A dual-configuration airfoil having a thin profile which is adapted to foster high-speed flight, and having a pivotable portion on the upper surface which is movable upwardly for selectively increasing the thickness of the airfoil. In one embodiment, the pivotable portion pivots about an axis which coincides generally with the leading edge of the airfoil. The thickness of the airfoil when the pivotable portion is fully raised is about twice the thickness of the airfoil when the pivotable portion is fully retracted. A rigid connecting section forms part o...

An airfoil construction, comprising: (a) upper and lower surface structure which connects leading and trailing edges so as to form a relatively thin profile which is adapted to foster high speed flight, with one portion of the upper surface structure being pivotable upward about a hinge line that coincides generally with the leading edge of the airfoil, for increasing the thickness of the airfoil, and the chordwise length of said pivotable portion being substantially less than the chord length; (b) a connecting section which forms part of the airfoil upp...
