航天器表面充放电原理研究

全面介绍了航天器与空间离子发生表面充放电效应的原理,将航天器表面充电简化成电流平衡方程,通过确定电流的表达解析式来确定表面各点的电流变化,把航天器表面划分成若干个等效电路,更加直观地了解了航天器充电过程。从航天器表面充放电现象发现了充放电带来的危害,并详细从航天器构件接地方式、航天器结构设计、航天器电路电磁防护等方面阐述了航天器表面带电防护的方法。

Charge and Discharge Principle ofSpacecraft Surface

Charge and discharge principle of spacecraft surface was introduced.The spacecraft surface charging was simplified into current balance equation;by determining the current expression formula,the current variation of each point on the surface was determined.The spacecraft surface divided into several equivalent circuits is more intuitive to understand the spacecraft charging process.The methods of spacecraft surface charging protection were introduced from the aspects of grounding mode,structural design,and electromagnetic protection.
