The GE9X is the largest and most powerful commercial aircraft engine ever built, incorporating advanced technologies that enable more efficient, quieter and cleaner travel. Designed specifically for the new twin-engine Boeing 777X family, the GE9X is the most fuel-efficient engine in its class, delivering unmatched reliability and performance.
World record holder for the highest thrust, at 134,300 pounds.
The most advanced technologies and materials
Innovation is in our DNA. Like every engine that we have ever built, new technologies and materials incorporated into the design are key to delivering the world-class reliability, efficiency, and performance GE engines are renowned for
This blend of evolutionary and revolutionary designs enables the GE9X to be the most fuel-efficient jet engine GE has ever produced on a per-pounds-of-thrust basis. The GE9X powering the 777X airplane family:
DELIVERS UP TO 10% SPECIFIC FUEL CONSUMPTION IMPROVEMENT VERSUS THE GE90-115B ENGINE
PROVIDES A 5% SPECIFIC FUEL CONSUMPTION IMPROVEMENT VERSUS ANY TWIN-AISLE ENGINE AVAILABLE
ACHIEVES AN APPROXIMATE 10:1 BYPASS RATIO PLUS A 60:1 OVERALL PRESSURE RATIO AND MARGIN TO STAGE 5 NOISE LIMITS
Fewer fan blades provide greater efficiency
Reduced fan blade thickness improves aerodynamic efficiency, while its lower fan radius ratio maximizes air flow and minimizes drag. Combined with fewer fan blades than its commercial counterparts, GE9X boasts the most efficient fan to increase performance and decrease fuel burn.
