Blade pitch control

Definition

Blade pitch control refers to the mechanism used to adjust the angle of the blades on a wind turbine or airborne wind energy system, influencing the aerodynamic performance and power output. By changing the pitch of the blades, operators can optimize energy capture under varying wind conditions and manage the loads on the structure, enhancing safety and reliability during operation.
