A space debris tether drag derotation and cleaning method

Abstract

The invention discloses a space debris rope system dragging despinning and removal method, relates to space debris despinning and removal methods and belongs to the technical field of spaceflight. By the adoption of the method, a trailer spacecraft is launched into an orbit, so that the rendezvous with debris is finished; a trailer is connected with the debris through multiple tying ropes; a dynamical model is established, a control law is designed to adjust the nominal rope length of each tying rope to change the tension of the tying ropes, despinning of the debris is achieved through the cooperation of the multiple tying ropes, the situation that the tying ropes are cut and broken through protruding components on the debris is avoided, and the stability and the redundancy of a rope system trailer system are improved; and a trailer engine is used for ignition, reverse dragging force is applied, the space debris is pulled into the atmosphere to be burnt, and therefore debris removal is achieved. By the adoption of the method, despinning of the space debris can be achieved, the situation that the tying ropes are cut and broken through the protruding components on the debris is avoided, and the stability of the system is improved; and in addition, the redundancy of the tying ropes is improved by increasing the number of the tying ropes. The method can be used for space debris despinning and removal and can also be used for despinning of and control over other non-cooperative targets.

Description

technical field [0001] The invention relates to a method for derotation and cleaning of space debris, in particular to a method for derotation and cleaning of space debris using a rope dragging method, which belongs to the field of aerospace technology and can be used for space debris (abandoned satellites, rocket upper stages, explosions) It can also be used for the racemization and control of other non-cooperative targets. Background technique [0002] Since the successful launch of the first artificial Earth satellite by the former Soviet Union in 1957, the amount of space debris has been accompanied by a rapid and sustained increase in human spaceflight activities. According to the latest report released by NASA's Orbital Debris Program Office, as of April 6, 2016, 17,385 large orbiting targets have been monitored, including 4,041 payloads and 13,344 rocket bodies, and debris larger than 1 cm in diameter The total number is estimated to be in the order of millions, main...

Problems solved by technology

However, there are obvious disadvantages in the prior art: generally speaking, space debris is in a rotating state, and the protruding parts on the debris (such as solar panels, etc.) may be entangled and cut with the tether, causing the protruding parts to fall off or the tether to break, thereby Cause the cleanup task to fail, and even cause more debris to be generated

The single-rope tethered trailer system has the problem of low redundancy
