Abstract:
An investigation was made of materials for vacuum insulation up to 4000 F. ADL-17, graphite fibers, thoria powder, and Ta radiation shields were chosen as insulation components for longterm high-temperature tests on the basis of theoretical studies of both the mechanisms of heat transfer through evacuated insulation materials and preliminary experimental work. Thermal protection systems consisting of these materials were chemically and physically stable enough to be effective insulators for over 100 hr at 3000 and for several hours at 3500 F. Although only readily available materials were used, their insulating performance points to the potential effectiveness of improved materials.
