The technology can also be applied to downforce generating wings. Tests on a Porsche 996 GT3 RS suggested an 5 % increase in high speed cornering velocity.

On a downforce wing the technology is used to reattach the flow when a wing is angled to a degree that it separates. This creates more downforce than the unseparated wing as illustrated below:

The blue arrows are air flowing over the airfoil. The red arrow represent the negative lift generated.

When the angle is increased the amount of downforce generated increase and this is all within normal operation of a wing.

     What happens is that the flow over the wing separates as represented here by the blue arrows that no longer follows the surface of the wing. The wing stalls and generate an area of irregular flow represented by the red area behind the wing.

1)  By attaching Vortaflow this problem is solved. The flow is now reattached and the amount of downforce generated by the wing is increased beyond the limitations of normal flow.
