Six traction device space debris net capture system

Abstract

The present invention proposes a space debris net capture system with six traction devices, which adopts the method of first-stage launch and mass block synchronous launch, and the concentric circle rope net is folded and stored, including: launch subsystem, consisting of a launcher, a net cabin, and a buffer device It is composed of a tether tension control device; the flying net subsystem is composed of a rope net and a mass block, wherein the transmitter is used to push the mass block to move according to the preset launch angle when approaching the predetermined distance of the target and drive the rope net from the net cabin. Pull out while unfolding and reach the fully unfolded state, so as to net the target after reaching the target position. The quality block is used to pull the rope net out and tighten the net mouth to complete the target capture. The number of mass blocks is at least three and passed through The optimization analysis uses six mass blocks, the tether tension control device is connected to the flying net subsystem and the target is connected to the target through the rope net to pull the captured target off the track. The rope net is encapsulated in the net cabin in a concentric circle packaging method And used to create enough coverage space to completely surround the target.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and relates to a net-catching system for space debris with six traction devices, which adopts the mode of first-stage launch and mass block synchronous launch, and the concentric circle rope net is folded and stored, and can be used for space debris (abandoned satellites, orbital garbage) It can also be used for the capture and on-orbit service of other non-cooperative targets (meteorites, asteroids, etc.). Background technique [0002] Space debris originated from human spaceflight activities. With the rapid development of space technology, the number of space debris has also increased rapidly. According to the data released by the US Space Monitoring Network, as of January 2012, the number of space objects that can be monitored and recorded There are nearly 22,000 of them, more than 90% of which are space debris, and its potential collision risk increasingly threatens the safety of spacecraf...

AI Technical Summary

Problems solved by technology

[0005] 1) When the flying net is launched, the protective cover will be ejected first, forming additional space debris, and may collide with the capture target to produce more debris;

[0006] 2) Using the ejection and pulling method of four mass blocks, the size distribution of the expanded mesh size of the flying net is not uniform enough, and the covering performance of the target is not good;

[0007] 3) The four mass blocks adopt the method of spring ejection, it is difficult to precisely control the synchronization of the launch, which may cause the center of the rope net to be biased and unable to cover the target

[0012] 2) The second-stage deployment process adopts the four-mass synchronous launch method, and the mesh size distribution of the flying net is not uniform enough, and the target coating performance is not good
