                              美国制造全电推进商业通信卫星 开启小而美的传奇

                              2015-02-27 09:56:20

                              在不久前揭晓的2015全球十大航天新闻中,“世界首批全电推进商业通信卫星进入太空”位列其中。由美国制造的世界首批全电推进商业通信卫星——亚洲广播卫星—3A和欧洲通信卫星—115西B去年初成功发射,被认为是全电推进技术实现成熟应用的标志。那么,什么是全电推进?它对卫星产业的发展到底有多大魔力呢?

                              总之,电推进系统可广泛用于地球静止轨道卫星位置保持和轨道转移、空间探测器和载人深空探测的主推进、低轨卫星的轨道维持等许多方面。目前,电推进系统的电能是由太阳能经转换装置获得的,所以功率有限,未来有望由核能提供,从而研制出大功率的电推进系统,用于打造核动力载人火星飞船,从而大大缩短飞往火星的时间。(庞之浩)
