Blade calculator

I have just put a simplified online blade shape calculator at http://windpower.org.za/bladecalcs/blades.php

It shows the ideal blade geometry for a given angle of attack. The default blade profile is the NACA 4412.

Its useful as a tool for understanding how Tip Speed Ratio and number of blades affects the optimal blade shape. Any comments/suggestions welcome!
