hi

I am trying to design a 518 w horizontal axis wind turbine with 3 blades. The blade length is 1 m and the average wind speed is 7.8 m/s and I have divided it into 10 equal lengths (10cm,20cm,…100) to find some parameters like local design speed chord length, twist angle …etc. But, I’m struggling how to find the chord lengths and twist angle. I have chosen NACA 4418 airfoil, tip speed ratio=6, Cl=1.2009, Cd=0.0342, alpha=13

can someone help me how to calculate it please?

i need the formula.

thanks.
