Abstract
An efficient acoustic holography technique for characterizing the noise source of tactical aircraft jet plumes was developed through the bench testing stage in Phase I. A full-scale array of 100 microphone locations was designed to be able to capture the noise of an F-18 in a simulated carrier launch, including effects of deck scrubbing and interactions with the jet blast deflector, in a few seconds of data acquisition. In Phase II, the technique and the array will be tested in model scale using the Small Hot Jet Acoustic Rig and the NASA-Glenn Research Center and in full scale at the Naval Air Station Patuxent River.
