“The entire GE9X team devoted countless hours to enable this achievement to occur,” said Bill Millhaem, general manager of the GE90/GE9X engine programs at GE Aviation. “The ground testing will generate data on the full engine system and aerodynamic performance, mechanical verification, and aero thermal system validation.”

Maturation testing of the GE9X engine already started about 5 years ago and has progress from component-level to the first full engine to test (FETT). The FETT brings all the GE9X technologies together to demonstrate their operability. 

Compared to other engines, the GE9X FETT happened earlier in the development, just 6 months after the design was finalized. This timing assures all learnings from the FETT testing will be in the certified engines. Engine certification will be achieved in 2018.

With almost 700 GE9Xs on order, it will be the largest engine with a front fan at 134 inches of diameter with 16 carbon fiber composite blades. It will be in the 100,000 pound thrust class. It will have a 27:1 pressure-ratio 11-state high-pressure compressor. 

IHI Corporation, Snecma and Techspace Aero (Safran) and MTU Aero Engines AG are participants in the GE9X program
