国外多模式霍尔电推进发展概况及启示

多模式霍尔电推进具有多个工作模式,调节能力强,相对于20世纪80年代以来广泛应用的只有一个工作模式的霍尔电推进器,其优势明显,能很好地适应诸如GEO卫星轨道转移和在轨位置保持,以及深空探测器和空间运输平台的主推进等多种任务,因此得到了广泛研究和应用.国外多模式霍尔电推进发展现状和趋势对我国多模式霍尔电推进的发展具有重要的启示作用.针对我国航天器对电推进的迫切任务需求,定量分析应用多模式霍尔电推进的收益,提出我国多模式霍尔电推进发展的建议.

Development overview of foreign multimode Hall electric propulsion technology and corresponding inspiration

Multimode Hall electric propulsion with good throttle capability can operate with different modes, and has obvious advantages compared to the one-mode Hall electric propulsion which has been used extensively since 1980s. Multimode Hall electric propulsion is studied and used widely because of its good adaptability to many kinds of missions such as orbit transferring and on-orbit station keeping of GEO satellites, primary propulsion of deep space crafts and spaceships, etc. The current status and development trends of foreign multimode Hall electric propulsion result in an important inspiration to the development of domestic multimode Hall electric propulsion. According to the urgent demand of electric propulsion for domestic spacecrafts, the gains of applying multimode Hall electric propulsion is analyzed quantitatively, and the development suggestion of domestic multimode Hall electric propulsion is put forward.
