在空间环境运行的航天器存在表面充电现象,而航天器表面充电引发的静电放电是导致航天器异常及故障的重要原因之一。因此,在航天器设计和应用中,必须对航天器表面电位采取必要的控制和防护措施。文章介绍了用脉冲等离子体源进行航天器表面充电电位主动控制的研究。通过模拟实验和实验数据分析,证实了用脉冲等离子体源能有效地控制航天器表面充电的电位,阐明了脉冲等离子体控制表面电位的原理和控制特点;提出了用控制效率或等效电阻这一参数,解释各种因素对表面电位控制效果的影响。实验证明,对航天器表面电位进行主动控制是一种行之有效的方法。

There is surface charging when a spacecraft operates in the space environment.The electrostatic discharge induced by spacecraft surface charging is an important cause of spacecraft anomalies and failures.Therefore,we must take measures to control the surface potential of the spacecraft when we design and apply spacecraft.This paper presents the investigation of the active control of spacecraft surface charging potential by using a pulsed plasma source.Through simulation experiments and theoretical analysis,the feasibility and feature of using pulsed plasma source to control spacecraft surface potential are demonstrated,its control principle can be elucidated,and the control efficiency η or equivalent resistance R to explain the influence of various factors on surface potential control effect is also provided.It is proved that the active control of spacecraft surface potential is one of effective methods of spacecraft surface potential control.
