Sound of Merlin engine

Sound of the Merlin engine during Battle of Britain 75th anniversary event at RAF Museum in London.

That's one hell of a fan you got there

[@monkeyballz168]

Could do with that in my house rn

[@DurhamXo]

A super fan some may say

[@HistoricAeroEngines]

Great video; thanks for uploading. I could not see the audience behind me and only realised how much they enjoyed the blast when I see these videos!

[@rafalrazmus]

+David Were you there on this particular show? Sunday at 12.30?

[@HistoricAeroEngines]

+Rafal Razmus Yes. I'm the guy running the engine.

[@rafalrazmus]

+David Wow! Good to know :). Thanks for the great show.

[@Icepacalapse]

I just like that you have a proper propeller on it and blow the hats off the crowd.

[@MartinPaulo]

I suspect that it's there to keep the cooling system working...

[@matthewmcpherson7535]

Nothing beats hearing the merlin fire up and the smell of the exhaust and fuel for the first time was amazing.

[@cellpat7392]

one of the sounds that won a world war. thank you RR.

[@DarthKanye]

I’m no mechanic, but this sound is truly nice.

[@bennickss]

Alongside the ‘whistling’ English electric diesel engines used in the class 20/40 and the roaring Deltic, this is one of the best engine sounds that I’ve ever heard

[@NJPurling]

Because it is the sound of Freedom. When it is the chorus of a four as on the Avro Lancaster Your goose-pimples will have goose-pimples and your hair will be standing vertically. In 1940 most air-planes were rather slow. A Spitfire was pretty much the equivalent of a top-class racing car with wings & guns.

[@macmac8249]

That is a smooth running engine . Whoever rebuilt or refurbished it (if it WAS redone) put a lot of love into it.

[@oliveringram3056]

Ran sweet as a nut. No smoke, unburnt fuel etc. Well set up.

[@ronlafitte6864]

Wow! What a fabulous sound!

[@jonathanolsen7254]

when he put his left leg up it looked like he was going to pull start it, Love this motor....ROCK ON>>>

[@thestig8133]

The Griffin is really nice but, the Merlin is something else SPECTACULAR!!!! that's why it's my all time favourite sounding engine in the world & will go on always being so.

[@InfiniteLaundry]

Im a big fan

[@tombrydson781]

Lovely sound

[@jaygatz5980]

The sound of victory….

[@DeputatKaktus]

This sounds sooooo smooth - and thinking that this engine was probably not even running at 1/3 of what it is capable of…I wonder if it is even possible to really give it some beans when it is not firmly bolted down somewhere. Assuming that the owner would even be willing to go „full tilt“ with this no doubt insanely expensive and exceedingly rare piece of machinery. Really curious to know if this engine (or any one like it) ever saw full throttle after its service in the war.

[@HistoricAeroEngines]

We display Merlins at 2,250rpm (max being 3,000), but at low boost pressure. Actual delivered horsepower at the propeller is not more than 500hp (this engine is rated at 1,620 hp). In pre-season testing this engine will be run at higher speeds and power, but still barely a third of the maximum. An airworthy aero engine needs to demonstrate full power as part of its check-out for flight, so all Merlins flying will have passed that test.

[@andybelcher1767]

Ask Guy Martin... 🤣🤣🤣🤣

[@IamScoHo]

There will be a day when we won't use combustion engines anymore. And I'm ok with that. But I'm so glad that the age of internal combustion overlapped with mass recording because I could listen to this and race cars all day long.

[@mnx-p1]

That kid on the left at 0:50 though

[@johnelcock7734]

That guy is having way too much fun

[@HistoricAeroEngines]

I certainly was ;-)

[@UberStrikerful]

I haven't heard a Merlin engine running on 100% throttle or even WEP yet... Or was it running near that threshold in this video? Either way, sounds great. I can use this to contrast the awful Merlin engine sounds Gaijin uses in War Thunder

[@HistoricAeroEngines]

Kensta: I only just read your question. I run the engine at a very modest power, engine speed never exceeds 2,300 rpm, with -2.5psi boost pressure. This translates to about 550 hp only. This engine can deliver 1,620 hp at 3,000 rpm and +18psi boost, but that is far above the design limit for the trailer and well in excess of what I want to achieve with a nearby audience. Have a look at my other videos, and you will see other runs.

