摘要
亚太6E卫星是国产首颗全电推通信卫星,也是全球首颗从低地球轨道到地球同步轨道实现全自主轨道转移的通信卫星.亚太6E卫星首先利用独立推进舱的化学推进系统实现快速轨道提升,接着卫星与独立推进舱分离,最终由卫星的全电推进系统完成后续轨道转移任务.星间分离是决定任务成败的关键,首先介绍亚太6E卫星星间连接与分离机构设计,接着依次对连接应力裕度、分离过程近场安全与远场安全开展分析,系统阐述全电推进平台搭配低成本运载火箭工程实践的经验与成果,对后续项目具有一定的参考意义.
Abstract
AP-6E satellite is the first domestic all-electric communication satellite,which is also the first communication satellite in the world to realize the autonomous orbit transfer from low earth orbit to geosynchronous orbit.The separable propulsion segment is utilized to realize the rapid orbit transfer via the chemical propulsion system,then the segment is separated and de-orbited,finally the remaining tasks of the satellite are preformed solely by the electric propulsion system.Therefore,the inter-satellite separation is the key to the success of this mission.The design of the connection and separation mechanism of AP-6E is introduced,and the stress margin of connection and the near-field and far-field safeties of separation process analyzed in order to systematically expound the experience of the engineering practice of the all-electric propulsion platform carried by the low-cost launch vehicle,which is of certain significance for the subsequent projects.
