| Abstract: | The heat flux measurement method and simulation was illustrated in this paper used in thermal balance test(TBT)of CHANG'E lunar satellite,in which five kinds of radiometers were used.The calibration of the radiometers was undertaken respectively in the separate states and simulated environmental conditions.The response characteristics were given under different heat flux condition.As the characteristic of temperature distribution must be validated,the transient heat flux state was designed during TBT.The thermal insulation radiometers were used as a controling radiometer mainly action in TBT. |
