卫星卷绕式柔性太阳电池阵关键技术研究

The key technical analysis of the roll-out solar array

太阳电池阵是绝大多数卫星在轨运行的唯一能量来源,针对未来6G空间通信建设卫星星座的需求,卫星太阳电池阵需要在输出功率不变的情况下进一步减小质量和体积。卷绕式柔性太阳电池阵具有轻质、高效、无需展开驱动等特性,成为空间太阳电池阵发展的一个重要方向。梳理了卷绕式太阳电池阵发展的历程,介绍了国内外卷绕式太阳电池阵的发展现状,并对关键技术进行梳理,为未来6G卫星太阳电池阵选型及卷绕式太阳电池阵的发展提供参考。

Solar array is the only energy source for the majority of satellites,in view of the great need of the 6G space communication,under the premise that the output power is constant,satellite solar arrays need to further reduce the mass and volume.Roll-out solar array has the characteristics of lightweight,high-efficiency,and no need of the unfold drive,which has become an important direction for the development of space solar arrays.This paper introduces the development process of roll-out solar arrays and the development status of roll-out solar arrays in the domestic and foreign.The key technologies are sorted out to provide a reference for the selection of 6G satellite solar arrays and the development of roll-out solar arrays in the future.
