The PowerJet SaM146 turbofan that France’s Safran is showing in scale model form here at the Dubai Air Show (Stand W510) represents not just the application of engine subsidiary Snecma’s CFM56 experience to a regional jet-size engine but one of the most ambitious attempts yet to combine the strengths of Western and Russian aerospace technology.

The new engine offers thrust ratings from 15,400 to 17,500 pounds, selectable without modification to the engine via the full-authority digital engine control (fadec). That range bridges the gap between the two main regional jet variants of CFM partner General Electric’s CF34–the 14,000-pound CF34-8 that powers the Bombardier CRJ700/900 and Embraer 170/175, and the 18,000-20,000-pound CF34-10 used by the Embraer 190/195 and selected for China’s ARJ21.
