国外卫星推进技术发展现状与未来20年发展趋势

新形势下航天技术的发展对推进技术提出了更高的要求,无论在技术的广度和深度上都是前所未有的,如15年以上静止轨道卫星和8年以上低轨道卫星对高性能长寿命推进系统的要求、电推进技术的应用、微小卫星轨道保持的应用和深空探测对先进推进技术的依赖等。本文从先进化学推进技术、电推进技术、微推进技术和新概念推进技术4个方面分析了国外卫星推进技术的发展状况,总结了未来20年卫星推进技术的发展趋势,给出了对我国今后技术发展的启示。

Current Situation and Developing Direction of Foreign Satellite Propulsion Technology in the Next 20 Years

With the development of space technology under the new decade,geostationary satellites with 15-year lifetime and low-orbit satellites with over 8-year lifetime require high performance propulsion system.In this paper,based on analysis of foreign advanced chemical propulsion technology,electric propulsion technology,micro-propulsion technology and new concept propulsion technology,the developing status of foreign satellite propulsion technology is illustrated;the developing direction of satellite propulsion ...
