航天器内部构型复杂性因素对于深层充放电防护影响研究

The spacecraft deep charging has become a major concern one which may reduce the reliability of spacecraft and disturb the service provided by spacecraft. The researching of characteristics and models about spacecraft deep charging is the requirement of avoiding the spacecraft deep charging. The spacecraft deep charging may be affected by some factors, such as conductor configuration, conductor surface condition, whatever the conductor is grounded or not, and surrounding space electromagnetic. .In this project, the general methodology of the project will be provided firstly; and then, the spacecraft charging models, numerical methods and experiment proposal will be developed; finally, some experiments will be performed, the models and numerical methods will be modified according to result of experiments..After this project, the characteristics and models of components configuration and electromagnet coupling will be achieved. The advise to prevent space deep charging will be proposed. The fundamental problems of avoiding spacecraft deep charging are expected to be solved gradually.
