Q-80: I know years ago that you could purchase books containing coordinates for plotting most known wing airfoils. I’ve heard that information like this is now available on Web sites. If that is true could you steer me to a particular Web site to get me started?
A-80: The airfoil program that comes to mind can be found at
www.profili2.com/eng/default.htm. At one time the Profili airfoil program was
available as “freeware.” From what I understand, it is now offered on a trial
basis for free, but after a limited time you have to register and pay a fee.
I just called up the Web site and found that many new features have been added.
The claim is that the program now includes more than 2,200 airfoils. It ties in
easily with automated-drawing-type programs.
If you are interested in model-aircraft design, you might want to look into this
program. I suspect there are others available, but this is the one I know about.