[@UberStrikerful]

Hmm I see.... I'll go take a look then

[@FiveCentsPlease]

+Kensta Without the load from a full size prop, you can overspeed these engines and they can come apart. Very unlikely to see full power on a trailer unless it is a test with a normal prop.

[@globalitykowzel_8223]

Magnifique excellent !!!!!!!!!!!!!

[@HistoricAeroEngines]

Glad you like it :-)

[@smolchungus5647]

*flies away*

[@DurhamXo]

Got you a new hair dryer pet

[@richardseidler7438]

I wonder how many rpms that propeller turns at full throttle?

[@HistoricAeroEngines]

Propeller RPM is geared to the crankshaft. On this Merlin, the propeller is geared at 42 percent of the crankshaft speed. Engine max RPM is 3,000 therefore the maximum propeller rpm is 1,260rpm.

[@brucerosati9434]

What, no kicker?

[@glblb3030]

thats a beast

[@2005-q6h]

You think you can fit that in a Miata

[@leemday5731]

Are! Let's see! all we need now is a fuselage two wings a tail and and 4,hispano canons! Then there its is...marvelous!

[@timmorahan304]

Awesome

[@s.brekke2285]

As horrible as war and destruction is.....to hear 100..200+ bombers fly overhead loaded headed across the channel...all powered by these incredible Merlins...had to be inspiring.awesome.frightening

[@trenttipton3876]

If that was a cold start whoever set up the tune on that motor needs a POB

[@HistoricAeroEngines]

Thank you ;-) Have a look at our Facebook page and u tube channel for more content and other engines.

[@macmac8249]

I don’t know what P.O.B. means but, if it means “darn good job”, I’ll have to agree 100% . That engine is a gem!

[@markolson2466]

Air moving at that speed HURTS! Ouch

[@troya4230]

Spitfire engine, right? :)

[@vincenthewlett4329]

sounds better than anything beethoven written.........

[@Jf72-j9r]

You just need to build a airplane for it.

[@LightStreamer]

he hardly opened the thing up. that was taxi power

[@Iron_Lion_Of_Zion]

Technically, thats not a Merlin. Its a Jasper. The cylinder head is a big giveaway. The Jaspers were produced right at the end of the war, when the RAF needed to have engines to keep the fleet of Spitfires flying, but did not need the out & out performance of the Merlin. The 2 engines have a TOTALLY different sound, & its only because many of the parts are interchangeable that this engine is wrongly claimed to be a ZXXIV Merlin. Beautiful engine all the same.

[@FiveCentsPlease]

+ Imran Ahmed They describe the exhibit as a 500 series Merlin that was rebuilt from a 24 series. So it would be late or post-war for civil use or for the CASA aircraft used in Spain.

[@HistoricAeroEngines]

This Merlin is a Mk500-29 and has a full history from its production in June/July 1943 as a Mk22 (Lancaster Mk1), and subsequent upgrade to T24-2 (Avro York) and then 500-29 (CASA2-111), authenticated by Rolls-Royce production records.

I don't think this sounded very good :/ not sure what I was expecting but this is just farty noise.. what am I missing?

[@rafalrazmus]

Well, I recorder it with a budget camcorder Panasonic V500. I guess if I had a better equipment the sound would be better.

[@Psychosix]

@@rafalrazmus maybe.. I'm not saying the quality is bad, its just up close they don't have the deep sound they do in the sky.

[@Defoggers_4545]

[@888jackflash]

Jay Leno's is better

[@macmac8249]

I don’t know if Jay Lenos engine is better or not (granted, he’s got a fancier test stand) but ALL of these old engines are great...no matter who has them. (The lucky devils). And bless the pilots who “drove” them to work.
