| 摘 要： | 栅极系统电子返流是离子推力器寿命的主要失效模式之一。以20 cm Xe离子推力器地面运行测试数据为基础,结合离子推力器栅极系统电子返流失效机理,预测了离子推力器在地面测试环境中和空间飞行环境中栅极系统电子返流对寿命的影响。预测结果表明:20 cm Xe离子推力器在地面试验环境中和空间飞行环境中的预期寿命分别为6 600 h和17 000 h。

| Abstract: | Grids system electron backstreaming is one of key failure models for ion thruster.This paper that is based on the 20 cm Xe ion thruster operation data and considered the failure mechanism of ion thruster grids system electron backsteraming,evaluate the effect of electron backstreaming on ion thruster for operating on ground and space.The result indicated that the life of 20 cm Xe ion thruster while appear electron backstreaming are 6 600 h and 17 000 h for operating on ground and space respectively. |
