| 摘 要： | 首先根据载人航天器轨道运行段的基本特征，利用球面三角公式推导了：①阳光方向与载人航天器太阳能帆板法向的最佳夹角公式；②圆轨道的受晒因子公式。然后根据理论分析，引入帆板的效率系数。最后借助于计算机代数ｍａｔｈｅｍａｔｉｃａ系统，建立了一种分析帆板最佳受晒的直观、清晰、简便的方法。所得的结论为确定载人航天器的发射窗口提供了依据。

| Abstract: | In this paper,firstly,based on the basic features of spacecraft orbit,the formulae are deducted which are those of the optimum angle between the solar direction and the normal direction of solar array of spacecraft and the sunshine factor of circular orbit;Then,according to theoretical analysis,the coefficients of efficiency of the solar array are derived;Finally,having the aid of computer algebra system MATHEMATICA,a direct,clear and simple method is set,which can be used for analyzing the optimum sunshine of the solar array.The results may be of reference value to selection of launching window of a spacecraft. |
