Abstract:

How variations in propellant ingredients affect mix-to-mix propellant burn rate and mechanical properties is defined. Source, size, shape, and particle size distribution of ammonium perchlorate are variations studied. Techniques were developed through which any lot of ammonium perchlorate can be characterized in such a way that an exact definition of oxidizer blend is available for meeting precisely the burn rate and physical property requirements in processible CTPB and HTPB propellants. The techniques were confirmed in demonstration five-gallon mixes. Mechanical property and ballistic assessment of the techniques validity was accomplished. Modified author abstract
