The Ivchenko AI-14 (Russian АИ-14) is a nine-cylinder, air-cooled, radial piston engine designed in the Soviet Union to power aircraft.
Its main variant is the AI-14R (АИ-14Р), which underwent state trials in December 1950 and was used in many types of light aircraft. Several thousand were built. There was also an AI-14V variant for helicopters and other applications. The AI-14R is typically used with a two-bladed propeller and is started with compressed air.
Apart from the Soviet Union, a licenced version of the AI-14R, (including the AI-14RA), has been produced by WSK-Kalisz in Poland from 1956 until 2007.
The AI-14RF was a variant uprated by Ivan Vedeneyev to 300 hp. Its further development is the Vedeneyev M14P family of engines.
Another modified version is the Czechoslovak Avia M462, which powers the Zlín Z 37 agricultural aircraft.
The Zhuzhou HS-6 was the designation for AI-14 Licence production in China.
