this is one of the best sounding radial engine videos out there, I love the sudden throttle at 2:11 and the flame shooting out the top exhaust at 1:32, I even love the turbo whine, even though I'm not usually a fan of that. great video.
@james west you are right AND Wrong ,, this engine is what's known as a Turbo Compounded engine it has a 2 speed 2 stage supercharger but it also has 3 power recovery turbines these are similar to turbos but they do not provide intake air they are geared to the crankshaft through fluid couplings and actually return exhaust power to the crankshaft ,,each one of the PRTs is connected to 6 cylinders and is capable of recovering 150HP so with 3 of them that's an extra 450HP to the crankshaft the PRTs are responsible for the turbo whine they are where the exhaust is mounted
I know right! I have never been able to hear the PR turbines spool in a video until this one. Gave me goosebumps when the throttle man got on it at 2:10
The backfire at 1.32 literally killed me! Really sweet rumble, I use this video as a background music while I'm browsing. :D No replacement for displacement!

I was in the U S Navy from 1967 -1973. After active duty, I was assigned to V-P 94 at NAS New Orleans.The squadron had P2V Neptunes assigned. These planes had two of these engines, plus small jet engines that ran on 115/145 also. I was an ADR 3rd class, and I worked on these engines. Nothing like a big stacked radial at idle.
My dad was an aviation machinist's mate in VP-47 at NAS North Island (San Diego), till 1957, and before that at Kaneohe Bay in the late 40s, working on the P5Ms and P5M2s. He was also occasionally flight engineer when they took those beasts up, and mentioned that it took eighteen hours to get from San Francisco to Honolulu at 125 mph.
That's good you were monitoring the head temperatures, I was getting concerned the engine was going to burn up with no cooling air. Even a barn fan or something would help out. But who am I to talk about running an engine without cooling air, though I did limit my FrankenBriggs 4 cylinder to a 40 second long run. I have also made a Tubo-compounded Briggs engine :) Sweet engine run!
Hi Joe, it`s not a stupid question: First, this engine formerly runs on AvGas with fuel grade 115/145, a highly leaded and purple coloured fuel. This fuel specification is so specially today, that it is only produced for events like air races with its high-performance piston engines. For our "show-runs", we will burn Shell V-Power 100 or equivalent fuel with antiknock additive, because, we don´t ask power. Before you can start the engine, draining off oil from the bottom intake-pipes and bottom cylinders will be required, preventing a hydraulic lock. You have to remove the spark plugs and three plugs from intake manifolds to do this. After this procedure, there is always an amount of residual oil in the cylinders and manifolds, that will burn out after starting the engine. That´s the reason for white smoking radials especially after cold starts. Regards Andre
yes 115/145 was used in the AD Skyraider around 700 gal would keep it aloft for around 8 hours , long enough to use up the 31 gal of oil it carried. 115/145 also made great Napalm with a little jell added..
Hi, thanks for comment. Yes, you are right. We are watching CHT-Temperature (Cylinder Head Temperature) very carefully. Temperature of top cylinders should never exceed more than 240 degrees, otherwise you have ignition without spark plugs. We are working for cooling engine with a cut off prop.
Normally a club-prop is used to generate some airflow through the engine and to provide some load on the engine at the same time. Especially with a multirow radial that is not unimportant because the main rod and cascade gears for the timing can otherwise get damaged. But not having the prop in this case provides a very rare clear engine sound example of this highly complex compound engine with supercharger and PRTs. Absolutely love it.
Those engines sound fantastic the really make it thunder gotta love Wright and pratt and whitney and rolls Royce as well as many other manufacturers of those days all the giant aircraft engines are thrilling
❤ That Bad A Idle!!!! Sounds like my nasty 406 SBC big A roller cam radical choppy Idle! And ⚠️ BTW the term "Holy Smokes" for some reason came to mind when it fired up! Wow them bottom cylinders and valve seals definitely allow in some oil into the combustion chambers! I know that they'd have to hand crank these radials over by the props to be sure they weren't hydro-locked by too much oil in one or more cylinders! But this shows everyone exactly why the ground crews would run them props over a few times lol!
Seeing how much oil came out the bottom exhaust when it started, I'm guessing oil that leaked by the bottom pistons as it sat since its last run; is there a procedure for clearing any oil before starting to be sure the lower cylinders don't hydrolock and break something? Such as a mechanism to hold the exhaust valves open while you spin it over a few times, etc..?
Hi David, in 32 years after first run, engine sounds good. Have a look to second video, there it sounds already better. Now, we are working on fine tuning. Andre
This is what is known as a "turbo-compound" engine. The turbos have NOTHING to to with airflow. Instead, they (3 of them) are linked to the crankshaft thru a fluid coupling, imparting additional power to the prop.
Lowell Goodyear if you want to see a modern interpretation of the turbo compound system, look at a Detroit Diesel DD15 engine in a semi truck. Same system.
Is there a clutch mechanism on the power recovery turbines that they only drive the crankshaft and not the other way around? In other words If you turn the prop by hand or starter does that turn the turbines?
Yes, between shaft of the PRT and gearwheel of the engine, there is a hydraulic clutch. If oil-pressure is rising up after starting the engine, PRT and gearwheel are connectet due to flowing oil. It is working like a torque converter in a car with automatic gearbox. So a smooth running without mechanical vibration is guaranteed.
