Precious Metal P-51 Griffon Engine Test Run #1 2013

[@NoFrameHell]

What a beautiful piece of machinery!

[@marecanine]

Just think how beautiful she will be after she gets all of her make-up on and he hair done!

[@billwelter4101]

The late Spitfires had Griffons, but they seem to do fine in the P51 also!! Kudos for the team for getting the bomber engine and props in that airframe! What a prop-drive! Amazing machine!

[@peter.a.langan5872]

That engine sounds very sweet and well balanced. Plenty of power there too.

[@KevinMichaelCallihan]

In my "bucket list" of things to do before I die! Fascinating history with Rolls-Royce, always!

[@tattrie17]

What a beautiful bird! I could listen to that all day.

[@tulockthewerewolf9744]

Gorgeous engine

[@dtardis]

It's an amazing plane to watch!

[@profcarlosgomes]

Amazing!!! Fantastic!!!

[@Shellcool]

Wait you're telling me there's a P51 out there with a Grif shoehorned into it, I love it :D Now there's a proper competitor for the late Spitfires

[@FiveCentsPlease]

+shellcool0wns Several racing Mustangs have flown with Griffons.

[@Shellcool]

@@FiveCentsPlease I love it 🤣 they must be epic

[@FiveCentsPlease]

@@Shellcool From memory, there are several. The plane in the video was severely burned from a fuel line fire. It is being rebuilt but I have recently read that it is going back to stock condition. mlttzvmsup4k.i.optimole.com/5JfZEXg-0TdUpbs6/w:auto/h:auto/q:auto/airshowstuff.com/v4/wp-content/uploads/2015/09/11927484_575791245894918_7820596974380904207_o.jpg Then there was the Red Baron--crashed and destroyed, not fatal. I think parts of the wreck still exist and someone was thinking of building it. upload.wikimedia.org/wikipedia/commons/d/df/RB-51_in_the_Reno_Pits.jpg Also there was Miss Ashley II. Look closely at the wings and tail, they are from a Learjet. Miss Ashley II disintegrated into pieces during the Reno 1999 race, fatal to the pilot. i.redd.it/ypsw0wem0j511.jpg They may be other Griffon Mustangs but I'll need to look that up.

[@Shellcool]

@@FiveCentsPlease wow thanks for the info, lovely planes and sad crashes :(

[@panther105]

I'd love to see a computer simulation of the airflow pattern through those counter-rotating props. Was it really so much more efficient than a single blade propeller?

[@TheLawnWanderer]

10-20% more efficient in general.

[@GGigabiteM]

panther105 The correct term is contra-rotating or coaxial propellers since they're on the same axis (one behind the other.) Counter rotating propellers would be like on the P38 Lightning where the port and starboard propellers rotate in opposite directions away from each other.

[@panther105]

Jeez...!! I sound like such know-it all. Anyway, in the miltary and especially combat situations SIMPLE IS BEST....More gears whizzing around trying to stay lubricated and not grind into each other is the main reason we don't have a lot of this kind of propellor arrangement in history or even now when we have more exacting computer controlled machining. Amazing tech though. Practically anything we can imagine these days was already thought of and probably made into a working model decades ago. In terms of mechanical tech, we haven't really gone much further than the basic mechanism we had over 100 years ago. And, if you really look way back, you will find the Egyptians, Greeks and Chinese had it all the basic stuff worked out millenia ago....

[@GGigabiteM]

panther105 There are several methods of driving coaxial propellers, some being more reliable than others. But overall like you said, there's additional complexity. Many coaxial gearboxes were unreliable and could result in spectacular failure with one or both propellers parting company from the plane or getting stuck and acting like a huge airbrake. The reason that coaxial propellers aren't in use today is because there's few applications for them. The only two major applications for them in modern times are the bear bomber and various helicopters.

[@svenlittlecross]

panther105 its not only the efficiency its also that it negates propeller torque.. for example seafire planes during the ww2 had difficulties with aircraft takeoff cause of the torque(a propeller pull in the opposite side of the rotation direction)

[@evertpluim]

Stunning

[@tommyboy1845]

That's impressive....hot rods of the sky..

[@stanarmstrong1020]

One mean engine!

[@robertlafnear4865]

From me you get a " REALLY NICE " looking plane !.... and the engine is the cherry on the cake as they say !!

[@groomlake51]

It’s crazy how hard super high octane fuel is almost impossible to start cold. That’s why we use cheap 87 to start Top Fuel Nitro engines.

[@ykb946]

That's Awesome!

[@jaarryifleshblood315]

People that put Thumbs down are people that hate old planes

[@Appalling68]

Jesus H. christ....contra rotating propellers!! I have never seen this in a modified warbird. This freakin blows my mind!!

[@Bagheera2]

They had to, Torque on that thing would be retarded.

[@stevethomas-cc5lz]

actually, howard hughes did it back in the late 40s.

