Abstract
A Smart Radiator Device (SRD) was developed by MPBC to meet the growing demand for advanced thermal control in smaller spacecraft. The SRDs exhibit a temperature-dependent emissivity profile due to the metal insulator phase transition of the thermochromic material of the coating. This results in a reduction in heat radiated from the spacecraft in low temperatures and consequently, a decrease in the power demand of heaters. We compared the expected performance of the SRD’s to that of a traditional radiator through three simulated missions, with an emphasis on power and payload temperature swings.
