【摘要】 太阳帆航天器通过反射太阳光子实现推进,是一类特殊的小推力航天器,因此其逃逸轨道不同于常规化学推进的航天器。文章考虑太阳帆帆面褶皱和鼓起等因素,建立更为真实的太阳帆光压力模型;同时,由日地关系建立三种不同的二维地影模型,并进行了初步的对比仿真研究。研究结果表明:尽管非理想太阳帆和地球遮挡这两个因素短时间的影响很小,但随着时间的推移,会对整体逃逸轨道和逃逸时间产生累积影响。文章的研究结果对于利用太阳帆实现逃逸轨道设计和姿态控制具有一定的指导意义。更多还原

【Abstract】 Solar sailing is a kind of special low thrust spacecraft using solar radiation pressure force as propulsion and the Earth escape trajectories of it are different from those of traditional chemical propulsion spacecraft.In order to form a more realistic solar sail mechanics model,the wrinkle and billowing of solar sail are considered.And then,three different planar shadow models are built according to the relationship between the Sun and the Earth.Preliminary comparisons among these models show that the effect of nonideal solar sail and earth shadow on departure orbit and time is small when time interval is short,but it certainly increases with time.The results can give preliminary guidance to the escape trajectory design and attitude control of solar sailing.更多还原
