DEVELOPMENT OF HIGH-ENERGY METALIZED PROPELLANTS.
Abstract
Results of propellant research and development and engineering investigations of a gelled N2H4 fuel containing Be (Beryllizine) are reported for the 3rd quarter of a 12-month program. Significant improvement in the compatibility of Be with N2H4 was achieved by treatment of the metal powder with water, and the average gas evolution rate of mixtures of treated Be with N2H4 now meets the program goal. Carbopol-940 was shown to be responsible for significant increases in the gas evolution rate of these mixtures, but modified polyacrylate gelling agents were free of this effect. Results of tests of Beryllizine-21G in a 1/4-in. -dia flow-loop are compared with data obtained on this fuel in the capillary viscometer. Flow characteristics are comparable in the two types of apparatus. The data indicate a need for greater control of fuel characteristics and temperature than was obtained in the tests discussed. The studies of the ignition of Beryllizine-21G with N2O4 were completed, and the Modified Centrojet injector utilizing the 90 deg mixing and deflector, was selected for combustion tests. The effectiveness of the hot-core principle of injector design was demonstrated in the ignition of Be powder. (Author)
