Vortex Genarator

  • Description

A vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface, such as an aircraft wing  or a propeller blade of a wind turbine, or attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car. When the aerofoil or the body is in motion, the VG creates a vortex, which, by removing some part of the slow-moving boundary layer in contact with the aerofoil surface, delays local flow separation and aerodynamic stalling, thereby improving the effectiveness of wings and control surfaces, such as flaps, elevators, ailerons, and rudders.
