Abstract

This article addresses variations in different parameters of the slat internal geometry for the establishment of their relation with noise generation. Studies were carried out through a numerical method on the commercial version of PowerFLOW 5.3®. Numerical results of the baseline configuration were compared with experiments conducted in a closed section wind tunnel at the Laboratory of Aerodynamics (LAE) of the São Carlos School of Engineering - University
of São Paulo (EESC-USP), Brazil. The agreement between numerical and experimental results of both aerodynamic and aeroacoustic tests validated the numerical methodology. The parameters modified were cusp length, angle of cusp and angle of trailing edge. Cusp length and angle of trailing edge highly influenced the slat noise; the angle of the cusp showed a small relation with noise generation.
