R&D processes for increasing density of cryogenic propellants at FSEC (Florida Solar Energy Center).

Auteurs : BAIK J. H., T-RAISSI A.

Résumé

Technologies that provide for the densification of cryogenic propellants, conditioning, transfer, storage and mass gauging are of prime interest to the spaceport of the future and space launch activities. Density increases of 8% for LH2 and 10% for LO2 have been shown to have the advantages of reduced gross lift-off weight of a launch vehicle by up to 20% or increased payload capability. In this paper, thermodynamic system analysis will be performed for various liquefaction, densification and recirculation systems. The objectives are to determine the optimum combination of system components including liquefier, cryocooler and heat exchangers for ground support system and launch vehicles.
