A Spanish-built version of the Messerschmitt Bf 109 G-2, the 1954 Hispano Aviación HA-1112-M1L Buchon, was built in Hispano's factory in Seville with the Rolls-Royce Merlin 500/45 engine of 1,600 horsepower (1,200 kW) – a fitting powerplant for the last-produced version of the famous Messerschmitt fighter, as the Bf 109 V1 prototype aircraft ...
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.
Depending on the supercharger fitted, engines were rated as low altitude (e.g.; Merlin 66, Griffon III), where the engine produced its maximum power below about 10,000 feet (3,000 m), medium altitude (Merlin 45), where the engine produced its maximum power up to about 20,000 feet (6,100 m), and high altitude (Merlin 70), where the engine produced its maximum power above about 25,000 feet ...
A preserved Rolls-Royce Griffon 58, one of the last Rolls-Royce piston engines to be produced. The red and white "dumb bell" object to the left of the engine is an air raid siren exhibit Rolls-Royce produced a range of piston engine types for aircraft use in the first half of the 20th century.
In the early months of 1942, with the clear superiority of the Focke-Wulf Fw 190 over the Spitfire Mk Vb, there was much pressure to get Spitfires into production using the new two-stage supercharged Merlin 61 engine. In September 1941 the Spitfire Mk III prototype N3297 had been converted by Rolls-Royce at their Hucknall plant to take a Merlin ...
The first Griffon-powered Spitfires suffered from poor high altitude performance due to having only a single stage supercharged engine. By 1943, Rolls-Royce engineers had developed a new Griffon engine, the 61 series, with a two-stage supercharger. In the end it was a slightly modified engine, the 65 series, which was used in the Mk XIV.
Bentley Motors Limited is the direct successor of Rolls-Royce Motors and its predecessor entities and owns historical Rolls-Royce assets such as the Crewe factory, pre-2003 vehicle designs and the L Series V8 engine. Rolls-Royce Motor Cars, a subsidiary of BMW AG established in 1998 that began production of vehicles in 2003.
The Rolls-Royce Merlin engine originally came with a direct carburettor, prone to cut-out due to fuel flooding in negative G. Miss Shilling's orifice was a very simple technical device created to counter engine cut-outs experienced during negative G manoeuvres in early Spitfire and Hurricane fighter aeroplanes during the Battle of Britain.
