the V12 (engine2) is a Meteor, again like the Merlin a 27 litre V12.
the Meteor and Merlin are related. the diffence between the Merlin and the Meteor is a lack of supercharger and it has a clutch take off like a car on its fly wheel for the transmission in a tank where the Merlin has a reduction gearbox to allow it to drive an aircraft propeller. apart from that, there i think is virtually NO difference.
The Meteor engine has heavier internals and other components. They aren't interchangeable with the aero engines, but there are common parts. Reject parts from Merlin assembly lines found their way into the Meteor engines as well. Today, I believe some Meteor engines are getting converted for aero use with correct modifications from the few engine shops that do Merlins.
Weren't these engines also used in the Lancaster MKII's ? due to a concern that there wouldn't be enough Merlins produced for the Spitfires and Hurricanes, I know they used a radial engine in the MKII's just not sure which one it was.
Those are nice stoves.Neat how you can see the firing sequence in the exhaust on the V-12.When the neighbour fires up his annoying little leaf blower you roll that big beauty out and show him yours.Speaking of neighbours......they must get along quite well with each other cause that's a tick or two louder than a lawnmower or a barking dog.
Sounds amazing, absolutely amazing. I just watched an animated computer thing of how a sleeve-valve engine works. Fascinating. It seems to me it would be more reliable than an engine with "normal" valves (seems like fewer moving parts/not as complex). How did these compare in reliability with say, a Pratt & Whitney, or some other non-sleev- valved-engine? Thanks.
If you mean put some sort of guard on it, that would be too dangerous for both the engine and the people around it. If the guard fails, the prop is going to chew it up and fling bits around like bullets; sticking deep in anything the shrapnel hits.
The prop would also likely get destroyed, causing damage to the engine as well.
the Herc was used in a small sting of B-111 Lancaster bombers, used in very high altitude flights. Ive never actually seen a demo of this engine till now. The meteor is close to the Merlin in build just naturally asperated. The Merlin was the other engine option to the Lanc. Great video and great display models.
"Rover Meteor V12 used in Brit tanks from 1945. Last use was in Centurion tanks as the Mark 4B version."
1942, 1944 in volume production. The US would not use it despite Packard making RR Merlins under license in the USA. It was far superior to anything the US had.
i have an airboat with a three fifty chevy in it three hundred horse and it pushes my trailer im surprised that doesnt push his trailer thats an awesome engine would be neat to see it in an airboat wow nice video
Last of them, a bit improved, are built under license by SNECMA in France and use on the Nord 2501 Noratlas twin engine military transport aircraft: i fly with, and love the vonderfull noise and blue flames from the exaust in the night...
No the Seafury used the Bristol Centaurus. The Hercules of various models was used in the Bristol Freighter, Handley Page Hastings post war(to name a few) and was used in the Mark II Avro Lancaster, Bristol Beaufighter, Handley Page Halifax and so on in World War 2.
Felicitaciones a los mecanicos!! me erizo´ Que Motor ! Nunca habia visto funcionar un motor tipo Knight Me ncanto la prueva del rool royce Musica para mis oidos
Yes and in flyght it's realy beautyfull: fly in a Noratlas witch use 2 Bristol Hercules (engines built under license in France by Snecma): this engine is very relable, 30% more TBO time and smaller diameter for the same power as conventional radial engines, burn 15% less gas for the same power (in the night whe see the blue flames at the exausts), realy nice engines , for me the best aircraft piston engine ever built (sorry Merlin...)
The Bristol Herc is a sliding cylinder 2-stroke. Correct, a high power/weight ratio and smooth having no valves. However, it had a lot of gearwheels to move the sleeves up and down. Fitted in the Bristol Beaufighter in WW2, the Japanese called it "whispering death" when fitted with appropriate exhaust. The first time they would hear it, it would dropping bombs or strafing them.
Mainly fitted in heavy planes like bombers and cargo planes.
No, the Bristol sleeve valve engines are NOT 2 strokes, but 4 stokes : i think you dont' understand correctly the technology from this engine: i Know it good but i'm was aircraft mecanic 30 years ago...
4-stroke? OK. Most of this type were two strokes. Now the RR Crecy of similar type and 2-stoke was a hell of an engine. A pity it never made it into a plane, or tank or whatever.
The 2 stroke engines are never use on aircraft (only on ultralights) except as Diesel: high power diesel engines are common 2 strokes (see the giant ship engines: Wätzilä 14 cylinder up to 130 000hp at 102rpm...), but this engines use valves for exhaust and holes for intake (compressed air only), pneumatic injection...
The power to weight from a diesel 2 strokes are near the same as from a gasoline engine...
Thanks. The power to weight ratio of the Rootes TS3 opposed piston, one crankshaft (the Juno had two), diesel engine was far greater than the eqiv HP of a gasoline engine at the time.
Cosworth made a prototype sleeve engine with highly encouraging results.
Sleeve valve engine I am sure is dead, despite promise. Current engineering gives high tolerances. Electric motor traction and a small range extender engine now is the way - Lotus do a good one. Very small Wankels are ideal
@NearAbbeyRoad Even though manufacturing processes today allow for tighter tolerances, the unusual wear pattern of a sleeve rotating side to side and moving up and down will eventually cause the engine to burn and leak oil. Not to mention the added complexity inside the engine to drive the sleeves raises costs and introduces more points of failure in the engine.
2-stroke in-line sleeve can be very reliable and last using high tolerances and superior materials. The sleeve need not rotate. The mechanism to move the sleeve is less complex than camshafts and valves - an engine with greater power-weight and very smooth. I doubt if it will be seriously taken up again.
Ecomotors 2-stroke OPOC, Bill Gates $, looks like will make the market. Smooth, can have two coupled by an electric clutch using one engine on low loads - 2nd engine has NO drag
The RR Meteor was the best tank engine of WW2. Before the Meteor all Allied tank engines were poor. It was made by Rover until 1964. Many are still in tanks today.
I love round motors and there is nothing that can beat the sound of a big radial.
I have a friend who owns a Harvard T-6 with a P&W 1340 and a T-28B with a with a Wright Cyclone. These engines sound quite different from one another.
There is a man in California USA, Elsworth Getchel by name, who owns a Hawker Sea Furry which still has the original Bristol Centurion engine. He makes the air show circuit here in the US. Wonderfull engine and wonderfull aircraft.
You are right about the sound, they sound like a BIG block V8. My favorite is the centuarus. I was not aware of lubrication issues on the later engines, I have always understood they were very dependable, the centuarus in particular. As far as synthetic oil, mobil pulled it's synthetic AV oil off the market years ago,there were engine failures because the oil could keep lead particles in suspension and was never certified for use in radials.
Castor oil would only work in total loss oil systems (IE. Clerget 9c, gnome, other rotaries.) In an engine of this size, it would quickly break down from the heat and friction. In cold weather it would clump together and make starting the engine hard or impossible.
The Rolls Royce Meteor was a tank engine used it the Centurian. Rolls Royce sold their piston engine business to Rover and took over their gas turbine business. (Shame Rover made such lame duck cars until the Germans took it over). The Meteor was a cxast iron based Merlin minus the superchargers.
The sleeve valves make it sound so much different than one with pushrods. One of the most unique radials ever made, even though they tend to consume a ton of oil (even by radial standards.)
Sounds so smooth! I'd love to see 4 of them running on an old Stirling
