Bristol Mercury Engine

3D Printed Resin

Bristol Mercury is a British aircraft engine from the interwar period and the Second World War. The engine was first successfully introduced in 1925 and mass production began shortly afterwards, resulting in the production of over 20,000 of all versions of this engine. The length of this power source (in the Mercury VI-S version) was approximately 120 cm, with a diameter of 130.7 cm. The weight of the "dry" power source of this type was 438 kilograms. The unit presented was an air-cooled 9-cylinder radial engine, capable of generating a maximum power of 635 hp. It is worth adding that the entity responsible for production was the Bristol Airplane Company, and the engine itself was constantly developed in the 1920s, 1930s and 1940s, and the differences in maximum power between the versions were significant. For example, the 1928 Bristol Mercury II produced 420 hp, but the 1935 Mercury VIII model - 825-840 hp! This successful and modernizable engine, which, by the way, became the basis for the development of the Bristol Pegasus engine, was installed on many aircraft, including: Bristol Blenheim, Hawker Hart, Hawker Fury, Gloster Gladiator, Westland Lysander, but also PZL P.11 and Fokker G1 and D21
