Abstract:
Nonmetallized double base propellant and ammonium perchloratebinder sandwich combustion were studied in standard and high acceleration environments. Experimental techniques used were high speed motion pictures, two-color schlieren and pressure-time trace determination of burning rates. The double base propellant was studied at pressures to 1250 psia and accelerations to plus or minus 1000 gs. Two binder systems were used in the APbinder sandwiches. Tests were conducted with two binder thicknesses at 400 psia and with acceleration levels of zero and 100 gs. It was found for double base propellant that the temperature increased continuously from the surface to the visible flame and that acceleration induced burning rate augmentation occurred. Acceleration apparently modified the surface or subsurface combustion zones. APbinder sandwich combustion was found to be acceleration sensitive with binder flow being the most plausible mechanism.
