Abstract : Results from the analysis of the acoustic waveforms produced by a cold Mach 3.0 jet were compiled and submitted for publication. Efforts now turn to completing laboratory experiments on the heated, conic-section nozzle, supersonic jet in the U. Miss, facility. Initial shadowgraph images provide insight into the generation of shock-like events in the jet's near-field.
