GE9X jet engine faces unique scaling problems
1 min read
GE Aerospace built the GE9X for the Boeing 777X, a 134-inch fan engine generating 134,300 pounds of thrust. The 777X program is 6 years behind schedule with $15 billion in spending. Issues include supersonic blade tips, ground clearance requiring longer landing gear, and 21,000-pound weight creating rotational inertia.
