Japanese manufacturer IHI and France’s Safran group have been confirmed as participants in the GE9X engine programme, which concerns the powerplant for the forthcoming 777X.
IHI is responsible for the design and manufacturing of components in the low-pressure turbine and the fan mid-shaft, while Safran oversees the same for the composite forward fan case and the turbine rear frame.
Meanwhile CFAN – a GE-Safran joint venture – is producing the composite fan blades for the engine. External suppliers, which also include MTU Aero Engines, will provide a quarter of components for the GE9X.
"These participants contributed to the successful start of the GE9X first engine to test two days ahead of schedule and the combined technologies of GE and our participants have performed extremely well,” said Bill Fitzgerald, VP of GE Aviation's commercial engine operation.
GE9X certification is expected in 2018.
