that old beast still alive after 75 years ,, i love seeing them running and hearing that sound i;'ve got a wright R-985 that i rebuilt 25 years ago , and i just love listening to it run
wildcoyote34, R- 985 sounds super. Watch video Matt younkin flying the beech-18. 985 puts out more than 450 hp. More like 550 h.p. He takes a lot of stupid chances doing inside loops 300 ft. Off the ground. To me that isn't good airmanship. He pops an engine at that altitude. He is a sure goner. I'M not a pilot. But, I do know I don't trust any engine at that height. 985's sounds like a giant Mccollough stroke.
Awesome. Love this stuff. Correct me if I'm wrong but I was always told that the test prop or "club" was not there just for cooling. It also acted as a harmonic balancer in addition to keeping the planetary gears in the nose case loaded. Glad to hear you have one now.
Yes, that's correct. You can overheat a radial engine with full prop, if it is only running on idle. Radials are cooled by ram-air during flight. The propeller cone doesn't only have aerodynamic function. During flight this cone will accelerate airflow and lead it through the gap between cone and engine cowling cooling cylinders and cylinder heads. The mass of airflow you can dose with the cowl flaps. The second reason, running engine with a club prop is load and flywheel effect. The frequencies of vibrations aren't "healthful" for several engine parts. Club props often have high pitch.
Wunderbare Aufnahme eines wunderbaren Motors. Vielen Dank. Es ist schön zu sehen, daß sich Technikbegeisterte um diesen beeindruckenden Motor kümmern und uns teilhaben lassen.
Assuming this engine is off of a P-2V Neptune given the decal on the forward oil/fuel tank. She sounds great! My dad flew P-2's in the 50's and 60's...
Bruce Miller Engine didn't run for a while and so it happened, that a small amount of oil accumulated in the bottom cylinders and manifolds. Before starting the engine, you are not able, draining this oil completely and after ignition, it burns out to this wonderful white clouds....😎😎
The Neptune P2V7 flow up to 1984 in the french "Marine Nationale" (Flottille 25F), last in FAAA base (Tahiti), one of them is maintained airworthy by a Australian association
Das stimt.. schön mal wieder das Maschinchen schnuren zu hören :-) Übrigens ist nächstes Jahr unser Treffen in Rees am Rhein und wenn Interesse besteht, würden wir uns freuen wenn der Sternmotor auch bei uns zum Einsatz käme. Eine Nachricht habe ich Euch ja zukommen lassen. lg
Adjust the oil pressure? Let me guess, you already have it maxed out, so you're gonna take off the housing and stretch the spring out....or put washers under it?
yah it looks hot from this distance i couldent see the temp when he showed the gauges hopfully thers enough wind blowin qwite the power plant though;RESPECT!!
These beasts were cold-blooded and could run for some minutes before ceasing up. They just had to carefully monitor the engine oil pressure, cylinder head temp etc.
