Rolls-Royce Merlin Engine

[@millarlambie2970]

My Mother was trained by RR and worked on the Merlin project in Hillington While there she met my Father , he working in the experimental department On the jet engines. My Brother arrived in 41 then me in 1942. I had no idea of the scale of the Glasgow plant until I watched this video. RIP Mum and Dad.

I served my apprenticeship at RR Derby as a sheetmetal worker, 1968 to 1973. In my last year as a 19 year old I was sent to do a repair on the RR spitfire, which then had a Griffin engine and 5 blade prop. When I got to the hanger I found i only had to replace 3 countersunk rivets in a wing panel. Job done and signed off I was on cloud nine, It was such a privilege to be even asked to touch the thing let alone contribute to its up-keep. Keep them flying forever.

The merlin was no better "engineered" than any other engine of its day, actually the Allison, so maligned was a better more modern engine, larger, lighter, 1/2 the parts of a merlin and put out as much or more HP as a Merlin when equipted with the same or similiar supercharger. Yeah everybody points to the LATER merlin 60 as so great but in WWII Brits used over 2 times s many 20 series with the single stage supercharger, you see the merlin was used with THREE different superchargers, a single stage, up to the 20 series, a single stage with 2nd SPEED, NOT stage but SPEED supercharger, the most used version, and Finally in 1943 the 60 series 2 stage 2 speed version that is so drooled and slobbered ove, but it was only better ABOVE 20,000 ft, below the Allison kicked it @$$.

Think of the total ginormous number of war machines.. The waste of raw materials and life - why? Because there is always a mad man dictator and a willingness to try to live with such until it is not longer feasible. Recognizing the mad man early on would allow a defeat much cheaper in material and human life, but most politicians are appeasers not realistic until forced by circumstances. Since WWII we have seen this over and over and currently.

[@paulharvey4159]

What a beautiful machine, I live in Eastbourne and every year we have the airshow, and every year we have the spitfire on display, when it first passes over I look to the faces of the elderly spectators... The look on thier faces says it all, they cry, they salute and it fills me with admiration and awe. I'm a complete petrol head myself and when your back is against the wall with war on the horizon you end up inventing this! My fascinating fact about the spitfire. During testing they were obviously trying to squeeze as much speed out of it as possible, at one time they had it up to 350mph during a dive, they tuned the engine within a mm of its life, but it still wasn't fast enough, they retired to the drawing board once again... Gentlemen with pencils and pipes in hand, someone had the idea of perhaps gaining more speed if they line up the rivits so thier more streamlined and in a row..but that meant changing everything on the production line just to see if it would work or not, they used split peas! They actually stuck split peas to simulate the rivit heads in a line... Then turned the exhausts towards the rear to gain a bit of thrust... And got an extra 20 mph!... Genius! I'll be there again this year, can't wait to hear that machine go overhead once more... Peace and love everyone ✌️

[@barrierodliffe4155]

@@WilliamJones-Halibut-vq1fs All Merlin engines were Rolls Royce Merlin engines, Packard was well paid to make some of them which were copied from the Rolls Royce Merlin engine. Rolls Royce did all the development. The Spitfire Mk XVI was a Mk IX with the Packard copy.

[@WilliamJones-Halibut-vq1fs]

Barrie Rodliffe The Americans referred to their engines as V-1650 usually with a dash number after it eg V1650-3 which was approximately a Merlin 61 rather than Merlins. They may have referred to the as Merlins colloquially. The Allison was a V-1710. The Americans changed much of the engine such as adding a Stromberg throttle body swash plate carburetor, ignition system and many of the parts as part of Packard’s mass production standardization effort. Packard “merlins” came back with better tolerances. They were not interchangeable and Spitfires and Lancaster with Packard Merlins got their own mark numbers. Spitfires Mk XVI were Spitfire IX with a Packard Merlin. Making an exact copy would have slowed Americans down. The Americans made a water injected Merlin V-1650-7 for the P51H that could use 110/150 fuel. RR never did that.

