Pratt & Whitney R-4360 Wasp Major Cutaway

[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.

[PERIZ99]

Nice video..!

[fastpilot]

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

[cutter043]

this is a awesome engine .. if yu like go to facebook look up CHRISTOPHER DOFF-SOTTA , ( me ) go to my pictures look for my pictures of the boeing museum in seattle. i was there for 9 hrs last yr . i thought i died and went to heaven.. anyway they have a cutaway of the corncob and they also have the super corsair.. that goodyear built... please enjoy the pics i got just about everything i could think of on the facebook website... i love and worship these planes...

[lotanerve]

Not bad for slide rules!

[elebeu]

Wonder what the lift and duration specs. are on that cam ring.

[TownBranchDandy]

You must not forget, Silver was one of the material used in the connecting rod bearings on some of the WWII vintage Radials. A small fortune just in bearing material. Sodium filled Exhaust Valves. I have a feeling that the Super Corsair swallowed a valve. Sodium is highly dangerous Also sodium when it comes into contact with water, produces hydrogen gas, very explosive. I you want a real work out that beats the gym, start torquing the cylinder mounting flange fasteners.

[FarrarMax]

There is a similar powered cutaway model of the R 4360 engine in the Evergreen Aviation Museum in McMinnville, Oregon, right next to the Spruce Goose.

[antienjigglement]

I saw a static cutaway at the air and space museum near Omaha. That place is worth seeing. Anyway it is gratifying to see a moveng cutaway especially with the reduction gears and cam gear.

[DARKSCOPE001]

we have an engine very close to this ours has the power recovery turbines on it tho neet idea but as far as i know it never worked. anyways that is a beautifull engine ours isnt nearly as good of shape its all tarnished but still a work of art

[scscotto]

The Miami Space and transit Museum used to have this very same cut away model in the display area to view.I saw it many times growing up and had to do a plug change and timing on a 2800 for my Powerplant certification.The biggest Radial ever produced.

[justwatchinguc]

Auh Yes... Nothing like the Symphony of a round motor hitting on them all..less of course your behind her ..throttling her up...oh my...that's gotta be better that sex......or darn close... :-)

[quigley257]

Engine displacement was 4,362.50 in³ (71.5 L), hence the model designation. Initial models developed 3,000 hp (2,240 kW), but the final models delivered 4,300 hp (3200 kW) using two large turbochargers in addition to the supercharger. Engines weighed 3,482 to 3,870 lb (1,579 to 1,755 kg), giving a power to weight ratio of 1.11 hp/lb (1.83 kW/kg), which was matched by very few contemporary engines.

Wasp Majors were produced between 1944 and 1955; 18,697 were built.

[Shalinar45]

From what I remember from talking to a guy in Chino, where this plane is based, these are very tempermental BEASTS to run.They don't like to start if you do something wrong...

[flipmodeOptimus]

Fantastic video good job!!

[gnrfan32]

my gosh, imagine all that work, calibration, & all the equations required to have this thing made??

im sure it was all worth it to defend our country, but imagine a plane hauling this monster getting shot down.

must be a waste of intense labor.

[MOJONIXION]

Other way around. This engine Hauled a BIG Plane . B36 bombers

[isamike]

a thing of beauty

[MrGuvEuroman]

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 : )

[cutter043]

i like what bagheera says.. THE SWEET SOUND OF 3000 HORSEPOWER. all those cylinders. my lord what sound.. thats worth risking your ear drums for .. lol

chris

[stormrider62033]

The b-36 peacemaker had 6 of these huge engines on it

[enginemasterbuilder]

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

[Xenophoebus]

How many rotates per minute it gives at 2000 hp?

[Robkat3751]

Ohhps, just read the header. Super Corsairs for one. That is a lot of engine for one plane, amazing. I would have expected two or four in a bomber of some type.

[Robkat3751]

Which airplanes would this have powered?

[ziggassedup]

nice vid dude.theres a lot of shit going on in that engine..masterpiece.:-)

[Bagheera2]

Ahh the sweet sound of 3000+ horses........:P

[JGMagoo]

C-97 Cargo Transport and KC-97 Refueling Tanker also used 4 of these. I think, about the largest displacement reciprocating aero engines ever built. I'v seen that cutaway. A work of art indeed!

