The largest and most powerful commercial aircraft engine ever built
The GE9X is the largest and most powerful commercial aircraft engine ever built, incorporating advanced technologies that enable more efficient, quieter flight with fewer emissions. 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.
Purpose built for the Boeing 777X family of aircraft
The GE9X represents a multi-generational technology development chain, supported by millions of hours of field experience. We have pulled learnings from other engines, including the GE90 and GEnx, to enable a more efficient, more reliable, quieter engine with lower emissions.
Combined with the Boeing 777X, the GE9X delivers the best airline economics and profitability via reduced fuel consumption, emissions, and associated costs, and lowest environmental impact.
Fuel consumption improvement
Provides a 5% specific fuel consumption improvement versus any twin-aisle engine available.
Fuel consumption improvement
Delivers up to 10% specific fuel consumption improvements versus the GE90-115B engine.
Composite fan blades
Fourth-generation composite fan blades maximize airflow and minimize drag.
Bypass ratio
Achieves an approximate 10:1 bypass ratio plus a 60:1 overall pressure ratio and margin to stage 5 noise limits.
134-inch front fan diameter
Larger than a Boeing 737 fuselage, the GE9X fan diameter enables a higher bypass ratio for maximum efficiency.
Fewer fan blades provide greater efficiency
The GE9X has six less fan blades than the GE90 engine.
