Draw an airfoil

I need to programmatically draw an airfoil.

The airfoil doesn't need to be perfectly accurate, but just needs to _look_ like an airfoil.

Do you have any suggestions as to how I could do this? Is there a way to calculate all the points on the airfoil? (So, without predefining all the points myself, or just getting an image off the net, and drawing that to the display)..

Some sort of parametric equations perhaps? :\

Thanks

Here are some coordinates that you could store and when you want to plot it interpolate the points and scale to the size you want.

There are many different designs for airfoils which have different behaviours, you could choose one and just store the coordinates as above.

Awsome, thanks !
(funnily enough, the NACA 2412 is the airfoil who's Lift coefficient data I'm using :))
