摘要:

电子回旋共振离子推力器（ECRIT）以电子的无碰撞加热机制产生等离子体，具有推力范围宽、下限低、可精确控制的特点。本文从原理和工作过程出发，分析了ECRIT对当今空间飞行任务的适用性。围绕这些适用范围，综述了当前原理可行的10cm低推力、2cm微推力ECRIT在不同工质驱动下的研究和应用现状，总结了这些推力器性能的重要特征，分析了制约推力器进一步发展的关键问题。结果表明，ECRIT因为独特的原理和物理过程以及成功的飞行实例，被证明适用于当今深空与近地小行星及引力波探测、微小卫星控制以及地球极低轨道飞行器的阻力补偿。

Abstract:

Electron cyclotron resonance ion thruster （ECRIT） with the mechanism of electron collisionless heating has the thrust property of wide thrust range， lower limit and precise control. According to its principle and operation procedure， the possibility of the thruster applied in space flying mission is analyzed. Around these application scope， the current research and application situation of 10 cm low thrust and 2 cm micro-thrust ECRIT which are feasible in principle under different working medium drive are reviewed. The important performance characteristics of these thrusters are summarized and the key problems that restrict the further development of thrusters are analyzed. The results show that because the special principle， physical procedure and successful space flying example， ECRIT can be suitable to be applied in deep space， near-earth asteroid and gravitational wave detection， micro-satellite control and resistance compensation of satellite flying on low earth orbit.
