Can someone tell me where I can find more information on the design of a

Chris, what's a reverse NACA duct? My understanding is that they were
designed to work in one direction only, to bring in air with a minimum
of drag.

They don't work well, or at all, when placed on the fuselage or cowl
in a negative pressure area.

Thanks, Corky Scott


The concept is to place it in the airstream in such a way as to result in
negative pressure at the opening.
