Not that I would even know how to implement something like this, but I do like to learn as much as I can. After reading the last 10 pages it seems like these air curtains work by moving air from the higher pressure area in from of the vehicle (bumper area) through slots, and increasing it's velocity by narrowing the slots into slits before expelling the air across the face of the front wheels. This in turn either helps fill the cavity of the front wheel well causing a "boundary" so that the air moving around the vehicle doesn't get "scrambled" causing drag? Or the air coming through the slits is of a greater velocity (pressure?) than the air moving around the corner (bumper) creating this "curtain", again keeping the attached air from getting "scrambled"?

I am assuming these slits have their opening in the wheel well somewhere near the vertical mid-line of the tire or are they closer to the outer edge of the tire?

I know the "particulars" of this are way above my head, but man I do love to learn.
