GE conducting ceramic matrix composite components testing for GE9X

As part of GE9X engine development for the Boeing 777X, GE Aviation has started ground tests on a GEnx engine containing ceramic matrix composite (CMC) components in the high pressure turbine and combustor.

The lightweight, heat-resistant CMC components will play an important role in the “hot section” of the GE9X. GE90/GE9X engine programs VP Bill Millhaem said in a statement, “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.”

The testing is occurring at GE's Peebles, Ohio facility. “CMCs are made of silicon carbide ceramic fibers and ceramic resin, manufactured through a highly sophisticated process and further enhanced with proprietary coatings,” GE said. “CMC components are ultra-lightweight with one-third the density of metal, providing weight reduction that enables better fuel efficiency. CMC material is more durable and allows engines to stay on wing longer. The material is also more heat-resistant than metals and requires 20% less cooling air, which improves overall engine efficiency.”
