sestavení motoru v12 merlin včetně jednotlivých šroubů. Sestava obsahuje přes 1200 dílů. Toto není oficiální motor, je to pouze 5x zmenšený a zjednodušený model, ale velmi verně napodobený opravdovému. - Ігри
They designed and built these buggers and stuck them in aircraft weighing at least 7000 lbs that flew 400 mph. OVER 80 YEARS AGO! That boggles my mind.
Merlin cams were driven by shaft and bevel gears, not spur gear train.
I am working on a BSA Triple now, I find it amazing but a Merlin would be fantastic.. just to see one apart would make a dream come true for me, I have seen a couple of Engines but not the inside parts.
I have never worked on a Merlin engine, but the Rolls-Royce film I saw showing Merlins being built showed that the supercharger housing was cast integral with the crankcase and not bolted on.
Merlin has 4 valves per cylinder...
Beautiful engine!
Good fun. Have a look at the videos of my engine and you can see the set up of the trailer as well.
Despite the nit-picking, I was amazed by this.
Excellent!
Well Done! Bravo
Old school CGI but still effective. We can see the components and their function. Really cool engine and a legendary one. I didn't know it was single overhead cam. This thing produced some 2,000 HP for the P51D Mustang?
People are saying its not accurate. It says in the description "This is not an official engine" The video wasnt made to be accurate.
A good effort Mike, gives a general appraisal.
Thank you Mike, I'd made a comment earlier re Rotax mags SU carb etc, but not in a critical way. I've worked on the engines, & Spitfires up to about 2005, & I wanted to answer one of the comments. Re. 4valves per cylinder, & rocker fingers twix sohc & valves. Keep up the good work👍
I got to take a tour of the R/R aircraft engine rebuild facility in Livonia Michigan. I was surprised at how small and fragile the cam shafts we're with very little lift and small valves too! But the connecting rods we're really different from let's say a auto engine. You guys that are familiar with the Rolls did they design them that way to save on the overall length of the power package? One more question did the Aillison engine used in let's say the P-38 have the same type of rod design? Thanks.
Can you do one on the ALLISON V1710 ?
Let’s see how wrong you can get that.
Interesting work, but why the inaccuracies?
Je suis un fan du moteur Rolls Royce Merlin. Un prodige de technologie. Et une sonorité sans pareille. Et ne pas oublier l'histoire incroyable et insolite de Miss Tilly Shilling dont l'une des trouvailles nommée affectueusement par les pilotes: "Miss Shilling's orifice" a eu une importance déterminante dans les performances liées à ce prodigieux moteur d'avion.
Can you make a video of rolls Royce Crecy? Very informative animation btw.
What a magnificent piece of engineering made in their ten of thousands decades before
C.A.D. and C.N.C. was ever dreamed of. It might not be an accurate representation but it gives an idea of it's complexity.
That's the first useful comment yet!
Not even remotely close, but entertaining nonetheless!
NOT a Merlin: e.g. Merlin has 4 valves/cylinder that are canted at 45 degrees.
the valvetrain looks different to the real one.
Nice piece of work. Too bad the inacurate title solicited so many negative comments. Can't you rename it and release it anew?
Good work, but Merlin engine is 4 valves each cylinder, not 2 valve.
The number of piston rings is also incorrect.
This is only model of engine in 1:5
at the engine i had in the workshop i saw that there was twinspark maybe made to make the plane to return home even if a sparkplug or two failed
Exactly what I was going to say!!..Spot on!.
The merlin had overhead cams.
Nothing like. I stripped one for the crank and rods once (brother in law was a tractor puller)
Northern European genius.
That is not the manner the camshaft was driven in a Merlin engine.
you are correct camshaft were driven by bevel shaft
@soaringtractor From where did you take V1710, this animation is titled as Merlin V12 engine. In merlin engine camshaft is driven by vertical shaft and bevel gear.
Excelent!
The official Rolls-Royce Merlin V12 demo film states that the engine, including super-charger, has over 11000 parts, not 1200
correct
that's if you're counting individual screws as parts, which I think is misleading
すごい！組み立てれる気がしない。
4 valves per cylinder not 2 if you can't do it right take it off
Merlin had 4 valves per cylinder with single cam on each head
good video
Fantastic
Anything but a Merlin.
Wasn’t the Merlin DOHC 4valves per cylinder?
Yes 4 valves per cylinder,operated by rocker fingers off the sohc. It's a nice film, but the compressor on the tail of B bank not shown, also, the 2 Rotax magnetos, the twin choke SU carb, that fed the superchargers not shown. Not picking holes, as there are different mods depending on type number.. Also it's a few years since i worked on them. Thanks, good effort
Nice, but it is not a Merlin engine ...
"V12 Merlin engine" No, it isn't.
BINGO! The Merlin they have in the museum in Oshkosh has a vertical drive gear for the cam shaft with bevel gears making the 90° turn. When I saw the eleven gear cluster I knew it wasn't. Of course the blurb below title says, "This is not an official engine."
En chematisk V 12 som inte mycket stämmer mot Merlin. Kamdrivning o magneter bland annat.
Nice video but The Rolls-Royce Merlin engine has four valves per cylinder not two!
Good, now do a FEA on this.
The only reason I watched this whole video was to count all the inaccuracies, I stopped at a 125
Do the Titanic as a catamaran next. Curious, why call this thing a Merlin?
i had a rolls royce engine standing in the corner in my workshop i think it was a meteor we couldnt move it with the forklift it was to heavy it was a lefthand tractor engine
the rolls royce engines was made to left and right tractor dep on the use fighter planes are dif from tanks tractor dont mean a farm tractor but the way the engine pulls left or right
I drived my tractor left-hand and I crash ...my village went starving and kill me.... I cry for three days :(
How can you cry if you're dead?
