一、前言在今后相当长一个时期内,太阳电池阵将仍然是卫星长期运行必不可少的能源,而展开式定向太阳电池阵(以下简称太阳阵)结构是卫星结构研制中一个比较关键的项目。由于航天事业的迅速发展,卫星所需功率越来越高,这就要求太阳阵的尺寸更大,结构质量更轻。国外太阳阵技术已发展到第三代。结构形式繁多,至今不下几十种。但按基板形式的不 I. Introduction In a considerable period of time to come, the solar array will still be an indispensable source of energy for the long-term operation of satellites. However, the structure of an expanded directional solar array (hereinafter referred to as the solar array) is a key project in the development of satellite structures . Due to the rapid development of space undertakings, the required power of satellites is getting higher and higher, which requires the solar array to be larger in size and lighter in structure. Foreign solar array technology has been developed to the third generation. A wide range of structures, so far no less than dozens of species. But not in the form of substrate
