“…These radiators are lightweight and simple, and present great promise, but it is difficult to apply them to higher power applications. On the other hand, deployable radiators [4,5], which expand radiator fins in orbit in order to increase the radiation area, have been studied and applied to several spacecrafts. However they are limited to applications on large satellites only, due to their weight, complicated construction, and need for large heater power in the case of cold.…”
