Research Abstract

The purpose of this research is to find out new materials for smart radiator device (SRD). As a result of this research, some materials with higher emissivity or lower emissivity were found, but there was no material with better thermo-optical properties compared to SRD which is mounted to HAYABUSA. As we could get a lot of data and confirm the way of researching materials, we will keep trying to find out new materials for smart radiator device.
