Embodiment Construction

[0032] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings. These embodiments are only used to illustrate the present invention, and are not intended to limit the protection scope of the present invention.

[0033] Such as figure 1 As shown, the present invention provides a method of towing and de-orbiting based on the tether retractable device 3, wherein, during the entire dragging process to the target star 1, the output of the tether retractable device 3 on the mission star 2 is constant Keep the tether 4 tensioned between the mission star 2 and the target star 1; specifically include the following steps:

[0034] Step 1: Establish the center-of-mass dynamic equations and attitude dynamic equations of the mission star 2 and the target star 1, as well as the dynamic model of the tether 4.

[0035] (1) The center-of-mass dynamic equations of mission star 2 and target star 1 in the geocentric inertia...

Abstract

The invention discloses a dragging off-orbit method based on a rope retractable device. During the entire dragging process to the target star, the rope retractable device on the mission star is used to output a constant small tension to keep connected to the mission star. The tether tension between the target star and the target star; specifically includes the following steps: Step 1: Establish the center-of-mass dynamic equation and attitude dynamic equation of the mission star and the target star, as well as the dynamic model of the tether; Step 2: Take the dragging direction Perform assembly attitude maneuver for the target; Step 3: The mission star drags the target star out of orbit through the tether, and controls the attitude of the assembly during the period to make it face the dragging direction. The invention is based on the dragging off-track method of the rope retractable device, and uses the rope retractable device to generate a constant small tension, which not only ensures that the tether is tensioned without the risk of winding, but also ensures that the tension of the tether will not be too large without the risk of breakage, and the grasping The target is dragged stably and safely to the grave track.

Description

technical field [0001] The invention relates to a dragging and derailing control technology of a rope assembly, in particular to a dragging and derailing method based on a rope retractable device. Background technique [0002] Geostationary Earth Orbit (GEO) has wide application value because of its relative ground-stationary particularity. 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 failure of the sp...
