Hi Paul,
Really enjoyed the talk you gave at
scaled last week.
Im in the middle of building new
radiators for my olds powered tailwind and one of your
comment on radiators I have not found info on?
That is isolating the counter flow
radiators thermally? Is this in the compact heat exchaners
book? I have not found a reference to it?
Thanks
Tom Siegler
No. The book Compact Heat Exchangers is all theory. No drawings
of practical applications.
I invented this specific configuration based on the theory in
book. I just makes sense
to isolate the input and output tanks thermally. Some people
have tried to copy
the idea and welded the tanks together defeating the effect. I
use wood to isolate
the two cores and the tanks.
I works however!!! :-)
The Tailwind V8 is inverted so there may be room under the
engine.
If you have room under the cowl you might be able to raise the
V8 thrust line to give a little more room underneath..
Not only is the Wankel very light for the HP it is
also very small for the HP :-) With a normally aspirated p-port
engine you can get
250 HP at 7000 RPM.
Here is another configuration we call the quick and simple. The
bottom of the
fuse is part of the diffuser. It adds a bit to the frontal area.
One can actually see the heat flowing out of the bottom of the
rad in
this fantastic air to air photo.

Tom did you get a copy of my book at Scaled?
I would like to see your airplane. Where is it?
