Beautiful. So complex and those old timers designed and built them without any computers. I will always admire their mastery and skill. Imagine what they would have done with the benefit of the technology we have today.

this is like taking a formula 1 car to get the shopping, these engines are designed to be in thin air at 40,000 feet doing 400mph, that is when the engine runs sweet... my dad used to watch then on night missions, a lovely blue [correct colour] exhaust flame either side...
Absolutely wonderful. What a brilliant piece of engineering and reconstruction knowledge, craft and skill. How sad and 😂hideous it had to be engineered and used in weapons of war. Why can’t people in power be tolerant of each other and celebrate and enjoy our differences. We have Spitfires from Biggin Hill flying over us almost daily through the summer & Autumn and it is impossible for us not to rush outside if not already there to see that beautiful plane and hear that amazing Merlin sound. We were lucky enough to go up in two Spitfires in 2023 from Biggin Hill to celebrate a big milestone in our lives and the part that engine and aircraft played in enabling us all to do that. Flying side by side in Spitfires waving at each other was just incredible. An utterly unforgettable and highly exciting and emotional experience. Huge thanks to you Klas for preserving these reminders of human endeavour and the horrors of war. John & Anne.
Or a mustang! I am american and love american aircraft but the mustang never would have been what it was without being by chance married to the merlin.
the man has an airplane engine on wheels he probably rebuilt it from 4 scrap engnes...he knows how to not kill it haha...besides it has a cooling system anyway see the radiator under the engine.
There's engineering and then there's the Merlin! It's mind boggling that people sat down one day and using slide rules and technical drawing (remember that?) designed and created a mechanical jigsaw that once completed in the correct order, won the Battle of Britain. That's next level creativity.
During WWII my dad was a mechanic and maintained Merlin engines. If I recall, each mechanic was responsible for just 1 engine. He also helped repair air frames when they came back "shot up".
if you knew anything about these engines you wouild recognise that is isnt running great. Follow the start up procedure and they always start right up ESPECIALLY when there is no load. Its actually running like shit. A pilot would shut it off and refuse to fly.
@philroe2363 I worked on nerline for 24 years at the Reno Air Races and with several sir meduems. Trust me, this Merlin is a wornout/timed out motor. A properly tuned Merlin would never have yellow fire coming from the exhaust. A well tuned Merlin would never make all that popping sound at idle and one certainly wouldn't have all that valve clatter
My dad was a pilot who learned to fly in the Navy in WWII. He said after the war, you could have got a P-51 for $500. I think it was the greatest regret of his life!
@@markpatton6847 one web site reports that a $1 from 1945 is $17.53 today. That would make that $500 plane worth $8,765. Still, a bargain in anybody's book I think.
Jay Leno would love to own that engine! He might be compelled to put into a custom vintage racer from the 1940s. Otherwise, that engine actually belongs in an aircraft that used them.
Yes.... and many of the young pilots who flew Spitfires and Hurricanes in the Battle of Britain of 1940 paid the ultimate price....the average survival time for a new pilot officer was just 4 weeks before being killed or injured/captured.......

The Merlin engine was designed and built by Rolls-Royce but, U S auto manufacturer Packard was licensed to manufacture the engine. The Packard engine was far superior over the Rolls manufactured engines. The US was far ahead in mass production where as companies like Rolls built engines one at a time that required many hours of hand fitting part like the heads to the block. Mechanics in the field couldn't go pull a head off of another Merlin engine and just bolt it on to an engine they were trying to get back in the fight without hours of hand fitting. With the American Packard version a mechanic could take a head or any engine part from a parts plane or new off the shelf and bolt it on and quickly getting the plane back in the fight
The Packard engine was NOT far superior. There were some modifications introduced sooner in the Packard such as the 2 piece block, but these were ultimately changed to the RR design. Packard built a very limited number of models and none of the final ultra-high performance kind such as the 2000HP ones. The toolkits however were fantastic. There were also a few tricks that Packard would not share with RR and vice versa. RR built over 30 000 more engines. The Packard Merlins were very good engines and slightly better in some ways.
I have a couple of questions. What were they winding up with the handle before the start attempt? When the engine was running there were not many oppurtunities to view the output/propeller shaft and when I did I could not detect if it was rotating. This may have been becouse of Stobe effect of course, but was it? The Merlin has a distinctive exhaust note which always makes one look up to see the aircraft when I have heard it in the past. In my youth I lived relatively near to an Airfield where RollsRoyce did experimental flights (Hucknall Aerodrome in Nottinghamshire) and strange things flew around a lot.
@tomas_klouda Pretty sure. Prototype versions used a Hercules engine, but they were considered underpowered and soon switched to a RR Griffon, then Merlin engines. Initial production in 1941 used a boosted Hercules IV engine, but due to shortages of those units the Mk.II Beaufighter used RR Merlins XX's (Mk.IIF I understand was the aircraft denomination). Apparently engine nacelles were designed to accept Hercules, Griffon, and Merlin Engines.
@@garyt123 Interesting. I only knew about some prototypes with Merlin, but they were not very succesfull, so I completely missed, they even created a production run with Merlins (Mk. II). Not sure how precise are the numbers I have found, but looks like from 5500 produced Beaufighters only some 340 were with Merlins. Engine nacelles were totally different for inline Merlin and for radial Hercules engines. You can clearly recognize aircraft with Merlins at first glance.
Beautiful sounding engine I'm just a little disappointed that he didn't really put the pedal to the metal there and crank that baby up like it's going to take off.
That's because the fueling on the left-hand bank of cylinders was much richer than the right, hence the noticeable yellow flames. Plus needs a better cooling system to maintain static runs like that:
Men Scroll.
Men See Engine.
Men Push Play.
Men Hear Engine.

Spitting fire. They should name an aeroplane after that!

Father flew Spits. He said the Merlin would make the cockpit dials a blur until it warmed up. The Packard was smooth at start up.

My Grandad made then engines and maintained them During ww2.
all his grankids are Mechanics..in the blood like .
Was the hand cranking to lubricate cylinders?
If it starts with a battery (I guess the blue box) what was the cranking for?
What’s the clockwork handle for ?
Beautiful sounding engine I'm just a little disappointed that he didn't really put the pedal to the metal there and crank that baby up like it's going to take off.
Without cooling, he will weld pistons with block of engine...it was just show for kids😂
Why does one bank of cylinders give flames out of the exhaust when the opposite bank does not?
That's because the fueling on the left-hand bank of cylinders was much richer than the right, hence the noticeable yellow flames.
Plus needs a better cooling system to maintain static runs like that:
No Replacement for Displacement 🔥
Seems like the engine was getting very hot.
Burning valves, possibly little sparks coming out of the exhaust ports
No cooling system hooked up
@@albertcyphers1532 there is a rad under the engine clearly getting hot with a water hose going in.
because it's overheating due to not being cooled correctly. He almost blew it up.
@@darthgardnerYep, too bad there is no electric fan drawing air through that radiator while the engine is stationary on the stand.
Don't think that would be valves....I'm pretty sure that's just unburnt fuel seen from the exhausts....
