PEEBLES, OHIO – – Ground testing is underway on a GEnx engine that contains lightweight, heat-resistant ceramic matrix composite (CMC) components in the high-pressure turbine (HPT) and combustor as part of the technology maturation program for the GE9X engine that will power the Boeing 777X.

“For the GE9X, GE is applying its extensive knowledge of CMCs into the engine’s hot section,” said Bill Millhaem, general manager of the GE90/GE9X engine programs. “The GEnx engine testing campaign, which began in late January, will allow us to demonstrate the functionality and durability of the full suite of CMC hot section components and help the team lock down the final design for the new GE9X engine by mid-2015.”
