Born of power and efficiency
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
Engineered with the environment in mind
The GE9X features the same world-class reliability as the GE90-115B, with noise and NOx emissions well below anticipated regulation standards. Environmental performance highlights include:
50% lower emissions
All emission values equal or exceed current regulatory requirements and are expected to remain well below the requirement for many years to come.
The GE9X engine produces half the NOx of any engine in its class at a level that is less than half of current requirements.
Tested for years. Confidence from day one.
The GE9X has had the most extensive technology maturation program in the history of GE Aviation to ensure world-class reliability and performance at service entry. Prior to installation, components undergo rigorous testing at specialized facilities around the globe.
" It takes the world’s best talent in jet propulsion to create a game-changing product like the GE9X engine. There is no substitute that can achieve the combination of size, power and fuel efficiency of the GE9X. This engine will deliver unsurpassed value and reliability to our airline customers."
