Conceptual Analysis of Electrochromic Radiators for Space Suits 2009-01-2570
Electrochromic devices offer potential benefit as variable emissivity radiators for advanced extravehicular activity (EVA) suits. Supplementing (or even replacing) the water sublimator with radiators will result in reduced mass consumption for heat rejection, and radiators can be effective in environments where sublimation is not possible. The exotic properties of electrochromic devices (ECDs) may also lead to radiators that are capable of adapting, without mechanical actuation, to changing EVA operations and environments. Three concepts for the implementation of flexible electrochromic radiators are presented, along with a preliminary thermal analysis for each configuration.
