Russian jet engine manufacturer, Salut has successfully completed testing of the fully indigenised version of the Ivchenko Progress AI-225-25 low bypass turbofan engine, which powers the Yakovlev Yak-130 combat trainer aircraft.
The Ukrainian components, which earlier consisted half of the engine has been completely replaced by Russian made parts, following suspension of military and diplomatic relations between the two countries due to the Crimean crisis.
The localized engine demonstrated improved reliability and extended service life, during ground testing carried out on the first indigenous engine manufactured by Salyut.
Service life and mean time before overhaul (MTBO) of Salyut manufactured AI-225-25 engines have now more than doubled. The MTBO increased to 1,500 flight hours from the earlier 600 hours and service life increased to 3,000 hours from 1,200 hours.
Localisation of the engine was completed in 2015, and is currently being produced at Salyut's Moscow factory. Company has already supplied the engine to Russian armed forces and is also providing comprehensive after sale support services.
Since introduction into Russian service in 2012, more than 80 Yak-140 trainers have been delivered by Irkut Corporation. The Yak-140 and the Italian Leonardo Alenia M-346 trainer jets shares the same platform, although with different engines and avionics.
The Yak-140 is powered by two AI-225-25 engines rated at 24.5 kN thrust each. The engine features a two-stage axial low-pressure compressor, an eight stage high-pressure compressor, an annular single-stage combustion chamber, a single-stage cooled turbine of high and uncooled low-pressure turbine.
The FADEC controlled engine with a bypass ratio of 1.18 has a compressor ratio of 15.4 and weights 440 kg when dry.
