The Future of 737 Propulsion Looking ahead, the conversation surrounding the Boeing 737 engine type is evolving beyond fossil fuels. While the LEAP engine currently represents the pinnacle of conventional turbine technology for this airframe, Boeing and engine manufacturers are actively researching sustainable aviation fuel (SAF) compatibility and eventually, hybrid-electric or fully electric propulsion systems.

This synergy between airframe and engine is crucial for achieving the advertised improvements in efficiency and safety. While the CFM56 utilized a two-spool design, the LEAP employs a more advanced three-spool configuration, allowing for greater efficiency across different flight regimes.
Key Differences Between CFM56 and LEAP The distinction between the older CFM56 and the newer LEAP engines is profound, impacting everything from maintenance to aerodynamics. The LEAP engine incorporates advanced composite materials, such as ceramic matrix composites in the turbine blades, and features a larger, more efficient fan diameter.
