Welcome.
This KZread channel is dedicated to sharing a passion of our group; the research, restoration and ground running of a collection of historic aero engines. The engines shown in these videos are privately owned and run by an international group of like minded aero engineering enthusiasts.
Some of these videos were recorded at public events where HAE were invited to ground run the engines. Events are attended on a non-profit basis with the hope of engaging as many public who freely visit our display to learn of our aero engineering heritage.
See our Facebook page for details, photos, videos and upcoming bookings, or contact us for more information. Thank you.

Lovely job. Well done.
Fantastic stuff,
Brilliant!
Can't be a radial. No oil. Little smoke. Well done Pat and collaborators.
tbf, look at the nearest oil/fuel tank :)
Paxman!!!!! ARRGGGHHHHHHHHHH!!!!!!
As an aircraft mechanic of 3.5 decades...I can tell you put your heart into this. Nice work!
The very reason headphones were invented 😊😊😊😊😊😊 music to my ears .
One of the most beautiful presentations of engine without airplane that I ever seen! It's so alive and angry!
think we built those merlin engines all those years back .No CNC then just very skilled people .
Indeed, and still some very skilled people today to keep them maintained and running.
wondeful sound 🙂
You guys must feel like kings after all the hard work there's very few people that understand what you went through to get this R-3350 Duplex-Cyclone running again great video guys
Absolutely stunning! ❤ this one sounds incredible and great operator!
All, please bow to The Mother of all Radial Engines and never forget the moment you hear, smell and see it come to life for the first time. Great to see this baby being restored..
Is there a piston on a spring in the rod journal thats compressed with oil pressure for rod bearing lubrication during inverted flight?
Are the rod journals hollow to store oil to be centrificaly fed to rod bearings during inverted flight?
Although the journals are actually hollow for weight reduction primarily, the proper answer is that they are not made for -1g extended inverted flight, it’s not necessary. The Daimler-Benz had direct fuel injection, but the lubrication system was no different to the Merlin in this respect.
Awesome to see this engine running. Huge respect to the team for the skill and dedication in preserving and displaying such important engines. Thank you.
To much music
The action starts in the middle of the video. However, for context, there is a reason for the music and introduction. The engines were acquired from a special effects company which supported the Star Wars movies. The music and intro is a nod to that heritage. Hope you enjoyed the action when it starts.
hi great job . just wondering what type engine oil was used in these . ie 15 40 type
The engines would have used Aeroshell 100 or equivalent. when flying. However given the ground operation, most engine use a straight 20w50 grade oil.
Excellent video Peter 👍
Thanks 👍
You look like TO BE OLIVER TWISTS SON ! Anyway from great USA AND PROUD
This guy fired up the engine and didn't move an inch. It was absolutely thrilling.
With this trailer the car will go faster.
need to roll that motor once a month
That baby chugs 2.5 gals of fuel per minute at full throttle
Are those chocks big enough to hold it? Lets see....
That sound brings tears to my old eyes. Flown by the greatest generation. I'm sorry recent governments have squandered your victory over invaders.
Why do Merlin's blow blue oil smoke on a cold start,do they have an oil priming system and no valve stem oil seals?
This Merlin does have a pre-start oil priming system built into the trailer, which is activated before the first run of the day. The primer pressurises oil through the maintenance point and passes up into the rocker assembly. The rocker oil drains back into the crankcase through drain ferrules, but given the inclined angle of the cylinder bank, some oil collects and can seep down worn valve guides. This is what appears as a burn off when starting. Display engines never generate high power, and the plugs do oil up, which adds to the puff on start.
That sounds soooo good.
In honor of the Tuskegee Airmen aka the “Redtails” Well done men, from a grateful Allied Forces.
I think Jay Leno has a set up like that.
True. Jay Leno has a Packard V1650-1 on a trailer. It was built by Graham White, a master engineer and aero engine expert, who has written several leading books on aero engine development. Mr White is also a member of our HAE group.
His neighbours must love him 😂
The intro created the perfect vibe for the gravity of rebuilding this monster. I haven't yet seen a rebuilt radial of this size come to life so spritely on the 1st go, it didn't even seem to want to settle below 2,000 rpm. Certainly no Chuk-ka-ta-chuck...cough smoke...weeze from this one.
In his book "Not much of an engineer" Stanley Hooker talked about a famous dispute between the RR and Ford. Having been assigned production of the Merlin, Ford motor company were sent the engineering blue prints which caused Ford a lot of consternation. So they rang up Lord Hives, boss of RR and protested that the incredibly generous tolerances of the Merlin were outrageous and would cause premature failure. Lord Hives was not impressed, and bluntly told them to just get on build them, and let RR worry about the longevity. They had a problem keeping the main or conrod caps tight, so they found a crashed german bf-109 and copied what the Germans did.
Ford UK at Trafford Park did indeed redraw the Merlin drawings to Ford's production standards following a conversation with Cyril Lovesey (not Hives). However, can you provide a reference to your comment regarding the Bf-109?
@@HistoricAeroEngines Not an official reference, from someone during the war in the UK that was sent out to inspect German V12 engines. Its no secret that during the war, the Allies used many german patents and even paid for their use after the war.
