Delaying the Stall of A Low-Wing Aircraft Using A Novel Powerful Vortex Generator
Inventions, 2022 In this study, a new aerodynamic surface concept is introduced, which is a powerful vortex generator (PVG). It can delay the stall point in a low-wing aircraft. This delay leads to a significant increase in the CLmax of an aircraft.
