Using densified liquid hydrogen as a cryogenic propellant for launch vehicle applications can reduce fuel tank volumes, decrease vapor pressures, and improve cooling capacity over the normal boiling point propellant. A densified liquid hydrogen test bed has been developed using Gifford-McMahon cryocooler to refrigerate hydrogen inside the 150L storage tank at the Florida Solar Energy Center (FSEC). This work is a collaborative effort amongst researchers at FSEC and NASA Kennedy Space Center. The test bed has an integrated refrigeration and storage system with multiple capabilities including hydrogen liquefaction, densification, and zero-boil-off (ZBO) storage test. This paper focuses on the design considerations, the detailed system descriptions, and the results obtained during initial hydrogen liquefaction and densification tests. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR] |
