UEC SM-100
United Engine Corporation's SM-100 is a turbofan demonstrator in the AI-222-25 size class for trainer/combat-trainer aircraft and potential high-altitude UAV applications. UEC states that it is lighter than the AI-222-25 and provides up to 3300 kgf of thrust (stored here as 32.36 kN, converted from kgf); operation at reduced thrust is intended to enable longer service life. It remains a development-stage demonstrator/mockup, with no production service or aircraft installation asserted here.
