What are vortex generators primarily used for on an aircraft wing?

Vortex generators are primarily employed on aircraft wings to stabilize airflow over the wing surface. They are small, fin-like devices that are mounted on the wings, and their primary function is to control the airflow around the wing, particularly at high angles of attack. By generating vortices, these devices help to maintain smoother airflow over the wing, delaying flow separation. This enhanced airflow stability can lead to improvements in lift performance, especially during critical phases of flight such as takeoff and landing.

The significance of stabilized airflow means that the aircraft can sustain lift more effectively, contributing to overall flight safety and performance. This aspect is crucial in preventing stalling, which can occur when the airflow separates from the wing surface. Therefore, the use of vortex generators directly supports better aerodynamic characteristics and flight operations.
