摘要
提出了一种新的太阳帆板遮挡计算方法,用于组合体航天器的能量平衡分析与计算。根据航天器轴线与帆板转轴垂直的几何关系,将其沿轴线离散化为若干平面的集合,将所分析的帆板离散化为点集,判断离散点沿太阳矢量逆向是否经过离散的舱体平面或其它帆板平面,以此确定遮挡关系。通过仿真计算得到不同入射太阳方向下某组合体对应的遮挡区域,结果表明,新方法适用于轴对称形状组合体航天器的帆板遮挡分析。
A new method for calculating the solar panel shadow in a spacecraft complex was proposed, which can be applied in the energy balance analysis. According to the geometric relation- ship, the body was divided into several sections and the panels were divided into several units. Then whether the projection of one unit on a section plane through solar vector was inside the section was determined. The integral shadow was then obtained. The shadow areas of a spacecraft complex were calculated by simulation. The results showed that the new method was suitable for shadow analysis axisymmetric spacecraft complex.
