Commercial Jet Engines & Propulsion Systems
Technical specifications, bypass ratios, thrust ratings, fuel burn improvements, and active fleet deployment for modern commercial turbofan powerplants.
Leading Commercial Turbofan Engines
CFM LEAP-1A
CFM International (GE Aerospace / Safran)
The LEAP-1A is one of two engine choices powering the Airbus A320neo family, featuring 3D-woven carbon fiber composite fan blades and ceramic matrix composites in the high-pressure turbine.
CFM LEAP-1B
CFM International (GE Aerospace / Safran)
The exclusive powerplant for the Boeing 737 MAX series, custom-tailored with a 69-inch fan diameter to meet landing gear ground clearance requirements.
Pratt & Whitney PW1100G-JM (GTF)
Pratt & Whitney
The PW1100G incorporates a 3:1 reduction gearbox between the low-pressure spool and the front fan, enabling optimal aerodynamic speeds across all stages.
Rolls-Royce Trent XWB
Rolls-Royce
The Trent XWB is the sole powerplant for the Airbus A350 family, delivering industry-leading thermal efficiency across ultra-long-haul intercontinental routes.
GE Aerospace GEnx
GE Aerospace
The GEnx utilizes composite fan blades and a lean-burn TAPS combustor, capturing over 65% market share on the Boeing 787 Dreamliner program.
GE Aerospace GE90-115B
GE Aerospace
The GE90-115B set the Guinness World Record for the highest thrust achieved by a jet engine (127,900 lbf), powering the long-haul Boeing 777-300ER fleet.
