The airplanes that will replace today’s narrowbody aircraft must fly cleaner, quieter and more fuel efficient than ever before. This will demand a revolutionary engine, and CFM is the company that will deliver that engine.
LEAP-X will redefine the state of the art for short-to-medium range aircraft for decades to come.
Test results across the board are matching the aggressive targets set by CFM. The first LEAP-X is being readied for 2014 certification to coincide with the schedule of its launch aircraft – the Commercial Aircraft Corporation of China’s (COMAC’s) C919 narrowbody.
Heavily rooted in advanced aerodynamics, environmental and materials technology, LEAP-X gives customers a winning equation.
This new turbofan will run on 16 percent less fuel and emit 16 percent fewer CO2 emissions, compared to today’s best CFM56. Better for your budget.
LEAP-X will also be much quieter than current CFM56 engines.
The fan: lighter than ever, yet tremendously durable
A high bypass ratio comes with one of the most impressive components of this engine: a fan and casing built from advanced composite materials.
Far tougher than comparable metal blades, the fan's 3-D woven transfer molding blades allow a level of efficiency unprecedented by CFM56 engines today. The lightweight fan will take 500 pounds off each engine.
The MASCOT engine, a full-scale LEAP-X RTM demonstrator, has undergone extensive aerodynamic, performance, crosswind, and acoustic testing in France and the U.S. The engine will begin endurance testing by mid-2010.

The core: never so sophisticated
Ground testing is underway for the most advanced engine core CFM has ever built. Its pressure ratio is twice as high as that of current CFM56 engines. With an 8-stage compressor, innovative combustor and single-stage high-pressure turbine, the LEAP-X core will debut third generation 3D aerodynamic design airfoils, composite materials and new cooling technologies.
The LEAP-X core's most distinguishing feature is the ultramodern Twin Annular Pre Swirl (TAPS II) combustor that will dramatically reduce NOx emissions by 60 percent compared to current CAEP/6 regulations. Specifically built for operators who want to save on emissions fees.
The right sum for engine operators
LEAP-X, thoroughly tested and tried, will be worthy of inheriting the mantle of the world’s most reliable engine.
Expect the Power of the Future to produce 60% less NOx, 16% less CO2 emissions, burn 16% less fuel and fly quieter and 500 pounds lighter.
