Abstract
A system and method provides for the manipulation of the aerodynamic characteristics of airfoils and other aerostructures using blowing and/or suction. This system and method uses one or more internal cavities located within an airfoil. An internal cavity is coupled to the exterior surface of the airfoil via one or more slots. A rotary actuator is incorporated into a slot. When the rotary actuator is rotated into a first position, it forms a channel that allows fluid to pass between the internal cavity and the air surrounding the airfoil. When the rotary actuator rotates into a second position, it prevents fluid from passing through the channel between the internal cavity and the air surrounding the airfoil.
