The GE90 made the Boeing 777 famous for enormous engines. The 777X takes the idea further with the GE9X—a larger fan, fewer composite blades and a much more efficient core.

The Boeing 787 Dreamliner is unusual because airlines could choose between two very different engine families. Here is how the GEnx-1B and Trent 1000 differ—and how Boeing designed the aircraft to work with both

The Boeing 737 MAX replaced the CFM56-7B with a larger, more advanced LEAP-1B. That change affected far more than fuel efficiency—it changed how the engine, nacelle, wing and aircraft aerodynamics had to work together.

Boeing builds airplanes, but companies such as CFM, GE Aerospace and Rolls-Royce build their engines. Here is how the two complex machines are engineered to work together.
