摘要
空心阴极是电推进系统可靠性和工作寿命关键部件,空心阴极研制在很大程度上依赖于阴极试验技术的支持。本文从空心阴极的试验分类、试验设备、试验技术等方面介绍了电推进系统应用空心阴极的研制试验技术。
Hollow cathodes are key assemblies of reliability and life for an electric propulsion system,and their developments are strongly depended on a series of tests.In this paper,the development tests of a hollow cathode for ion or hall thruster was presented within three aspects,including test kinds,test facilities,and test technologies,respectively.
