Abstract : A silicon compound as a burning rate catalyst for a solid propellant composition is disclosed along with the solid propellant composition for which the silicon compound is an effective catalyst. The silicon compound is selected from a class of silicon compounds characterized by having one or more silicon bonds selected from silicon to hydrogen bonds, silicon to nitrogen bonds, and silicon to carbon bonds. Representative silicon compounds of the described class of compounds include p-bis(dimethylsilyl) benzene, tris(dimethylsilyl) amine, triethylsilane, hexamethyldisilane, bis(dimethylamino) dimethylsilane, bis(dimethylamino) methylsilane, octylsilane, hexamethylcyclotrisilazane, and dimethyldiicyanatosilane. The burning rate of the solid propellant composition varies as a function of the silicon content in the propellant composition which is additionally comprised of hydroxyl terminated polybutadiene binder.
