摘　　要：为了发展基于电推进的大功率空间运输系统,需要开发和验证功率达数十千瓦的电推进系统,深空任务电推进系统优化的比冲要求高达105s。凯尔迪什研究中心(KeRC)正在开发这样的电推进部件。本文概述了35kW离子推力器IT-500及其流动单元FCU-500的验证现状。作为其验证的一部分,完成了IT-500和FCU-500的2000h寿命试验。其中,离子推力器大部分验证条件是:输入功率17.8kW,使用了40kg氙,2018h寿命试验。本文介绍了磁场和离子光学以及石墨格栅开发现状。Using high power space transportation systems equipped with electric propulsion requires devel-opment and qualification of electric thrusters with power equal to tens of kW.The optimal specific impulse of suchsystems designed for deep space missions should be very high(up to 105 s).Elements for electric propulsion sys-tems are developing at Keldysh Research Center(KeRC).This paper presents qualification status of IT-50035 kW ion thruster and FCU-500 flow control unit.2000 hours lifetime test of the IT-500 and FCU-500 was per-formed as a part of qualification.The ion thruster accomplished 2018 hours of operation for the most part at inputpower of 17.8 kW,utilized 40 kg of xenon.Magnetic field and ion optics improvement and graphite grids develop-ment status are also described in this paper.
