我国航天器带电技术研究进展

Review of spacecraft charging technology studies in China

航天器与空间带电粒子环境相互作用引起的带电现象是其在轨发生故障和异常的重要因素。近年来,随着航天器性能的提升和技术发展,航天器带电技术研究的范围也大大扩展。文章简要回顾了我国航天器带电技术发展的历史,并从理论研究、地面模拟试验、数值模拟和带电防护等方面介绍国内航天器带电技术研究的进展。

The spacecraft charging induced by the interaction of a spacecraft with a charged particle environment is an important phenomena, which is harmful to the reliable operation of the spacecraft in orbit. With the development of the first communication satellite in China, the studies of spacecraft charging technology started. It has a long history of more than 30 years. These studies have played a very important role to ensure a high reliability of spacecraft. This paper reviews the history and main results of studies of spacecraft charging technology in China, including theoretical studies, charging protection technologies, charging and discharging test facilities and simulation softwares.
