The basis of all science is observation (and experimentation), right? Once you learn to keep your eyes open, you will see many things which you would normally not.

I did not plan nor expect this to happen, but when I was walking toward the truck that morning I had a hope, and that hope was confirmed.

Boeing 737 Advanced Blended Winglets

As The Croft Flies: December 2010 Archives
#MEBA10: Winglets 101
By John Croft on December 6, 2010 12:36 PM

Walking the ramp here at the Dubai International airport on the eve of the Middle East Business Aviation (MEBA) show, I happened on a good example to show the difference between blended winglets and elliptical winglets.

Blended winglets are the intellectual property via patent law of Seattle-based Aviation Partners..

Elliptical Winglets are the intellectual property via patent law of Wichita-based Winglet Technology, the founder of which used to work for the former.

Needless to say, they don't like it when you get the two technologies mixed up, despite the fact that both increase maximum load and increase cruise range.

So here's the deal:

Blended winglets as seen on the Boeing Business Jet (B737) in the background consist of a straight winglet joined to a straight wing via a curved joint.
Elliptical winglets, shown in the foreground on a Cessna Citation X, consist of a constantly curving winglet joined to a straight wing.
