Patent number: 10737773Abstract: 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 trailing edge profile (305) having a perpendicular projection onto a plane normal to the winglet inner or root chord (342), said projection creating a winglet profile curve approximating a compound curve composed of two arc segment (306, 307).Type: GrantFiled: August 20, 2018Date of Patent: August 11, 2020Assignee: Aerostar Aircraft CorporationInventor: Stephen R.
