Abstract
A flow control actuatorfor a body exposed to fluid flow comprises first and second flow surfacesspaced to define an elongate gaptherebetween. An elongate control element is disposed in or adjacent the gap and has an externally facing arcuate surface and defines a first slotbetween the control element and said first flow surface and a second slot between said control element and said second flow surface. The control elementis moveable to allow the width of said slots to be adjusted generally proportionally. The flow of pressurized flow control fluid passes from a plenum chamberout through one or both slotsto be deflected around the arcuate surface under the influence of the Coanda effect. The flow control actuatormay be provided in the trailing or leading edge of an aerofoil; alternatively it may be provided between two surfaces spaced to provide said gap but otherwise providing a generally continuous surface.
