Space fragment and micrometeoroid impact resistant protection mechanism capable of inflating and expanding on rails

Abstract

A defense mechanism which can be charged and unfolded on track and is capable of resisting the impact from space debris and micrometeoroid relates to a defense mechanism for resisting the impact from space debris and micrometeoroid, aiming at solving the problems of high cost and big difficulty in large size defense screens assembled in space for one or more launches and the problems of low folding efficiency, low reliability and small size after being unfolded on mechanically unfolded defense screens. Two adjacent layers of plane frames which can be hardened and can be unfolded by charging are connected through a support upright pipe assembly which can be unfolded by charging, and defense screens are arranged in the plane frames which can be hardened and can be unfolded by charging and are connected with the plane frames which can be hardened and can be unfolded by charging; horizontal leads and air inlet pipes are arranged inside the plane frames which can be hardened and can be unfolded by charging; vertical parallel leads and charging pipes are arranged inside the support upright pipe assembly which can be unfolded by charging; the horizontal leads are connected with the vertical parallel leads; the first charging pipe and the second charging pipe are communicated with short and long support pipes which can be hardened and can be unfolded by charging; the vertical chargingpipes are communicated with the support upright pipes which can be hardened and can be unfolded by charging. The defense mechanism is good in defending effect, high in reliability, light in weight, high in folding efficiency and low in cost.

Description

technical field [0001] The invention relates to a protection mechanism against space debris and micrometeoroid impact. 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 an...

AI Technical Summary

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-shot or multiple launches, and the low folding efficiency and low deployment reliability of mechanically unfolded protective screens. , the small volume after deployment, and the difficulty of constructing more than three or more layers of multi-layer protection, and then provide a protection mechanism that can be inflated and deployed in orbit to resist space debris and micrometeoroid impacts
