Space debris derotation device and method for changing moment of inertia distribution by using adsorption mass block

Abstract

The invention discloses a space debris despinning device and method for changing moment of inertia distribution by an adsorption mass block. The device comprises a service spacecraft main body installed with a solar panel. An absorbent mass block is positioned on top of that ejection device and can be ejected. Each surface of the adsorption mass is uniformly distributed with an adsorption assemblyfor connection with a target. The angular acceleration and angular velocity of the target are changed by changing the moment of inertia distribution of the target by firing the absorptive mass at a specific position on the target, so as to realize the fast elimination of the rotation of the target while minimizing the influence on the service spacecraft.

Description

technical field [0001] The invention relates to aerospace technology, in particular to a space debris derotation device and method for changing the distribution of rotational inertia by using an adsorption mass block. Background technique [0002] The exploration activities of human beings in outer space are gradually increasing, which brings benefits and also has a lasting and far-reaching impact on the space environment. The remaining rocket stages, failed satellites, spacecraft mission discards, spacecraft disintegration and collision derivatives in space A large number of space debris such as space debris have posed a huge threat to the development of human spaceflight. Therefore, the active removal technology of space debris has become a research hotspot in the aerospace field. The primary key to the active removal of space debris is the implementation of on-orbit capture, and most of the space debris are non-cooperative targets. Since the target has lost the ability t...

Problems solved by technology

Contact derotation methods based on deceleration brushes or mechanical pulses are suitable for rapid derotation of large-mass targets, but have a great impact on the supporting service spacecraft, and require high control capabilities for the service spacecraft during the derotation process; Using gas impact, electrostatic force, electromagnetic force, laser and other non-contact forces for derotation can effectively reduce the risk of collision, and attenuate the target three-axis speed outside the safe distance, but the derotation process lasts for a long time
