Introduction The relationship between the length of the wind turbine blades and the effective upwind area is that the area is the swept area of ​​the wind rotor. Do you mean that the wind wheel doesn't actually occupy the entire area of ​​the circle at the same time?

The relationship between the length of the blades of a wind turbine and the effective windward area

Yes, the area is the area swept by the wind wheel.

You mean the wind wheel doesn't occupy the entire area of ​​the circle at the same time? Actually, it doesn't matter. This effect is included in the conversion efficiency.

The formula for calculating the power of a wind turbine is:

P=cp*(0.5*rho*(v**3)*pi*r*r)< /p>< p >cp is the conversion efficiency 0.2

The calculation shows that r is the length l of the blade you mentioned is 9.9348 m
