Paper Abstract

This paper describes the thermal design and analysis of the HOSS (Hydrogen On-Orbit Storage and Supply) liquid hydrogen dewar. This task is being carried out by the Space Dynamics Laboratory at Utah State University under contract from NASA Lewis Research Center. The vacuum jacketed 80-liter dewar is designed for a mission life greater than 30 days. The design uses concentric G-10 fiberglass support tubes and multilayer insulation to thermally isolate the hydrogen tank. Heat load trade off studies were performed based on the support tube thickness, plumbing size, and vacuum shell temperature. The dewar employs a liquid nitrogen cooled shield to provide a non-venting ground hold capability of more than 96 hours for launch preparation. Analysis has shown that a greater than 30 day mission is feasible even with a mechanically robust design capable of withstanding most launch environments.
