AI-222-25F Turbofan Engine With Afterburner

The AI-222-25F afterburning version of the AI-222-25 turbofan engine featuring a thrust at takeoff of 42000kgf (thrust reheat ratio is 1.68) is designed to power trainers, advanced trainers and light combat aircraft with minimum flight speed of M 1.5. The engine has been optimized to be operated on uptodate trainer, combat trainer, and light combat aircraft and complies with strict requirements for the engines of this class. The turbine compressor section of the engine is fully unified with that of the AI-222-25 basic engine.
