American National Standard Methods for Measurement of Supersonic Jet Noise from Uninstalled Military Aircraft Engines

157,00 €

Details

This standard describes procedures to measure jet noise from uninstalled military aircraft engines with
supersonic exhaust flows. The methods pertain to propulsion systems mounted on outdoor test stands
with appropriate inlets and representative nozzles. Detailed measurement procedures are described for
near-field acoustical characterization. These data can be used to establish baseline noise levels, assess
effectiveness of noise reduction technologies, estimate personnel noise exposure, and provide full-scale
data for refinement of engine noise models. Far-field measurement procedures are described to provide
data for estimates of community noise. This standard describes required measurement instrumentation,
signal processing, data formatting, and measurement uncertainty. This standard does not apply to
commercial engines, dual-use engines, or other engines covered by FAA/ICAO noise certification
requirements.
