Thank you Umran. I appreciate that this work is for students thesis.

Now that I know that you use true pitch (foil centerline pitch) and translate it to angles I can check my graphs, not by iterations, but by plotting single conditions, and manage my rule of thumb formulae to closely resemble these plots. Bear in mind, that my work is more of a practical nature than scientific. It is the results that count, not the road toward those results. I guess that for you, the road is more important?

I will try to make a single speed simulation with known engine (rpm/power curve available) from static to max speed using a Clark-Y modified foil. Give me some time to work on it.

PS
for airfoil simulations I use the Profili computer program by Stefano Duranti. It is worth every penny I spent on it, and he is always very helpful when I need a new computer installation code. www.profili2.com
