Tested for years. Confidence from day one.
With the most extensive technology maturation program in the history of GE Aviation, the GE9X engine will deliver world-class reliability and performance at service entry. But first, components undergo rigorous testing at specialized facilities around the globe.
Low pressure turbine testing (Massa, Italy & Evendale, Ohio)
Designed to be the largest and most efficient ever made, the LPT is built with state-of-the-art materials and processes that are tested, refined and tested again.
Fan blade testing (Seattle, WA)
See how scaled 4th-generation composite fan blades are used to validate the 16-count design – the lowest of any twin-aisle engine available.
In more than a century of building engines and powering flight, GE Aviation has never stopped innovating. All those years of research, testing and development will come together to power the new Boeing 777X airplane with the all-new GE9X commercial engine, built on a proven architecture while incorporating the latest technologies and materials.
The most advanced technologies and materials
A blend of evolutionary and revolutionary designs will enable the GE9X to be the most fuel-efficient jet engine GE has ever produced on a per-pounds-of-thrust basis. It’s designed to deliver a 10% improved aircraft fuel burn versus the GE90-115B-powered 777-300ER and a 5% improved specific fuel consumption versus any twin-aisle engine available, plus achieve an approximate 10:1 bypass ratio, a 60:1 overall pressure ratio and margin to Stage 5 noise limits.
