Abstract
This paper analyzes the existing ways of space debris removal, and puts forward a new method by using the space-based light gas gun to remove the debris of scales from 1-10 cm at an attitude of 800 km to 1200 km. Firstly, the projectile acceleration capability of the light gas gun payload of typical parameters is analyzed. Then, based on the idea of pushing the debris into the atmosphere and burning it, the altitude of 800 km circle orbit is selected for the feasibility analysis of coplanar removal of space debris by spaceborne light gas gun ejection. The analysis shows that the viscous projectile with an initial velocity of 1 km/s and a weight of 10 g can well remove the aluminum alloy debris with a mass of 211.95 g. To study the mass range of the debris that can be removed under the scheme, the perigee altitudes of the debris of different masses at the attitude of 800-1200 km after hitting with the projectile are calculated, and the result shows that the maximum mass of the debris is 825 g for 800 km altitude and not less than 500 g for 1200 km altitude, respectively. It proves that the light gas gun projectile has a strong ability to remove debris of the scale of 1-10 cm. Finally, the key techniques of the spacecraft with light gas gun as payload in removing space debris are analyzed.关键词
