The General Electric Aviation GE9X is a high-bypass turbofan aircraft engine, developed by the GE Aviation for the Boeing 777X. Derived from the GE90, it should improve fuel efficiency by 10%.
GE engines are bombarded with exposure to ice, dust and debris for hundreds of hours. Before the Federal Aviation Administration – FAA approves them for commercial jets.
One of the final hurdles is GE Aviation’s Bootcamp for jet engines. These tests to the GE9X simulate 3,000 takeoffs and landings.

The GE9X is the largest jet engine ever built. GE9X features 16, 3D printed, composite fan blades, each one more than 11 feet in diameter and it can generate 105,000 pounds of thrust. The engine is nearly as large in diameter as the body of an entire Boeing 737.
Is the new GE9X engine on Boeing's 777X as big as a 737 fuselage? No. It’s even bigger. pic.twitter.com/x2s3XXwZTC

The fuel nozzles are also 3D printed.
A manufacturer added that this new engine will produce less noise and fewer emissions than its predecessors. It has parts made from super ceramics and 3D-printed materials, which weigh less than traditional metal parts and generate more power while burning less fuel.
Nearly 700 GE9X engines are already on order.
