Formed basis for the Rolls-Royce/Rover Meteor tank engine "Racing" Merlin; Racing engine for 1937/38 "Speed Spitfire" world speed record attempt. Merlin III with strengthened pistons, connecting rods, and gudgeon-pins, running on increased octane fuel, developed 2,160 hp (1,610 kW) at 3,200 rpm and +27 lb boost, a power/weight ratio of 0.621 lb ...
The Merlin 1B rocket engine was an upgraded version of the Merlin 1A engine. The turbopump upgrades were handled by Barber-Nichols, Inc. for SpaceX. [ 10 ] It was intended for Falcon 1 launch vehicles, capable of producing 380 kN (85,000 lbf) of thrust at sea level and 420 kN (95,000 lbf) in vacuum, and performing with a specific impulse of 261 ...
Rolls-Royce Merlin 23. This is a list of Rolls-Royce Merlin variants. Engines of a similar power output were typically assigned different model numbers based on supercharger or propeller gear ratios, differences in cooling system or carburettors, engine block construction, starting system, or arrangement of engine controls.

Merlin 1 is a family of LOX/RP-1 rocket engines developed 2003–2012. Merlin 1A and Merlin 1B utilized an ablatively-cooled carbon-fiber composite nozzle. Merlin 1A produced 340 kilonewtons (76,000 lb f) of thrust and was used to power the first stage of the first two Falcon 1 flights in 2006 and 2007.
The first American model was a version of the Mark XX, designated the V-1650-1 by the American military and the Packard Merlin 28 by the British. This engine used a single-stage, two-speed supercharger, the gear changing mechanism of which originally came from a French Farman patent license. The Merlin 28 was used for the Avro Lancaster bomber
The initial production P-82B had Merlin engines, but North American was forced to use the Allison V-1710 for the E/F/G models when Rolls Royce required a "Royalty" of $6,500.00 per engine and the U. S. Government stopped buying the Merlin engine because of the excessive cost.
Although construction of the Henley prototype began in mid-1935, the Hurricane had priority, and it was not until 10 March 1937, powered by a Merlin "F" engine, that it first flew at Brooklands, shortly after the competing Fairey P.4/34. Subsequently, the aircraft was refitted with light alloy stressed-skin wings and a Merlin I engine (the ...
