In the last decades noise produced by aircraft has become one of the major concerning issues for civil aviation. Everyday, residents living around busy airports experience high noise levels during landing and take-off phases, making the authorities act in terms of noise standard regulations. Current interest in next-generation supersonic aircraft represents a hard challenge for aeroacoustics research community, requiring fast and accurate methods for noise prediction and new technologies for noise suppression. Most common computational aeroacoustics methods rely on noise source reconstruction based on unsteady CFD analysis such as Large Eddy Simulation (LES), due to the necessity to properly capture turbulent fluctuations evolution in near-field domain.
