摘要： The present invention is a composite solid propellant designed to operate in three distinct combustion regimes under various pressure states in the combustion chamber of a solid rocket motor. The design of this propellant facilitates desirable rocket motor operational characteristics, including throttleability, extinguishment, and self-destruction or detonability. The propellant contains ingredients that modify the propellant combustion characteristics to provide the desired behavior, including a surfactant and unaggregated, unagglomerated dispersed primary nanoparticles of aluminum in a polymer binder.
