  • High performance aerodynamic airfoil for aircraft wing
    Patent number: 4240598
    Abstract: The invention relates to a high performance aerodynamic airfoil for aircraft wing, wherein the airfoil is biconvex and is such that the corresponding wing comprises an advanced maximum total thickness and at least substantially zero curvature over the major part of the airfoil surfaces of the upper surface and lower surface, downstream of the maximum total thickness, the point of maximum thickness of the lower surface being nearer the leading edge than the point of maximum thickness of the upper surface. The invention finds particular application to the manufacture of fixed or rotary wings of aircraft.
