Abstract : This report summarizes work performed on a program designed to study the physiochemical, ignition, and combustion characteristics of a new family of high energy, beryllium-containing monopropellants possessing theoretical specific impulses of greater than 300 lbf-sec/lbm at 1,000 psia exhausted to 14.7 psia. These investigations resulted in development of a safe and practical monopropellant candidate, designated MONEX DW 25G.4-M1, possessing a theoretical specific impulse of 302.4 lbf-sec/lbm and a measured density of 0.0480 lbs/in(3). Sustained combustion of MONEX DW formulations has been demonstrated in end-burning type motors using both pyrotechnic and hypergolic slug ignition techniques. Test firings at the nominal 100 lb thrust level indicate that although good conversion of beryllium oxide is obtained at chamber pressures of greater than 1,000 psia, poor expulsion of solid combustion products is obtained with motors of this type.
