CFM International expects to start testing a technology demonstrator for its Rise open fan within the next 24 months. Executives at the French-U.S. engine maker told a pre-Paris Air Show briefing on Saturday that it will meet its promise of at least a 20 percent reduction in fuel burn compared with today’s Leap engines in time to support new narrowbody airliners now under development at airframers including Airbus and Boeing.

In the last few weeks, the Safran/GE joint venture’s engineers at Evendale, Ohio, began testing high-pressure turbine blades in a core based on the F110 powerplant. They also have used super-computers to assess new turbine airfoils, nozzles, and blades for Rise in a process that GE Aerospace head of engineering Mohamed Ali said has generated “fascinating, revolutionary results in terms of fuel burn and durability.” The company uses various additive and ceramic manufacturing techniques to make the new components.
