不同空间任务和约束条件对霍尔推力器提出了多模式工作的需求,通过对全电推进卫星对推进器的需求分析,论述霍尔推力器多模式工作涉及的关键技术.分析表明,高比冲模式下工质充分电离、推力器热负荷、羽流聚焦是技术瓶颈问题,多模式宽范围工作的阴极设计技术、多环/成组技术是霍尔推力器发展的重要研究方向,多模式霍尔推力器未来的发展需要在模式连续可调、大总冲和高比冲方向取得技术性突破.
Different space tasks and constraints on the Hall thruster put forward the requirements of multi-mode work, through the analysis of all-electric propulsion thruster needs, discusses the Hall thruster multi-mode work involved in the key technology analysis shows that the high ratio The full ionization of working fluid under the red mode, the thermal load of the thruster and the focusing of the plume are the bottlenecks of the technology. The cathodic design technique of multi-mode and wide-range work and the multi-ring / group technology are the important research directions for the development of Hall thruster. The future development of Hall Thruster need to be continuously adjustable mode, the total Chong and high specific direction made a breakthrough.
