Subject: [FlyRotary] Re: radiator size
Posted for Perry Mick <pjmick@viclink.com>:
Ed, I think I have the record for minimal number of cubic inches of rad
cooling a rotary.
The finned volume of my rad is only 12" x 14" x 1.5" (not including the
end
tanks). This is only 252 cubic inches. I also have a 1 x 3 x 9 cooler
plumbed
to the heater port for cabin heat, that is always on, only the heated exit
air
is controlled into the cabin. So that is another 27 cubic inches. Total is
less than 300 cubic inches.
It only works for me because I am producing relatively low power, 120 HP @
5200 RPM in climb. And I have ducted-fan assisted airflow through the main
rad. Should I produce more power in the future this will probably not be
sufficient radiator.

I'm trying to think of a canard pusher flying at the moment under rotary
power, using a conventional prop, that Paul Conner could use as a guide. I
can
only think of Ron Gowan's EZ that flew several years ago. Of course there
are
several Cozys etc. under construction, so there is still some trailblazing
to
do in this area. Fortunately for Paul, he can get a larger rad in his
plane
than I can get in mine.
