Abstract

The uncertainty of the space radiation environment model has an impact on the evaluation of the solar absorption rate of spacecraft thermal control materials in the space radiation environment. This paper uses the space integrated radiation ground simulation test device to experimentally study the solar absorption rate change law of the ITO/Kapton/Al thermal control film under the electron and proton irradiation environment, and then the uncertainty of the space radiation environment model is compared to the ITO/Kapton /Al thermal control film to analyze the influence of solar absorptivity. The research shows that with the increase of the radiation fluence, the influence of different uncertainties on the solar absorption of the thermal control film first increases and then decreases, and the final effect is basically negligible; the uncertainty on the solar absorption of the thermal control film material When the uncertainty factor increases, when the uncertainty factor is less than 1, the relative deviation caused by the uncertainty of the space radiation environment model to the solar absorption rate evaluation of the thermal control film is positive, when the uncertainty factor When it is greater than 1, it is negative.
