Noise generated by civil transport aircraft during take-off and approach-to-land phases of
operation is an environmental problem. The aircraft noise problem is firstly reviewed in this …

The present article proposes an advanced methodology for numerically simulating complex
noise problems. More precisely, we consider the so-called multi-stage acoustic hybrid …

THE noise environment around airports is a major cause of concern worldwide, with many
local communities exposed to high levels of aircraft noise; the effective reduction of such a …

The present article concerns a commonly used methodology for the numerical simulation of
acoustic emission and propagation phenomena. We consider the so‐called multi‐stage …

With the objective of aircraft noise mitigation, we here address the numerical
characterization of the aeroacoustics by a simplified nose landing gear (NLG), through the …

For many years, aircraft noise reduction has been the subject of research studies and
continuous improvements were achieved through an enhanced understanding of the noise …

Characteristics of the generation and propagation of aerodynamic noise are unique to
conventional ground vehicles or aircraft due to the wing-in-ground (WIG) phenomenon. This …

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 …

The present article aims at highlighting the strengths and weaknesses of the so-called
spectral-like optimized (explicit central) finite-difference schemes, when the latter are used …

Taking place within more extensive work that focuses on hybrid methods in aeroacoustics,
the present study is devoted to the data transfer operations that are to be performed between …
