空间微小碎片与航天器表面超高速撞击,能够抛射出等离子体,在高充电的航天器表面诱发静电放电,是可能引发航天器异常的一个重要因素.本文利用等离子体驱动微小碎片加速器对充电材料进行超高速(3 km/s)撞击模拟实验,通过观测放电脉冲信号来研究因撞击产生的等离子体诱发的放电,得到较好的实验现象,初步确认了超高速碎片撞击充电材料诱发放电的机理. Space debris and spacecraft surface ultra-high-speed impact, can throw the plasma, the surface of the highly charged spacecraft induced electrostatic discharge is likely to cause anomalies in the spacecraft is an important factor.In this paper, the use of plasma-driven micro-fragment accelerator on the charge material (3 km / s) impact simulation experiment was conducted. By observing the discharge pulse signal to study the plasma-induced discharge caused by impact, a good experimental phenomenon was obtained, and the mechanism of charge-induced discharge triggered by ultra-high speed debris was preliminarily confirmed .
