Main Question or Discussion Point

hi!...
Does anyone know the relationship (i mean formulas) relating to the incoming air velocity to the rpm of a wind turbine?..i need to have a design in the generator part and also the parameters of the propeller..thanks!

best regards, :)

The speed of the turbine would depend on the blade design and the wind speed, you are looking at this the wrong way round, start with the mean wind speed you expect, decide what speed you want the turbine to rotate at and then design your blades.

It's related to the size of the turbine and the lift to drag ratio of the blades. There isn't a simple relationship - you have to know how big the turbine is and what the characteristics of the airfoil are. The best place to start is the aerodynamics of the turbine blades.

thanks for the reply :)..do you have an idea on the blade design?..or just a simple design?..
