Authors Abstract
Content
The Smart Radiation Device (SRD) is a new type of thermal control material for spacecraft. By changing its emissivity without using electrical instruments or mechanical parts, the SRD decreases the temperature variation of the applied place. The SRD changes its emissivity physically depending on its temperature. The drawback of the SRD is its high solar absorptance. In order to reduce the solar absorptance while keeping its emissivity variation, the wide band filter was designed for the SRD. The function of the wide band filter is to reflect sunlight and to transmit infrared light. The SRD with the wide band filter is called as the Smart Radiation Device with Multi-layer films (SRDM) and the target value of its solar absorptance is 0.13.
