摘　　要：介绍了霍尔推力器原理的基础上,推导分析了霍尔推力器推力的影响因素,总结了改变其推力的主要方法。概述了微牛级、毫牛级和牛级等不同推力级适用的航天任务类型,按照3个级别对国内外霍尔推力器型号进行了分类,分别对3个推力级各系列型号的发展及趋势进行了梳理与分析。对各推力级霍尔推力器发展的关键技术进行了展望。针对其中的技术瓶颈与发展趋势进行了总结分析。全面、系统地针对各推力级霍尔推力器进行了综述。结果表明:毫牛级发展最为成熟的推力级,而随着航天任务类型逐渐丰富,微牛级和牛级霍尔推力器发展潜力愈发突出;研究结果提出了霍尔推进器应提升整体性能、扩展推力覆盖范围,强化多模式工作能力,发展空心阴极以及探究不同推进剂等建议。该研究结果对于霍尔电推进的进一步发展具有参考价值。Based on the introduction of the principle of Hall thruster,the influencing factors of Hall thruster thrust were deduced and analyzed,summarizing how to change Hall thruster thrust.The types of space missions applicable to different thrust levels,such asμN-level level,mN-level and N-level were summarized.The models of Hall thrusters at home and abroad were classified according to three levels,and the development and trend of each series of models of the three thrust levels were sorted out and analyzed respectively.The technical bottleneck and development trend were summarized and analyzed.Hall thrusters of various thrust stages were comprehensively and systematically reviewed.The results indicated that the mN-level was the most mature.With more abundant types of space missions,theμN-level level and N-level Hall thrusters had considerable development potential.The key technologies for the development of Hall Thrusters in each thrust stage were prospected.The results suggested that Hall Thrusters should improve the overall performance,expand the thrust coverage,strengthen the multi-mode working ability,develop hollow cathode and explore different propellants,thus providing a reference for the further development of Hall electric propulsion.
