ABSTRACT:
Burning rate promoter (e.g. n-butylferrocene, n-hexylcarborane) is incorpted into resonance rods that are used to eliminate combustion instability of solid propellant. As the solid propellant burning progresses the resonance rods undergo ablation, and as ablation takes place, subsurface quantities of the burning rate promoter are exposed and continuously released into the combustion zone to catalyze the combustion process. This invention also employs porous resonance rods which contain the burning rate promoter and a selected material for suppressing combustion instability as infiltrants.
