  • Aircraft with elliptical winglets
    Patent number: 6484968
    Abstract: An aircraft with swept back wings has winglets (202) at the outer ends of its wings (200). The winglets (202) curve upwardly as they extend outwardly from their intersection (204) with the wings (200). The curvature of the winglets (202) at least approximates a conical section curvature, e.g. an elliptical based on an ellipse having a major axis that extends vertically and coincides with the intersection (204) of the outer end of the wing (200) and the inner end of the winglet (202).
