Abstract

A multi-layer cavity-type aeration for expansion protection mechanism relates to an aeration for expansion protection mechanism, which aims at solving the problems that a monolayer protection screen can not effectively avoid the damage caused by the collision from the space chippy fraction, and a mechanism-typed expansion protection mechanism has low folding efficiency, low expansion reliability and a small volume after expansion. Parts of the periphery of the adjacent two protection screens cling together to form a cavity-type aeration for expansion protection screen to be rigidified, which is connected with an aeration supporting frame to be rigidified; a main inflation pipe is arranged in the cavity-type aeration for expansion protection screen to be rigidified and communicated with anair-discharging pipe; the lower end of the aeration supporting frame to be rigidified is provided with an aeration supporting pipe to be rigidified, which is communicated with the inflation pipe of asupporting pipe; two ends of an aeration bent pipe are communicated with an aeration pipe to be rigidified and the aeration supporting pipe to be rigidified. The invention can avoid the damage causedby the collision from the space chippy fraction, and has the advantages of high folding efficiency, high expansion reliability and a large volume after expansion.

Description

technical field [0001] The invention relates to an inflatable deployment protection mechanism, in particular to a protection mechanism for astronauts and spacecraft against impact damage from space debris and micrometeoroids. Background technique [0002] All kinds of spacecraft in low earth orbit and astronauts going out for spacewalks are vulnerable to ultra-high-speed impacts from micrometeoroids and space debris. These impacts damage the key systems of the spacecraft flight, leading to catastrophic failure of the spacecraft, threatening the safety of the astronauts and the normal operation of the spacecraft. Therefore, it is necessary to use protective mechanisms to protect the key parts of the spacecraft and the astronauts. very necessary. It is difficult for a single-layer protective screen to effectively protect against space debris impact damage; mechanically deployed protective mechanisms have disadvantages such as low folding efficiency, large launch volume, low d...
