| 摘 要： | 考虑空间轨道外热流、卫星表面自身辐射、热载荷等因素影响,建立卫星温度场计算模型,在采用蒙特卡罗(Monte-Carlo)法求解卫星复杂辐射边界条件的基础上,利用有限容积法对卫星在轨飞行阶段的瞬态温度场进行数值模拟,计算得到卫星瞬态温度场,并考虑其表面自身辐射及空间轨道外热流等因素,建立卫星红外辐射通量计算模型,计算得到不同时刻、不同热载荷情况下的卫星红外辐射通量分布,并简要分析了在轨卫星热控涂层衰减所带来的表面太阳吸收比的变化对卫星温度场的影响。

| Abstract: | By considering the influences of heat flux in space orbit,self-irradiation of satellite's surface and heat load,the universal thermal model of satellite is developed for analyzing its temperature distribution and infrared feature.The complicated radiative boundary conditions are incorporated and handled with the Monte-Carlo method,and the model is computed with the finite volume method.By taking into account of the external heat flux in the space orbit and the self-radiation of satellite's surface,the infra... |
