摘要
空间光学遥感器热控工作旨在保证遥感器所需温度水平和温度梯度 ,以满足遥感器高质量成像要求。根据遥感器的结构特点和热光学指标要求 ,建立了遥感器及其热控系统的热平衡方程 ,对各热交换项进行了剖析 ,并采用Nevada和MSC/Patran等软件对某空间光学遥感器进行了模拟仿真 ,得到其对地工况和对日工况的热平衡结果。
The thermal_controlling of a space optical remote sensor (SORS) is aimed at maintaining work temperature requirements to obtain images with high quality and resolution. A thermal analysis model of the optical remote sensor is built according to its structure characteristics and its thermal optics performance. The thermal performance of SORS is simulated by means of softwares Nevada and MSC/Patran. The analyzed results are also presented.
