GE Aviation received the largest order from an airline in its history for the GE9X, the world’s largest jet engine, at the Dubai Air Show on Sunday. A flock of 450 new GE9X engines, whose front fan is 11 feet in diameter, will power a fleet of next-generation Boeing 777X aircraft ordered by Emirates, Qatar Airways and Etihad Airways.
The total value of the deal, which also includes service agreements, is $26 billion (list price in U.S. dollars). Emirates alone agreed to purchase 300 GE9X engines, valued at $11 billion, making it the largest order from an airline in GE Aviation’s history.
The GE9X engine, which is still in development, builds on the legacy of the GE90, the world’s most powerful jet engine. The new engines will use advanced parts and materials like 3-D printed fuel nozzles, carbon composite fan blades and heat-resistant ceramic matrix composites inside the high-pressure turbine. The new technologies will make the engine lighter, quieter and more fuel efficient. They will also help reduce emissions.
