An experimental investigation was conducted to study the effects of inlet step height on ignition and flammability limits and recirculation zone and boundary layer combustion phenomena of various hydrocarbon fuels. A windowed two-dimensional solid fuel ramjet SFRJ was utilized. Hydrocarbon fuels were burned under conditions similar to the actual flight were studied using a variable geometry inlet, an automatic data acquisition system, and high speed motion pictures of the interior of the combustion chamber at the recirculation zone and the boundary layer development region. Data was obtained at a mass flux of 0.2 1bmin2-sec at a nominal air inlet temperature of 1000 R with pressures ranging from 100 to 150 psia.
