Insulation For Cryogenic-Liquid Tanks

Rigid foam and radiation shields prevent excessive heating in variety of environments. Report discusses design, development, and test of thermal-protection system for liquid-oxygen and liquid-hydrogen tanks of now discontinued Shuttle/Centaur G' project. System protects tank from excessive heat before and during launches, while in orbit around Earth, and during premature landings from aborted launches. Designed to withstand stresses of launch and emergency landing, acoustical loads, rapid changes in pressure, and impingement of rapidly flowing gas near vents of cargo bay in Space Shuttle. Primary requirements in design, system presents no hazard to Space Shuttle or its crew.
