WASHINGTON - The FAA-certified GE9X, designed specifically for the Boeing 777X, has accomplished another milestone, with a new series of tests validating the enhanced durability of the engine, AviationPros report. Continue reading original article.

The Intelligent Aerospace take:

November 17, 2021 - GE Aviation engineers injected a stream of dust debris into a GE9X test engine to analyze how it would perform throughout the entire flight envelope, from takeoff through cruising speed and landing.

“Our test findings further validate our confidence that the GE9X will meet the durability and reliability expectations of our customers upon entry into service,” said GE9X program general manager Karl Sheldon. “After 1,600 cycles of test execution and post-borescope inspection, all components functioned as expected. A full module and component tear down will commence and complete by the end of the year.”

These test simulations represent the everyday flying the GE9X engine will perform in some of the harshest environments found around the world.
