Abstract : An axisymmetric, 12.5 cm (5 inch) diameter laboratory ramjet combustor was built and checked out. Experiments were started to determine detailed flow data relevant to gas generator ramjets. Combustion temperature and species concentrations profiles indicate a significant effect of reaction kinetics and mixing on combustion in the beginning of the mixing region downstream of the gas generator nozzle. Comparison of the experimental data with model predictions by Science Application, Inc. was initiated. For the velocity and turbulence intensity measurements, data linkage between the two-color, three-beam laser doppler velocimeter and the computer was established and measurements were started.
