Webb23 aug. 2007 · In cruise flight, the vortilon sits below the attachment line and is thus lined up with the local flow. When the angle of attack of the wing increases and the attachment line moves aft below the leading edge, the vortilon suddenly sees a sdie flow, due to the flow along the attachment line.

Vortex Generators (VGs) can be used for various purposes such as changing stall characteristics, lowering takeoff and landing speeds and even reducing drag (typically on large transonic airliners). All of these effects result from the fact that VGs help to control and alter the boundary layer over a surface.

WebbThe vortex generator is a simple device to induce streamwise vortex for flow separation control, thus reducing the pressure-difference drag. The fundamental characteristics of vortex generators and the corresponding parameter influence are first introduced.

Webb24 maj 2024 · Downstream of the separation point, vortices often form, resulting in a turbulent flow. A flow separation is particularly dangerous on the wings of an aircraft, as this also causes a loss of lift and the aircraft is in danger of crashing. In aviation such a dangerous flow separation is called stall.
