United Engine Corporation has demonstrated future SM-100 engine mockup for Yak-130M upgraded training and combat aircraft for the first time at the Army-2023 forum. The project will continue the development of baseline AI-222-25 engine. The new power unit will feature high performance with the same dimensions and weight, in particular, the maximum thrust grows by 20% and the service life is twice as long.
The power unit is developed by Salyut manufacturing facility of United Engine Corporation.
Performance improvement has been achieved due to increased compression ratio, state-of-the-art three-stage low pressure compressor, introduction of upgraded combustion sections and robust turbine. The low pressure compressor and turbine are currently undergoing bench test, while the combustion chamber is undergoing flight test.
Moreover, an upgraded high pressure compressor will be also tested in the nearest time. This component has become smaller and lighter and has lower manufacturing cost. A heavy-duty gearbox has been also developed for the upgraded engine in order to incorporate a generator drive whose rated power is twice as high as that of AI-222-25 baseline engine version.
