Clockwise, from top left:

1.) Rolls Royce Merlin (Packard) - Model V-1650-9
Bore x Stroke 5.4" x 6.0" , 1,649 cubic inches (27 liters).Compression Ratio 6.00:1 Supercharger type Two stage engine driven supercharger, Weight 1,690 lbs , Power 1735 bhp @ 3000 rpm 66" boost ...

2.) Lycoming XR7755 - Factory photo . This was an experimental 36 cylinder liquid cooled radial intended the B36, 7755cu in, 5000HP (7000HP was the development goal), bore 6-3/8", stroke, 6-3/4". Project canceled.

3.) Lycoming XR7755 (restored)


4,5) Pratt & Whitney R-4360 (Wasp Major): This 28-cylinder engine, nick-named corn cob, was the largest production piston engine ever built. First developing 3000 hp, it was improved to 3800(4300 hpsee below)3650HP model pictured. The 4360 was used in the Convair B-36, Boeing B-50 and C-97/Model 377 Stratocruiser and the fifteen ....

Pratt & Whitney R-4360 (Wasp Major), 28-cylinder, air-cooled radial arranged in four rows of seven cylinders each; bore 5.75 in., stroke 6.0 in., displacement 4363 cu. in., 3000 to 3800 hp. at 2800 rpm, weight approx 3600 lbs.

Many variants were made, some with fantastic technology (multi-staged superchargers, variable speed superchargers, multi-staged super/turbo charging, energy recovery turbines (re-powering the crankshaft), fuel injection, water/alcohol injection). One engine design, rated at 4300hp, was built and used on one wing of a test bed B36 using [turbocharger] exhaust throttling. The summit of piston aircraft technology, doomed by the jet engine.

Using the formula HP=Torque x RPM/5252 a 3800hp R-4360-63A at 2800rpm rates 7127 lb*ft of torque.
(and 2800 is peak HP not peak torque RPM).

Fuel consumption [for one R-4360 engine] at rated power is about 400gal/hr, or about 6-1/2 gallons per minute.

6.) Pratt & Whitney R2800 (Double Wasp), Cylinders: 18, Horsepower: 1800-2800, R.P.M.: 2,400
Bore and Stroke: 5.8 in. (146 mm) x 6 in. (152 mm), displacement: 2,800 cu. in. (45.9 liters), weight: 2,350 lbs. (1,068 kg) . Used in the F4U Corsair, P47 thunderbolt, P61 Black Widow, A26 Invader, Bearcat, Tigercat....

8.) Reno engine failure close up (note: cross bolted mains.

9.) Russian T34 Tank engine. Note overhead cams driven by shafts

Is that from the Dayton AF Museum? Everyone should spend time there.

Imagine being the flight engineer on a B-36. You'd have to monitor sparkplugs, magnetos, oil etc. for 168 cylinders.

Don't forget a transfer case to drive the steer axles, too!

:driver:

P.S.: Why did you choose the wimpy little 2,000 HP engine? ;)

P.P.S: The littler ones (including the corn cob) are air-cooled. I'm not sure about the larger ones.

DOH!!!!!! because I didn't read the fine print on the other pics.
We'll have to go with the big'un.

By the way..the engines on some big armored vehicles were air cooled but they had oil coolers to keep temps down. It would prob take a big fan to keep that monster cool in a ground application.
Never underestimate the power of a redneck with a shop full of tools, a welder and a warped imagination. :wink:

Wright Cyclone

Left- R-3350, Used in the B29, 2200-3500HP
Wright R-3350 - Wikipedia, the free encyclopedia


Right- R-1820, Used in B17. Also, used in the M6 Heavy Tank, as the G-200, a 9-cylinder gas-burning engine developing 900 hp @ 2,300 rpm . The Wright RD-1820 was converted to a diesel by Caterpillar as the D-200 producing 450 hp @ 2,000 rpm in the M4A6 Sherman Tank

Do you have any pictures of the type of engine (WWI airplane I think) that the jugs spin around the crank the same as the prop? I saw a display of one in San Diago years ago.. I never knew the jugs spun! I was telling Dave P about it and he gave a look like I was out of my mind.. I know they rotated because you could spin the prop on the diplay and watch it go around.
Thanks for posting these.. Man the engineering on some of them.. 200lbs in a 5lb bag..lol

Left -
WWII Daimler-Benz DB 605, inverted V12, used in Messerschmitt Bf 109, Bf 110, Me210. Also a coupled pair became the DB 610 (an inverted W24?), used in the Heinkel He 177...

Note the (Bf109 was equipped w/ 20mm cannon firing thru output shaft/spinner(in valley under the crankshaft).

second from left -
WWII Junkers Jumo 205, (2 stroke diesel) used in Blohm & Voss Ha 139, Dornier Do 18, Dornier Do 26, Junkers Ju 86, more info see-

http://en.wikipedia.org/wiki/Junkers_Jumo_205

Third from left -
WWII Junkers Jumo 004 (jet), Used in Messerschmitt Me 262 and Arado Ar 234


Right -
WWI rotary engine - Le Rhône 9C- 80hp(?), crankshaft is stationary and cylinders rotate with propeller. Uses no carb (thus no throttle control), Has a total loss lubrication system (oil pumped in crank end and washed away by fuel), poppet intake valve located in the piston, single pushrod for exhaust valve in head.

As I understand it, the lubricating oil used was castor oil. The combination of castor oil smoke and unburned oil spray from the exhaust would acquaint the pilot with the laxative properties of castor oil after extended flight. :shock:

This has made me contemplate how evil it would be to build a little rear-engine commuter car powered by one of these, and then proceed to drive it in bumper-to-bumper traffic... :twisted:

There was a time, WRT evil cars.. where a certain old plymouth had an extra windshield washer resivoir kept full of old motor oil, with a hose to the intake. Tailgater? Just press the button..

Wow! I always liked cutaways of pretty much anything. Takes a lot of work to make it, but it really is a lost art form and makes for a beautiful display.

I also like cutaways of rifles and pistols, but I'd hate to make one. Waste of a perfectly good gun!

The T-28 is my favorite single-engine aircraft. An ex-boss of mine has (had?) a T-28B, and I was lucky to be back-seat ballast on a number of flights before he moved up north. I had an opportunity to buy a flight in the back of a B-17G once, too. Naturally, that's my favorite multi-engine aircraft!
