| 摘 要： | 文章研究了红外加热笼边缘效应对卫星表面到达热流密度均匀性的影响,主要通过增加边缘加热笼并将其翻转一定角度的方法,对红外加热笼的设计进行优化,以改进卫星表面的到达热流密度均匀性。建立了变角度情况下蒙特卡罗仿真计算的几何模型,对3种情况进行了计算和分析,得到了对红外加热笼的边缘效应进行优化设计的方法,可以用于指导多种情况下的红外加热笼设计。

| Abstract: | The margin effect of infrared heating array on the flux uniformity on spacecraft surface is discussed in this paper. By adding a margin heating array with a certain angle, the infrared heating array can be optimized and the flux uniformity on pacecraft surface can be improved. Three modes are calculated and analyzed based on the geometry models of Monte Carlo simulation with different angles, and a method is found to optimize the margin effect of infrared heating array, which would be useful for the design of infrared heating arrays in many ways. |
