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 12 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 Nsq cm.
