Advanced material and finishing technique make debut on Passport engine

The Passport engine for the Bombardier Global 7000 and Global 8000 aircraft incorporates ceramic matrix composite (CMC) material and a unique blade surface that will improve performance, reduce fuel burn and enhance durability. “GE Aviation invests close to $1bn annually on research and development of advanced technologies and materials, and the Passport engine is benefitting from these efforts,” said Brad Mottier, vice president and general manager of the Business & General Aviation and Integrated Systems organization at GE Aviation. “The Passport engine will be the first non-military engine to use Oxide-Oxide (Ox-Ox) CMCs and the first GE business aviation engine to feature super finish. These features will provide significant advantages to our customers.”
