空间站核心舱柔性太阳翼设计与验证

Design and Verification of Flexible Solar Array on Core Module of Space Station

柔性太阳翼国内首次在中国空间站核心舱成功应用,是平台及有效载荷正常运行的唯一发电装置,其成败直接影响航天器任务成败,是空间站系统最复杂、难度最大的机电产品之一。介绍了柔性太阳翼系统的构成和工作原理,对其技术特点及关键技术进行了分析,并剖析了地面及在轨飞行验证情况。

Flexible solar array(FSA)has been first successfully applied in core module of China space station.FSA is the only power source of the platform and payloads in China space station.Thus,the success of the whole space mission depends heavily on the proper functioning of FSA.As the largest and most complex solar array in China aerospace history,FSA is one of the most complex and challenging electromechanical sub-systems in China space station.This article describes the system composition and working principle of FSA,and then analyses the basic characteristics and key technologies,lastly the ground experiment and on-orbit performances are presented.
