The PowerJet SaM146 is a turbofan engine produced by the PowerJet joint venture (not to be confused with Power Jets) between Snecma (Safran) of France and NPO Saturn of Russia. Developing 68–80 kN (15,000–18,000 lbf) of thrust, the SaM146 is used on the Sukhoi Superjet 100.
Snecma is in charge of the core engine, control system (FADEC), transmissions (accessory gearbox, transfer gearbox), overall engine integration and flight testing. NPO Saturn is responsible for the components in the low pressure section and engine installation on the Sukhoi Superjet 100 regional aircraft and ground testing.
The SaM146 design is based on the CFM56. In keeping with the design and development of jet engines from manufacturers like Pratt & Whitney, General Electric and Rolls Royce, the engine has been conceived to meet customer requirements regarding fuel burn, cost of operation and dispatch reliability.
The core was developed by Snecma, drawing on its M88 ‘hot section’ military engine experience and the DEM21 core demonstrator project – with its six-stage compressor and single-stage, high-pressure turbine with active blade-tip clearance control – and various other modern design features (such as single-piece bladed disks).
The SaM146 provides 62 to 77.8KN of thrust (6,200 to 7,700 kg). In April 2003, Sukhoi Civil Aircraft Company selected the SaM146 for its Superjet 100 regional aircraft, to be produced in 75 and 95-seat versions.
The SaM146 utilizes a single-stage turbine and as a new design has been developed to meet current and projected environmental standards, including regulations of the ICAO Committee of Aviation Environmental Protection Sixth Session (CAEP VI), set to become effective in 2008.
