HIGH ENERGY PROPELLANT INGREDIENT RESEARCH AND DEVELOPMENT
Abstract
Studies of the preparation and properties of AlH3-1451 have continued. Magnesium has been incorporated into product made by the continuous crystallization technique; improved thermal stability is observed in product from the larger unit. Flame photometry is used to determine the equivalence point of the AlCl3-LiAlH4 reaction for aluminum hydride synthesis. Feflon FEP showed excellent promise in the laboratory as a material of construction for aluminum hydride crystallization, but adhesion of product still remained a problem in a 9-gallon crystallizer made from FEP stock items. Double base propellant containing magnesium-doped, in situ DPA-treated AlH3-1451 shows a twofold improvement in stability over standard hydride at both 25 and 40 C. Magnesium-doped, in situ DPA-treated, and magnesium-doped, aged AlH3-1451 are remarkably stable at 60 C. Propellant containing aged, magnesium-doped AlH3-1451 decomposed 0.74% after 243 days. Magnesium-doped, in situ DPA-treated AlH3-1451 in double base propellant reached 1% decomposition in 173 days; in composite propellant it reached 0.84% decomposition in 91 days.
