Speaking of NACA scoops...
Supposedly NACA scoops don't work in low pressure areas and the area
that the scoops are being put into is a low pressure area -
But, has anyone really checked to see if it that area on top and just ahead of
the firewall _is_ low pressure? I mean, by the body shape, it should be, but
the prop may be greatly influencing the flow across the rear of the aircraft.
Would a tuft test tell, or would it only tell if we have attached/detached flow?
For a water cooled installation, NACA's on the bottom might be a good
alternative to a P-51 style scoop.
