EVENDALE, Ohio - Since entering service in 1995, GE's GE90 engine family has reached 40 million flight hours, with more than 1,725 GE90 engines flying with 63 operators. Production levels for the GE90 engine rose from 180 engines in 2012 to 220 engines in 2013, with 230 engines scheduled for delivery in 2014. The engine backlog has grown to more than 600 engines.
The GE90 is providing the architecture for the new GE9X engine that will be in the 100,000 lbs. thrust class. Key features include a 133-inch diameter composite fan case and 16 composite fan blades; next-generation 27:1 pressure ratio 11-stage high pressure compressor; a 3rd-generation TAPS (twin annular pre-swirl) combustor for greater efficiency and low emissions; and ceramic matrix composite (CMC) material in the combustor and turbine. The GE9X compressor ratio of 27-to-1 will exceed the GE90-115B, coupled with a larger, higher-flow fan. This combination - which will be unique to jet propulsion - will be the centerpiece of GE's most fuel efficient jet engine ever with a 10 percent improvement in fuel burn over the GE90-115B.
The order book for the GE9X is growing rapidly. Since launching on the Boeing 777X last year, 600 GE9X engines were ordered by six operators.
