Somewhere in an alternate universe a P&W engineer had a batshit idea and develop a 2-stroke version of the Wasp Major, which would’ve been a huge rival to Rolls Royce’s Crecy. Lighter, more horsepower, and WAYYYYYYYYYY louder. Great video! Used to confuse this with the similarly notorious Wright R-3350 Cyclone engine.
Imagine the guys who worked day after day to maximize airflow to barely get it to not overheat, and then their boss says he now wants a 2 stroke variant.
@@albero319 Not just that, but a better way to implement sleeve/reed valves for exhaust scavenging on top of the already complicated cooling system. Maybe throw in a reverse-engineered BMW-801’s active cooling and direct fuel injection for good measure. Just to squeeze out every ounce of performance.
The SuperGuppy pictured in your video, although based on the K97, had turboprops instead of the R4360's. The shape of the engine nacelles is quite different.
As an aviation enthusiast I knew of this engine and have been incredulous at it's complexity. What an engineering masterpiece and of production engineering. America could certainly produce some fantastic kit. Over here in the UK we had an engine manufacturer who wouldn't make anything unless it was fiendishly complicated. Napier was their name and the Nomad was probably the pinnacle of their love of such engines.
I can’t remember the documentary I saw this on but for this engine to test the reliability of the Pratt & Whitney R-2800 Double Wasp engine to make sure it would be great in World War II fighters they tested it by running it at max power for 24 hours and it didn’t break and the test bed made 3400 hp but was reduced to 2800 to help keep the engines lifespan so 24 hours at 3400 RPM that’s one hell of a dino pull
I love watching and listening to these big radials; they seem so absurdly complex they can't possibly work, but they did, and well!! Thank you for featuring these separately!
Good to see... My ex-father-in-law (now deceased) was a young engineer on a last hurrah effort to produce a radial engine competitor to the new jet engines. P-W made 56 cylinder prototype engines by joining 2 R4360 units. 3 units were built. All suffered from excessive timing variation between the first and last rows of cylinders. As much as 7 degrees of slop in timing from #1 to #56. The last prototype ran on the test dyno for 3 hours before self destruction. The program was terminated at that point.
Wonderful video, thank you for sharing it. BTW, the "Super Guppy" does not the R-4360, but turboprop engines. If you listen carefully towards the end of your video you can hear the turboprop on the "Guppy" at the 9:00 mark in the video. That's clearly the Allison 501-D22C.
It’s amazing to see human design at the point where a technology has neared its potential and a new revolutionary technology displaces it. These radials were truly cutting edge
Have to piont out that whils the Aero Spacelines Pregnant Guppy used Pratt & Whitney Wasp Major engines, the aircaft featured in your video is the Super Guppy which uses Allison 501-D22C turboprops.
The complexity and engineering of that 28 cylinder radial engine is just awesome 👍🏿and with all those cylinders that's a smooth running engine for sure
This was designed by slide rules and mechanical calculators, not computers. That is amazing. My father worked on the C-W Turbo Compound engines 1953-1963 and those were crazy complicated.
The Super Guppy you're showing had turbine engines I believe. I've seen the HFB-1 at both Long Beach and McMinnville... that's where you get to see the engine cut-away (with the red paint). The huge Lycoming engine is at Udvar-Hazy... it is magnificent.
Nice video, you spoke about problems in the beginnning......well the Boeing Stratocruiser with four P&W Wasp Majors was nicknamed the best 3-engined airliner. But think of the fact that all calculations were made with a slide ruler. Thanks. PS, you probably know them all but and covered them..... for a future video you could have a look at: the Aspin engine, the Junckers Jumo 205 and 223, did you cover the Napier Deltic?, the Bristol 5 cilinder swash plate engine, the Massive Yet Tiny engine, free piston engine, Saturn rocket F1 engine,
I remember my schooldays with log books and slide rules. I think I must have been in the last generation to use them. Hated the log books but loved my slide rule though I always had the niggle that absolute accuracy was sacrificed for speed. I treasured my slide rule loving and protecting it for many years but never used it again. After school I never saw either in use again and as I started work early electronic calculators become available, my first one cost £52.00 - more than a month's pay. It didn't even have a % key or a memory, just the basic plus minus multiply and divide. I remember my 15 floor office buildings heating engineers asked me to calculate the water volume of the heating system for them to correctly dose the corrosion inhibitor. That was a major task but made practicable and enjoyable by my first calculator. How times change and how quickly too. Sorry to ramble on, I have insomnia and my brain is racing.
