Abstract : Information resulting from this study will allow formulation of new and very general analytical models and criteria to permit a priori design of reliable and stable liquid rocket motors and supersonic air-breathing engines required for future weapons delivery systems. Specifically, the objective of this program is the acquisition of experimental data on the mechanisms of propellant spray combustion energy addition to steady flow fields and propagating pressure disturbances. The data will be used to evaluate expressions describing the dynamics that contribute to the coupling processes between the spray and gas flow fields. These expressions form the basis of steady-state and transient propellant combustion models that bear directly on the problem of predicting performance and the onset of high frequency combustion instability in liquid propellant rocket engines.
