This study investigates the slat noise of a two-dimensional scaled, unswept, and untapered
MD30P30N high-lift model. The experimental data refer to aeroacoustic and aerodynamic …

The design of a microphone array affects the performance of beamforming algorithms in the
localization and evaluation of acoustic noise sources. This paper addresses a circular …

This paper reports a study of the sound emitted by a slat of a two-dimensional three-element
MD30P30N airfoil, on which a two-dimensional excrescence was installed to represent a …

Slat noise experiments are sometimes performed to provide data for the validation of
numerical procedures. Under such circumstances, closed-section wind-tunnels, in contrast …

Air traffic has developed rapidly in the last decades. The noise generated from aircraft can
impair the health of passengers and airport residents, so it is necessary to reduce aircraft …

A the lift increasing during take-off and landing maneuvers, the slat and flap high-lift devices,
are present in most commercial airplanes. This devices are responsible for a significant part …

The development on Environmental Regulations related to aircraft noise propagated to the
vicinity of airports forced the industry to investigate the noise sources and look for …

Two-dimensional high-lift airfoil models noise investigations are normally conducted in
closed-section wind-tunnels owing to their convenience in comparison to open-section ones …

This paper shows an overview of design criteria and facility specifications of the low-speed,
closedcircuit wind-tunnel located at the University of Sao Paulo, Sao Carlos School of …

This paper summarizes the efforts and main achievements by the authors on the topic of slat
noise. Wind tunnel experiments and numerical simulations with a Lattice-Boltzmann …
