Aeroacoustics and Aircraft Noise


  • Joana Rocha Carleton University


Noise generated by aircraft is a common complain nowadays, specially for communities near airports. The reduction of noise from aerodynamic origin is one of today major industrial challenge, specially in the field of aviation, even more considering the gradually more stringent noise standard from ICAO (International Civil Aviation Organization). It is therefore desirable to accurately predict the noise generated by turbulent flows, so the noise reduction can effectively be addressed. Aeroacoustics is the study of noise generated by turbulent fluid motion, and by aerodynamic forces interacting with solid surfaces.  Aeroacoustic involves coupled aerodynamic and acoustics phenomena. Because of the multi-disciplinary nature of Aeroacoustics and the diversity of the potential applications, Aeroacoustics courses are typically complex and taught at the graduate level and/or at the last year of graduation, requiring the student to be familiar with mathematics, physics and computational techniques. This paper will outline a number of important topics to consider when studying aeroacoustics and aircraft noise, from fundamental concepts to the more advanced and complex topics. Applications to engineering and industry problems are also presented.  Both subsonic and supersonic flows are discussed, with emphasis given to turbulent flow induced noise in aircraft.
