The lift and drag performance of all vehicles is strongly influenced by viscous effects, and in turn, laminar separation bubbles. This application employs an effective fluid boundary layer control strategy that reduces parasitic drag, allows for more usable angles of attack, and delays or stops separation. In the approach of this application, the control surface effectively uses the Magnus effect to delay or stop a separation bubble from forming, which can increase lift, reduce drag, and delay degrees of stall by directly manipulating the velocity gradient in the fluid boundary layer.
