Abstract
Various embodiments provide systems and methods for noise reduction for lift-augmentation wing-sections (e.g., flaps, slats, elevons, etc.) by the use of flow disruption devices placed upstream of vortex generation locations. The flow disruption devices may reduce the noise radiating from side edges of lift-augmentation control wing sections. An embodiment flow disruption device may include a body configured to protrude into a flow over a vehicle's surface, wherein the body is coupled to the vehicle upstream of a side edge of a structure of the vehicle such that a wake produced by the body introduces unsteadiness and a flow velocity deficit in a vortex formation region of the side edge of the structure.
