敏捷型卫星的相机外热流变化及其抑制措施效果分析

Analysis on heat flux fluctuation and its inhibition strategies for agile satellite camera

    摘要
  • 摘要: 文章根据空间外热流理论建立了敏捷型遥感卫星的空间相机外热流计算模型，针对相机的外热流变化情况，选择典型计算工况并对其外热流特性进行了仿真分析，得出了工作模式及卫星姿态变化对相机主要部件热流的影响。为解决外热流分布不均和波动剧烈问题，提出了加长相机遮光罩和加装热防护门2种抑制方案，并对方案的效果进行了分析评价。

     

    Abstract: A thermal model of the space camera for an agile satellite is built according to the space heat flux theory. The heat flux onto the space camera is analyzed and the effect of complex attitude maneuver is discussed. The method of restraining heat flux fluctuation by lengthening the camera lens hood or fixing a thermal control door are analyzed with evaluation.
