The restoration to ground running of a Wright R-3350 Duplex-Cyclone radial engine.

Patrick Smart, co-founder of the HAE group rebuilds his R3350. A three year long quest to restore a Curtiss-Wright R-3350 turbo compound engine. A former engine to Lockheed Constellation 5T-TAF c/n 4618, it was one of two engines recovered for restoration.
Basic engine details: 18 cylinder radial in two banks of 9. Displacement of 3,348 in3 (54.86 litre) supercharged, with three turbine recovery units. Develops 3,250hp at 2,900rpm at sea level for 5 minutes, or 2,700hp at 2,600rpm at sea level at max continuous power.
Also appearing in the video are fellow HAE co-founders Peter Grieve and David Irwin, and HAE members Pete Irving and Paul Whitwood (and Jack the dog).

I love the R3350, but my heart still belongs to the P & W R2800, probably influenced by my family connection; my dad (RIP, Captain) was borne aloft many times by a brace of them in Korea, and they got him back safe every time. Oh, and they were attached to a hot rod plane called an A-26 Invader. Truthfully, I love any good radial engine, especially if they have 2 rows and at least 14 cylinders. The 18 cylinder engines have the sweetest sound, I think. Good show, gentlemen. May the Force be with you.

[@Beechnut985]

I like the sound of the power recovery turbines spooling down.

[@donframeli9855]

Thsts to short a run

[@GGigabiteM]

@@donframeli9855 No, it's not lmao. A PRT has nothing in common with a conventional turbo charger. The technology of a PRT is a throwback to the Victorian era of the late 1800s with steam turbines. Like a steam turbine, a PRT trades exhaust gas velocity for extra torque that is applied directly to the crank shaft via an oil fluid coupling. Since the PRT vane wheel is directly coupled to the crank, there is no "turbo lag", like there would be on a conventional turbo charger. It also doesn't greatly increase back pressure, since the blades are designed to absorb exhaust velocity, rather than being compressed. Really is a shame that nobody else thought of using PRTs on their engines, it makes piston engines a lot more efficient.

[@tgmccoy1556]

Love this I was a Copilot on a DC-7 Airtanker we flew two crew and I took the place of the FE. So I got good at management of four 3350's

[@jasonjones4941]

As an aircraft mechanic of 3.5 decades...I can tell you put your heart into this. Nice work!

[@bazwabat1]

Love the Star Wars style intro! That's a massive radial to bring back to life. Those cylinders are massive!

[@madmarkstoys]

You guys must feel like kings after all the hard work there's very few people that understand what you went through to get this R-3350 Duplex-Cyclone running again great video guys

[@MaistoHelix]

All, please bow to The Mother of all Radial Engines and never forget the moment you hear, smell and see it come to life for the first time. Great to see this baby being restored..

[@ATomRileyA]

Amazing work getting that beauty back and working, sounds wonderful too.

[@Deviation4360]

The intro created the perfect vibe for the gravity of rebuilding this monster. I haven't yet seen a rebuilt radial of this size come to life so spritely on the 1st go, it didn't even seem to want to settle below 2,000 rpm. Certainly no Chuk-ka-ta-chuck...cough smoke...weeze from this one.

[@mikearakelian6368]

The music made me smile,love attention to detail....you guys had way too much fun doing this...envious to be sure.i worked on my R20007M2s on the aircraft fun getting oily n dirty even on a hot ramp.secret was I never told my employer I was having fun really; best radial engine video I've seen yet!! Did good

[@HistoricAeroEngines]

Thank you Mike. Glad you enjoyed the fun we had. More R3350 videos later this year.

[@Robert-ff9wf]

I just love radials!! They sound awesome!!

[@chuckmorris7043]

those engines carried me for a couple thousand hours in Lockheed P2 Neptunes during the Vietnam war. I was radio operator and had a little window to look out and see the exhaust stacks for smoke and flames. Ha ha.

[@avalanche9026]

What accomplishment wow. Just fascinating bring back to live ?? Such history ?? Congratulations all team. Beautiful

[@paoloviti6156]

I think that you guys did a great job on this wonderful engine that is running so well with no smoke. Congratulations 👍👍👍

[@Nlangkirby135]

Well done! That R3350 purrs like a kitten now!

[@degatyphoon]

Excellent work, gentlemen!

