@freakyboie19699 The point is that these engines were remarkable pieces of engineering for their time. Most of these running displays are using engines that no longer pass inspection for airworthy projects, but they are assembled and ran by hobbyists as a labor of love. For the aviation gearheads, it's neat to be able to see and hear these engines up close instead of far behind crowd lines at airshows. They are ran by people who appreciate them instead of destroyed in motor racing sports.
That must be out of a four engine Shackleton with the counter rotating props. They used to fly low over our house when we lived in Newquay Cornwall in the '60s. Beautiful noise. They sounded a helluva lot better than in the vid.
Just listening to that V12 at full throttle sends a shiver down my spine. Better than the best music. I guess it has direct fuel injection, 4 valves per cylinder and 36 spark plugs.
Two later mark of spitfire were fitted with this engine,right at the end,or just after WW2.If your looking for the ultimate in Rolls Royce piston engines look no further than the Eagle, it produced over 3,000 HP and was fitted to planes such as the Wyvern prototype.Only 15 were ever made.The Eagle engine really epitomises piston engine development-only to be over shadowed by the new breed of turbo jet engines-like the Rolls Royce Derwent.
Most dual or quad engine planes that use counter rotating propellers have them going outwards due to strange effects on the flight characteristics of the plane when rotating inwards. The P38 originally had inward rotating propellers, but it caused undesired problems and they changed. But you are correct that you can have them go both ways.
@zeppelin67637 The propellers are geared off of the crankshaft using a reduction gear (common for many aircraft engines.) The contra-rotating prop on the Griffon used an idler gear to rotate one propeller shaft (fitted inside the larger one) in the opposite direction. It had two benefits, one is that contra-propellers moved air more efficiently and the other is that they canceled the dangerous torque effect of a big prop on the airframe, which can cause tricky handling for pilots.
@T3hbassmasta But the Griffon and Merlin V12s are liquid-cooled. There's a coolant radiator behind the prop on this trailer. Even most air-cooled radials will use an oil-cooler for running displays.
@aaronzack14 For the Griffon Mk. 58 is this video, the fuel demand at maximum power setting is 189 gallons per hour, or 3 gallons per minute. At typical cruise settings, this will be lower (60 gallons per hour for the smaller Merlin at cruise.) A gentle idle with some throttle will consume less, of course, and this engine with cut-down props will never be run at maximum settings since it can be damaged.
In the Australian outback i've seen such engine's in sheds with a generator connected to it to power roadhouses and it's buildings around it. Maybe it's also possible to put it on a truck.. or those giant mine excavators.. or in coober pedy they have some kind of giant vacuum suckers on trucks to filter the opal from the sand, driven by truck engines. There are thousands of purposes for such engines but in normal city life somebody never thinks about those ;)
@WilliamGruff Almost all private aviation engines are air cooled. You can run them at idle (or close to) for a long time because the propellers cool the engine. But If you were to leave it at full power you would need to be up in the air and moving because the propellers do not give enough air to cool the engine.
@WilliamGruff The u-shaped object below and behind the prop is the coolant tank for oil and coolant. These display engines are not run at high throttle settings or for very long usually, so they don't get very hot.
Two props rotating in opposite directions on the same shaft is contra-rotating, not counter rotating. Counter rotating propellers would be the P38 where both engines turn outwards from the cockpit.
@kaysandesses Pilots of the P51 would initially use 30 gallons of fuel from the external tanks in early flight, then switch back to main tanks in order to balance the aircraft. So presumably, one refers to 70 gallons per hour.
Contra rotating propellers. Counter is on a twin engine plane with each prop spinning opposite to the other. It means there will be no critical engine because the down going blade will be closest to the fuselage.
@CrazyForCooCooPuffs These engines don't run anywhere near 6000 RPM. Typically they run in the neighborhood of 3000 RPM (plus or minus depending on the engine). There is already a transmission between the engine crankshaft and the propeller--it's called the reduction gear so the propeller turns less RPM than the engine. This ground display won't be operated a max RPM to avoid damage since the prop blades have been cut shorter.
nah that's the odd firing order of the Griffon... the "Griffon Growl". Apparently the engineers at the time thought that the pulsing of the firing order of the Merlin put undue stress on the crankshaft and so made it different for the Griffon. Listen to a Merlin Spitfire next to a Griffon & you'll hear the difference.
