When the wind turbine blades have the same wind speed and included angle, is there a relationship be

Blade design is based on engine speed.

First determine the speed and power of the generator, then the size of the blades will be determined.

There is a formula for wind power generation: P=?ρ*π*R?*V?*Cp

ρ——air density;< /p>

V—— Wind speed;

Cp - wind energy utilization coefficient

If it's the same generator and you make blades of different sizes, of course, in theory, The generator with a larger blade area can operate at the same wind speed. Spin faster, because the power output P is greater at that time, as you can see in the formula above.

π*R? Here, R is the radius of the blade scanning area.

The principle is that you use the same engine.

Of course, larger blades are not better, as excessive motor speed would cause heat and damage.
