Easy to install,No modifications or trimming required. You just need your air deflector and keep your nuts ,then install new fairing side covers. When air flows around a moving object, it must accelerate because the flow path around the object is than length. For winglets, this accelerated flow around the curved nose of the fairing is an because the potential for generating lift increases in the square of the airspeed. It seems that the new concept is being applied to the downforce problem, that is, the vortex lift problem. In aircraft such as the F-16, the rotating vortex flows from the forward extension of the wing (called glove blades) back and forth on the wing. Such a vortex has a low pressure at core (a tornado is just a dangerous natural vortex). By reducing the pressure above the wing, it can be roughly doubled at a high angle of attack (for example, 30 degrees). This lift is not free, it requires power to push the angled and vortex system into the air.
