An experimental investigation of nonmetallized composite propellant combustion in standard and high acceleration environments was made. Pressed ammonium perchlorate (AP) pellets of varying purity, AP/binder sandwich burners, and propellant strands were employed. AP/binder sandwich burners where studied in an optically equipped centrifuge and color schlieren were taken in a conventional combustion bomb. Ascast and dewetted propellants were used to study the effect of preferential interfacial reactions on burning rate acceleration sensitivity. Results are discussed for the effects of acceleration, pressure, AP purity, and propellant composition on the burning rate. (Author)
