An investigation of solid propellant combustion in standard and high acceleration environments
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)

An optically equipped combustion bomb mounted on a centrifuge and a standard combustion bomb were used in the by: diameter filled with solid propellant by direct casting. The top surface of the propellant was machined flat and left 1/16 inch higher than the generator surface. A cover, bolted into place, compressed the propellant and proved effective in preventing combustion at the grain-wall interface.

The mid-high frequency volume acceleration source is composed by a driver, a tube and a nozzle, where it is installed a volume acceleration sensor. This source produces a voltage signal proportional to the volume acceleration [m 3 /s 2 ] variation, with a nominal frequency range of up to 8, Hz.

The goal of the system is to minimize propellant and the easiest way to decrease propellant usage is to make the system weigh as little as possible.
