SaM146 engine for regional jets


SaM146 - The standard for regional aviation

Designed, produced and marketed by PowerJet, the SaM146 integrated propulsion system powers the Sukhoi Superjet 100 regional jet, or SSJ100.

An optimized integrated propulsion system, comprising the engine and its accessories, plus the nacelle.* *Supplied by Safran Nacelles.

Its architecture is derived from the CFM56 turbofan from CFM International*, the best-selling engine in commercial aviation history. *50/50 joint company between Safran Aircraft Engines and GE.

A complete package of dedicated services.

A French-Russian partnership

The SaM146 is developed by PowerJet, a 50/50 joint company between Safran Aircraft Engines and Russian engine-maker UEC Saturn. Safran Aircraft Engines is responsible for the overall design and certification of all versions of the SaM146, the development and production of the engine core, control systems and power transmission, system integration and flight testing.


Proven technologies

Its architecture is derived from the industry-leading CFM56 turbofan, meaning that the SaM146 benefits from Safran Aircraft Engines’ top technologies, in particular 3D aerodynamic design. Because of these advanced technologies, coupled with fewer stages, the SaM146 offers significant advantages* in terms of fuel consumption, environmental footprint and maintenance. *Compared to other current engines in its thrust class.