@aaronzack14 You are totally correct. It is quite logical in your statement. If a Spitfire is cruising at 280mph, using, lets say, 7 gallons an hour, its mpg would be much better than most modern cars at 40mpg. So, as you say, 70 gallons per hour is a more likely figure, if not more. Similar engines were used in tanks and the fuel consumption was so huge, it was more appropriate to measure it in, not in mpg but gpm. Some tanks used 2 gallons for every mile.
@hobbyguy The Griffon has a different V12 firing order compared with the Merlin, which gives it the characteristic raspy growl. Plus they aren't really running at high RPM because the prop blades are cut shorter, which could over-speed the engine.
@FiveCentsPlease You are right. These engines don't get anywhere near 6000rpm. If it did, it would have no pistons left! Even at 3000rpm, is quite high, when you consider the piston mass, length of stroke etc.
Probally have the pitch of the props set to blow on each other so no thrust is generated. I like the sound when it idles, and the lean pops when he slams the thorttal shut... :) :)
@FiveCentsPlease I think he meant 1 gear as in 1st, 2nd, 3rd like a car. In that case, yes, there is one fixed gear ratio, the angle of the propeller blades, or their "pitch" is instead adjusted. This has the same effect as changing gears in a car.
That would be a cool funeral story too! Who ever thumbs downed my comment is ignorant!! Clearly the exhaust is getting blown into their faces by the props.Just being observant was all.I find this pretty cool actually.
Were this engines used in anything other than late model Spitfires...? I wonder (oh yeah, it's "Griffon", not "Griffin") What a beauty... Too bad a video can't possibly capture the true noise of this engine... Thanks for posting! :-)
True, the radials are air cooled. So the Focke-Wulf fw190, Mitsubishi Zero, P-47 Thunderbolt and Lavochkin La-7 all were aircooled. Anyway liquid cooling is hardly a post WW2 invention. Porsche continued with their aircooled flat 6 all the way to 1995.
Airplane engines can be this big as well by the way, i've worked on an airport for few months and the propeller driven airplanes have Huge piston engines, even bigger than this one. Makes an insane noise as well by the way, 100 meters around it you cant say a word.
@turismofreak The prop blades are cut down shorter and they really aren't putting the rpms high enough to overcome the weight of the engine and trailer. Most of these displays with the cut down props can't rev to high rpm because the lighter propeller has less mass and the engine would over-speed and come to pieces.
@CrazyForCooCooPuffs The counter-rotating props are a little more complex than just one gear, and it wasn't perfected until after the war. Typically it is just one gear, sometimes with accessory gears to drive other things like magnetos or camshafts (sometimes those are driven on the back side of the engine instead.)
Really? Never would've guessed it. I'm guessing though that they phased the idea out, jet engines coming in and all. The Tu-95 has an engine config like that though, so the idea was not abandoned. :)
Incorrect. Dual propellers like that are called contra-rotating propellers. The purpose in that is to cancel out the torque of having a large mass rotating one way which changes the flight characteristics of an airplane. Despite the opposite rotation of the propellers, they are both pulling air in from the front of the engine and blowing it towards the rear; as you can see from the guy in the back getting blown around.
@1100HondaCB Only 24 spark plugs, 2 per cylinder (inlet and exhaust). They also have a twin speed supercharger, water meths injection and variable valve timing if I remember rightly.
@dreadnaught6399 The counter-rotating propeller setup moves air more efficiently than a single prop. It wasn't perfected until after the war. The other benefit is that the weight of the propellers turning in opposite directions cancel each other out and eliminate the torque effects of the heavy prop on the aircraft, which can make handling difficult. See: "torque roll" and the dangers of applying too much power during aborted landings.
@nvtuning No, both props are providing equal forward thrust. Otherwise it wouldn't be very helpful for flying would it? Counter-props move air more efficiently and eliminate the tricky torque effects of the big prop. Most of these running displays use props that are cut down from normal size, so they won't produce full thrust. Without the weight of a normal prop, these engines are not run at high rpm because they could over-speed and start breaking parts. The trailers are tied down well also.
