Parametric Study of Novel Passive Thermal Control Technology for Spacecraft
Thermochromic variable emissivity materials (VEMs) are a relatively new passive thermal control technology used for spacecraft radiators. VEMs passively change their emissivity based on their temperature, with VEMs having low emissivity at low temperatures and high emissivity at high temperatures. …
