A wing incorporating a wing tip with a curved leading edge and a curved trailing edge to minimize induced drag for a given wing form is disclosed. The curve of the leading and trailing edges of the wing tip may be described generally as parabolic, elliptic, or super elliptic. A finite tip segment may be included with a sweep angle between the end of the curved leading edge and the end of the curved trailing edge. The wing tip may also include a spanwise camber.
1. A curved wing tip connected to a wing of an aircraft, the wing having a wing leading edge and a wing trailing edge, the aircraft in a x′-y′-z′ reference system where x′ is a longitudinal axis of the aircraft, y′ is a horizontal axis of the aircraft, and z′ is a vertical axis of the aircraft orthogonal to x′ and y′, the curved wing tip in a x-y-z reference system where x is parallel to x′, y is tangent to a surface of the wing, and z is orthogonal to x and y, the curved wing tip comprising: a leading edge curved to maintain attached air flow and defini...