[@barrierodliffe4155]

@@WilliamJones-Halibut-vq1fs The Packard copies were just that, nothing was changed. the Stromberg carburetor was a copy of the carburetor already used on Rolls Royce Merlin engines and given to Bendix Stromberg by Rolls Royce. Packard copied the mass produced Rolls Royce Merlin engine. Better tolerances is just a silly Myth. Rolls Royce made many more Merlin engines than Packard as well as al the Griffon engines and jet engines. How was Packard so slow. The P 51 H which had reliability problems and had the Packard copy of the Rolls Royce Merlin 130 engine which did work very well unlike the Packard copy.

[@blackpowder4016]

@@barrierodliffe4155 - Packard made several changes to the Rolls-Royce Merlin when going into production in the US. First was a two-piece cylinder block like the Allison V-1710. It reduced costs by reducing the number of rejected castings and making machining easier. Rolls-Royce later adopted their own two-piece block and Packard adopted their design. They also adopted a two-piece connecting rod like the Allison's instead of RR's famously unreliable three-piece unit. Modern builders almost always use the stronger Allison-style rod when rebuilding Merlins today. It allows higher rpm's. Packard changed the main bearings to the GM/Allison type which RR later adopted in the UK. Packard also cut the crankshaft output quill spline to fit the Wright Cyclone supercharger. The Cyclone supercharger had been in production for years, was reliable, and available in one and two speed models with single or dual stages. Since the Wright unit was meant for the 30 liter Cyclone it had spare capacity for the 27 liter Merlin. They were also widely available from several manufacturers as Wright, Pratt & Whitney Canada, Lycoming, and Studebaker all had them in production. At that time RR had not yet adapted the French Marman two-speed supercharger design so the decision gave Packard easy options for future applications. RR later changed the output quill on their own engines to a stronger spline design. Rolls-Royce used a Skinner Union carburetor early in the war. SU was a subsidiary of RR. The Bendix Stromberg PD12 throttle body fuel injector, also called a "pressure carburetor," was an American part used by Allison in the V-1710 and by Wright and Pratt & Whitney in their radial engines since 1936. It was not a RR part. You have that totally backwards. Packard adopted the PD-12 from the start and never used SU carbs which would have had to be imported. RR adopted the Bendix PD-12 in 1943 after first trying "Miss Shilling's orifice" as a stopgap measure on their SU carburetors. They came out with their own version later. As for the tolerances "myth," both Packard and British Ford found Rolls-Royce's specifications impossible. Their practice was to build parts to a loose spec then match over/under spec parts during assembly. A piston that was at the high end of tolerance would be put in a cylinder that was on the high end of tolerance and so forth. Some parts would be hand-finished to make them fit. Cylinder bores were all hand-honed by an expert craftsman. This reduced reject parts but required a lot more hand finishing. Both Packard and Ford had the capacity to machine to tighter tolerances so that any part would fit in any engine. No better an expert than RR's own Stanley Hooker wrote in his biography, Not Much of an Engineer, "In my enthusiasm, I considered that Rolls-Royce designs were the ne plus ultra, until the Ford Motor Co. in Britain was invited to manufacture the Merlin in the early days of the War. A number of Ford engineers arrived in Derby, and spent some months examining and familiarizing themselves with the drawings and manufacturing methods. One day their Chief Engineer appeared in (Merlin development head Cyril Lovesey's) office, which I was then sharing, and said, 'You know, we can't make the Merlin to these drawings.' "I replied loftily, 'I suppose that is because the drawing tolerances are too difficult for you, and you can't achieve the accuracy.' "'On the contrary,' he replied, 'the tolerances are far too wide for us. We make motor cars far more accurately than this. Every part on our car engines has to be interchangeable with the same part on any other engine, and hence all parts have to be made with extreme accuracy, far closer than you use. That is the only way we can achieve mass production.'" Packard's experiences were similar: ""As Robert J. Neal writes in Master Motor Builders, documenting Packard engines: "This was but the beginning of a monumental task of redesigning an engine which was not originally designed for mass production so that it could be made by American mass-production methods, and so that it could be fitted with American fittings and accessories as mentioned above [for example, carburetors, fuel pumps, generators and so on] or British accessories and fittings, depending upon which government the engine was intended for." Neal also notes that "Rolls-Royce's drawings did not specify tolerances and fits, and Packard had to take parts from an existing engine and make measurements to determine these specifications as best as they could, using engineering judgement where necessary." Of the total of 168,068 Merlin variants built, Rolls-Royce built the most at 82,117 but needed three factories to do it (32,377 at Derby, 26,065 at Crewe, and 23,675 at Glasgow). Packard produced 55,523 in their Detroit Grand Boulevard plant. Ford of Britain built 30,428 at its Manchester factory. Ford boasts the RAF never rejected a single one of their engines. (Note: These numbers vary slightly depending on the source.)

