An improved winglet design is presented for aircraft wherein the winglet configuration is well suited for aircraft wings having moderate to no aft swept, or wings having forward swept. The winglets (302) are located at the outer end of each wing (300) and curve upwardly as they extend outwardly from their intersection (304) with the wings (300). The curvature profile (303) of the winglets (302) when viewed from the rear (or front) of the aircraft at least approximates a specified curve profile made up of more than one curved section, e.g. the winglet tra...


1. An aircraft including a central fuselage and a pair of wings statically secured to the sides of the fuselage, each wing comprising: an inner end secured to the fuselage, an outer end, a leading edge, and a trailing edge; anda winglet having an inner end, or transition, section, an upper, or soil, section; a leading edge and a trailing edge;wherein the inner end of said winglet is connected to the outer end of said wing, and the leading and trailing edges of the winglet are continuations of the leading and trailing edges of the wing, respectively;where...
