摘　　要：文章以某卫星热控涂层的污染研究为目的,针对20N轨控推力器,在推力器羽流流场模拟的基础上,结合污染沉积过程模拟,计算获得了卫星在轨运行期间热控涂层表面的污染沉积膜的厚度,分析了热控涂层太阳吸收率的退化情况。This paper analyzes the plume contamination of the 20 N orbit control thruster of a satellite on its thermal control coatings. Based on the simulation of the thruster plume field and the deposition process,the thickness of molecular deposition on S781 and OSR coatings is calculated in different orbital operation periods and the solar absorptance degradation is evaluated for the thermal control coatings.