So you're thinking the propeller cools the engine? LOL he didn't have it running long enough to overheat it. They rely on the motion of the air flying to cool the engines. They are air cooled engines but you got to be moving through the air. I don't think they're particularly cold-blooded. My dad put me in a AD Skyraider when I was 5 which has the bigger engine than this in it and started it up and it only took two or three revs to fire it and he kept it running just fine. The difference is; A. he was a farmer's son who'd been learning the art of throttle and manual chokes from the time he was a child and , B; he started one up almost every day For months at a time. I've seen people that rebuild corsair's and hellcats and they go to start them up and they struggle because they've never started one up before. It's like anything else you get better at it with practice. I'm going to say here to that I think this has a problem in that there running it without the propeller. A flywheel is a necessary component especially when it's cold. The big prop connected to these engines was the flywheel. It functioned as the flywheel. It'll be interesting to see if these engines have an actual flywheel but I'm sure they were designed with spinning weight in mind. So once it starts to pop and fire up the prop keeps at spinning if it coughs. The momentum of the prop keeps spinning the engine as the cylinder heads clear. I'm serious about that putting me in 1 at age 5 in starting one up. The 86 is what he was flying but the AD's were huge I'm had several different cockpit configurations. We were on base for some kind of inspection. I remember he was in his dress whites. And there was a sky Trader with a side by side as he walk me down the flight line. Want to go for a ride he says? Miramar Naval Air Station 1955. The patch on his flight jacket is the "Angeli Inferni" patch of the Hell's Angles squadron, VA 54.
Just For Fun Engine oil pools in the lower pistons when not in use. It begins to burn off as smoke when started. This engine probably sat for a long period.
is this beast turbocharged? it definitely sounds like it, but I didn't think turbocharging was developed this early. supercharging yes, but not turbocharging.
KinkyKinga1 Engine is not turbo charged. It has an engine driven supercharger with low-blower and high-blower setting. Impeller has a diameter of 13.5 in.. Additional parts are three power recovery turbines. Each turbine is supplied exhaus gases from six cylinders, three front and three rear. The turbines are geared to the crankshaft with help of fluid couplings. They utilize the velocity energy of exhaust gases, which is normally wasted. With help of each turbine, you can feed back nearly 150 hp to the crankshaft. That makes 450 hp additional horsepower.
The engine IS turbo charged. The 3 turbos not only drive induction compressors but also return power back to the drive shaft via the exhaust turbine drive shafts. These are not engine driven superchargers.
P38 Lightning was turbocharged. P47 Thunderbolt was turbocharged. B17's and B24's were turbocharged. British Typhoons and Tempests were turbocharged. All well before the turbocompound engines
If we start cold engine, it needs 5 liters until it will run smoothly. After pushing mixture lever to "rich"-position, switching off primer, it will need 1 liter per minute (1200 revs)
As a Briggs and stratton...dietroit diesel rebuilder....4 minutes in SHUT IT OFF... IT HAS NO NONE NOTTA COOLING...couldn't finish....I know cold oil....rear ones ....
It's hard to believe 18-year-old kids kept these engines running back in the war