@easycheezy85 Fairey Firefly, late-war Supermarine Spitfires and Seafire, and most noteably the Avro-Shackleton maritime patrol plane that was used until a couple of decades ago. The contra-rotating propellers were not really perfected until after the end of the war.
@vinnie01 Contra-props are more efficient at moving air and they eliminate the dangerous torque-effect from the big prop on the airframe, which can make the handling tricky. Too much throttle in slow flight cause the aircraft to rotate against the prop torque. The contra design was not really perfected and used until after the war.
Some people just like to flirt with danger, hope you regularly inspect your mounting points there mate...also i see your trailer fender flappin; ... that would hurt some on the side of the head ... play safe... i love the motor,
@mitchonii That's perfectly fine. Don't worry about it. I know how frustrating it can be. Nuts, bolts, wires and tools are my life. I think it came from watching my dad strip engines in the kitchen :0) And you too have a nice day too.
@FiveCentsPlease Indeed, but those both started their lives as military aviation engines, now used in privately owned aircraft. I should have been more specific in my statement. I meant all civilly built and owned aircraft, such as beechcraft and Cessna
1. It is a Rolls Royce GRIFFON not griffin engine. 2. Contra-rotating propellers both provide forward thrust for the engine & airframe/. They do not cancel each other out. 3. It sounds rough at higher revs from either fuel starvation faulty magnetos or too low boost pressure. 4. Frequent and rapid changes in revs as in the video will stress the engine unduly- it was designed to operate at constant rev settings NOT to be revved like a modern car or bike engine. Is it still working?
That particular time always seems to be a haze to me as far as what tech had the voice of the day. OOH people were happy that they could fly, cheaply... Or cheaper at least, even in the radial powered Boeings and such. OTOH, military went balls to the walls for jet tech... I simply assume that everybody used radials for a good while because they were all over the place.
I'm sure he must have enough pitch on those props to give the engine a bit of a workout. What I don't understand is why the trailer doesn't fly off in to the horizon.
@sniper50cal2 If it only had one prop the engine would try to rotate the opposite way to the prop and the whole thing would spin around (think helicopter with no tail rotor) so having an extra counter-rotating prop balances out the rotational forces.
why arent there any comments dismissing civics or any other japanese cars? as the amount of these comments seems to increase as the displacement increases
Counter-rotating props not withstanding, This engine was fitted to some recon. Spitfires because even though it was a bigger engine it didn't have a supercharger and was more efficient.
yah its true the drag cars i'm sure are louder, but i think because they get a lot more power from a smaller engine, and they run nitros in them too. the big dragsters get from 4k to 8K HP I think this one gets only about 2000 HP and its made to last a long time. anyways if these guys would've reved this engine to maximum RPM would've sound a lot different for a moment.... LOL
These aircraft engines really aren't THAT loud. Cars at the drag strip make more noise. If 50 cc intimidates you maybe a quieter activity is in order. As to what they are thinking is probably WOO HOO!!!! look at our big ass engine!!!
question. are the counter rotating props a more recent addition or were there some models of aircraft equiped with counter rotating props during WWII? Because ive seen a few pictures of P-51 and spitfires equiped with counter rotating props. and before anyone gets all upity and jumps down my throat i know that the griffin wasnt the power plant in either of those aircraft THANKS
@will79601 The Merlin had a hotter cam than the Griffon. The Griffon has a different firing order for the cylinders than the Merlin and that gave it a much beefier sound.
@59cva It's their time and their money, not yours. It's a running display, usually made from engines/parts that no longer can be used for airworthy use.
what did this power and what is the mpg i love at 1:03 when he revs it u seen each cyclinder pop. if i had any more footage of the other side i should be able to work out the firing order
@alexjohnston1981 Hobbyist and mechanical enthusiasts restore the engines for running display, usually from engines that can't pass inspection for airworthy use anymore.
@dwnrety1 There's a few You Tube videos of The Green Monster, restored from the 1950s and using an Allison V12. I don't see any new videos of a race so I guess they just ran it for the crowd. There is a historical 1958 NHRA film Ingenuity In Action that has The Green Monster making a pass at 170 MPH and smoking the tires at least halfway down the track.
