DEVELOPMENT AND TEST OF HIGH ENERGY SOLID PROPELLANTS

Abstract

The objective of this contract is to conduct theoretical and experimental investigations resulting in the demonstration of beryllium hydride propellants delivering in excess of 280 lbf-sec/lbm at standard conditions. Results of 15-lb beryllium motor firings confirm earlier correlations showing high flame temperature and oxidation ratio to be significant factors in obtaining good efficiencies with beryllium propellants. Decreasing nozzle approach angle and reducing AP particle size were also found to improve the efficiency of beryllium propellants. Initial firings of LMH-2 propellants containing 17% LMH-2 gave delivered Isp 15/1000 values of 275.4 for AP-treated LMH-2 and 278.6 for wax-treated LMH-2. Vacuum baking and air desorption were found to be necessary to eliminate porosity of LMH-2 propellants. AP treating and wax treating of LMH-2 continued to be effective for improving the processibility of LMH-2 propellants.