[@rEdf196]

The once familiar roar of a R-3350 over Sproat Lake and The Port Alberni valley will soon only be a memory because the two long inactive Martin Mars flying boats are being reactivated for a final trip to Victoria BC Canada. and the other to Tucson Arizona USA. I hope Coulson saves a R-3350 for powerups at public events.

[@STuPification]

Thank you guys!

[@donframeli9855]

That is a valuable piece of machinery

[@Liberator74]

Brilliant - I never thought I would hear this beautiful noise! May the Connie force be with you! HK

[@jessejohnson159]

Beautifully done gentlemen! 😍😍😎😎

[@444mrjimmy]

what a sound, glorious

[@turbocompound]

Perfect work; the best „fuel to noise converter“…..🧐👍👍👍👍🏋️‍♀️…..! I take three batteries (36V) for starting my engine. Maybe that a direct fuel injected engine starts easier than engine with carburetor …🤷‍♀️

[@chiavenato1]

INjected engines don´t sound as good! I still remember my Harley Davidson showel, fantastic sound! My Road King sounds just good!

[@samsharp8539]

Finally. A cameraman who records the event from aft of the prop! So many record from in front of the engine so you can hear the prop noise better. Just what we want to hear. Not! Great job.

[@matthewwood4983]

I was involved with the 1649 Super Constellation engine O/H to test thru the re-assembly and overhaul of the 4 each QEC's for the project.... 4 years went into those QEC's...... Airworthiness condition O/H. For Lufthansa.....

[@matthewwood4983]

With spares......

[@markwitt7983]

That’s awesome!!!

[@haroldmclean3755]

Super High Kudos Boys 👍

[@dazhigh9208]

Wow after watching full vid, instant subscriber and sorry chaps gave you a round of applause. Huge smile on my face. Great stuff chaps Bravo

[@dazhigh9208]

Also excellent use of the theme. May the force be with you Always

[@HistoricAeroEngines]

Welcome aboard!

[@sainthelena1]

Love it!

[@martyb6903]

I might have a oh cylinder yellow tagged for this beast ive been hanging on to for years

[@jimmysparks315]

You guys need to do a night time video of engine running.... check out the flames...

[@catherinemorales5480]

Fun fact this engine was the engine of the B29

[@Scott.Silburn]

Fantastic!

[@rogerjohnson6218]

Nice....love the smell of 100 octane gas ..in the AM...:-)

[@chiavenato1]

Oh man, you should write your names! Great job!

[@mysticwine]

Talk about bad ass.

[@radioguy1620]

Amazing amount of work went into building and maintaining these beautys but boy huge amounts of toxic cleaners to clean and repair. My skin and body bears the scars but such is the price we pay for this work. use care if you do please

[@TonboIV]

It's kind of odd how the turbines keep spinning after the engine stops. How are they coupled to the crankshaft?

[@HistoricAeroEngines]

Power Recovery Turbines are geared to the crankshaft by fluid couplings, and recover about 20 percent of the exhaust energy at takeoff power (550hp) and 240 hp at cruise.

[@frostyab7579]

what's next, Pratt & Whitney R-4360 Wasp Major?

[@dukecraig2402]

My neighbors hate my motorcycle, they'd really be pissed off if I got one of those.

[@kkteutsch6416]

Or perhaps a Pratt Whitney R4360 instead !

[@dannywilliamson3340]

What's the gear ratio of the prop drive?

[@HistoricAeroEngines]

0.4375 : 1

[@haraldhannelius]

LOL the camera shakes in tune with the engine.

[@HistoricAeroEngines]

I think the ground is shaking with the camera on it! :-)

[@donframeli9855]

Sounds like the A3DS

[@aldenconsolver3428]

🙂

[@caninepro]

Greta Thunberg will be having a hissy fit! 😂

[@ThomasDoubting5]

Blunking heck , thats a big ole lump

[@gregoneill9194]

To much music

[@HistoricAeroEngines]

The action starts in the middle of the video. However, for context, there is a reason for the music and introduction. The engines were acquired from a special effects company which supported the Star Wars movies. The music and intro is a nod to that heritage. Hope you enjoyed the action when it starts.

[@KennethLWagner-yw9ko]

redo this no music , a little narration

[@jlalbee]

Super cool and all, but you spend enormous sums of time and money to watch it run for about 10 minutes and... then what?
