Near-field noise measurements of a high-performance military jet aircraft
Published near-field analyses of full-scale jet noise are limited, and the application of observed laboratory-scale phenomena to full-scale jets is not well understood. To obtain a greater understanding of the connection between radiated noise and source characteristics in full-scale, heated, supersonic jets produced by military aircraft, extensive acoustical measurements were made in the geome...

متن کاملLevel-educed Wavepacket Representation of Noise Radiation from a High-Performance Military Aircraft
An analytical wavepacket-based jet noise model has been applied for the first time to highperformance, military aircraft noise. Ground-based acoustical measurements were made of a tethered high-performance military aircraft with one engine cycling through four engine conditions. The resulting spectra have been decomposed into fine and large-scale similarity spectral components. The spatial dist...
متن کاملSpatiotemporal Correlation Analysis of Jet Noise from a High-Performance Military Aircraft
Correlation analyses of ground-based acoustic-pressure measurements of noise from a tethered F-22A provide insights into the sound-field characteristics with position and engine condition. Time-scaled single-point (auto) correlation functions show that, to the side of the nozzle exit, the temporal-correlation envelope decays rapidly, whereas the envelope decays more slowly in the maximum radiat...
متن کاملSimulation of Supersonic Military Aircraft Jet Noise
Background: There is a growing need to reduce significantly the noise generated by high-performance, supersonic military aircraft. The noise generated during takeoff and landing on aircraft carriers has direct impact on shipboard health and safety issues. Also, noise complaints are increasing as communities move closer to military bases or when there are changes due to base closures and realign...
