Low:

Just remember the R-1340 is a RADIAL!

Any radial sounds better than any flat engine. Turbine? Another "Teapot." A dinky little Warner or Jacobs, the Continental R-670 on your UPF-7, even a Kinner. I'll grant yoou hearing the exhaust over the mechanical clatter of the Kinner is hard, but it still has the radial sound.

Best one will always be the P&W R-2800,

Bill.

Ah yes, long live the radial engine, in all her many forms. May they rumble, clatter, and drip oil forever!

I can think of no other engine that truly has a "personality". And you are quite right... a -4 Corsair on a high speed pass with an R2800 opened up is a sound all it's own.

Even better than the Corsair with one R-2800 cooking along is the F7F with two. Or the old Curtiss C-46 Commando, it had a matched set of R-2800s also.

To go to an extreme we could even listen to the DC-6. That grand old girl had four of them stuck out on the wings. And the highest TBO of any radial ever, 3000 hours with the R-2800CE engines.

I miss the old days. All we get now are flats and teapots.

Bill.

Come to Alaska.

DC-6's are common...I see one at least once a day. :-)

Appreciate the invitation, but no, thank you. You also see snow every day, and your summers only last three hours.

Haw.

Don

Where are you in Alaska? I had a friend in high school who's dad lived in Anchorage. He was an avionics tech for North Star Air Cargo, and worked on DC-6s up there. That is truly one workhorse of a bird! Probably my favorite of the heavy recip transports.

I work at the old Air Force Base in Galena. It's about halfway between Fairbanks and Nome on the Yukon river.

Everts Air Cargo flies DC-6s in here almost daily both as freight and fuel carriers. They also fly C-46s. I have even seen a rare DC-7 in here now and then. It's great to see all these old prop jobs.

Don said the magic word. DC-7. I think the DC-7C, the "Seven Seas" model, was the ultimate. Even the L-1649 Connie comes in second best. And the only reason the Constellation series, whichever of the x49 versions, is in the running is its appearance. They were not a forgiving plane to fly, and Don Douglas' planes were all truly sweet machines.

Bill.

Yeah, I've heard stories about flying the Connie. Of course, the R4360's werent a simple engine to operate by any stretch of the imagination.

The only R-4360 installation we had any problems with were on the C-97 and KC-97, there was a resonant vibration around 1100-1200 rpm. They had a nasty tendency to convert the four bladed props to three blades.

And the Connies with the R-3350TC were another matter entirely. I don't remember ever having a flight of more than six hours that I landed with all four running. With the turbo compound engines the Connie became known as the "World's Fastest Tri-motor."

The R-4360 was big, complex, and brutal. But it was not the fuel hog the 3350s were, and when you wanted to leave those 28 cylinders would haul your butt out of Indian country really fast. Granted, the early C-97s with it had problems, but I don't know of any other application where the engine was a pain. Going 'way back, the Corsair F2G had it, the Martin Mauler was a failure but not because of the engine. And what I consider the best all-round propellor driven attack plane of all time had 4360 cubic inches of engine hung on its nose, the Douglas AD-1, our great old "Spad."

But my favorite radial is still the dinky little 18 cylinder R-2800. And I wasn't kidding about the TBO on the R-2800CE - 3000 hours in that DC-6B.

Bill.

The AD-1 had the 3350, Bill. I saw one last weekend.

I'm remembering the "Porcupine" engine. Maybe a different version? Really hard to mistake a four bank engine for a two bank.

Bill.

I have always thought the 4360 was in the Skyraider, too. But every online reference I can find says it was the 3350 (Good, higher engine counts means more parts for Rare Bear)

I did find one web page where they mentioned one experiment was done with a 4360 on the airframe...apparently wasn't too successful as it didn't go to production.

Anybody have an "In Action" book on the Skyraider to give more info?

Don

From the P&W site, all listed applications of the R-4360:

Classic
Engines

A four-row, 28-cylinder radial with the cylinders in a spiral arrangement, providing 3,000 horsepower initially, and up to 4,300 horsepower in later models.

Displacement: 4,360 cubic inches
Revolutions per minute: 3,990-4,300
Weight: 3,482-3,870 pounds
First run: 1941
First flight: 1942
Production years: 1944-1955
Engines produced: 18,679

Plane Popular Name Maker

XB-44 Super Fortress Boeing
B-50 Boeing
C-97, Model 377 Stratocruiser Boeing
XF8B-1 Boeing
B-377PG Pregnant Guppy Boeing
B-36 Consolidated Vultee
XC-99 Consolidated Vultee
A-41 Convair
XBTC-2 Curtiss Wright

C-124 Globemaster II Douglas
C-119 (R4Q) Packet Fairchild
C-120 Packplane Fairchild
F2G Corsair Goodyear
XF-11 Hughes
HFB-1 Hercules Hughes
R60-1 Constitution Lockheed
AM-1, 2 Mauler Martin
JRM-2 Mars Martin
P4M Mercator Martin
B-35 Northrop
XP-72 Republic
XP-12 Rainbow Republic

And the Spad isn't listed.

But checking the R-3350 I found this:

R-3350-23: 2,200 hp (1641 kW) with turbocharger
R-3350-26B: 2,800 hp (2088 kW)
R-3350-32W: 3,500 hp (2610 kW) turbo-compound
R-3350-34: 2,200 hp (1641 kW)
R-3350-85: 3,500 hp (2610 kW)
R-3350-91: 3,250 hp (2424 kW)

Douglas AD-1 Skyraider
Boeing B-29 Superfortress
Lockheed L-49/C-69 Constellation
Fairchild C-119 Flying Boxcar
Lockheed L-749/C-121 Constellation
Lockheed P2V Neptune

I added the "Bold" on the AD-1.

And I also saw a claimed MTBO of 3500 hours. Doubt any ofthem ever made it to that time. Just my impression/experience.

Sure thought I saw four rows in the Skyraider.

Bill.

I think it is the 3350 I was thinking about having all the problems instead of the 4360
