Abstract

Tests performed recently at the NASA MSC Spacecraft Materials Laboratory and data reported by Cowley et al. [1] have shown that the application of a thin layer of insulating material to a body will decrease the body cooldown time. As a result of these data, it was postulated that the bonding of an insulating film to the internal surfaces of space chamber cryopanels would likewise decrease their cooldown times. This idea is attractive from the standpoint of decreasing waste time in space chambers, where cooldown of the cryogenic system involves many hours. Teflon thin film, treated by sandblasting to provide nucleate boiling sites, was used in the reported tests as the insulating material because Teflon can be bonded to a metal surface easily. Other insulators tested included various oils and Mylar.
