I am much obliged to you for your answer, sir.

Thanks for your opinion, sir. My airfoil are symmetrical about the horizontal axis, the picture just shows only half. Sorry, my English is not very good. If the above formula does not apply in this case. Can I use other factors to calculate rotational speed with the existing unload rotational speed?

Just another question, sir. In Well Turbines situation, Is the above method still valid? This is my blade airfoil below. Thanks for your attention.

Thank you very much for your answer. It is very helpful for me.

Hello everyone, i have a question, how to find wind turbine rotor rotation speed based on freewheel rotation speed of rotor (RPM)(torque = 0)? Thanks for your attention.
