Description: The CFM International LEAP-X is an entirely new baseline turbofan engine intended to power future replacements for current narrow-body aircraft such as Boeing 737s and Airbus A320s. The new engine leverages the technologies developed under CFM-funded LEAP56 technology acquisition program which started in 2005. CFM International plans to get the first engine demonstrator running by 2012 and achieve engine certification by 2016. The LEAP-X will reduce fuel burn by up to 16 percent compared to current CFM56 Tech Insertion engines.

The new engine's core will feature eight-stage compressor and single-stage turbine. LEAP-X will incorporate three-dimensional, woven resin transfer molding (3-DW RTM) technology that dramatically reduces engine weight while providing a more durable blade as well as Titanium-Aluminide (Ti-Aluminide) lightweight alloy. The 3-DW RTM technology is expected to reduce the engine weight by 400 pounds and the composite fan blade count by 25 percent.

In December 2009, AVIC1/COMAC of China selected the LEAP-X1C, now LEAP-1C, engine from CFM International to power its single-aisle airliner called the C919.
