Vortex lift works by capturing vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge of the wing, is trapped by the airflow and remains fixed to the upper surface of the wing. As the air flows around the leading edge, it flows over the trapped vortex and is pulled in and down to generate the lift. A straight, or moderate sweep, wing may experience, depending on its airfoil section, a leading … Witryna21 maj 2015 · Wikipedia states: The Gurney flap increases lift by altering the Kutta condition at the trailing edge.
