Hello Paul
In your script on cooling you refer to diagrams z, r, and s in relation
to heat exchangers at an oblique angle. Could you post them for me
please.

Ian Beadle

The curved one is figure r.
The wedge is figure s.

Can't find z :)

Hi Paul,
      These are the diagrams I asked for earlier, many thanks for the pics.
Could you also please clarify what is meant by "bell-shaped" in the same
article?. It would seem that both an internally "convex" duct & an
internally "concave" duct could both be described as "bell-shaped",- if I
make myself clear.

Yes you are right about that. I should not use the term "bell shaped". I should
say trumpet shaped.

There is no room in our airplane for a true trumpet shaped Kucheman & Webber
style duct unless it goes in the aft fuselage. The duct length needs to be
2.5 times the rad dimension.
