The Handley-Page Automatic Slot

THE SLOTTED wing first came into prominence as a factor for securing increased lift from an airfoil, when F. Handley Page, the originator, described it in the Aeronautical Journal, June 1921. The purpose of the Handley-Page slot, or auxiliary airfoil, is to maintain the continuity of flow over the upper surface of the airfoil at angles considerably above the burble point, or angle of maximum lift, in order to realize a lift value substantially greater than that possible with the ordinary airfoil.
