Low Thermal Flux Glass-Fiber Tubing for Cryogenic Service

Abstract

Thin metallic liners that provide leak-free service in cryogenic propulsion systems are overwrapped with a glass-fiber composite that provides strength and protection from handling damage. The resultant tube is lightweight, strong, and has a very low thermal flux. The resultant reduced boiloff of stored cryogenic propellants yields a substantial weight savings on long-term missions (7 days or greater). Twelve styles of tubing ranging from 1/2 to 5 in. (1.27 to 12.7 cm) in diameter were fabricated and tested at operating temperatures from +70 to -423 deg F (294 to 20 deg K) and operating pressures up to 3000 psi (2068 N/sq cm).