Oh I is alive again after CRP
junto con bentley rolls royce toda la vida a años de los demas inglaterra siempre superior
this is nothing like a merlin merlin has bevel driven sohc 4 valves per cyl 24 spark plugs dual magnetos and a big blower at the rear where the timing gear case is
@soaringtractor nah you are wrong ive owned merlin 66 and meteor tank engine variation
allison was a pile of junk that why you fitted merlins to your mustangs
any how germans were way ahead with the me 109 motor
Interesting that it shows detail such as the Piston Pin retainers but doesn't show valve springs. It shows a detailed accounting of every other little part in the valve train system. Poorly done rendition of a fabulous and quite historic engine!!!
a lot of parts missing.
Not Merlin so what is it
This is not a Rolls Royce Merlin...
It's not a MOTOR, it's an ENGINE ! Motors run on electricity, Engines run on gasoline, diesel or steam....
yep and the gasoline engine also known as a otto motor made by Nicolaus august otto
I think most people would consider it an engine......
...and further, this is a ridiculous semantic argument. If you want to get REAL technical, with combined engines, the first provider of power is the prime mover...so does that mean that a diesel-electric locomotive should be a diesel loco-engine? Who gives a s***...semantics always crack me up, and the people who are most obsessed with them are engineers. (No disrespect to engineers, it's their job...but can still be funny).
Jacques Bloques or at least those that NEED to be right...I find it quite entertaining.
Quite interesting, but not accurate. Keep on with it, though.
The Allison v 12 was actually a more efficient engine design. The problem was the the Merlin had a superior supercharger. Had the mounted the Merlin's supercharger on the Allison it would have dominated all the watercooled engines of the war, but Britain would agree to that. Too bad. Could you imagine the extra potential in the Mustang? Or how about the much Maligned Aircobra or SuperCobra? Both of which had far less aerodynamic drag than the Mustang. They would have torn up the skies. The Aircobra was a worldbeating design until the Army Air Corps got a hold of the design and removed the American supercharger from the engine and then weighed it down with extra armament. That took a radically new design and relegated it to ground attack status, where the Russians found it more than capable of beating their German counterparts. With the re designed P63 SuperCobra the Russians had a world beater. Sure, the aircraft had different spin characteristics than their front engined counter parts, but after proper training it functioned just as well as any other plane in the skies during WWII. And the first ever swept wing American aircraft was a converted P39, used by the Navy too evaluate the swept wing concept. With the engine mid mounted, like all the jet fighters around the world today it gave the Navy everything it needed to developed the contemporary swept wing jet fighter! Also, every P51 air racer today uses Allison connecting rods intheir Merlin engines for strength and reliability. Without the extra strength the radio engined racers would be dominating the skies on race day!
Never heard that the Allison engine had a supercharger. Some models were fitted with turbo-chargers. Like in the P-38.
The Army Air Corp really didn't want the the P-39 or its later version the P-63. They felt that the installation was too complicated to be maintained in combat units.
Engine behind the pilot. A gearbox on the front to drop the power flange beneath the pilot, a long drive shaft with support bearings, U-joints, and another gearbox to connect the driveshaft to the propeller.
Not only would the aircraft be a PITA to maintain in combat, but it would have been a beast to build in large numbers.
Without a blower of some kind, the aircraft would have been useless in the ETO.
stronger rods in the allison apart from that it was a boat anchor, merlin developed 1650hp in its final guise reliably too thats why they put them in p51 mustangs
soaringtractor ______ Fuck off Wilbur.
Why go to all that trouble, when it’s not like a Merlin engine at all! The Merlin had four valves per cylinder and the the camshafts were driven by a bevel gear and shaft arrangement. This is miss-leading and should be removed.
That doesn't look right.
boy this is the most inaccurate representation of how a merlin is assembled ,, i can state just a few of the inaccuracies ,, for instance the HEAD is bolted to the Cylinder block from below and the cylinder block bolted to the upper crank case ,,,,I have worked on both an allison V-1710-10 and and a packard merlin as well ,,i've been an engine collector since the 90s and have a huge collection of engines from the 1930s through the 80s including several aircraft engines and the allison which my grandfather had buried in his garage since the 50s ,found the merlin in a barn in 1992 hidden in a trailer full of junk, ,it had been restored and all it needed to run was some tinkering and a set of sparkplugs ,,,I also recently acquired something more interesting and that's a ford GAA which was used in the sherman tank ,,but was originally designed by FORD as a V12 airplane engine prior to WW2 ,,it was the FIRST monoblock V12 engine built like a modern engine today , dual overhead camshafts liquid cooled but the airfarce decided radial engines were better so it was overlooked and it ended up coming back in redesigned form as the GAA which is a V8 the very first dual overhead camshaft V8 engine and produces 400HP and 1200 pound feet of torque out of 1000 cubic inches ua-cam.com/video/cQWQm1zwVZ8/v-deo.html
Merlin was a weaker and smaller engine than the German DB605 that’s why it needed the high octane American fuels 100 to 150 while the Germans used cheaper 87 octane. Truth is brits lost the Battle of Britain. You cannot say you won when you go begging the world for help. Why on earth were the Canadians and Australians flying spitfires? Spitfire also ran cheap carburetor for a while the British leave out everything that doesn’t benefit them
Any onewho negged this was being pretty disrespectful TBH.
That's not a Merlin. facebook.com/Stallion51FlightOperations/
head design is wrong, Merlin like the Allison had 4 valves per cylinder.. not 2
