Ivchenko-Progress AI-222
Turbofan aircraft engine
The Ivchenko-Progress AI-222 (Ukrainian: AI-222, Russian: АИ-222-25) is a family of low-bypass turbofan engines.
01Design and development
The development of the engine started at Ivchenko-Progress of Zaporizhzhia, Ukraine in 1999. The engine was originally intended for the Yakovlev Yak-130 trainer aircraft. An afterburning version, the AI-222-25F (from Russian/Ukrainian term "Форсаж") is also available with thrust vectoring.
In 2015, Russian manufacturer "Saljut" began to produce AI-222-25 without any Ukrainian involvement.
