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.
