In certain flight regimes, the leading-edge slat significantly contributes to aeroacoustic noise emissions. This can be attributed to a vortex forming in the slat cove, which is largely caused by flow from the pressure side to the suction side of the wing. Preliminary studies have shown a significant reduction in aeroacoustic emissions when the slat gap is blocked, with minor impacts on aerodynamics except at extreme angles of attack. Current work focuses on developing a continuous-scanning acoustic beamforming array for source localization, as well as design and optimization of a model-scale slat-gap filler.