Certainly, both sides analysed all crashed aeroplanes in detail. Avionics, radar, radio direction finding, beams, jamming, as well as airframe and engine details. Used to determine performance limitations, strategic weaknesses which could be exploited in combat. However, you cited that Rolls-Royce copied the Bf-109 main or conrod caps. The engine designs differ significantly in these areas.
@@HistoricAeroEngines my source told me, its not the caps, its the fastener hardware that was changed very slightly, its probably difficult to detect the change that was made.
It is true that the conrod bolts did evolve. The Merlin received more than 4,000 modifications to improve the overall design and reliability. Regarding the conrod bolts, A.C. Lovesey (Merlin Development Manager, 1940 onwards) wrote that extensive photo-elastic tests were carried out on the bolts fitment and stress concentrations identified. Radiusing the fitment, polishing the bolt finish, and blending the bolt and the rod lug were the areas of change.
What is the launch RPM ?
For a second, I pictured him yanking on a spring loaded pull starter 😂
Land Rover back door was hanging for hear life
How did you stop it from flying away?
I feel sorry for the lawn😢
Выполняя работу с таким монстром , мог бы и ложемент- подставку под блок изготовить , чтобы не упираться такой массой на шпильки блока......
A Mark XX would be a USA built Packard product. Mark IIX and beyond were 90%+ Packard built. Only Packard built Merlins would last more than 4 take-offs and 50 hours in a British "Heavy Bomber". The short flight-time of Merlins in Spitfires led to the creation of the "Griffin" and not-used sleeve-valve Rolls-Royce "Mistal" engines. RR named their areo engines after Birds of Prey, then after "Wizards".
Thanks for commenting, but there are a few misunderstandings. - Merlin XX engines were only produced by Rolls-Royce at UK plants; the first XX was manufactured on 4th July 1940. In August 1940 Packard received the drawings of the Merlin XX for basing their engine production on. Packard's first Merlin was the V1650-1 (UK designated the Merlin 28) and ran in August 1941, with the first production engine running in early October 1941. - I do not understand what a "Mark IIX and beyond were 90%+ Packard built" means. Of all the Merlin engine manufactured, 31 percent were built by Packard. - Regarding 4 takeoffs and 50 hours, I do not recognise this information. Merlin XX first maintenance is 50 hours and major maintenance at 250 hours. The attrition loss rate meant many engines never received major maintenance. (Early Lancasters suffered 50% loss rates). - The Griffon (sp 'Griffin') has no relation to the Merlin, with entirely different heritage. The Griffon was a more powerful engine and was required at a time when the late mark Spitfires were 50% heavier than the original, 100mph faster and carried more fuel and cannons. - RR aero piston engines were usually names after birds of prey. (RR jet engines named after rivers).
British engineering, ingenuity, courage and spirit is one short video, wonderful. I thought this was an election campaign video by Nigel Farage, 😂 if you love Great Britain vote REFORM!
Used for transport command it says in your description (after it was upgraded)......It's so very complicated to see how the military makes all these decisions and upgrades and planning for engines and how they are deployed, updated, switched out, etc etc. Who in the military (RAF) was making all of the tedious decisions like this? It would seem that there must have been hundreds and hundreds of advisors, manufacturers, planners, estimators, logistics, managers, captains, generals and other various higher-ups making a lot of these very complicated decisions regarding War-Planes in WWII. It's all just mind-blowing. If you know a little about how all of that unfolded during war-time, please do tell.
With regard to aero engines, their production and maintenance records were retained throughout WW2 and their service life until they were scrapped. It tracked their level of maintenance, technical upgrades and improvements. Undoubtedly, there would have been many administrators tracking all this information. This is far from being tedious; aircraft safety requires significant record keeping back then and is still the case today. For this engine, the production history, upgrade dates, types and location of the work are known. However, which specific aircraft this engine was used on was not kept. You can read a little about the RAF record archives at: www.rafmuseum.org.uk/research/default/archive-collection/aircraft-records/
what did the neighbors say about the noise?
Check the description for details.
Sounds like a well sorted Engine .
Noticed the same. I don't recall a Merlin starting so 'easily' and running so smoothly right off throttle. I think David-Dave have raised the bar.
This Merlin is one of our regular display engines, and is, probably, started more often than most flying Merlins during a display day.
Thanks for some very nice videos... Amazing engines you are working with..Amazing Engineering back then. Do you know where to get main bearings for the metheor or Merlin?.... Best regards team gators tracktorpulling Denmark👍
OMG!!! Where is his hi-viz, hard hat and goggles? .... Oh .... and clip-board?
I once worked at White Waltham airfield many years ago in one of the old WW2 hangers there. I was told by more that one person that there were several Merlins mothballed in a room under the ground but they had been sealed up. How much truth is in that I don't know, but it's an interesting point. Most of those things were handed down like that had a lot of truth to them.
Mounting, intake, and radiator from a Lanc? Beau QEC?
Bearers are Avro Lincoln; stronger that Lancaster bearers, for UK roads! Air inlet cowling is Lancaster. Serck radiator design.
@@HistoricAeroEngines Thanks.
That thing sounds like a 1500 horsepower sewing machine. Only the DB601 sounds better lol
If you like coffee grinders ;)
This is the very sound of resistance. A timely reminder.
