离子推力器流率调节热节流器性能测试

PERFORMANCES TEST OF THE THERMAL THROTTLEERS FOR ION THRUSTERS FLOW REGULATED

摘要: 离子推力器工作时的推进剂氙气流率很小,一般在0.1～2.0 mg/s之间,对氙气流率的稳定性要求也很高,所以需要对微小流率控制热节流器的性能特性和长期工作稳定性进行测定和有效评价。从测试装置、测试方法、测试过程、测试结果分析与评价等方面介绍了热节流器的性能测试与研究情况。

Abstract: Propellant flow rate is very low for ion thrusters,commonly between 0.1～2.0mg/s,and its high stability is required.It is significant that the test and evaluation of the performances and longtime working stability of thermal throttleers.In this paper,the test facility,the test methods,the test process and the estimates to test results are presented.
