High Energy Hydride Propellants

Physical Sciences Inc. (PSI) proposes to develop safe IM Compliant, high performance solid rocket propellants for advanced interceptor capabilities with significantly increased delta-v. PSIÆs innovative propellant formulations capitalize on novel ingredient technologies that provide for 10% increase in Isp relative to state-of-the-art aluminized HTPB/AP composite propellants. Analysis of boost stage and upper stage propulsion systems using PSIÆs propellant show that up to 12.5% and 20% performance improvements can be achieved, respectively. The Phase I effort focused on propellant safety, thermal stability, and ballistic performance assessments for several candidate high Isp formulations. The Phase II will focus on formulation down-selection, mixing scale-up, and evaluation of mechanical strength properties, Insensitive Munition characteristics, burn rate pressure sensitivity, and performance in a small-scale 2x4 rocket motor.
