Adjusting the angle of attack is crucial for maximizing wind turbine efficiency as it directly influences aerodynamic properties such as lift and power. The angle of attack refers to the angle between the blade’s chord line and the relative airflow.

As wind speed increases, the angle of attack needs to be adjusted to maintain optimal performance. Higher wind speeds require a smaller angle of attack to prevent stalling and excessive drag. On the other hand, lower wind speeds require a larger angle of attack to generate enough lift and power.

Additionally, the impact of blade shape on wind turbine efficiency cannot be overlooked. Blade shape affects the distribution of lift and drag forces, as well as the ability to capture and decelerate wind effectively.

Therefore, optimizing the angle of attack and blade shape is essential for achieving maximum wind turbine efficiency.
