GE Aviation starts first full development engine testing

Ground testing is underway on the first full GE9X development engine, which is the world’s largest commercial aircraft engine, at GE Aviation’s Peebles Testing Operation.

“The entire GE9X team—from engineering to sourcing to value streams to development assembly—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.”

“We would like to convey our congratulations to the GE team for its achievement of this milestone,” said Bob Feldmann, Boeing 777X vice president and General Manager. “GE’s commitment to technology maturation throughout the GE9X development program continues to deliver results for the 777X program. We look forward to working together with GE to deliver this great airplane to our customers.”

With almost 700 GE9X engines on order, the GE9X engine will be in the 100,000 pound thrust class and will have the largest front fan at 134 inches in diameter with a composite fan case and 16 fourth generation carbon fiber composite fan blades. Other key features include; a next-generation 27:1 pressure-ratio 11-stage high-pressure compressor; a third-generation TAPS III combustor for high efficiency and low emissions; and CMC material in the combustor and turbine.

Along with GE Aviation technology and advanced material, the GE9X engine also contains the low-pressure turbine module and accessory drive train (ADT) kit composed of the inlet gearbox, transfer gearbox and accessory gearbox, connecting shafts and related attachments) from Avio Aero, a GE Aviation business.
