A boundary layer control device including a rotating cylinder mounted on a shaft disposed along the trailing edge of the wing of an aircraft and a flap structure secured to the shaft on which the rotating cylinder is mounted. In the preferred embodiment, the flap structure is coupled to the shaft by brackets, each of which having one end pivoted about the shaft and an opposite end to which the flap is pivotally supported. This arrangement facilitates rotation of the flap structure between a first “cruise”position in which the flap structure is disposed s...
Boundary layer control apparatus for use with wing members of a tilt-rotor VTOL aircraft, comprising: a cylindrical body supported for rotation on each wing of the aircraft and extending along a major portion of the lateral extent of each said wing, said cylindrical body being continuously driven in rotation about an axis which extends substantially parallel to said lateral extent of said wing, and flap means coupled to each said wing and including means for moving said flap means relative to said rotatable cylindrical body between a substantially horizo...
