Klimov VK-1

The Klimov VK-1 is a Soviet turbojet engine, beginning production late in World War II. It was developed by Vladimir Yakovlevich Klimov and first produced by the GAZ 116 works since 1945. Its design is derived from the British Rolls-Royce Nene, whose development was closely followed by a large number of Soviet spies within Britain's defence industry. The VK-1 was used to power the Mikoyan-Gurevich MiG-15 (Fagot) and Mikoyan-Gurevich MiG-17 (Fresco) fighters, as well as the Il-28 bomber. The engine featured a centrifugal compressor, requiring a larger-diameter fuselage than aircraft featuring axial compressor designs. It had a maximum thrust of 26.5kN, though the later VK-1F model added an afterburner with which it could reach 33.8kN.
