Attached are a couple of photos of my lower cowling. It is minus 2 small
armpit scoops, and plus 2 larger scoops.
I notice that these scoops include the boundary layer with the air they scoop in. Isn't this a problem, especially near the fuselage?
The boundary layer grows at something like a 0.2 inch per foot of length. This rule of thumb would imply that you would need to space the side of the scoop about 3 to 4 inches from the fuselage. The upper lip should be something like 1.5 inches off the underside of the wing.
If you don't space the scoop away from the surface of the airplane, you create a lot of drag and you don't take in much air.
Perhaps there is some key point I'm missing.
