摘要

Following certification of the GE9X turbofan for Boeing's 777X, GE Aviation aims to complete testing for Extended Operations approval by year-end and is preparing another engine for validation tests of an innovative flow-inducer device designed to reduce the impact of dust and debris on durability The GE9X, which is the largest turbofan ever developed, is due to enter service on the 777-9 in 2022 with airlines such as Emirates Airline that operate in challenging hot and dusty environments. To improve the engine's durability and resistance to sand and dust, GE has incorporated a new layer of protection. This goes beyond the engine's standard variable bypass valve system, which rejects debris from the core, to add a system that filters particles out of cooling bleed air.
