SYNERGISTIC AND NOVEL EFFECTS IN COMPOSITE SOLID PROPELLANT COMBUSTION

摘要

This report summarizes experiments and analysis concerned with sandwich and cast composite solid propellant combustion. The ingredients used in the experiments are ammonium perchlorate as the oxidizer, hydroxyl terminated polybutadiene as the binder and four catalysts: Harshaw catalyst CU-0202, Fe2O3, ferrocene and iron blue. Cinephotomacrography and the fuze wire technique are used for combustion visualization and burn rate determination. Scanning electron microscopy is used for quenched sample visualization. Areas investigated are (a) analytical and experimental determination of synergistic catalytic effects in sandwich and propellant combustion, (b) the loading of ferrocene into the binder at the molecular level and its effect on sandwich combustion, (c) differential scanning calorimetry of catalyst laden binder and (d) analysis of sandwich deflagration.
