A wing/winglet configuration, which basically comprises: (a) a wing having upper and lower wing surfaces, a wing leading edge, a wing trailing edge, and a wing tip; and (b) a winglet having upper and lower winglet surfaces, a winglet leading edge, a winglet trailing edge, and a winglet tip, where th
A wing/winglet configuration, which basically comprises: (a) a wing having upper and lower wing surfaces, a wing leading edge, a wing trailing edge, and a wing tip; and (b) a winglet having upper and lower winglet surfaces, a winglet leading edge, a winglet trailing edge, and a winglet tip, where the winglet is mounted to the wing tip at a winglet/wing tip intersection and extends upwardly from the wing tip Aft portions of the upper wing surface and upper winglet surface are flattened near the winglet/wing tip intersection to substantially reduce flow separation near wing/winglet intersection.

A wing/winglet configuration for an aircraft having a longitudinal axis, a vertical axis, and a transverse axis, comprising: a. a wing having upper and lower wing surfaces, a wing leading edge, a wing trailing edge, and a wing tip, where a wing chord may be defined for any given portion of the wing
A wing/winglet configuration for an aircraft having a longitudinal axis, a vertical axis, and a transverse axis, comprising: a. a wing having upper and lower wing surfaces, a wing leading edge, a wing trailing edge, and a wing tip, where a wing chord may be defined for any given portion of the wing which extends between the wing leading and trailing edges; and b. a winglet leading and trailing edges; and surfaces, a winglet leading edge, a winglet trailing edge, and a winglet root, where i. a winglet chord is defined for any given portion of the winglet, the winglet chord extending between the winglet leading and trailing edges, and ii. the winglet root is attached to the wing tip at a wing/winglet intersection; wherein c. a corner flow region is defined as the portions of the wing upper surface and winglet upper surface near the wing/winglet intersection at which flow separation is likely to occur; d. first and second reference planes are defined for the wing and winglet, respectively, where i. the first reference plane extends through the wing leading and trailing edges just outside the corner flow region, and ii the second reference plane extends through the winglet leading and trailing edges just outside the corner flow region; e. wing and winglet chord planes may be defined for any given wing chord and any given winglet chord, respectively, where i. the wing chord plane is parallel to the longitudinal axis and perpendicular to the first reference plane, and ii. the winglet chord phase is parallel to the longitudinal axis and perpendicular to the second reference plane; and f. for any given chord plane which intersects the wing upper surface in the corner flow region, a wing reference point is defined as a point on the wing upper surface that is furthest from the first reference plane, where a vertical distance between the wing reference point and an uppermost point on the wing trailing edge furthest from the first reference plane and in the given wing chord plane is less than 4.5% of the length of the wing chord associated with the given wing chord plane.
