Guest Posted February 23, 2014 Share Posted February 23, 2014 “Platform aerodynamics, I think, made the difference between the American boat and the Kiwi boat.” Tom Speer, wing designer, Oracle Racing “The slot allows you to go to a higher maximum lift because of the behavior of the boundary layer, which is where all your skin-friction losses occur. The boundary layer is thin, but it wants to get stuck to the wing and not move. Meanwhile, at the leading edge of the wing, the pressure is very low. Toward the trailing edge, pressure increases. There is a tendency to push the boundary layer toward lower pressure—push it forward on the wing—and that’s where you get flow separating from the surface and a big dropoff in lift. With a slot-and-flap arrangement, you are basically dumping slow air from the lead element into high-velocity air around the flap. Or, let’s say that you are taking one bottom layer and handing it off to a fresh bottom layer on the flap.” more here http://blueplanettimes.com/?p=11988 Link to post Share on other sites
