Assuming that the DC3 had Curtiss-Wright R-1820 engines, they had prop
reduction gears.

| Subject: | Arnie's 560 Commander |
Hi All,
This is probably more of a question for Sir Barry, but I thought it might
also be of general interest:
I just got my October/November copy of Private Air magazine, and their cover
story is about Arnold Palmer and his history with private aviation. Of
interest, the article mentions that he once leased a Jet Commander, but
before that, and more importantly to us, he owned a 560 Commander. There are
three black and white photos of the 560, including one interior shot with
Arnie sitting in the pilot's seat. The caption that accompanies the photos
mis-identifies the 560 as "the hefty Rockwell Jet Commander"(!)
What became of that 560?
Regards,
Stan

Aren't all OR most round engines geared? At least that was my
impression.

Good Evening Don,
Most all of the larger ones are, but the ubiquitous R-985 and R-1340 are
almost exclusively direct drive.
There were a very few 985s that had gearing. Not sure if they were
certificated or not, but at least one 985 with gearing for the propellor was used
in
a racing version of the Beechcraft Model 17.
A high percentage of the 1340s were geared. Many of them were used in the
Boeing 247 and the Nordyn Norseman, but the 1340s in all the production Harvards
and Texans were all direct drive though many have had geared versions
installed.
That nice little Russian engine is built both ways!
As Always, It All Depends!
Happy Skies,
Old Bob

That's very nice, Milt.
Did you notice how far BTDC the ignition fires? I was looking for valve
overlap but the footage cuts at the precise moment that it should happen.
Although there is one frame where the inlet valve starts to open while the
exhaust valve is completely closed, indicating that his particular engine
doesn't have valve overlap. That technique to increase power without any
penalty somewhere else, has been developed in the late 60's or so and then
only in very exclusive high-performance engines. My guess is that this
engine is of a pre-1960's design; it is probably an aircraft engine.
