Design of Thermal Radiative Properties of Multilayer Films on a Variable Emittance Radiator

New thermal control material named Smart Radiation Device (SRD) has been studied to apply for spacecraft. Infrared radiative properties of the SRD change depending on its own temperature without electrical or mechanical instruments. The SRD however shows too high solar absorptance to apply it as a radiator. To overcome such drawback, it is necessary to design and apply the mutilayer films on the SRD for reflecting solar radiation, keeping infrared radiative properties of the SRD. To perform optimum design of the multilayer films, the genetic algorithm (GA) was employed. In this paper, we propose a design of the thermal radiative properties of the SRD with the multilayer films.
