Abstract
MEMS emissivity control device can be expected as a thermal control device for next generation spacecraft. However, there are uncertain matters such as vibration and impact resistance in launch, heat resistance in space environment, and thermo-optical characteristics, due to the micro-scale structures. For clarifying these matters, emissivity control device was fabricated using MEMS shutter array. In this paper, we report the results about effective emissivity of the device by thermal analysis and by calorimetric method.
