During airport approach and landing, airstream noise is a dominant aircraft noise source, and the noise that is generated at the side edges of the deployed flaps, elevons, and slats is an important component of that noise. The noise radiating from these side edges is caused by their interaction with the strong vortex systems that are present along these edges. The purpose of flow disruption devices is to reduce that noise.
