摘要
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.
The development of all-electric propulsion platform, the need of different space missions and space constraints make it necessary to develop the multi-mode operation Hall Thruster. Based on the de- mand analysis of all-electric propulsion platform for propeller, we discuss the key technologies. It shows that the bottleneck problems are sufficient ionization of working medium, thermal load of thruster and plum focalization under the high specific mode. The development directions of the multi-mode operation Hall thruster are cathode design technology in wide scope of work condition and nest technology. These need the technical breakthrough about development of the multi-mode Hall thruster in continuous adjustment of work mode, high specific impulse and large total specific impulse.
