The GE9X is a high-bypass turbofan purpose-built for the Boeing 777X.
The GE9X engine features a 134-inch composite fan with only 16 blades, reducing weight and drag.
KEY POINTS
- It achieves a market-leading bypass ratio near 10:1 and an overall pressure ratio around 60:1.
- Advanced ceramic-matrix composites and additive manufacturing reduce cooling needs and engine mass.
- The GE9X delivers about 10% lower fuel burn than the GE90, directly challenging Airbus's A350-1000 economics.
- Despite FAA certification in 2020, GE9X's service entry is delayed until at least 2027 due to Boeing 777-9 schedule.
