I would expect these to have the opposite effect - under the
fuselage/wings is
an area of high pressure, which would reverse the air flow. I believe
some
posters to this list have mentioned that air forced up into the tunnel
comes into the cockpit through the slots cut for the landing gear and/or
throttle. In some cases pilots have reported exhaust smell when flying
at higher angles of attack.
