Lads, thank you all for the deluge of info and offers with my earlier request for
Radial engine info.
Before committing myself to the 285 Housai, can anyone say how well the engine
would cool
without any cowl, shutters etc.? My requirement is for an engine to propel a Fairchild
FC2 which
was a very old..late 1920's cabin monoplane and they had the uncowled Continental
220 hp
engines in the early ones. Authenticiy in the engine compartment is of some importance
to me,
but I know that some engines just don't do what the designer intended if one starts
to modify
the accessories that go with it...the cowl in this case. Thanks.

Folks,
How do I recharge my shimmy dampener (Yak 52) without the special tool ? I
am sure that one of you bright folks will have figured this out.

Don't do it. The cylinders are designed for pressure cooling. If you don't
have the proper baffling you will get hot-spots on the cylinders and shorten
cylinder life. You might be able to get by with just a "speed ring" type cowl.
OTOH, a couple hundred hours may be sufficient for what you want. You might not
care if the engine goes to 1200-1500 hours.

Thanks for the point of view, Brian. I was afraid of that. There is no way I'd
build and fly a plane
anticipating only a few hundred hours of useful like. I plan to use this plane
like a motor home
and do a North American tour. (USVI later?...is Sparky's Waterfront Bar still in
existence ? )
A speed ring is something I could live with but a full cowl wouldn't do at all.
I going to have
to dig a little deeper before settling on an engine. I suspect that the baffles
on the Housai are
wedge shaped items which direct air thru the cylinder fins only, so if I installed
them and a
speed ring, I might achieve everything that should be in place except for the front
shutters.
Aesthetically, I could live with that. Could thermal shock cooling be managed up
in the frozen
North without the baffles and a tight cowl?
Thanks.

In regards for an engine to propel a Fairchild FC2
Why shouldn't he do this installation? Aren't different engines used in
hundreds of different applications? Seems to me the best possible
arrangement of cylinder cooling would be to stick it out into the high
velocity airstream. Hot spots with a high heat conductivity aluminum
cylinder positioned in high velocity air? I doubt it. He's more likely
to have a problem with overcooling.

Yes. Red Hook, American Yacht Harbor, slip D-3. I usually keep Guinness in the
fridge but I also keep the making for Rum Punch and Painkillers around.

It is a potential problem. I flew my CJ without gill louvers for four years and
about 700 hours with no apparent problems but I lived in Central California.

I recommned you check out the difference between pressure cooling and flow
cooling. They are very different. Stagnantation on the front and rear of a
cylinder designed for pressure cooling creates big temperature differentials
within the cylinder and head which ultimately leads to early failure.
But I am either right or I am wrong. Seems to me that if you disagree with me
you would want to go do your own research to determine the accuracy or
inaccuracy of my statements.

In this regard it makes no difference which radial engine you choose. You
either use a pressure cooling system which includes cowling and
intercylinder baffles or NONE of the above.
The FC2 and many others were before the NACA cowling and were simply air
flow cooled. That still works.
The Townend Ring was the first attempt to reduce cooling drag, not for
improved cooling but for increased airspeed.
The NACA cowl served both ends.
So if you want an authentic look-- do it. Just make sure you do not use the
baffles.
