Basic aircraft engine of Soviet fighters of world war II.
In the first half of the 1930s, Soviet Union bought a licence for French Hispano-Suiza engines. Taking advantage of thus obtained foreign technological solutions, Vladimir Klimov with his construction bureau designed a series of powerplants. Among them was the WK-105 PF2. Alexander Yakovlev's construction bureau, developing fighter aircraft for which the powerplants were intended, co-operated with Klimov. The engine was developed further, however performance was increased at the expense of the engine's life span. Despite that, the WK-105 in different variants was one of the most popular aircraft engines manufactured in Soviet Union.
The VK-105 engine is fitted with six carburettors – one per every two cylinders and a two speed supercharger. A cannon, firing through the propeller shaft could be placed between the cylinder rows. The engine was used on the Yakovlev's and Lavochkin's fighters and on the Petlyakov's Pe-2 dive bomber.
