Reverse NACA duct

Would a couple of NACA ducts work on the bootcowl of a Taylorcraft BC-12D
to
bring in fresh cabin air? I understand a 337 would be required but would
it
do the job better than have to fly with the windows slide back? Just
thinking of better ways of freezing my feet off this winter. RTL


Oh, blasphemy and sacrilege! You would do that to the boot cowl of your
classic Taylorcraft?


Somebody's going to get this sooner or later and googling "inverted naca
duct" might bring something up. But my understanding is that the device
helps keep the boundary layer attached.

Can someone tell me where I can find more information on the design of a
reverse NACA duct?
