GE9X Engines Nearly Ready for 777X Flight Tests

GE Aviation has delivered the first three fully compliant GE9X turbofans to Boeing’s Everett, Washington, widebody plant following retrofit of redesigned Stage 2 stator vane assemblies in the engines' compressors, GE9X program head Ted Ingling reported just ahead of the Dubai Air Show. Ingling explained that the process that led to the fix to the titanium part involved revamping the geometry to ensure a proper wear profile. With testing completed, GE has now retrofitted the fix on six engines, the fourth of which it was preparing to send to Everett when Ingling spoke with AIN on November 8.
