Problems solved by technology

[0003] The existence of space debris seriously threatens the safety of orbiting spacecraft. The collision between them and the spacecraft will change the performance of the spacecraft, cause damage to the surface components, cause failure of the spacecraft system, and affect the life of the spacecraft.
[0004] At present, the space capture mainly uses the robotic arm, and although the mechanical arm capture is fine in operation, it has high requirements for orbit control and attitude control accuracy, high precision requirements for measuring equipment, short operating distance, high risk, and selective capture. Disadvantages such as location

Embodiment Construction

[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] A method and system for dragging and derailing a timing air-jet tether assembly based on a retractable device of the present invention can be applied to the task of dragging and removing a target after being captured by a space flying net. For space control unstable targets, after the target is captured by the flying net, the mission star will pull the tether to generate tension every once in a while by jetting at a fixed time, so as to drag the target out of orbit. During the non-jet period, the relative distance between the two stars is close, and the tether may be slack. The threshold is designed for the slack degree of the tether. When the slack of the tether exceeds the threshold, the tether retracting device is used to perform the rope retraction operation to ensure that the slack length of the tether is within a certain ...

Abstract

The invention discloses a timing air injection tethered combination dragging deorbiting method and system based on a winding and unwinding device. The timing air injection tethered combination dragging deorbiting method and system can be applied to a dragging removal task after a space flying net captures a target. For a space control unstable target, after the flying net is used for capturing thetarget, a task satellite pulls a tether once at set intervals to generate tension in a fixed-time air injection mode, so that the target is dragged to deorbit. In a non-air-injection time period, therelative distance between two satellites is close, and the tether may loosen; a threshold value is designed for the loosening degree of the tether; when the loosening degree of the tether exceeds thethreshold value, a tether winding and unwinding device is adopted for winding the tether, and it is guaranteed that the loosening length of the tether is within a certain range; when the relative distance between the two satellites is smaller than the threshold value after multiple times of tether winding, the task satellite jets and moves away, and meanwhile, constant small tension is generatedthrough the constant tension generating capacity of the winding and unwinding device.

Description

technical field [0001] The invention relates to a method and system for dragging and derailing an air jet rope assembly based on a retractable device, and belongs to the technical field of dragging and derailing control of a rope assembly. Background technique [0002] GEO orbit has wide application value because of its particularity relative to the ground. It is a very important scarce resource and plays a pivotal role in the space strategy of various space countries. With the increasing demand of various countries for communication, broadcasting, meteorology, navigation and other fields, more and more aircrafts entering this limited space are becoming more and more crowded, and the demand for GEO orbital garbage removal is particularly urgent. [0003] The existence of space debris seriously threatens the safety of orbiting spacecraft. The collision between them and the spacecraft will change the performance of the spacecraft, cause damage to the surface components, cause ...
