Russia's United Engine Corporation (UEC), a subsidiary of Rostec, is making a significant debut at Airshow China by showcasing its latest fifth-generation engine for operational-tactical aviation to the international community.
This marks the first time the engine has been publicly displayed outside of Russia. Alongside this cutting-edge technology, UEC is also presenting an upgraded line of its widely recognized AL-31F/FN engine family and the new SM-100 engine.
The AL-31F/FN engine family has powered a variety of fighter jets and remains a crucial part of UEC's portfolio. Notably, the AL-31FN variant, originally developed for the Chengdu J-10, boasts increased thrust capabilities reaching 12.7 tonnes-force. This variant features a redesigned gearbox configuration, optimized for the J-10 platform. Further upgrades to the AL-31FN series, such as the Series 3 variant, have elevated its thrust output to an impressive 13.7 tonnes-force.
India's Su-30MKI, a key multirole fighter in the IAF fleet, utilizes the AL-31FP variant, produced both in Russia and in India under a technology transfer agreement with Hindustan Aeronautics Limited (HAL). While maintaining the 12.5 tonnes-force thrust of the base AL-31F, the AL-31FP incorporates thrust vectoring technology, enabling nozzle deflection up to ±15° at a rate of 30°/sec. This capability significantly enhances the Su-30MKI's maneuverability and combat agility.
UEC's unveiling of its fifth-generation engine and updated engine lineup comes at a time when India is actively seeking advanced propulsion systems for its indigenous aircraft programs. The IAF's focus on developing supersonic trainers and combat aircraft, such as the HLFT-42, creates a potential opportunity for UEC. The HLFT-42, a supersonic trainer under consideration, would require high-performance engines with features like thrust vectoring and improved fuel efficiency. UEC's fifth-generation engine could potentially serve as a benchmark or even a contender for this program.
