红外加热笼模拟航天器瞬变外热流的方法研究

The Research of Simulation Method of Dynamic Flux of Spacecraft by Infrared Heating Cage

以某型号航天器热平衡试验为工程应用背景 ,采用理论分析、仿真研究和实验研究相结合的方法 ,建立了红外加热笼和热流计的动态数学模型 ;在此基础上 ,讨论了利用红外加热笼作为热流模拟元件 ,绝热型热流计作为测量元件 ,模拟航天器在轨飞行时表面到达热流密度瞬态变化的方法和技术。

The dynamic mathematical model of infrared heating cage and flux sensor is founded by theory analysis,simulation research and experiment research in the engineering apply background of thermal balance test of some spacecraft.On the base of the model,the technique of simulation of dynamic flux of spacecraft in orbit is discussed,using infrared heating cage as flux simulation unit and adiabatic flux sensor as measure unit.
