离子推进器热特性测试与分析

摘要

对离子推进器工作状态的热特性进行了测试与分析.测试分析结果表明:离子推进器工作时产生的热量主要以热传导和热辐射向周围环境传递,通过安装环传导到航天器的热量较少,不会对航天器产生影响.热辐射主要向空间辐射,不会对航天器造成热影响.%The thermal characteristic was tested and analyzed far the operating ion thruster. The result indicating; Heat was mostly transferred to ambience through conduction and radiation in the operating ion thruster. Less heat was transferred to spacecraft by fix flange, so it did not influence spacecraft. Radiant heat was mostly transferred to space, and did not influence spacecraft too.
