Ivchenko-Progress AI-222

The Ivchenko-Progress AI-222 (Ukrainian: AI-222) are a family of low-bypass turbofan engines.

Contents

Design and development

The development of the engine started at Ivchenko-Progress of Zaporizhia, Ukraine in 1999. The engine was originally intended for the Yakovlev Yak-130 trainer aircraft. An after-burning version, the AI-222-25F (from Russian/Ukrainian "Форсаж", meaning reheat) is also available with thrust vectoring. In 2015 Russian manufactor "Salut" began to produce AI-222-25 without any Ukrainian involvement.
