Russian-French SaM146 engine surpasses 600,000 flight hours

The Safran- and UEC-produced Russian-French SaM146 engine that powers Sukhoi Superjet 100 (SSJ100) airliners has logged over 620 thousand flight hours in operation, the companies said.

The SaM146 engine, produced within the 50/50 partnership between Safran and UEC, is successfully operated all around the world by well-known airlines such Russian Aeroflot, Mexican Interjet and Irish CityJet.

SaM146 is an integrated power plant which includes the engine and the nacelle equipped by a thrust reverser.

The deliveries of SaM146 and all the after-sales services are performed by PowerJet, a joint venture formed on the principles of equal representation by Safran Aircraft Engines and Russian UEC-Saturn (a part of the United Engine Corporation, UEC).

UEC-Saturn is a developer and producer of the fan, the low-pressure compressor and the low-pressure turbine, and is also responsible for the final engine assembly and its testing. Safran Aircraft Engines is a developer and producer of the high-pressure compressor, the combustion chamber, the high-pressure turbine, the gearbox, the FADEC system.

The French company also performs the overall integration of the power plant and is responsible for the final engine assembly and ground tests.

The engine of Yakutia Airline has reached 7,800 flight hours; the Interjet engine has surpassed 6,400 flight cycles.

SaM146-powered SSJ100 are currently used by 15 operators.
