红外地平仪外热流计算

Calculation of Orbital Heat Flux of Infrared Earth Sensors

红外地平仪部分凸出于航天器外表面．除受到太阳辐射、地球反照和红外辐射外，还受到航天器外表面的反射辐射．文中在对包括红外地平仪外表面在内的封闭系统进行辐射分析的基础上，得到红外地平仪外热流的空间有效辐射角系数计算公式；采用蒙特卡洛法，计算了某航天器两个位于不同外表面的红外地平议外凸圆柱体所受的外热流。

The part of infrared earth sensor outside spacecraft surface is not only radiated by solar radiation, earth albedo and its infrared radiation, but also radiated by the reflection of the outside surface of spacecraft of The orbital heat flux of two infrared earth sensors on different panels are calculated with Monte - Carlo method. Imfluence of the radiation reflected by spacecraft surface in the orbital heat flux calculation is also discussed.
