Six-traction device space debris net capture system

Abstract

The invention provides a six-traction device space debris net capture system which adopts level-1 launch and mass blocks synchronization launch and concentric circles rope net folding and receiving. The system comprises a launch subsystem which is composed of a launcher, a net hold, a cushioning device and a tether tension control device; a fly net subsystem which is composed of a rope net and mass blocks; the launcher is used for pushing the mass blocks at a predetermined distance from a target at a predetermined angle and to drive the rope net be pulled from the center of the net hold while unfolding to a fully unfolded state to capture the target after reaching the target location; the mass blocks are used for dragging the rope net so that the rope net is pulled out and unfolded and the net opening is tightened up to complete capture of the target; the number of the mass blocks is at least three and six mass blocks are adopted through optimized analysis; the tether tension control device is connected with the fly net subsystem and with the target through the rope net to pull the captured target off the track; the rope net is encapsulated in the net hold in a concentric circles package and is used to form sufficient coverage 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
