The British
Rolls-Royce Merlin was a liquid-cooled two-stage
supercharged aircraft engine with 12 cylinders and a
displacement of 1649 cubic inches (27.0 liters.) Total weight was 1690
lbs (767 kg) and maximum rotations per minute was 3000. Its
supercharger was superior to that in the V-1710 Allison, giving it much
better high altitude performance.
The Packard-Merlin V-1650 was
a version produced under license in the United States by Packard using
American methods of mass production. Full production began in 1942 and
55,511 engines were produced.
Individual cost was about $25,000.
