Parameter sensitivity analysis for the solar array of the satellite thermal design

The problem of the satellite thermal design is analyzed by means of the theory of the system sensitivity analysis and the system sensitivity equations of the satellite thermal design are derived. As an example, the system sensitivity equations are applied to the parameter sensitivity analysis of the thermal design of the solar array of a satellite and the sensitivity of each design parameter is discussed. Such an algorithm provides a basis for the determination of the physical and structural parameters in the solar array thermal design of a satellite and provides an analysis method for the reliability validation of the thermal design and the operating reliability of the satellite. The efficiency of the thermal analysis and thermal design is improved if the variation analysis method is used to the thermal analysis and the thermal design of the satellite.
