Hispano-Suiza 12Y

The Hispano- Suiza 12 are water-cooled aircraft engines of the Spanish- Swiss manufacturer Hispano -Suiza. The twelve-cylinder gasoline engines came primarily in the 1920s and 1930s in French production machinery used.

The type HS 12Y was produced from 1934 in the Soviet Union as a Klimov M-100 under license.

History

The existing eight-cylinder V-engine Hispano -Suiza 8 ( HS 8 ) could not ensure the desired higher engine performance. Based on the British Napier Lion, a Y- engine with three banks of cylinders, hence the Hispano- chief designer Marc Birkigt began in 1919 with the development of a twelve-cylinder Y motor. As in the HS-8 - types cylinder banks were cast in one piece from an aluminum alloy and is provided with screwed-in liners. The crankcase was split horizontally. Each of the three cylinder banks had a single overhead camshaft with vertical shaft drive. The valves (two per cylinder) were directly operated by the camshaft via tappets. The configured with an output of 400 hp ( 294 kW) Hispano- Suiza new 12G was completed in 1920 as a prototype; to 1925 300 piece version of the HS were produced 12Gb.

Because of the elaborate production of this Y- engine developed Birkigt a simpler V- engine which came with identical data from bore and stroke the mid-1920s as HS 12H into production.

Subsequently the constantly improved. 1932 appeared the HS 12Y, as the major difference to its predecessor HS 12X had a crank mechanism of main and Anlenkpleuel. From the design HS 12Ycrs to all Hispano- V -12 types were provided with a hollow propeller drive shaft; so that a 20 -mm automatic cannon HS 404 could be mounted between the cylinder banks; an arrangement which was referred to as moteur Canon. The model HS 12Y reached the highest numbers - the version made ​​from 1938 12Y -51 with compressor had an output of 1,100 hp ( 809 kW). With four valves per cylinder and fuel injection came in 1940 for a short period of HS 12Z -17 ( power 1500 kW PS/1103 in 6400 meters above sea level ) in the manufacturing process. After the Armistice of Compiègne in June 1940, first production ended in the French Hispano- work Bois -Colombes. After the Second World War Hispano presented as the latest version produces the HS 12Z -89.
