Blade pitch

Decommissioned wind turbines of the Kama'oa Wind Farm in Ka Lae/South Point, Hawaii awaiting removal, with rotors stopped and blades feathered.

Blade pitch or simply pitch refers to turning the angle of attack of the blades of a propeller or helicopter rotor into or out of the wind to control the production or absorption of power. Wind turbines use this to adjust the rotation speed and the generated power. A propeller of a ship uses this effect to control the ship's speed without changing the rotation of the shaft and to increase the efficiency of streaming fluids.