For anyone who is in the midwest/ plains states. Go visit Pinoneer Village in Minden Nebraska. They have one on display, and yes it is huge. Funny thing was, as I would walk through the exhibits, I would teach out and touch them. For some reason, I wanted to touch history. They have others as well. Viso, another great video brother, please keep up the great work and weird finds that you find. God bless brother.
An old-timer Pratt engineer I spoke with - his job was to test every engine that left their factory - was thrilled with the switch to jet engines. Apparently the piston engines were absolutely FILTHY to work with. Not to mention what happens to your day if you accidentally foul the spark plugs & need to change them all.
I can't imagine changing all of the spark plugs on a B36, the 6 radials alone have something like 336 spark plugs, plus the ignition plugs in the 4 J-74 engines and the APU
@@TheReadBaron91 I installed an engine on a SR20 and an SR22. The tuned induction engines are a huge leap forward compared to the older ones. LOP operation is possible without GAMI's. I didn't enjoy flying them as much as I had hoped I would. They feel heavy and sluggish on the stick.
Been wanting to see somebody respect this engine since I heard a running b29 as a kid. As somebody with a big block drag car, nothing can beat the sound of these.
The B29 didn't have this engine, it used the Wright R3350. The B50, which was kind of a B29, had these engine's, developed too late to be used in WW2 the B50 did see use in the Korean War.
When building a plane or a car, you learn very quickly which engines are performers and which ones aren’t. Why you you choose an inferior engine is beyond me, but too each there own. Wright was notorious for having severe casting defects in their cases. Casting defects that could lead to potential grenading. I’m guessing that’s why they dumped the Wright motor. That would be akin to choosing a vw1600 over a rotax engine to power a small aircraft.
I got to go to the air museum in Oregon that currently houses the spruce goose. This was in ‘01 so it wasn’t there yet but the place is in a blimp hanger and was at one time the largest freestanding wooden structure in the country.
Your video contains a significant error. The NASA Super Guppy that you have included in your video is not a Wasp driven aircraft, instead it uses four Allison Allison 501 D22C turboprops. The short sequence where the aircraft is shown taxiing clearly displays turoprop engine noise. The NASA Super Guppy (Reg. N941NA) was originally built for Airbus to transport parts for Airbus aircraft and did so from 1983 until 1997 with the registration F-GEAI. It is the last remaining airworthy Super Guppy.
The later variants had a hybrid turbocharger designed by GE. IIRC, an exhaust turbine powered a shaft that went to a gearbox that then put the power directly back onto the crankshaft.
Rolls-Royce realised that piston engines were getting too complicated. Their supercharger (from Merlin and Griffon) had become supremely efficient so they went to turbo jets and turbo props and avoided the step yo huge multi-row radials.
Everyone did, engine's like this were only made because aircraft designers called for powerplants for massive new aircraft designs before jet engine's were capable of doing the job. What was everyone supposed to do, sit on their hands for 10 years without designing new aircraft waiting on jet engine's to be ready?
Radials were never Rolls Royce's thing. The World War 2 European theatre was mainly fought over land (with the exception of the English channel) with both sides employing watercooled V engines, with advanced features such as 4 valves per cylinder and sodium cooled valves. Aircooled radials were used more in the Pacific theatre, by both Americans and Japanese. The lack of a liquid cooling system made them more robust (especially under fire) which was vital when fighting over open water. There was one British manufacturer known for its radial engines: Bristol, which produced the 18 cylinder centaurus as well as some 14 cylinder engines, and specialised in sleeve valves. Pratt & Whitney's 28 cylinder Wasp Major was a very successful engine (nowhere near as succesful as their 18 cylinder double wasp) and is as far as I know the only successful radial aero engine with more than 2 rows.
