Boeing Raked Wingtips

Thu Sep 01, 2005 5:18 am

while Aviation Partners is the company behind the blended winglets used by boeing and other manufacturers, who do the raked wingtips belong to, if not boeing?

Boeing holds the two patents on raked wing tips. They are US Patent 6,089,502 "Blunt-Leading-Edge Raked Wingtips" and US Patent 5,039,032 "High Taper Wing Tip Extension".

The 787-8 and -9 will also have raked wingtips, as would the 747Adv.

The idea of raked wingtips is associated with something called the Schuemann Planform. From my understanding, the Schuemann Planform is a set of aerodynmic priciples and rules regarding the design of a wing according to some guy named Schuemann. How strictly Boeing conforms to this planform I don't know, but Airbus has used ideas from it as well in the A310/330/340 (all aircraft who also utilize the raked wingtip. Google it, maybe you'll learn something.
