Synergistic Effects and Deflagration Analysis in Composite Solid Propellant Combustion

Abstract

Using four common catalysts the existence and magnitude of synergistic effects upon burn rate are studied with HTPB-AP composite solid propellants. The effect under study is one whereby at a fixed total catalyst loading the mixture of two catalysts would be more effective in burn rate augmentation than a single catalyst. At 2000 psia all possible combinations of catalysts showed synergistic effects but the effects are weak and within the reproducibility range of the experiments. Ferric oxide and iron blue showed synergistic effects only at 300 and 2000 psia over the pressure range 300-2000 psia. Analysis of the effect of binder-oxidizer reactions upon the surface shape of a two-dimensional sandwich has shown that (a) the faster are these reactions the more deeply will the sandwich obtain a V-shape and b) these reactions are generally fast enough to indeed affect the surface shape.
