With its superior efficiency, the GEnx powers many of the longest 787 Dreamliner routes, including Qantas’s 787-9 recording-breaking nonstop flight from New York to Sydney.

As the world’s first commercial engine with both a carbon-fiber composite front fan case and fan blades, the GEnx fan module is lighter in weight and corrosion resistant, offering customers less line maintenance and improved reliability with less noise.

After introducing composite fan blades on the GE90 engine in 1995, we took the technology to a new level with the GEnx. The carbon-fiber composite fan blades on the GEnx engine feature a more efficient design, a reduced blade count (from 22 to 18 fan blades), and a composite fan case for further weight reduction.

Cutting edge materials including additively manufactured parts. The first 3D-printed part installed on a GEnx was approved by the FAA in November 2018 for the power door opening system (PDOS) bracket.

The GEnx's innovative lean-burning twin-annular pre-swirl (TAPS) combustor dramatically reduces NOx and other regulated gases below today's regulatory limits and enhances durability.

The GEnx low-pressure turbine (LPT) is lighter and more efficient than its predecessor and incorporates next-generation 3D aerodynamics. It also introduces titanium aluminide blades to stages 6 and 7, reducing engine weight by approximately 300 lbs. and contributing to increased fuel efficiency on the GEnx engine.
