The Gottingen 549 Airfoil is used on many sailplanes, including my
Cherokee II. For my aerodynamics class, I am developing a FORTRAN
program to use the panel method to determine aerodynamic coefficients
for an airfoil. Part of the exercise is to first pick an airfoil with
known coordinates and with available wind tunnel or other experimental
data so that we have something to compare our final answer. I would
obviously enjoy using the Cherokee's airfoil for the project, but can
not find any experimental data out there for it. Any suggestions?
Thanks!

Coodinates and wind tunnel data for the Gottingen 549 airfoil is
included in "Comprehensive Reference Guide to Airfoil Sections for
Light Aircraft (c) 1982 by Aviation Publications, Appleton, WI
Good Luck

Steve - THANK YOU!

Got the book today. Interesting that the wind tunnel data is from
1926!
