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 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

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

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. Will Rogers once said, "We're all dumb, only in different areas." I don't know where it

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. At 08:35 AM 9/4/2003 -0400, you wrote: >what
