Supersonic Combustion and Burning in Ramjet Combustors,

Abstract

The report discusses research results obtained on the experimental and theoretical studies of subsonic and supersonic burning in ramjet combustors during the period 1 April to 31 March 1972. During this period theoretical calculations showed that nozzle dimensions for a chemically reacting flow must be based on the shifting equilibrium sound speed. Incompatible conditions are obtained when the frozen sound speed is used. The difference in the nozzle area for the two cases is significant. Deviations of the observed wave speed and pressure of detonations in hydrogen-oxygen and hydrogen-nitric oxide mixtures initially at high pressure from the theoretical values were determined to be caused apparently by turbulence in the gas flow behind the wave.