I love how it starts coughing at 2.35, shakes the whole trailer!

Now it has one ...👍✌️...!
Count 9 blades before switching on the magnetos, to insure there was no hydraulic lock.

米国の方々が飛行機のエンジン単体を回して楽しむ様子に魅了されました。私も空冷ラジアルエンジンが大好きです。
Love it when they explode to life.
NO PROPELLER NO COOLING, THESE GUYS DO NOT DESERVE THE PRIVILEGE TO OWN THIS BEAST LET ALONE RUN IT AND WELL YOU NO WHAT I WOULD LIKE TO SAY.
Please, firstly, master the use of the CAPS LOCK key before commenting.
Godfrey Poon well Godfrey you reed it just fine
Suddenly this trailer became a 2500hp muscle trailer.
Sounds like a friggin train engine with the turbis🔥💯👌
Assuming this engine is off of a P-2V Neptune given the decal on the forward oil/fuel tank. She sounds great! My dad flew P-2's in the 50's and 60's...
flewnvy Yes, engine is a Curtiss Wright R-3350 32WA from Lockheed P2-V7.
Since it has total loss oil injection what oil does it burn?
Bruce Miller

Verdammte Luftverschmutzung!

Good to see another video of it!!
I suspect they do not have a primer pump to start it up fast. The primed gas shoots directly into the super charge impeller before govener is engaged.
Jesus, they're all so serious. Have some fun with it guys. It's not brain surgery.
Engine builders were smarter back then
1:20 looks like the morning dew is drying off.
Got a current video?
Das stimt.. schön mal wieder das Maschinchen schnuren zu hören :-)
Übrigens ist nächstes Jahr unser Treffen in Rees am Rhein und wenn Interesse besteht, würden wir uns freuen wenn der Sternmotor auch bei uns zum Einsatz käme.
Eine Nachricht habe ich Euch ja zukommen lassen. lg
Yeah... what he said.
god that sounds good when they throttle it up
MUSIC TO MY EARS!
Where is the prop?
That thing needs a short bladed prop. Sound excellent....needs cooling air....and some " load"..
what other planes used this power plant,sir?
No way I'd run that for 5 minutes like that, without the propeller to keep cool
You could run it for 20 mins and not even get close to high CHTs.
Adjust the oil pressure? Let me guess, you already have it maxed out, so you're gonna take off the housing and stretch the spring out....or put washers under it?
Who could dislike this video?
Luddites, and people who wanted to see this in a Skyraider.
yah it looks hot from this distance i couldent see the temp when he showed the gauges hopfully thers enough wind blowin qwite the power plant though;RESPECT!!
That supposed to be a air cooled engine why .No prop to cool it with
How do you keep the Engine cool with no propeller ?
Jeffrey Kumjian Don't worry, now it has one......
Not running it for extended periods of time, I'm guessing.
These beasts were cold-blooded and could run for some minutes before ceasing up. They just had to carefully
monitor the engine oil pressure, cylinder head temp etc.

Jeffrey Kumjian YOU DONT. IT WILL OVERHEAT WITHOUT A PROP.
Got a few bad oil rings.....plus it is overheating...
No, it won't overheat, I'm pretty sure they were gauging the cylinder head temp and shut it down before it got too hot..
Sure wish you guys had a club prop. Or at the very least, a high-flow ducted fan. A 33 1/2 is hard enough to keep cool. A PRT is even worse.
Maybe have props on it cool off ??
Why so much smoke?
Just For Fun Engine oil pools in the lower pistons when not in use. It begins to burn off as smoke when started. This engine probably sat for a long period.
Because they do. The bottom (upside down) cylinders are prone to accumulate oil when the oil seeps past the rings.
is this beast turbocharged? it definitely sounds like it, but I didn't think turbocharging was developed this early. supercharging yes, but not turbocharging.

They are called "power recovery" turbines.
P38 Lightning was turbocharged. P47 Thunderbolt was turbocharged. B17's and B24's were turbocharged. British Typhoons and Tempests were turbocharged. All well before the turbocompound engines
Typhoons and Tempests were not turbocharged. The British fielded no UK-made turbocharged aircraft during the Second World War, unlike the US.
How much fuel does it consume in one session?
If we start cold engine, it needs 5 liters until it will run smoothly. After pushing mixture lever to "rich"-position, switching off primer, it will need 1 liter per minute (1200 revs)
Thanks! High-octane leaded gasoline?
I see two levers at the dash, one of them is obviously the throttle, the other one is mixture control?
No, we use MoGas, Shell V-Power-100, because we don't ask power. Yes, the two levers are mixture and throttle.
turbocompound 5 liters of fuel that’s not that much ...
How does this work without a "club?"
Hi Bill, we will mount a prop next week on Easter Monday. A friend of mine will bring it from Netherland.
+turbocompound looks great but 'HOT'
Wenn das Green Peace sieht... :D
Klimmek Der läuft doch auf Bioethanol und Rizinusöl....😎😎😎😎😷😷
Should have at least a small prop on it for cooling
Is that oil coming from the exhaust?
49827ij Yes, the first minutes, engine is burning a small amount of oil from bottom cylinders and manifolds.
Waist of an iconic engine the way they showcase it wheeled around on a trailer
@soaringtractor 😂
wow
As a Briggs and stratton...dietroit diesel rebuilder....4 minutes in SHUT IT OFF... IT HAS NO NONE NOTTA COOLING...couldn't finish....I know cold oil....rear ones ....
Sau dumm luftgekühlte zylinder ohne Propeller laufen lassen
Der meiste Rauch kommt deshalb wohl auch von den Kopfdichtungen
비행기 앤지 뜯어서 시동한번 걸어보고....
뭘 어쩌겠다는건지??
