摘要
空间主反射镜拼接化是未来宇宙观测的发展趋势之一,相比传统的整镜形式空间主镜,拼接主反射镜具有大口径、突破运载器整流罩尺寸限制、高分辨率、轻质和主动调节等特点。根据国内外相关文献和研究项目中主反射镜的拼接化结构形式不同,将可展开拼接式空间主反射镜分为了在轨展开式、在轨拼接式和在轨分布式等三大类,并分别阐述了三种空间拼接主镜的概念、特点与拼接结构形式。按照三种分类形式分别介绍了目前已知的空间拼接式主反射镜项目的研究背景和研究内容。归纳了主反射镜拼接化结构所涉及的关键技术,总结了空间主反射镜拼接化结构设计在拼接精度和面形精度两个方面的研究难点。
Abstract
Space primary mirror splicing technology is one of the development trends of the future cosmic observation. Compared with the traditional space primary mirror, the splicing primary mirror has the advantages of large aperture, breaking the size limitation of carrier fairing, high resolution, light and active adjustment, etc. Based on the literature and research project at home and abroad and the different forms of splicing structures, the deployable splicing space primary mirrors are divided into on-orbit deployed type, on-orbit splicing type and on-orbit distributed typeo. And the concepts, characteristics and splicing structures of these three forms of space splicing mirror are described, respectively. According to the three classification forms, the research backgrounds and research contents of present known splicing primary mirror projects are introduced. This paper summarizes the key technologies involved in the splicing structure of the primary mirror, and summarizes the two research difficulties which are the splicing precision and the face precision as the starting point.
