| Abstract: | The correct determination of effective emissivity, the effective solar absorptivity and the equivalent thermal conductivity of multilayer insulation materials are essential for the thermal control design and the thermal analysis of a spacecraft. This paper discusses their engineering calculation methods of those thermal physical properties. Quantitative values under different conditions are obtained through calculation and analysis, which may provide a reference for the thermal control design of spacecraft. |
