一种地球静止轨道空间碎片主动清除方式

An active removal method of space debris in geostationary orbit

首先讨论国内外对空间碎片主动清除技术的研究进展,分析空间碎片清除平台的功能要求。然后提出一种静止轨道空间碎片主动清除方式,即通过空间碎片清除平台发射出粘性弹丸与目标空间碎片进行非弹性碰撞,使空间碎片获得一定的速度增量,进而被推离原轨道。其次,对粘性弹丸的轨道转移过程进行建模,推导出拦截时间、弹丸飞行距离等要素与姿态俯仰角的关系。最后,利用Simulink对弹丸的轨道转移过程进行了仿真,分析拦截时间t,飞行轨迹长度S与弹丸俯仰角(弹丸出射速度与碎片清除平台速度的夹角)的关系。

An active removal method of space debris in the geostationary orbit is proposed after discussing the research progress of active removal technology of space debris at home and abroad,and analyzing the functional requirements of the space debris removal platform.The viscous projectile is launched from the space debris removal platform to make inelastic collision with the debris in target space,so that the space debris can obtain a certain velocity increment and be pushed away from the original orbit.The orbit transfer process of the viscous projectile is modeled,and the relationship of interception time and projectile flight distance to the pitch angle of the attitude is deduced.The orbit transfer process of the projectile is simulated by Simulink.The relationship of the interception time t and flight trajectory length S with the pitch angle of the projectile(the included angle between the ejected velocity of the projectile and the velocity of the debris removal platform)is analyzed.
