AFTER MORE THAN 80 YEARS SINCE IT LAST RAN ANDREWK (ASSISTED BY GREGC); STARTED HIS 160 H.P. GNOME ROTARY AEROPLANE ENGINE. THE ENGINE WILL POWER THE NIEUPORT 28 NOW BEING RESTORED BY ANDREW. ALL WERE WONDERING IF IT WOULD BE DIFFICULT TO START ... IT WAS NOT ... IT WAS DIFFICULT TO STOP IT AFTER EACH OF THE SIX START UPS. ELECTRICAL PROBLEMS AROSE AND THE ENGINE WOULDN'T STOP UNTIL THE FUEL WAS CUT OFF. A SWITCH IS SUSPECT. TROUBLESHOOTING CONTINUES. FOR FURTHER EXPLANATION SEE -

1st: It was advantageous for cooling when the cylinders spinned around, since air-plane engines in World War I were air-cooled. 2nd: Radial engines in general, including the rotary ones, were significantly superior to the usual V-motors, which is why constructors were willing to use them despite their detriments. 3rd: Yes, rotary motors had the problem of being large and having a gyroscopic effect. This is why they were abandoned soon after the V-motors catched up with their performance.

I know its a little larger than the early 50hp version, but just imagine that thing spinning away 6 feet behind your head, as you're 400 feet in the air on a wood frame covered by fabric, held together by piano wire. With no ground communication!

They didn't "leak" oil, per se. They utilized a "total loss" oiling system, as did many early engines. And Castor oil was the lubrication of choice in those days for many engines.

Great job guys. It takes real men to withstand all this commotion, particularly since it'll blow yer hair off. All kidding aside, I'm thrilled to see folks preserve such important aviation history. Thanks for a great show...........p

The 9n Gnome Monosopape was pretty much the limit of Rotary engine development, you needed exponentially bigger engines to get small increases in power beyond that. They went more with Radial and Inlines after WWI. The engine was in a surviving original N.28 as far as I know, and the plane hadn't been flown since the '20s. Was basically like finding a classic car in a barn- everything was intact and in working order, just needed TLC and knowhow to bring it back to life.

Thank You, I would watch this engine and you guys running it a hundred times and still could enjoy more. It reminds me of my friend Ted (rest his soul) and I in better days. Thankx again, Markus Carwash Perry

That was pleasant. I felt like I was hangn' out with'em.

@dnebdal 14 лет назад

It has a few benefits. The engine gets very good cooling even when standing still on the ground, and they run quite smooth since the entire engine works as a flywheel. Some comparable non-rotaries added flywheels, but that's a lot of extra weight. It has definite drawbacks, ofc. It's hard to scale them much further, and they were indeed quite gyroscopic. The Sopwith Camel was notoriously hard to fly for that reason. :)

Two nice guys doing a superb job and enjoying it. Well done boys.Hope you got the glitches sorted out.

It looks like a radial engine, but is different. A rotary engine has the cylinders rotating around the crankshaft, which stands still. The propellor is simply bolted on the engine. A radial engine has fixed cylinders and a rotating crankshaft. Gnome rotary engines were widely used in World War I on fighter planes, built by Gnome Rhone factory and licencees on both sides of the conflict.

@antadefector 12 лет назад

I think that these rotating engines were dumped because they had extreme gyroscopic forces on them, especially for later, more powerful motor like this one. I am no expert on the thing, but there should be a shorting switch for killing the engine. Opening one end will not help since it will surely spark over in switch (for most of magneto ignition). Best Regards, Goran

Love your droll sense of humour ... "Holy Cow!!" And the assistant gets debonneted in the slipstream!

@homebuiltindoorplane 11 лет назад

that was fantastic, thank you

@neomuttley i am sooooo jealous that you life so close up there. i had the Privilege to talk to Cole Palen on the phone early 90. as i was doing research for a 1/3 scale Fokker DVIII Avery nice extraordinary man :)

@marksf8 11 лет назад

have a look here, and you can see the wiring at the start of the vid.. 1909 Gnome Omega Rotary Aircraft Engine

@GGigabiteM 15 лет назад

The Siemens Halske SH.III and the Bentley BR2 were the height of rotary engines. The Halske had a real throttle and the BR2 was 250+ HP, which the monsoupape couldn't hold a candle to. If someone attempted to make a rotary today, it would probably be lighter and produce far more horsepower than they did 90 years ago. I remember seeing somewhere that someone was making a new Bentley BR2.

@firesyde424 12 лет назад

So, when he is rotating the engine with the fuel on, before it starts, what is that for? Is he making sure all the cylinders have fuel/oil?

@Hawaiifive01 13 лет назад

@946HZJ: Its BOTH a rotary AND a radial

@tpanayi66 11 лет назад

@ 2:50 still can't keep his hat on even flipped back. Love it! This cracks me up.

@neomuttley 14 лет назад

Music to my ears :-). We've a wonderful living museum by me in NY (@Rhinebeck). They stopped running rotaries a few years back, much to my lament. I hope they correct that soon. They fly many planes there.

@FPVandotherprojects 11 лет назад

Thanks for the historic sights and sounds.

@RodolfoMaschio 11 лет назад

I think that type of engine is a good idea and can work well when connected to an electrical generator and the system is securely fastened to the ground. That "radial engine reverse" mounted on an aircraft will create dangerous "gyroscopic moments" that abruptly alter the stability of the 'plane plunging the aircraft and its occupants.

@hellraised187 13 лет назад

@eplefox1 I think they have a magneto ignition system which is attached to the crankcase

@samipso 15 лет назад

They made a new stronger engine every couple months during world war 1 when planes were introduced. That's gotta be the reason it's still in working order.

@zodwik 11 лет назад

ya knowwww....you could put an eye out with that thing!

@946HZJ 14 лет назад

@dasadler123 its a rotary not a radial

@ignasanchezl 12 лет назад

is like an out runner motor

@adoreslaurel 11 лет назад

Maybe they have something like an electric motor commutator stationary between airframe and engine and a wire from each plug to it and a carbon brush contacting it.

@watchdoggibson 15 лет назад

Hey guy's this was realy great , I think your grounding system was posibly reversed on the switches . Try switching the positive and grounding wires thats on the switches. Other than that , It was wounderful.

@bldeagle 14 лет назад

Got it running correctly, see "1918 Gnome rotary engine running"

@wollin20 11 лет назад

Almost like archeological experimentation!

@eplefox1 14 лет назад

How does the ignition system works? i gues there is no wiers to the cylinders.

@sprintfan1 13 лет назад

What was the shutdown problem? It says above a switch was suspect.. Or was it wired wrong?To kill a magneto fired motor, you ground the magneto out. Easy to have reversed, and also hard on the switch.

@ColonelKlank 13 лет назад

That's Greg Cone!

@dasadler123 14 лет назад

If I'm correct this isn't a replica? She won't run because she is an old old old cranky radial. Once you get her running she will be bulletproof though!!!! =)