[ilard4]

Their is also another working cutaway engine at a museum in central Florida, called Sun n Fun museum at Lakeland Regional Airport. A small museum representing some interesting military and civilian pieces, all under cover.

[paralleler]

My apologies to someone. I meant to delete one comment but accidentally removed two. Sorry.

Paralleler

[dzanicjasmin]

I wonder what this engine sounds like.. wow 4 rows of radial engines put together.

[88SC]

Crap! That was supposed to be in response of dzanicjasmin wondering what they sound like.

[IK1963]

Turn your sound on mate!

[totenkopf999]

there is no replacement for displacement. a work of art.

[john4612]

I think there is another powered cut-away one in the San Diego aerospeace museum, and also a British Bristol Centaurus radial engine there

[maplelaffs]

too cool 4 words

[Irvine5312x6ma]

Now I wonder how the heck should the Wright XR-2160-3, destined, at a time, to be fitted on the Republic XP-72, should look like...it had 42 cylinders, my goodness!!!! This engine is mentioned in the book: "War planes of the second world war", Fighters, volume 4, by William Green, 1961.

[88SC]

The XR-2160 "Tornado" was destined for the Republic XP-69, an entirely new design. If you want to see more of the Tornado, search up the Weakforce Press website; it's on their homepage.

[Irvine5312x6ma]

Thank you very much!!!!! :-)

[Irvine5312x6ma]

And, paralleler, the Lockheed Constitution, the Boeing XF8B-1, the Republic XP-72 had this engine as well!!! I know, there are more planes equipped with it, but every single aircraft that had the R-4360 performed well... could you imagine the F7F Tigercat with 2 of them? No other plane could beat it at Reno!!!

[Irvine5312x6ma]

Cuz I'm a Tigercat fan, anyway!!!

[boxr4]

Great Vid. Good close-ups of the relationship of auxilliary rods to the master rod in each bank, shows cam plates and turbine housing.Leaked and burned a lot of engine oil.Maybe a vid somewhere of the prop shaft gear reduction and pitch control.

[cyanidecn]

They have another working model exactly like this model at Museum of Flight @ Boeing Field it's just like this one and at the Smithsonian National Air and Space Museum Annex in Mananas Virginia but it's not moving but a great cutaway

[ValiRossi]

Amazing technology for the time.

[100thbombgroup]

That is one heck of a good areo engine and fab cut away model.

The sound is like a dream.

Thanks for that.

[yellowchthonic]

Truly fantastic. It must be a total nightmare to work on. Probably got 4 dizzies?

[GGigabiteM]

I read somewhere that for every hour that it was in service, it had to have 3 hours or more of maintenance checks per engine. The R4360 also had bad problems with crank case oil leaks on the bottom cylinders leading to black streaks on the wings which made them unpopular on airlines.

Though while in the air, they were notoriously reliable. Could get shot full of holes and still be going. Still wouldn't want to pay the gas bill, they consume over 500 gallons of fuel per hour.

[johnson11b]

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

[paralleler]

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!"

[camzroon]

amazing.. have that same kind of engine at the museum of science in boston. great piece of enginering... mechanics hell? i got a real good close up look of that thing... so many moving parts. 4 rows of 7? geez. parts came and went fast, or so i would imagine lol

[irish89055]

paralleler... thanks, great stuff.. my father was pilot of a C -119 with two of these 4360's.. said the mechanics weren't too fond of them...

[intensetazer]

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."

[AceWalkerAstronaut]

Yes, and 1 more Sea Fury-"Furias" I think. I'm not sure, but I think those 3 racers-the F2G, Dreadnought and Furias-are the last 3 4360-powered aircraft flying in the world. The only flying C-119s that I know of are the 3350 versions and I think the KC-97s that were fighting fires have been grounded.

[oisiaa]

Great Video, much appreciated!

[elevpwron]

my father was mechanics of this type of aircraft in the 60´s in the argentine navy, he work with F4U, DC3, Beech C45, and Texan T6.

I am aircraft mechanic on Austral Lineas Aereas, a company of regional flights in argentina, with MD80´s.

We love the aircrafts (my father and me)...like You

[elevpwron]

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.