These big V12's are very hard to find anymore....they are great engines. Thanks, a great video

Just listening to that V12 at full throttle sends a shiver down my spine. Better than the best music. I guess it has direct fuel injection, 4 valves per cylinder and 36 spark plugs.
The Contra rotating Rolls Royce Griffin engine.
The ultimate hair dryer
right on running an engine doesn't need any kind of purpose what so ever..way to break social convention. these men are pioneers.
I love the backfiring, it sounds so cool and that galloping sound too
looks like the props are pushing against each other for the engine to have something to work against. That beast in a plane

gotta love the flames and crackling on the overrun.
These old girls will still run, when turbofans are allready on the scrapyard! When we are flying jet cars, these babies still fucking run!

Sounds fantastic. Now all it needs is a MK14 spitfire wrapped around it to make it complete.
one of the best, if not THE very best aero engine of world war two.

Well, you're wrong.
Contra rotating props are used to counter engine torque effects and to maximize aerodynamic effeciency.
nope....don't need a shower ma .... just had the stink blowed off me. cheers from Delaware, u.s.a. she sounds great.
That is an awesome setup! I wonder how it'd work in a PUSHER config and mounted on an aluminum flat bottomed airboat hull.

Yeah he was into them for years he now owns a Lexus......at least the Capri was British.
@sniper50cal2 If it only had one prop the engine would try to rotate the opposite way to the prop and the whole thing would spin around (think helicopter with no tail rotor) so having an extra counter-rotating prop balances out the rotational forces.
@helgih580
No, they are turning in opposite directions from the contra-propeller design for the Griffon engine.
Cool, two counter-rotating propellers. What kind of In of aircraft was it used for?
why arent there any comments dismissing civics or any other japanese cars? as the amount of these comments seems to increase as the displacement increases
that trailer must of been well and truely fixed to the ground
the blades are counter-rotating. it would fly straight, kinda like a chinook helicopter. an duh it wouldnt survive, thats why its fun
Counter-rotating props not withstanding, This engine was fitted to some recon. Spitfires because even though it was a bigger engine it didn't have a supercharger and was more efficient.
Funny, first thing I thought, too. That, and, I'm glad those prop blades are cut down...
it was originally on the Supermarine Spitfire and saw its first use there
It's a Rolls Royce engine.
Awesome engine. Better hope those props don't chuck something backwards and take your head off though!!
i guess thats one way to cool down the house in summer :D
The 27 litre Merlin produced maximum power at 3000 rpm, i would imagine the Griffon was the same.
Somebody knows how to build a motor :-) Very nice indeed.
yah its true the drag cars i'm sure are louder, but i think because they get a lot more power from a smaller engine, and they run nitros in them too. the big dragsters get from 4k to 8K HP I think this one gets only about 2000 HP and its made to last a long time. anyways if these guys would've reved this engine to maximum RPM would've sound a lot different for a moment.... LOL
The Griffon 65 was used in the Mark 14 and Mark 18 Spitfires but to late to see action in the war.
"JUST DROOL AT IT"
These aircraft engines really aren't THAT loud. Cars at the drag strip make more noise. If 50 cc intimidates you maybe a quieter activity is in order. As to what they are thinking is probably WOO HOO!!!! look at our big ass engine!!!
It needs steering and some brakes and it's good to go. Do a lap in Nurburgring in that guys. Please.
dam man..that thing will never get off the ground...
nope the CSU on the prop can turn the blade into the wind so almost no thrust is produced
Wouldn't that make the coolest air boat engine!!
sound's like the old vw transporter 2.4 from the early 90's :P
question. are the counter rotating props a more recent addition or were there some models of aircraft equiped with counter rotating props during WWII? Because ive seen a few pictures of P-51 and spitfires equiped with counter rotating props. and before anyone gets all upity and jumps down my throat i know that the griffin wasnt the power plant in either of those aircraft

There is a historical 1958 NHRA film Ingenuity In Action that has The Green Monster making a pass at 170 MPH and smoking the tires at least halfway down the track.
