SNACK-Super Numerical Airfoil Creation Kit - Version 1.4 The Super Numerical Airfoil Creation Kit (SNACK) is easy enough for science-fair projects, but powerful enough for PhD's. It makes airfoil generation and analysis as easy as clicking the mouse! Generate every possible NACA airfoil, Joukowsky airfoil, and more! SNACK will print any size airfoil to either a regular printer or plotter. Save coordinates in several popular formats. Most importantly, SNACK includes a Virtual Wind Tunnel to evaluate the airfoils.
