中文摘要：

太阳帆的轨道和姿态控制是太阳帆研究的重要领域。在同时考虑太阳帆轨道和姿态的情况下,研究了太阳帆在悬浮轨道的被动稳定飞行问题。通过设计帆的面积和支撑有效载荷杆的长度,使太阳帆在轨被动稳定飞行,主要研究了两个参数对太阳帆稳定性的影响。研究结果表明,太阳帆的面积对帆的稳定性影响较大,面积较小时太阳帆总能被动稳定。杆的长度对帆的稳定性影响不大,给定杆的长度,通过设计太阳帆的面积总能使太阳帆被动稳定。

英文摘要：

The orbit and attitude control is a very important aspect of solar sail research. This paper investigates the passive stability of solar sail with the attitude and orbit considered simultaneously. The solar sail is stabilized passively by designing the area of the sail and length of the boom and how the area and length affects the stability is investigated. The results show that the area is very important for the stability and the length of the boom has negligible influences on the stability. For a given length of the boom, the solar sail can be stabilized by the designing the area of the sail.
