The United Engine Corporation (UEC) of Rostec presented a model of the promising SM-100 engine for the upgraded Yak-130M combat training aircraft at the Army-2023 international military-technical forum. About it reported in the company’s Telegram channel.
SM-100 is a development of the AI-222-25 base engine. The new engine will have improved performance with similar dimensions and weight, for example, the maximum thrust will increase by 20%, and the resource will double. The creators of the engine achieved this by increasing the compression ratio, installing a modern three-stage low-pressure compressor, introducing upgraded combustion chamber components and a turbine of increased reliability.
Now the low-pressure compressor and turbine are undergoing bench tests, and the combustion chamber is undergoing flight tests. The upgraded high-pressure compressor is also being prepared for testing, now smaller, lighter and cheaper to manufacture. Especially for the upgraded engine, a reinforced gearbox was created. It allows you to install a drive-generator, the rated power of which is twice as high as that of the basic version of the engine.
At the Army-2023 forum, Rostec First Deputy General Director Vladimir Artyakov said that the state corporation intends to multiply the production of Lancet kamikaze drones. “Lancets” are widely used by the Russian Armed Forces as part of a special operation in Ukraine. The Ministry of Defense regularly reports on the destruction of enemy equipment by such drones.
