Ukrainian afterburning turbofan engine

The Ivchenko-Progress AI-322 (Ukrainian: AI-322, Russian: АИ-322) are a family of low-bypass turbofan engines developed from the AI-222 engine.

Design and development

The development of the engine continues at Ivchenko-Progress of Zaporizhzhia, Ukraine. The engine was originally intended for the Hongdu L-15 trainer aircraft and it is now planned to be used in Baykar Bayraktar Kızılelma fighter UAV. An afterburning version, the AI-322F is also available.
