Tony;

Technically not an airfoil.  An airfoil is solid with free stream =
flowing
over the surfaces.  The interior of a duct, flow constrained and =
strongly
influenced by the opposing wall is quite another ball game.

Subject: [FlyRotary] Scoops

can anyone shed some light? Is there an airfoil that makes up the scoop? =
and
if so can we use different airfoils to get the desired cooling results =
say
in a climb or unusual attitude. In other words can you stall the air =
going
into the scoop. Or am I way off base here?
