This paper reviews several decades' worth of research on the topic of slat noise arising from
high-lift systems of commercial aircraft. A high-lift system is commonly used for providing …

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 …

Experiments were conducted to assess the aeroacoustic characteristics of a 30P30N three-
element high-lift airfoil fitted with two different types of slat cove fillers in the Aeroacoustic …

Experimental measurements were carried out to assess the aerodynamic and aeroacoustic
performance of an MDA 30P30N airfoil fitted with two different types of slat cove fillers. The …

To improve the current understanding of flap noise generation mechanisms in high-lift
devices used by small-to large-size commercial aircraft, a detailed study of both two-and …

The leading-edge slat of a multielement wing is a significant contributor to the acoustic
signature of an aircraft during the approach phase of the flight path. An experimental study of …

Noise reduction capabilities of slat cusp serration were experimentally assessed and
demonstrated for a 30P30N three-element high-lift airfoil fitted with two different types of …

We investigate the slat narrowband peak noise generating mechanism. Unsteady flow data
were generated by a lattice-Boltzmann-based commercial code for four configurations …

Abstract Experimental measurements using Particle Image Velocimetry were carried out to
understand the flow characteristics of a 30P30N high-lift airfoil with and without slat cove …

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 …