[@unclefester9113]

Staggering the amount of engineering that went into each of these engines. Each step.... explained in pretty good detail. They don't even mention that each of these processes needed to be perfected...... so even more steps in the design process.

[@fakevirus8828]

That's why they went to Glasgow ship builders to build them. They knew the ship builders had seen and done it all before and had a track record of banging out top notch engineering on the spot. Nobody else was qualified its as simple as that. They already knew what brutal weather and steep angles did to engines due to boats being basically the most brutal regime that any piece of metal has had to deal with out in the North Sea. What's more interesting is how bad the Germans where at building engines compared to us. They couldn't even get their war birds to fuel correctly under heavy G.

Wilbur Finnigan I do not agree, i think that R&R built almost tree times more these engines than Packard. At least I read so on Wiki.

[@wilburfinnigan2142]

Aleksandar Funduk Go back and re read the post. Total Merlin production from all sources was about 150,000 total units...Packard built 55,523. and Ford of England built 33,000 that is 88,000 that RR did not build. RR only built less than half the total production. And RR started building them in the mid 1930's and ended production in 1950. 14/15 years Packard made engines for four year and Ford of England about the same time. The facts man just the facts.....

"The initial Packard modifications were done on this engine by changing the main bearings from a copper lead alloy to a silver lead combination and featured indium plating. This had been developed by General Motors' Pontiac Division to prevent corrosion which was possible with lubricating oils that were used at that time. The bearing coating also improved break-in and load carrying ability of the surface. British engineering staff assigned to Packard were astonished at the suggestion but after tear down inspections on rigidly tested engines were convinced the new design offered a decided improvement."

In Canada and in Britain during the war, a certain percentage of the "Mechanics" and aircraft / aircraft engine / aircraft part assembly personnel were in fact well trained and well educated mechanical engineers with an aeronautical extension who were "working in the Trade" as apprentices to obtain the practical knowledge required in their new profession as inspector/certifiers as well as efficiency experts and production managers . In a large number of cases these civilians already had a "Trades" ticket as a qualified mechanic and were advancing both their education and themselves into higher roles - something that the Professional Engineering associations of today have no knowledge of, or chose to ignore.. The British called these people "Aeronautical Ground Engineers", Canada termed them "Air Engineers".. They have been a crucial and frequently mis-understood element in aviation safety in the United Kingdom and the Commonwealth nations since 1919. From 1948 onwards these people have been called "AMEs" and/or "Licensed AMEs".

Great video -- the Merlin was and is one of the great machines of that or any era. The first P-51's lacked high altitude performance and almost doomed the plane, but the installation of the Merlin transformed it into the long ranged fighter that was crucial to the Allies taking the war to Germany while saving thousands of bomber crews. Later versions of the Mustang used a Packard version of the Merlin licensed from RR.

[@ohger1]

Not close to "dooming" the plane. The Mustang as first delivered with the Alison was a superior fighter at low and medium altitudes. The problem was the Alison did not feature a two stage supercharger like the Merlin did, so it was not competitive at high altitudes where the bombers required escort. For instance, when the Merlin was installed in the P-40, there was no significant improvement over the Alison, and this was because the Merlin installed was not the two stage blower (didn't fit?). For reasons not fully understood, the U.S. gov would not fund GM (Alison) to develop an Alison two stage supercharger for high altitude. Perhaps they figured that the already well developed Merlin was as good as it was going to get and perhaps they were right. Also, the Alison would run much better at lower rpm than the Merlin, so if anything, the Alison had longer range.

