GE Aviation confirmed on Monday (April 11) that it has started ground testing the GE9X, the sole engine option for the 777X aircraft.
Testing of the engine began at the OEM’s facility in Peebles, Ohio, with flight testing and certification set to follow next year.
Certification of the engine is expected for 2018.
Bill Millhaem, general manager of the GE90/GE9X engine programmes, said the ground testing will generate data on the full engine system and aerodynamic performance, mechanical verification, and aero thermal system validation.
GE currently has orders for nearly 700 GE9X engines, including a commitment from Emirates for 300 units placed at the Dubai Air Show in 2013.
