A few airfoil profiles from the extensive UIUC Airfoil Coordinates Database. The data is provided in a convenient x,y coordinate format suitable for plotting using PGF/TikZ's plot file construct.

Note that the data is released under the GNU General Public License. To use the data files with PGF/TikZ, you have to comment out the lines not containing coordinates.
