The invention relates to a flexible solar cell array unfolded step by step. The flexible solar cell array is composed of an upper storage box, a lower storage box, a tensioning mechanism, a guide mechanism, a pressing and releasing mechanism, a flexible solar cell panel, a secondary unlocking device and the like. The flexible solar cell array is used as a power generation device of a spacecraft, can bear a mechanical environment of a spacecraft launching section, has force energy for keeping two unfolding lengths and structural rigidity under the cooperation of an external unfolding mechanism,and meets a requirement of orbital transfer at an initial stage of orbital injection of a spacecraft, the requirement of a butt joint stage for a unfolding fundamental frequency of a solar cell arrayand the requirement of long-term on-orbit operation for generating power of the solar cell array at the same time.
本发明涉及一种分步展开的柔性太阳电池阵。该柔性太阳电池阵由上收纳箱、下收纳箱、张紧机构、导向机构、压紧释放机构、柔性太阳电池板、二次解锁装置等组成。该柔性太阳电池阵作为航天器的发电装置,可承受航天器发射段力学环境,在外部的展开机构配合下具有保持2种展开长度及结构刚度的力能,同时满足航天器入轨初期的变轨、对接阶段对太阳电池阵展开基频的要求及长期在轨运行对太阳电池阵发电功率的需求。
