Why Might This Monster Jet Engine Have Airbus Worried?

The GE9X, when it enters service with the Boeing 777X, will be the largest jet engine in history. It will be the latest in a line of big twin-aisle engines that have steadily made long-haul flying quieter, cleaner, and more economical. You can also think of it as a careful blend of strength and utility, with a huge front fan improving fuel efficiency while advanced lightweight materials used in the engine’s construction help reduce its overall weight. This design helps the engine make less noise without sacrificing thrust.