[@LuisSoto-ho5fw]

John-Del thank you for that post. Too many people write off the first Mustangs and misunderstand the decision to go with the Merlin rather than design superchargers for the Allison. Also remember that Packard was already mass producing the Merlin for the British, so it was a no-brainer.

NA poured tons of aerodynamic concepts snd research into its design. However, we all know that the air war in Europe - from the allied bombing campaign perspective - was a high altitude war. Hence the experiment that led to that great marriage of airframe and powerplant (super convenient, as the Merlin was already being license built in the US). You also misunderstand the hows and whys of Packard (and Ford of UK) license building the Merlin. Remember that the "cottage" nature of British engine production - more focused on skilled builders hand crafting engines like precision watches - did not lend itself very well to war time needs. This is where those American companies came in, and an unprecedented engineering cooperation accross hemispheres was born. Both RR and Packard were constantly improving on the original design. This came much earlier than the Mustang, and most people are unaware of the surprising amount of Packard Merlins that were found in Lancasters, Mosquitos and some Hurricanes. Read Sir Stanley Hooker's book "Not Much of an Engineer." You'll find that an interesting read.

Brilliant insight into the most prestigious company to grace English soil. The attention to detail and perfection are quite staggering!

[@niczoom]

Great video! So interesting to see all the effort from everyone involved.

[@JohnS916]

Very fascinating and interesting how such an undertaking was accomplished. The technology of engine building was quite advanced for those years, I was impressed with the attention to the extreme detail in engine tolerances and build.

[@charlieross-BRM]

I'm about to watch the video for the first time. I am interested if there are any good close ups of the lathes, mills, etc. My father machined parts for Merlins and said they regularly worked to 1/2 thou' at RR. I would like to see what they had to work with to achieve that.

When I was working in UK, a BF109 crankshaft from an aircraft under restoration was submitted for inspection to a division of Rolls Royce for NDT and dimensional checks. The test report stated that the crankshaft was at nominal dimensions to the limits of accuracy of the tools used to check it. As well, the crank was produced near the end of the war when the factory was being regularly bombed by the Allies! That meant that German machinists were holding to 1/10,000th of an inch in bombed out buildings on machines that had been bombed as well (large machine tools generally survived all but a direct hit).

[@barrierodliffe4155]

When Germany was being bombed late in the war most manufacturing was dispersed just as it had been in England early in the war when Germany was bombing Britain.

Glad to see the equipment made in Saginaw Michigan.

[@37BopCity]

From that amazing company called Wickes, established in 1860, makers of the finest heavy mill machinery.

I've noticed "Poland" on a shoulder of one of the trainee pilots. Gave me a warm feeling.

[@michaeldicker4839]

pold poldecki. You should be proud too. Poland had the highest number of non Brits fighting in the Battle of Britain (145) and were formidable pilots. Thanks from a Brit.

[@MegaBoilermaker]

Had a couple of their own squadrons attached to the RAF Pold.

[@hughallen6621]

The Polish 303 squadron was by far the most effective during the Battle of Britain. Dowding himself acknowledged that without them the outcome could have been different. Their loss/kill ratio was the best in the RAF and they fought like lions, downing 126 German aircraft, for the loss of 18.. We should be proud and happy that Poles came to the UK to fight and now come to work. They earned it, many times over.

Interesting is showed a Avro Lincoln at 4:50, I wonder why it didn’t show the Lancaster. Also I thought the contra-rotating prop was only used on the Griffon engine which was developed from the ‘R’ engines in the SM S6B.

[@GLADYATOR109]

I can believe in my eyes. Thus documentary is masterpeice if we think the years that have ben made

[@j.edward4379]

I think the sound of a Rolls-Royce Merlin is the most beautiful sound in the world. In unlimited hydroplanes they growl and Roar. It sounds alive.
