Pratt & Whitney R-4360 Wasp Major Cutaway

I was wondering what the crank shaft on a twenty-eight cylinder radial engine looked like. While visiting the Hiller Aviation Museum I found a powered cutaway model of the engine and several of my questions were answered.

The F2G Super Corsair has one of these engines while the B-36 Peacemaker had six and Howard Hughes' HK-1 (a.k.a. H-4 "Hercules," a.k.a "The Spruce Goose") had eight!

The Hiller Aviation Museum also had the nose section, including the cockpit mock-up, of the Boeing Super Sonic Transport proposal. For more information on the museum, see:

Yep..., I need to get more video on the Super Corsair flying.

Note: A similar video on a Wright R-3350 Cyclone Cutaway can be viewed at:

Man I LOVE the sounds of the engine racing in the backgroung. Great stuff.

Yep..., you can't have an engine like this with the audio of people roaming around in the background -- it just isn't done! I ended up extracting the audio from an Unlimited heat at Reno and pasting pasting it onto the video of this beautiful engine.

"Keep the dream alive!"

Doesn't the racing Sea Fury 'Dreadnought' have one of these engines too?

[paralleler]

Apparently so. I found the following on the web after Googling it: "Immediately after winning the Gold heat race on 14 September (at 426.122 miles per hour), Sanders declared a Mayday and safely put the racer down on the runway-after years of faithful performance, the big R-4360 had finally come apart, and Dreadnought was on the ground for the rest of Reno 1995."

in that aircraft it was installed?

[paralleler]

Yes. The F4U Corsair had a Pratt & Whitney R-2800 Double Wasp 18 cylinder engine. The plane in this video is a very rare F2G Super Corsair with the R-4360 engine. One of the intentions of the larger engine was to go after kamikaze aircraft but war came to an end before the F2G went into production.

The thing that amazes me is this is a engine from possibly the 1940's? And look at the craftsman ship!! Polished steel H con-rods Polished steel crank the works! These were built to be hammered and to be strong!! But i suppose yr not building to run 1/4's on Sunday they built them to defend our country's! Last thing you want is a rod thrown at 20,000 ft and in a dog fight. I have big respect to the men and women who built and designed them : )

[enginemasterbuilder]

that would be a challenge to rebuild. i wouldnt want to be the one doing it

[usabbott48g]

I want this video on my OT-808 unit.

[Acornoa]

how does this engine get lubricated?

[Bigfurry1975]

That would look killer in my Pontiac Sunfire!!!

[MOJONIXION]

This engine is also know as a "corn-cob" engine.

Nice video..!

The Aviation Technologies department at Southern Illinois University has an identical operating cutaway of the R-4360.
