Ivchenko AI-14
From Wikipedia, the free encyclopedia
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 a variant AI-14V for helicopters and other variants. The AI-14R is typically used with two-blade propeller and is started with compressed air.
Apart from the Soviet Union, licenced version of AI-14R, currently AI-14RA, is produced by WSK-Kalisz in Poland from 1956 until now (as of 2007).
The AI-14RF was a variant uprated by Ivan Vedeneyev to 300 hp. Its development is Vedeneyev M14P family of engines.
