초록

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 s...

1. A flow disruption device, operatively associated with a surface of a vehicle structure across which an air flow is flowing in a direction substantially extending from a leading edge portion of the surface toward a trailing edge portion of the surface and wherein the vehicle structure also comprises a substantially vertically oriented side edge portion disposed within a substantially vertical plane, for reducing noise generated by the air flow as the air flow flows across the substantially vertically oriented side edge portion, comprising: a body dispo...
