Milt,
I just returned from vacation and saw your posting on the Rocket list.
I'd like to do a test of blocking part of the airflow and seeing what
happens. It would be very interesting indeed!
I've got a camera mounted in the inlet already. Tufting the airflow
shouldn't be that hard to do! Finding the time to do it is another
thing!

| Subject: | Re: cooling airflow |
If a center divider works out, what about some baffling attached to it to
divert some of the (presumed) forward flow along the engine upper
centerline, down and over the cylinder bases? Might be an interesting
experiment. If much of the cooling in-flow is being diverted by the aft
baffles back toward the front of the engine rather than down through the
cylinder fins, giving that flow (especially as it will now be slower),
another chance to go where you want it might work. You have 200+ knot
airflow coming in the cooling openings being slowed to near zero at the rear
of the baffles and rerouted forward. Might not be too hard to get some
"thermal work" out of it...
