An Investigation of Solid Propellant Combustion in Standard and High Acceleration Environments.

Abstract

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, two-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. 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 low as 100 psi. A comparison is made between AP/binder sandwich combustion and propellant combustion.
