The SaM146 engines produced by PJSC "UEC-Saturn" (a part of United Engine Corporation (JSC), a Rostec State Corporation company) in cooperation with French Safran Aircraft Engines operated more than 300 000 hours as a PPS part at Aeroflot's Sukhoi Superjet 100 (SSJ100).
SaM146 is an integrated PPS including an engine and a nacelle with a reverser unit.  SaM146 deliveries and all after sales support services are managed by PowerJet (a joint venture based on the principles of equal partnership between Safran Aircraft Engines and "UEC-Saturn").  "UEC-Saturn" (Rybinsk) is responsible for the development and production of the fan and low pressure compressor (LPC), low pressure turbine (LPT), SaM146 engine assembly and tests; Safran Aircraft Engines is in charge of the high pressure compressor (HPC), combustion chamber, high pressure turbine (HPT), accessory gear box, engine control unit and PPS integration. The SaM146 engine as well its production is certified in compliance with EASA and IAC AR regulations.

SSJ100 commercial operation in Aeroflot started in 2011. PowerJet renders comprehensive support to the Airline by ensuring the most efficient SaM146 engine operation.

The total operating time of SaM146 PPS in service exceeds 800 000 hours.  As of today, more than 300 engines have been delivered.  However, the year of 2017 was considered to be the record one since Customers received 76 SaM146 PPS.

The first production SaM146 engine was shipped in 2010 and its commercial operation as a part of the SSJ100 aircraft started in 2011.  Today, the SaM146 PPS boosts into the air the aircraft of 15 Russian Airlines (Aeroflot, Yakutia, Yamal, IrAero, Gaspromavia, Azimut and other Operators) as well as in other countries, such as Mexico, Ireland, Thailand (the Royal Air Forces) and Kazakhstan.

The two-shaft turbofan SaM146 engine combines the experience and new technologies of Russian and Western engine-building and it fully meets up-to-date environmental requirements.  The optimized by-pass level and fan’s reduced rotation speed allowed to significantly reduce the noise caused by engine operation and ensure margin with regard to ICAO part IV regulations.  The combustion chamber is designed to ensure low pollutant emission level and compliance with CAEP8 regulations. Engine control system is digital with full authority (FADEC type). SaM146 engine has a wide thrust regulation range.

Today, there are four certified versions of the SaM146 engine: 1S17 - the basic version, 1S18 - with the increased thrust, and 1S17С and 1S18С for the business jet".

The engine design allows rendering flexible after-sales services.  There is an easy access to the engine and it can be quickly removed from the wing.  The SaM146 engine has a modular design, and when the concept of the operation depending on engine's health is applied, there is no need to disassemble the engine in full during shop visits if it is required to replace the parts or repair one of the modules.

Two SaM146 spare parts distribution centers have been built in Lytkarino located near Moscow and in French Villaroche in order to create a Customer support system complying with the world standards.  Such localization of warehouses allows delivering spares to any part of the world within 24 hours. Two training centers are available in Russia and France for training of airlines' engineering staff and two repair shops for timely maintenance and shop visits. Round-the-clock Customer support center and a web-portal were established.
