Wind Turbine Speed | TurbineGenerator

The linear speed of the wind turbine varies with the blade length, and also varies at different points on the same blade. Here’s why: Linear Speed of Blade = distance traveled / unit of time. Since the distance is measured as the circumference: Linear Speed of Blade = circumference / unit of time = (2 x Pi x Radius) / unit of time. Since the radius is the longest at the tip of the turbine it is the point of the blade with the highest linear speed.
