Delivering Proven Performance
As the fastest-selling, widebody jet engine in GE Aerospace history with more than 3,000+ engines in-service and on order, the GEnx delivers proven performance for the Boeing 787 Dreamliner and Boeing 747-8.
The engine’s leading-edge technologies and advanced architecture offer:
99.98 dispatch rate, 3 times higher time on wing, and 3 times fewer significant events
1.4% better SFC vs. the competition for a 3,000 nautical mile mission
3% higher annual utilization means 7 more days per year of aircraft availability
Advanced materials provide greater durability, lighter weight, and higher LLP lives
With its superior efficiency, the GEnx powers many of the longest 787 Dreamliner routes, including Qantas’s 787-9 recording-breaking non-stop flight from New York to Sydney.
Designed for Performance and Reliability
Less Line Maintenance
As the world’s first commercial engine with both a carbon fiber composite front fan case and fan blades, the GEnx fan module is lighter in weight and corrosion resistant, offering customers less line maintenance and improved reliability with less noise.
More Efficient Design
After introducing composite fan blades on the GE90 engine in 1995, we took the technology to a new level with the GEnx. The carbon-fiber composite fan blades on the GEnx engine feature a more efficient design, a reduced blade count (from 22 to 18 fan blades) and a composite fan case for further weight reduction.
Cutting Edge Materials
Cutting edge materials including additively manufactured parts. The first 3D printed part installed on a GEnx was approved by the FAA in November 2018 for the power door opening system (PDOS) bracket.
The GEnx's innovative lean burning twin-annular pre-swirl (TAPS) combustor dramatically reduces NOx and other regulated gases below today's regulatory limits and enhances durability.
The GEnx low-pressure turbine (LPT) is lighter and more efficient than its predecessor and incorporates next-generation 3D aerodynamics. It also introduces Titanium Aluminide blades to stages 6 and 7, reducing engine weight by approximately 300 lbs. and contributing to increased fuel efficiency on the GEnx engine.
