- 空心阴极是电推进系统可靠性和工作寿命关键部件,空心阴极产品的研制在很大程度上依赖于阴极试验技术的支持。在介绍空心阴极试验分类和试验设备的基础上,从性能试验、验收和鉴定试验及寿命验证试验等方面讨论了电推进系统空心阴极的产品试验技术。
- Abstract:
- A hollow cathode is a key assembly for reliability and lifetime of an electric propulsion system. The development of a hollow cathode product depends on test technology to a large degree. Based on an introduction to the test classification and test facility of the hollow cathode, the test technology of a hollow cathode product applicable to electric propulsion system is discussed from performance test, acceptance test, qualification test and lifetime test respectively. It is concluded that the most suitable method of lifetime assessment of a hollow cathode product for either long lifetime or high power electric propulsion system is a combination of practical test and theoretical model.
