The winglets were developed by Learjet in the 1970's. The early Learjets had
almost straight wings. They were looking as swept wings as a means of
increasing their efficient high mach cruise numbers.
Swept wings at high speeds tend to have the air turn and slide down the wing
instead of flowi
I always thought NASA did all the research on the winglets and that Burt
Rutan was the first to put it into use. Lynn

Correct me if I am wrong gang but I have always been taught that winglets were
designed by NASA to reduce/eliminate induced drag caused by high pressure air
attempting to flow around the wingtip instead of smoothly out the trailing edge
from the underside. These wing tip vortices cause disrupted

I have watched the discussion about winglets and thought a little
information might be helpful.
The following was scanned from the textbook
Aircraft Design: A Conceptual Approach by Daniel P. Raymer, American
Institute of Aeronautics and Astronautics
and run through an OCR program:
Wing Tips

Hey, maybe Troy Petteway's plane will have a little mishap requiring him to
rebuild his wings again, and we'll see the winglets?! However, the guy
Hi Oscar,
Ashok Gopalarthnam, who designed the new KR airfoils, developed a
program much like what he used to design the airfoils to design the
contours of intersecting surfaces. An example that he used in his paper
was winglet design.
I would love to see him do his magic on the wing fuselage
Steven Eberhart--
Thanks the specific and pertinent information about the design of wing tips.
It helps to understand what I am trying to do, and information like this will
point me in the best direction.

what effect would 2 ft/wing extension combined with the xx46 modifaction have
on a standard length kr 2 sporting a corvair?
2 f/wing extension will clearly reduce both wing loading in lbs/ft2 and
safe G loading. It affects lifting capability and stall speed. The Corvair
adds weight over the VW. To get the same stall/approach speeds for a given
payload, you need more wing.
