An example of a general purpose airfoil that finds wide application, and predates the NACA system, is the Clark-Y. International Journal of Engineering Research and General Science Volume 3, Issue 2, March-April, 2015 is to analyze airfoil at different of Engineering. The data is provided in a convenient x,y coordinate format suitable for plotting using PGF/TikZ's plot file construct. gif\ \ \ Low.
