Question

In general, how does blade stalling typically affect lift and drag on a rotor blade?

Accepted Answer

Blade stalling significantly reduces lift and dramatically increases drag on a rotor blade. Stalling occurs when the angle of attack of the rotor blade exceeds a critical angle, causing the airflow over the blade&#x27;s upper surface to separate. This separated airflow disrupts the pressure distribution, resulting in a loss of lift. At the same time, the turbulent airflow creates a substantial increase in drag. The stalled blade becomes much less efficient at generating lift and experiences a significant increase in resistance. This imbalance can lead to vibrations, reduced control effectiveness, and, in severe cases, loss of control.
