Title

Operational Testing Of Densified Hydrogen Using G-M Refrigeration

Abstract

Propellant densification has many beneficial properties when space launch systems are considered. Among these are reduced tank volumes, decreased vapor pressures, and increased enthalpy gain before boil off. Previous NASA investigations have focused on advanced methods of producing densified propellants, but not much work has been accomplished in the area of storing and handling densified propellants. NASA KSC has 50+ years experience in handling cryogenic propellants, but all that experience is with saturated liquids. This work is focused on using existing cryogenic refrigeration technology to subcool hydrogen, and to develop a testbed where propellant handling techniques are researched. Among these topics include continuous operation, zero boil off storage, densification, pressurization techniques, handling of stratification layers, liquefaction, and recovery of boil off losses from chill down procedures.
