Description: Nonmetallized double-base and composite propellant, metallized composite propellant, and ammonium perchlorate (AP)/binder sandwich combustion were studied in standard and high acceleration environments.  Experimental techniques used were high speed motion pictures, tow-color schlieren, laser schlieren, and centrifuge mounted combustion bombs.  It was found for double-base propellant that the temperature increased continuously from the surface into the visible flame.  Acceleration induced burning rate augmentation occurred and resulted in elimination of the visible flame.  Acceleration apparently modified the surface or subsurface zones.  AP/binder sandwich combustion was also found to be acceleration sensitive with binder flow-AP interactions proposed as the mechanism.  Composite propellants burned with local diffusion flames to pressures as slow as 100 psi.  A comparison is made between AP/binder sandwich combustion and propellant combustion. (Author)
