| 摘要: |
| 远征上面级研制自2009年开始，经过6年研制工作后，2015年3月30日成功首飞，至今已发展形成了适应不同发射需求的远征系列上面级，累计发射近20次，将40余颗大型航天器精准送入中轨道(MEO)、地球同步轨道(GEO)、倾斜地球同步轨道(IGSO)、太阳同步轨道(SSO)、再入轨道等多种空间轨道，实现了空间运输系统跨越式发展。对10年来远征上面级的研制技术发展进行了回顾，分析了其技术优势和关键技术研究情况，并对我国上面级的后续发展提出建议。 |

| Abstract: |
| The research on Yuanzheng upper stage started from 2009,and 6 years later,the first launch recorded on March 30th in 2015. So far, the Yuanzheng upper stage has developed into a series. About 20 missions have been successfully completed by Yuanzheng series, and more than 40 large-scale spacecrafts have been sent into MEO/GEO/IGSO/SSO or reentry orbit in high precision. It ensures the striding development of space transportation system.This paper reviews the development and progress of Yuanzheng upper stage technology in past 10 years, analyzes the advantages and the main key technologies in the process. Finally, the subsequent development suggestions of upper stage technology in China are put forward. |
