The last of the big radial powerplants from Pratt & Whitney long past was the huge P&W 4360,28cyl,turbosupercharged,water injection air cooled 3500HP hi tech engine. This baby was awsome to see & hear run,while turning a 16ft 6in Hamilton Standard,full reversing,feathering propellor. The Berlin Airlift Historical Foundation from Toms River NJ. has one of the last remaining examples of the big prop era still in operation today. 4 of these big P&W 4360's turn in unison and is quite a site to behold. This group ownes & operates one of the last existing boeing C-97 STRATOCRUISERs in the WORLD today. When complete SHE will become a Flying Museum of COLD WAR HISTORY.See us at www.spiritoffreedom.org "The Legacy Lives On"

I worked in the overhaul facility of the Wright 18-cylinder turbo-compound used on the Argus maritime recon aircraft. This was back in the 60's, when I was a college student. It was exhilirating to run the final test, with the engine mounted on a fixture with the big props, running rich belching fire....

Reedyreed, thank you for the information. Where exactly is the C-97 based? I read in that webpage that it arrived at Milville in November. I'd sure would like to come down and take a look at it!
I had the pleasure of seeing the foundation's C-54 a few years ago at the Milville airshow. I was working with this boy scout group at the airshow, and I remember the C-54 doing a fly-by for us before heading home. It was a great gesture very much appreciated by all us youngsters!
PPGMD, what's special about these engines is that there are very few left running in the world (you could probably count them with both hands and have fingers left to spare). It's a four row radial engine, and I could only imagine how nice these things sound!

Reedyreed, You may be interested to know that you can see a photo of a cutaway 4360 on the aeromuseum.org website for the Octave Chanute museum. The accompanying text gives a rundown on the aircraft that carried this engine. Some aircraft originally had the Wright 3350, but were later modified to fly with the 4360. Lycoming had an experimental XR7755 radial engine of 5000 hp, but I find no evidence it was ever in production. A good friend of mine rode a C-124 to Viet Nam, and he told me they stopped at every island in the Pacific and changed all the spark plugs. And at 224 plugs per plane, that was no small task. Regards,
