Well Todd, we have the bend canard too :) now all I have to figure out

is..what the heck is a P-51 type scoop with boundary layer air bleed? Does
anyone have some good pictures, formulas, data etc for configuring these
things?

Surely you have seen pictures of a P51 Chrissi?
Don't copy the duct however. It is wrong! You will need an opening
at least 20% of the rad area and a very large opening at
the rear of the airplane to let the air out. Twice the inlet area
at least.

I would guess the boundary layer to be at least an inch
thick at the back of a canard. What say you Al Gietzen?

Chrissi,
Your good for a laugh, when you feel like it !

Of course Paul is the expert here, but from a laymans point of view,
a P51 Scoop is 1" radiused edge (if I remember right)  opening
of desired  size , with the opening completly seperated from the
fuselage by a flange (which joins the scoop to the fuselage).

The flange is approx 1" deep or a little more (to push the scoop
down below the boundary layer) the flange area is concave sided
and front with a radiused leading edge.
I hope that helps !
