Abstract The Delayed Detached Eddy Simulation (DDES) and Ffowcs Williams–Hawkings
(FW–H) analogy have been performed to describe the unsteady flow and noise-generation …

Both aerodynamic and aeroacoustic measurements in wind tunnels are necessary for the
study of high-lift devices. The existing wind tunnels have difficulties in simultaneously …

Slat noise during aircraft landing is already a barrier to the development of quieter
commercial airplanes. Investigations have been made by several research groups to …

The slat represents an important airframe noise source as it extends over almost the entire
aircraft wingspan. Most studies of slat noise consider idealized geometries. However, for …

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 constitutes today a major contribution to the total noise emitted by regional jets,
and the mechanisms responsible for their generation are not completely understood. In this …

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 …

The work to be presented aims at studying the effect of a seal on the slat cove surface,
commonly observed in real scale airplanes, on the turbulent structures inside the cove …

A redução do ruído externo gerado por aeronaves operando nas proximidades de grandes
centros urbanos é apontada como uma questão vital para a manutenção e expansão …

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 …
