Which component's effectiveness is maintained by vortex generators during extreme angles of yaw?

Vortex generators are small aerodynamic surfaces typically mounted on the wings of an aircraft that help manage airflow, particularly at high angles of attack or during extreme yaw conditions. Their main function is to improve the effectiveness of the aircraft's control surfaces by preventing airflow separation.

In the context of maintaining control during extreme angles of yaw, the rudder is particularly important. The effectiveness of the rudder is crucial for directional control, especially when the aircraft is subjected to significant yawing moments. Vortex generators enhance the flow over the rudder by generating vortices that stabilize the airflow, preventing it from becoming turbulent and helping the rudder maintain its effectiveness in providing the necessary aerodynamic force to counteract unwanted yaw motion.

This is particularly relevant in situations where aircraft may experience significant sideslip or a need for coordinated flight in a turn. By embedding these devices, the pilot retains better control over the aircraft, enhancing safety and performance during challenging flying conditions.
