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!

No luck so far with the Goe 549. Michael Selig and his group have
data on their site for the Goe-417a

Lots of other interesting data for other airfoils also.

Good luck with your project,