[@michaelnaisbitt1639]

Appalling68 it's not a Warbird. No griffon powered Mustangs ever saw combat in either WW 2 or Korea. This is purely for racing the contra props were supposed to counter take off swing of griffon motors

[@Appalling68]

Michael Naisbitt Well if you must split hairs. The P-51 is a "warbird." Obviously the P-51 was originally built with the Packard Merlin engine. You did notice my use of the word "modified", right?

[@kenjohan]

Can't be much of an explosion when your tiny mind explodes.

[@HotSpace2007DaveB]

Can you imagine that engine on that plane going after Me-262's 👍

[@BadAssEngineering]

Why don't you guys use TurboProps? is it because of Horsepower, or rules, or just sound and vintage-ity?

[@dedmunds2323]

Rules, Piston engines only

[@5000mahmud]

@@dedmunds2323 As it should be. Turboprops would make it too easy.

[@existentialerasure]

Great frame rate for those props. It looks like they are generating demonic energy. The Contra Rotating props and the raked wings, amazing airplane!

[@kirbyyork425]

Great idea, I'd love 2 build a P-51 Mustang and put a Griffon engine in that, but paint it more like original colors from the war.

[@mickemike2148]

I notice seven thumbs down and wonder why?

[@MikeKillian]

Because some people are stupid and don't know cool if it slapped them in the face

[@rarebear7788]

Micke Mike, because some people are scumbags.

Clever were these RR guys, and with Ilmor and others the edge remains.

[@beagle7622]

Love the fire extinguisher . If that thing blew up you would need a fire truck , what a machine

[@martintynan4114]

I always wondered why a griffon variant wasn't at least tested during the war.

[@viper8red]

Cost and complexity of serviceability.

[@blockheadgreen_]

Its 'cos the griffon was exclusevly built for the spitfire at the time.

[@robstewart5706]

Martin Tynan They did ,but just ran out of war.THey even looked at really changing things by putting a Griffon mid engine like an Aircobra.Called a TBF ,"The Big Fighter".Never got off the drawing board.War was ending and Jets were starting

[@kenjohan]

Not exactly true. Fairey Firefly and Fairey Barracuda used it as well and there were probably more types equipped with the R/R Griffon Engine.

[@davidparry8514]

pilots were cheaper

[@peterehmann4417]

sweet rolls royce merlin sound,i love it

[@ValiRossi]

It's a Rolls Griffon. Much bigger engine.

[@QG-vz4qg]

That's my favorite air racer. Because this plane has double propeller

[@anderstrygg639]

Thom !! U are Doing something special, and U know it !! Good luck in 2014 and see U un a couple of weeks :-)

[@viruspter1dactl]

Why the duel prop?

[@FiveCentsPlease]

+ viirus Pter1dactle Contra-props are more efficient. They are also safer for high-power single-engine aircraft, eliminating dangerous torque that affects handling.

[@viruspter1dactl]

@@FiveCentsPlease yeah I know now

[@tadpoled9928]

I often make fun of how stupid the general public is, but I see a beautiful piece of art like this and I realize that humans have done incredible things.... I just wish more people appreciated these engineering feats.

[@brentbeggs7413]

what happened to it?

[@FiveCentsPlease]

+Brent Breggs It suffered a fire during a refueling stop, if I recall it was a high pressure fuel line. The damage was worse than originally thought but it is being rebuilt. I'm hearing that it might be going back to stock.

[@Apyr404]

come on some one tell him to engage wep pls need to realy hear the griffon roar

[@jackmunday7602]

Just imagine if the Allies were able to introduce such a machine during the war.

[@Kyleinasailing]

I presume the engine is from an old Shackleton.

[@GriffonGrowl]

Or a Super Marine Spitfire

[@aerialcat1]

Family and friends wanted to know why I bought a Harley at my age... because I couldn’t afford one of these.

[@Reichiruu]

I want one :)

[@alcijohontavares3697]

Nossa que máquina 🇧🇷🇧🇷👍

[@robertphillips3078]

The P51 Mustang never came with this Engine Originally. How good were the Brits & Rolls Royce 4 the design & development of the Big Griffon contra rotating props The original mustangs had Packard junkyard engines. Untill the Yanks asked Britian if they could build the Merlin Engine in the usa. Obviously these chaps have really gotten alot more HP out of the Engine than 70 yrs ago

I find the avatar being used by Martin Tynan completely offensive. What sort of person does this. I mean, a fucking SWASTIKA??

[@SEAL52]

swastika is a luck charm in far eastern culture.

[@b4lbuz]

SEAL52 And they use it on a red and white background too ?

[@ToolofSociety]

b4lbuz Yes way before the nazis took it.

[@427SuperSnake1]

The swastika is actually a religious symbol friend. Just because hitler used it does not change what it's original meaning was before he adopted it.

[@adrianlarkins7259]

+427SuperSnake1 You are right, It was and still is a religious symbol in the East but you are wrong if you honestly believe Martin Tynan is using it for that purpose. He is waving the Nazi Flag, make no mistake. The swastika comes in many colors and styles. Odd is it not he chooses the Nazi.
