Aircraft noise prediction via aeroacoustic hybrid methods - development and application of onera tools over the last decade : some examples.

Abstract

This article focuses on advanced noise prediction methodologies, in regard to aircraft noise mitigation. More precisely, the so-called aeroacoustic hybrid methodology is first recalled here, before illustrating its potentialities through several examples of application to realistic aircraft noise problems. Among other things, this paper highlights how Onera has contributed to the development of reliable computational methodologies over the last decade, which can now help in solving aircraft noise issues.
