vertical tube assembly; protection screens waiting for rigidifying are arranged in the rigid space inflating plane frame; a first and a second inflating pipe are arranged in the rigid space inflating plane frame; vertical inflating pipes are arranged in the rigid space inflating support vertical tube assembly. The protection system has the advantages of simple structure, low cost, high reliability, light weight, high folding efficiency, small folding size, flexible folding and small launching size, which can applied to aircrafts such as satellites, spacecrafts and space stations.

Description

technical field [0001] The invention relates to a protection system against space debris and micrometeoroid. Background technique [0002] There are a large number of high-speed moving (speed ≥ 8km / s) micrometeoroids and space debris in the orbital space of spacecraft such as satellites. The impact of these micrometeoroids and space debris will cause damage, destruction or even failure of the aircraft. It poses a serious threat to the safety of astronauts. For space debris larger than 1 cm, early warning can be given through on-orbit debris monitors, and active protective measures such as avoidance can be taken; for space debris smaller than 1 cm, only passive protective measures can be used. At present, the protection schemes of spacecraft mainly include two kinds of protective screen mechanisms: fixed type and mechanical type. Spacecraft often require a larger-sized protective area and a larger-sized protective screen. Due to the limitation of launch volume and cost, it...
