大面积太阳翼国外发展研究

Study of large-area solar array abroad

阐述了大面积太阳电池翼的国外研究现状,并对技术指标进行了分析,研究表明柔性大面积太阳翼是必然的发展趋势。大型伸展机构是大面积太阳翼的重要组成部件,本文论述了国外大型空间伸展机构的研究现状,并对典型伸展机构的结构组成、工作原理和应用方向进行了介绍,研究表明桁架式伸展机构目前被广泛应用。最后,建议我国的空间站采用盘绕式伸展机构支撑的柔性大面积太阳翼结构。

The research status of large-area solar array is expounded and technical indicators are analyzed. Studies have shown that the flexible large-area solar array is the inevitable trend of development. Large stretching institution is an important component of large-area solar array. The research status of large space stretching institutions is described, of which the structure, working principle and the application are introduced. Studies have shown that large space deployable truss is widely used. Finally, the roll-up deployable system supporting flexible large-area solar array is suggested for thespace station in China.
