Wind Turbine Blade Design

As the speed at the tip of a rotating blade is faster than it is at its root or center, modern rotor blades are twisted along their length by between 10-to-20 o from root to tip so that the angle of attack decreases from where the air is moving relatively slowly near to their root, to where it is moving much faster at the tip. This blade twist maximises the angle of attack along the length
