Abstract

Methods and systems for efficiently increasing the wing area of an aircraft are disclosed herein. An integrated wingtip extension (310) configured in accordance with one embodiment of the invention includes a tapered wing section and a winglet (304). The tapered wing section (308) includes an inboard end portion (306) having a first chord length (L1) and an outboard end portion (306) having a second chord length (L2) that is less than the first chord length (L1). The winglet (304) is fixedly attached to the outboard end portion (316). The inboard end portion (306) is configured to be fixedly attached to a tip portion of an aircraft wing (302). In one embodiment, the tapered wing section (308) and the winglet (304) can be integrally formed from composite materials.

Description

technical field [0001] The following disclosure relates generally to airfoils, and more specifically to wing tip extensions of airfoils. Background technique [0002] Aircraft manufacturers often develop families of aircraft in which subsequent models of the aircraft are capable of carrying more passengers and / or cargo than earlier models. Increasing the carrying capacity of passengers and / or cargo is generally achieved by increasing the area of ​​the fuselage and / or wings. One prior art method for increasing airfoil area is illustrated in Figures 1A-2B. [0003] FIG. 1A is a top view of a baseline wing assembly 100 arranged according to the prior art, and FIG. 1B is a rear view looking forward at the baseline wing assembly 100 . Referring concurrently to FIGS. 1A and 1B , the baseline wing assembly 100 includes a baseline wing 102 and an airfoil 104 . The airfoil 104 is fixedly connected to the airfoil end of the baseline airfoil 102 . Although the chord length of the w...
