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