BIE-based aeroacoustic design procedure

Risultato della ricerca: Articlepeer review

Abstract

A propeller low noise design procedure based on boundary integral equation ispresented. The aerodynamic field is computed via a potential-based boundary elementmethod for lifting body while the aeroacoustic emitted field is calculated onthe basis of the Ffowcs Williams-Hawkings equation. Families of airfoils sectionsare aerodynamically processed to select the ones that meet the requested performance.Successively, the airfoil sections characterized by the lowest noise emission,among the previously selected ones, are chosen to built the propeller blade.Eventually the whole propeller aeroacoustic performances are analyzed.
