GE Aviation says that it has begun certification tests of the GE9X engine which will power Boeing’s new 777X aircraft.

The GE9X engine will be in the 100,000 pound thrust class and has a large, 134 inches diameter front fan featuring a composite fan case and 16 carbon fiber composite fan blades.

‘Completing a full year’s worth of validation efforts on the FETT engine gave us great confidence heading into the certification program with the second GE9X engine,’ said Ted Ingling, GE9X general manager at GE Aviation. ‘By incorporating all the learnings from the FETT engine, we start the GE9X certification program with a stable configuration and position ourselves to meet the schedule and performance expectations of our customers from Day 1 of service entry.’
