Description:
Review of a systematic search for practical solutions in the areas of space shuttle cryogenics, flight operations, ground operations, and safety. The insulation of the main-propulsion hydrogen tanks for both booster and orbiter to prevent water condensation is considered, as well as the insulation of the orbiter's orbital cryogen tanks for ground storage. Two approaches to the feeding of cryogens are outlined - namely, an approach depending on a periodic axial force to settle propellants and refill the basket, and a method of continuous feed through a capillary network adjacent to the walls throughout the tank, the latter method being independent of vehicle thrust. The development of reliable cryogen components is discussed, and the results of studies of launch-abort problems, shuttle approach and landing techniques, and the tolerance of ?deconditioned' crew and passengers to shuttle reentry g-loads are cited.
