pitch at blade tip
1Blade pitch — or simply pitch refers to turning the angle of attack of the blades of a propeller 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… …
2blade twist — i. The undesirable variation in pitch from root to tip caused by aerodynamic loading. ii. The twist built into a propeller or rotor blade. In the case of a propeller, it is to ensure that the pitch angle at the root is greater than the tip. In… …
