Why The Name "Merlin" Was Chosen?
It all started with R.J.Mitchell who was determined to see that Britain had an all-metal, powerful fighter plane to combat anything the Axis would send against them. Even though he was facing all manner of different obstacles, including the fact he was dying of a terminal illness. He pushed through and made the 'V-12 Merlin Engine' and saw its first successful flight before passing away in late 1930's. His hard work and determination pushed the boundaries of engineering and the way we designed engines.
At Merlin we use the same ingenuity and passion for improvement as R.J.Mitchell. This is due to the fact that we constantly seek for improvements on all that we design, build and manufacture.
Interesting History About The Merlin Engine?
The Rolls-Royce Merlin V-12 is almost certainly the most famous aircraft engine in history. It’s named after the Merlin bird of prey (Falco Columbarius), a species of falcon that’s been a popular falconry bird for centuries.
The Rolls-Royce Merlin is a 27 liter (1,650 cu. in.) V-12 with an aluminum alloy crankcase, aluminum alloy cylinder blocks with high-carbon wet steel liners, and aluminum alloy heads.
Phosphor bronze was used for the exhaust valve guides with cast-iron used for the inlet guides, four valves are used for each cylinder – two inlet and two exhaust. The inlet valves are steel with “stellited” ends as are the exhaust valves, though the exhaust valves also have sodium-cooled stems.
Each camshaft operates 24 rockers, with 12 on each side and each valve has twin concentric coil-springs. The 12 pistons are lightweight alloy, each is uses a forged nickel-steel connecting rod, which is attached to a forged nitrogen-hardened nickel-chrome molybdenum steel crankshaft.
Initially the Merlin produced approximately 1,000 hp, but by the end of the war this number had over doubled, and Merlins were reliably producing well over 2,000 hp.
Which Planes Were the Merlin Engines Used In?
The legendary Rolls-Royce Merlin engine powered numerous aircraft used by the RAF during World War Two. This was used in forty aircraft during World War Two but it is primarily associated with the Supermarine Spitfire, Hurricane Hurricane, Avro Lancaster bomber and the de Havilland Mosquito. The Merlin was also used to upgrade the power of the previously underpowered P51 Mustang used by the USAAF.
