Ivchenko-Progress AI-222

The Ivchenko-Progress AI-222 (Ukrainian: AI-222, Russian: АИ-222-25) are a family of low-bypass turbofan engines.

AI-222
Type Turbofan
National origin Ukraine
Manufacturer Ivchenko-Progress (development) / Motor Sich (Ukraine) and FGUP Saljut (Russia) (manufacturing)
First run 2003
Major applications Yakovlev Yak-130
Hongdu L-15
Developed from Progress AI-22

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 manufacturer "Saljut" began to produce AI-222-25 without any Ukrainian involvement.[1]

gollark: I don't really want a "good" phone, just something RPi-level is okay performance wise.
gollark: I may consider at least not entirely avoiding OLED then, but I don't think any other feature I want is particularly available now.
gollark: I've got both. Gestures are annoying.
gollark: I mean, my phone has a *navbar* most of the time, so I imagine that counts.
gollark: It's probably partly determined by use, but someone here mentioned problems with burn in earlier this very day.
