摘　　要：热管是航天器热控系统中的一种核心部件,密封性要求高,一旦出现故障,就会造成航天器热控系统的完全失效。针对热管检漏方法原来的技术瓶颈,本文提出了采用基于质谱分析技术的航天器热管密封性能测试方案,建立了测试系统,并对一个热管进行了现场测试,达到了理想的技术指标要求,为将来航天器热管检漏提供了一种可行方法。Heat pipe is a core component for spacecraft thermal control system with high sealing requirement.The malfunction of heat pipe can lead to complete failure of spacecraft thermal control system.Aiming at the technical bottleneck of heat pipe leak detection method,a leak detection of the spacecraft heat pipe based on mass spectrometry analysis technology was proposed with a test system established in this work.Ideal technical index requirement was achieved in the field test,which provides a feasible method for future spacecraft heat pipe leak detection.
