氙离子火箭发动机补偿栅极设计

DESIGN OF COMPENSATION DOME GRIDS ON XENON ION THRUSTER

摘要: 离子光学系统是离子火箭发动机推力器中装配要求最严格的部件之一,其性能的好坏直接影响整个推力器的性能。栅极是离子光学系统的主要组件,作者主要针对大面积球面栅的束发散较大的问题,对栅极进行了补偿设计,目的是减小束发散角。

Abstract: Ion optic system（IOS）is one of the critical subassembly of Ion thruster（IT）.It’s performance directly affect to the IT operation performance.Grids are dominating component of the IOS.IT with dome grids are subject to significant thrust losses due to the divergence of the ion beam.A method of compensation dome grids was designed to decrease the di-vergence of the ion beam.
