The engine that will eventually power our new 777X has now started ground testing. The GE9X is being tested at GE Aviation’s Peebles Testing Operation in Ohio.

This marks a significant milestone in the development of the engine and the program.

Maturation testing of the GE9X began five years ago and has progressed from component-level all the way to the first full engine to test—also known as FETT.

FETT brings all the GE9X technologies together to demonstrate what they can do as a complete propulsion system. This also gives early information on the engine’s aerodynamic and thermal characteristics.

GE Aviation says the results of the initial engine run were very positive. Boeing looks forward to working together with GE to deliver the 777X to customers.
