Abstract : This report provides a summary of results obtained over the past year in fundamental studies of the chemistry of solid rocket combustion and of combustion instability in liquid rocket combustion. A coordinated research program has been initiated to study separate aspects of the complex multidimensional, multiphase and multicomponent reacting flow characteristic of rocket combustion. The focus of the combustion chemistry studies is on flame reactions of gas phase species formed as decomposition products near the surface of the propellant. These flames typically involve a variety of fuel species and nitrogen oxides as oxidizers. The focus of the combustion instability studies is the effect of atomization and vaporization processes on the oscillatory conditions characteristic of combustion instability. The research objectives, progress and research in progress in each of these areas are summarized in the report. Rocket Combustion, Combustion Chemistry, Combustion Instability, Droplet Vaporization.
