Aerodynamic Noise.

Abstract

The aim is to provide an up-to-date account and authoritative appraisal of aerodynamic noise concepts, theory and experiments. Particular emphasis is given to practical methods for the prediction, measurement and reduction external noise from jet/fan aircraft. Following a brief overview of relevant aircraft design and operational considerations, the main lectures include detailed presentations on the fundamental theory of aerodynamic noise generation and propagation, basic aero-acoustics of jet efflux noise, engine exhaust noise characteristics, fan noise, airframe self-noise, airframe/engine interaction effects, aero-acoustic measurement and analysis techniques, aircraft flyover noise measurement, noise-source identification and location methods, and ground-based facilities with forward-speed representation. A bibliography of 171 items is included in the publication. (Author)