Hughes aircraft designs always seemed to be underpowered graceful catwalk model types inspiring everyone, in stark contrast to what actually went into the war zones like the Grumman-Vought-Republic-Curtiss-etc designs. A T56 powered (see your footage of the Boeing Super-Guppy as exampled engines) Hughes H4 would easily have flown, they just weren't available yet for this revolutionary design. I've seen that 3D model of the R-4360 before and wondered why the modeler put the way under sized prop on the front, it's truly the best impression of this engines power to see a museum piece with its actual prop hanging up front. The H4's engine nacelles look like mere nubs for the huge props Howard hung on the front of those units, yet all that HP still wasn't enough.
When was this designed? What? 80 YEARS AGO?! The word "computer" probably didn't even exist back then! The engineering prowess of those times is just mind blowing...
To be clear the engines are also ALL Oil cooled as the function of oil is not only lubrication which in itself prevents heat, but also as a heat exchanger
Not all versions were rated at 4,300 HP, most were only tuned to 3,500 HP. Only the turbo/fluid coupled version was rated at 4,300 HP, and they were only used in a few applications.
Those Goodyear F2g Corsairs were bought up by a guy named Cook Cleland and used to win the last Thompson trophy races in in Cleveland Ohio. I think it was 1949 when a highly modified P-51 Mustang called the Beguine with a very inexperienced pilot crashed into a house and killed a mother and her two children. That was the last year A Thompson trophy race was held in Cleveland.
@VisioRacer, hi , I am fellow engine nerd and I wold love for you to make a video about the Sulzer 12LDA28 engine. It was used in locomotives in the '60s and some are still in use in some Eastern European countries.
There are even a few remaining Class 47 locos trundling around Britain with their original 12LDA28C engines still working (more or less...). I've traveled many miles behind locos powered by LDA28s, including the 6- and 8-cylinder variants, and I have happy memories of the sound of hard-working Sulzers. Are there still Sulzer-powered locos in Slovakia?
@@icenijohn2 I don't know about Slovakia, because I am originally from Romania. On the Romanian railways there are still some locos that still use the Sulzer or a Romanian license made engine. There are two types of Romanian produces locos powered by this engine: the LDE type: diesel-electric and the LDH type:: diesel-hydraulic. I also have always loved the sound of this engine, no matter if was idling or working hard.
Why wouldn't there be? The engine's designed today are far more advanced than these, don't think that just because these engine's were so big they were anywhere near as advanced as a modern 4 cylinder car engine, you're confusing size with technology.
I'd pay a good chunk of money just to stand near the runway of a plane carrying 6 of these monster engines while full throttle and taking off. I've been to a couple air shows locally, and I much prefer the sound of a radial engine to a V engine on an aircraft, without disrespect to the P-51.
Without CAD THESE engineers created this incredible Combustion Engine today with only Pocket slide rules. They would struggle to recreate from scratch this engine.
Would have been an amazing fly-over sound with the 8 - 28 cylinder engines R4360''s of the 'Spruce Goose' humming over head, much as we enjoy the sound of a Messerschmidt Bf-109 with Daimler-Benz DB-605 inverted v-12 or a Merlin V-12 Rolls-Royce engine fighter aircraft of world war two!

It took piston engine technology about as far as it could go. Fortunately, gas turbines took over.
piston engines are still unmatched today for its fuel economy right??
For low speed flights, perhaps. The more power you need, the more impractical piston engines get. Jet engines are much easier to scale up.
Would have been an amazing fly-over sound with the 8 - 28 cylinder engines R4360''s of the 'Spruce Goose' humming over head, much as we enjoy the sound of a Messerschmidt Bf-109 with Daimler-Benz DB-605 inverted v-12 or a Merlin V-12 Rolls-Royce engine fighter aircraft of world war two!
Good shit. 👍👍👍
