Allison B-17

Never said I liked it or disliked it. Just said it looked smooth. But
it ain't a B-17 without a radial engine!

Right, it's a XB-38!

BTW, does anyone know if were
there any land or sea applications for the radial motor or was it all air?

American tanks used radial engines for a while.
There was a small radial used for a ground generator, a guy
was looking for information about that one here not long back.
Back in the really long ago days I think there was even a radial
engined motorcycle, but don't place a bet on it based on my
say so.

I'm not aware of any Allison diesel engines used in semis. The Big
Three truck engine manufacturers are Caterpillar, Cummins and Detroit
Diesel. Going down the road, you can't differentiate between the three
by the sound alone and I suspect the high-freqency scream you're
referring to is simply the turbo.



They are in a lot of school buses, some semi-tractors & heavy equipment
but they're not as popular in semis as some of the others.
I've even seen turboed Allison V-8 diesels on pulling tractors; like
a bomb going off when they snapped the throttle open and shut.




I think those are actually Detroits, Allison doesn't make a diesel.
Most 92 series Detroits have a turbo and roots type blower in normal
operation. Big, ugly and dirty. Good for powering auxiliary wire
stringing equipment and motor torpedo boats. At least that's what an
old buddy told me was powering his Viet Nam river boats, a pair of
Detroits. The 71 series had the familiar blower you see on drag racers
and such. As far as school buses and medium duty trucks ( tow trucks
and such ) International is making a killing selling those, DT406's and
DT466's.

General Motors made diesels under the Detroit name and transmissions
under the Allison name for heavy applications. Confusion might come
from valve cover stickers that include both names when GM consolidated
operations.

Wow, looks like GM sold Detroit Diesel to Daimler/Chrysler. ( Or I
should say Daimler/Chrysler bought out Detroit Diesel. )

Well, the V-twin is basically a partial radial. I wonder if you
strapped a bunch together to turn a prop, would Harley sue you for
"stealing" it's famous sound? ( Like it tried to do to the Japanese
motorcycle manufacturer. ) But seriously...... I don't remember
coming across a radial on a motorcycle either. Hendersons and
Excelsiors with inline fours and sixes.

Aha! The 1893 Millet with a 1924cc radial. A 1922 Megola with a 640cc
5 cylinder radial. Here is a waste of a radial.
http://home.pacbell.net/geetumor/index_pic13.html Looks like a lot of
early motorcycles had three cylinder radials.

Good place to keep a spare. I'd hate to dust it or stub my toe on it.

Argh! Ya got me, Mike!
Yeah, the Diesels are Detroits. Of course,, you _could_ ig you were
willing to split hairs about it, call 'em Allisons after GM Merged
Detroit Diesel and Allison.
But that would be wussing out.

OK, I was having regrets having posted they were out there, I was
beginning
to wonder if I was thinking of Detroits.
But the neighbors' kid's hippie school bus has "Allison" written on it.
I didn't realize that GM had merged Detroit Diesel and Allison.

What about the Mazda RX7 (was it RX, or XZ or something!?) it ha (or had) a
radial engine!! Looked like the drum out of a washing machine!

A few light cars had radials (generally 3-cylinder) in the 1920s.
Bristol played with the idea of a 10-cylinder, two-row radial for
their post-WW2 venture into care production, but eventually went
with a re-engineered version of the pre-war BMW in-line 6.
One Fairmile D-type motor gunboat (MGB 5001, IIRC) was fitted with
four Bristol Hercules instead of the usual Packards, but actually
went slower because of the power absorbed by the fans providing
cooling. The intention was that she should have been the prototype
for a group of Centaurus-engined boats (which with 2500bhp/engine
instead of 1600 should have shifted), but the admiralty decided
(wisely, in by view) to go with ultra-high-power diesels (the Napier
Deltic) or gas turbines (the Bristol Proteus) instead of trying
to make radials afloat work. Having the tankage of 100-octane
they'd have needed aboard a gunboat was not an appealing idea..

When I think Mazda, I think "rotary" engine as in "Wankel".

Not at all the same as a radial, if that's what you were thinking.

Wasn't it really a "rotary"? A German Wankle licensed twin rotor?
