Scientific breakthroughs bring new technologies to life

CFM optimizes the entire CFM56 propulsion system by combining advanced, aerodynamic design codes with sophisticated materials and innovative combustion.

CFM engineers use their understanding of aerodynamics to design 3-D aero parts that are shaped for smoother and more efficient interaction with surrounding air. We introduced second-generation 3-D aero design high-pressure compressor turbine blades with Tech Insertion in 2007. The next CFM engine will incorporate third-generation 3-D aero design.

We’re placing a major focus on developing composites. These extremely strong materials can be intricately formed and their use allows for fewer and more efficient engine parts. Accompanied with advanced coatings, they better withstand heat for longer life.

To reduce NOx dramatically in the future, CFM is refining the ultramodern Twin Annular Pre Swirl (TAPS) combustor. TAPS will reduce NOx emissions by 50 percent compared to the ICAO CAEP/6 limits that took effect in 2008.