+carp614 Yes, it is our hobby keeping this engine running and saving this wonderful piece of engineering from a scrap press. We have a lot of fun doing this. Next part is, mounting a prop for better cooling and flywheel mass
I know what the difference is between a supercharged and a turbocharged engine, but I'm still not quite sure what the difference was between a turbocharged engine on a normal fighter and the "power recovery" type of turbocharged engines on the Super Constellation and DC7. They called them "power recovery" turbines, but aren't all turbochargers, by definition, "power recovery" devices? What's special about the power recovery turbines on Super Constellations and DC7s that makes them different from other turbocharged engines?
+Todes Jaeger I've been looking into the radial engine last few days, from what i have found, the lack of load shouldn't be a problem. What is a problem tough is that an air cooled radial engine without a prop, doesn't get cooled enough, that's why i think they did not leave the engine on for a long time.
metamaster1492 Now, engine has a prop. Engine always ran smoothly without any vibrations. We didn't ask any power and crankshaft never exceeded higher rpm. All important parameters we watched carefully during our test runs. So, don't worry, engine is in best condition.
needed to be stripped and fully rebuilt before firing it up again. The amount of oil thrown from the exhaust suggests serious valve stem oil seal and piston ring wear..
Hi Paul, at the moment, that's our problem. We only can run the engine for a few minutes by watching the cylinder head temperature of the top cylinders. Don't worry, we don't overheat the engine. We are working on a cut-off prop for mass and cooling.
Thanks for your answer! I thought cylinder head temperature was an indicator for mixture richness...or was that EGT?!!.....I was just concerned about temperatures elsewhere, like cylinder barrel bases and crankcase.
With exhaust gas temperature, you can read the fuel to air ratio as well. For gasoline fuel, the stochiometric air-fuel mixture is about 15:1, that means, for every gram of fuel, 15 gram of air is required for full oxidation. If you run the engine on that mixture, it's heating up very fast. You can read this on high EGT with the result of fast increase of CHT. To prevent overheating, engines are running on fuel to air ratio less than 15:1, that means, mixture is more rich. Sorry, but explaining in English language, is not easy for me, I'm German, but I hope, you will understand it.
@@PistonAvatarGuy I think you'll find that animal agriculture represents 44% of anthropogenic methane emissions, the primary driver of climate change related to livestock, as methane is 34 times more potent than carbon dioxide over 100 years. Greenhouse gasses trap heat and are the leading cause of climate change.
I am actually looking for a Curtiss Wright R-3350 Engine. We currently use this engine to create wind at our testing laboratory. any leads would be appreciated I am located in Ontario Californa.
+o0DraastiK Yes, most likely oil coming out of the exhaust. And just about everywhere else as well!! On a cold startup, it was common to see an oil slick from the nacelle all the way back to the trailing edge of the flaps and dripping off the end. Typically, the R 3350s in the DC7s I flew would burn anywhere from 1 - 4 gallons of oil per hour. There were 2 old sayings about the 3350s......'if it ain't burning oil, it's because there's none left'....and when we'd pull up to the fuel station it was 'fill er up with oil and check the gas'. Lol. Originally, they used 115/145 avgas (purple fuel), but since that is no longer available, they now use 100 low-lead (blue fuel). With the reduced octane, the ignition timing was retarded a bit and high speed on the supercharger is no longer permitted.
Radial engines require a special fuel formulated just for radial engines. Same goes for inline engines, opposed engines, V engines and rotary engines. One must be very careful because it could cause extreme fun and out of control laughter.
Hi Mark, if you stop the engine, an amount of oil will be left in the crankcase. This hot oil is passing the pistons of bottom cylinders an will accumulate in the intake and exhaust stacks. Restarting the engine after longer shutdown, this oil is blowing out through the bottom exhaust pipe during first seconds. Standing behind the pipes during starting prcedure will make you look you like a crumble cake....!!
Star Light If engine is running with 1000 revs, it will need 1 liter per minute. If you start cold engine, it will need 4-5 liters until running smoothly.
2,200 hp at 2,800 rpm (takeoff power) This engine was only revving to about 1,500 rpm and no it's not harmful at these revs without a propeller load. These guys know what they are doing. read the info at the top. Do you have a car? Do you run it with no load, i.e., at idle? Do you even rev it at standstill occasionally?
Jamie Kugelmann Hi, not yet. We are working on one old prop with fibre blades. Problem ist, that the hub has a lot of corrosion, but we are confident, that it will work this summer. I have another complete prop with hollow steel blades, but this one, I will not cut back. It´s a pity. This complete prop, I will paint in original colours.
***** Awesome, good to see you are still working on it. Don't let the CHTs get over about 230C, it would be a shame to see it overheat. I would love an old radial engine to run, you're lucky you found this engine! Keep me updated on the progress and good luck :)
Jamie Kugelmann Yes, I keep you informed. The CHT we are watching carefully. We have two CHT-gauges on the front and rear top cylinders, but temperature maximum was 170 degrees centigrade during the first runs.
+turbocompound Seems like you could find a decent prop in the boneyards or scrapyards in the US Southwest. They were getting snagged up for art projects too. Museums may have some extras also.
+FiveCentsPlease I have two props, one complete from Neptune Aviation Services in Montana, which I will not cut and one from Netherland Air Force. This prop has cut off blades and at the moment, it will be painted in new colours. We will mount it to the engine this year.

Its the best cause we are hearing the engine without a prop.
I imagine that thing would start running hot pretty quickly without any airflow over the cylinders.
This is unique because there is no prop interference with the engine sound.
I know right! I have never been able to hear the PR turbines spool in a video until this one. Gave me goosebumps when the throttle man got on it at 2:10
