双组元推进剂质谱检测实验研究

The Experimental Study of Double Component Propellant with Mass Spectrometer Method

推进剂泄漏检测技术是关系到航天器正常运行和安全发射的关键技术之一。采用燃烧剂、氧化剂的双组元推进剂是航天器推进系统经常选用的燃料。质谱检测技术具有同时检测环境中这两种微量成分而不相互干扰的优点。文章简述了双组元推进剂的质谱检测装置， 给出对甲基肼、四氧化二氮的质谱实验研究方法及检测结果。

The propellant leak detection technology is one of the key technologies for spacecrafts launch and operation.Both components such as MMH and MON 1 have been adopted in the propulsion system.The mass spectrometer technology has the ability to detect them in the mean time.In the paper,the detection equipment is introduced briefly,and the experiment results of MMH and MON 1 are also given.
