Abstract:

The 70 F shelflife of aluminum hydride propellants can be improved by adding small quantities of noble metal catalysts for condensing internally generated hydrogen gas. This program is designed to provide the factual demonstration that the resulting degree of stabilization is sufficient to assure a minimum five years shelflife under silo conditions. To effect such demonstration, samples of a ballistically optimized AlH3NF2 propellant have been placed into storage at 20, 30, 40 and 50 C to determine time-to-failure as a function of propellant composition and storage temperature to verify the models. Propellant off-gas composition and changes in the propellants mechanical behavior are being monitored to derive the capability for shelflife predictions. Author
