AI-25TL, AI-25TLK
The AI-25TL engine is intended for L-39, the AI-25TLK engine is intended for K-8J aircraft and other trainers. It is successfully operated worldwide.
The engine is an AI-25 turbofan follow-on. As compared with the base engine, the AI-25TL (AI-25TLK) engine is distinguished by a higher compressor pressure ratio and higher turbine inlet temperature, all that allowing to increase the engine thrust.
The engine is equipped with a special lubrication system to enable normal operation under zero-g and negative-g conditions. |

Main advantages of the engine:
- High reliability and trouble-free operation;
- Longer service life as compared with other similar engines;
- High maintainability;
- Potential to further increase the engine performances after insignificant design changes.
