Small satellite formation design method for realizing space debris racemization by utilizing eddy current effect

Abstract

The invention discloses a small satellite formation design method for realizing space debris racemization by utilizing an eddy current effect. Small satellites launched by a spacecraft platform are formed into groups according to the position of debris with respect to the spacecraft platform and external dimensions of the debris. Four of the small satellites are released by the spacecraft platform to around the target debris, and the small satellites unwind energized solenoid coils and solar panels and form a natural circular or elliptical formation centered on the target debris by controlling positions and velocities of the small satellites during the release. Through the attitude control, the energized solenoid coils of the small satellites are facing right towards the target debris, a magnetic field is generated to the energized solenoid coils, the solar panels supply the required power to racemase the debris, the angular velocity of the rolling of the debris is reduced, and quick racemization of the high-speed rotating space debris is realized. By the method, as the multiple small satellites carry the energized solenoid coils, the strength of the magnetic field is increased, and the rotational angular velocity of the high-speed rotating debris can be rapidly reduced.

Description

【Technical field】 [0001] The invention belongs to the field of spaceflight technology, and relates to a small satellite formation design method for realizing derotation of space debris by using eddy current effect. 【Background technique】 [0002] With the continuous development of human spaceflight activities, the spatial density of space debris has posed a threat to the safety of spacecraft, especially in low-Earth orbit, where the density of debris is higher, and its number is still increasing rapidly. happens sometimes. The growing amount of debris is making the orbital space around Earth increasingly crowded. In addition, the collisions between existing debris and debris and between debris and satellites in space will continue, and more debris will be generated, thereby causing a chain reaction. Therefore, in recent years, major aerospace countries and international research institutions have reached a general consensus that only implementing debris mitigation is far f...

Problems solved by technology

But this method also has many limitations, for example, the magnetic field strength of the magnetic field generated by the spacecraft carrying a single helicoid is low, making the derotation effect too poor, and the derotation time is too long; The external dimension requirements of the are limited and cannot be changed according to the size of the fragments
