GE Earns FAA Certification for Boeing 777X Engine

GE Earns FAA Certification for Boeing 777X Engine

The Boeing 777X project will have engines certified by the Federal Aviation Administration. Engine builder GE announced that GE9X, billed as the largest jet engine in the world, received certification after the evaluation of eight test engines.

Engine builder GE is officially approved to provide the “largest jet engine in the world,” the GE9X, for the upcoming Boeing 777X project. In a blog, the manufacturer announced the powerplant received certification from the Federal Aviation Administration.

134-Inch Fan Diameter Engine Provides Over 100,000 Pounds of Thrust

For evaluation, the FAA was given eight engines, completing just under 5,000 hours and 8,000 cycles. After being put through the paces, the GE9X was given the green light to power the upcoming Boeing 777X project. The company says their focus is to continue working with Boeing to deliver the first engines to be used for the flight test program. Boeing currently has eight engines and spare parts for their four test airframes.

Compared to the prior-generation GE90-115B, the GE9X is designed to achieve 10 percent less specific fuel consumption, while emitting less smog. Even with slightly more fuel efficiency, the 134-inch fan diameter is designed to provide over 100,000 pounds of thrust. The engine is as wide as a Boeing 737, with components made of advanced carbon fiber.

“Just as the GE90 pioneered new technology for commercial aircraft engines more than 25 years ago on the Boeing 777, the GE9X sets the new standard for engine performance and efficiency,” Bill Fitzgerald, vice president and general manager of GE Aviation commercial engines operations, said in the blog. “Thanks to the incorporation of GE’s most advanced technologies developed over the last decade.”

GE says they have received over 600 orders for the GE9X engine. Prospective operators include All Nippon Airways, British Airways, Emirates, Lufthansa, and Singapore Airways.

Engine Certification Completes GE Next Generation Line

With the certification of the GE9X complete, the next-generation project of GE Aviation engines is done. The GE9X will join the GEnx, designed for the Boeing 787 Dreamliner, and the CFM LEAP Engine, which is used on the Boeing 737 MAX and COMAC C919.
