The engine is an AI-25 turbofan follow-on. As compared the base engine, the AI-25TL (AI-25TLK) engine is distinguished by a higher compressor pressure ratio and higher turbine inlet temperature, all that increasing 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 other similar engines;
- high maintainability;
- potential to further increase the engine performances after insignificant design changes.
