The 757, like all current commercial jet transports, uses a supercritical airfoil section. The exact definition of that airfoil is probably considered proprietary. However, there is no reason you can't ask to see if the company would give you something close. Try a letter on your official letterhead stationery with an enclosure describing the project. I'll find you a name and mailstop if you are interested. The public data are as follows: Aspect ratio 8.4 (trapezoid) Span 124 ft 6" Wing area 1951 sq ft (reference) The 757 has never had a winglet. -- Terry firstname.lastname@example.org "Anyone who thinks they can hold the company responsible for what I say has more lawyers than sense."
