Experimental Study on Solid Propellants

This paper involves the study of optimization of burn rate techniques. Addition of small amount of inorganic and organic substances alters the burn rate. The purpose of this paper is to study the effects of additives on burn rate. Also optimization is done using changing the composition of the reacting species in the propellants. We used AP-PVC and black powder based propellants for the optimization. Additives, Al powder and Iron oxide were used in same propellants strand formulation. These materials are generally used in 1-5% of amount of basic propellants by weight. Optimization of propellant was studied by observing their burning characteristics of the propellant. The result shows that burn rate increase for some additive and decrease with some additive based on the composition of the additives and basic propellant.
