Last month, the GEnx completed its flight test program on GE’s Boeing 747 flying test-bed, “which validated the GEnx-1B engine’s performance in real world flight conditions”, says GE.

GEnx engines have a bypass ratio of 9.5 — an early 1950s-era jet engine’s bypass ratio was 0.3, for comparison — which means that the fan now constitutes 33 percent of the engine’s weight, reports ...

The update by the NTSB reveals there remain concerns about the 747-8 engine. It seemed only a week ago that a string of three high-profile GEnx engine incidents on both the 787 and 747-8 since ...

The GEnx also utilized carbon fiber composites for the fan case to reduce the engines weight by close to 400 pounds." "The GE9X will have just 16 fan blades on its 134-inch front fan.

The repair involves shaving metal from the case surrounding the fan, giving the blades more clearance. The latest incident occurred at 20,000 feet, lower than previous icing problems in the GEnx.

Developed by General Electric, the GEnX engine combines decades of research in materials science and fluid dynamics to deliver powerful, efficient propulsion for the Boeing 787. The design ...

General Electric Co.'s GenX engine passed a critical first test of a new configuration--a composite fan case and composite blades--that promises significant weight reduction. In a blade-out rig ...

Volvo Aero highlighted the successful test of its components in the fan blade test out of the General Electric GEnx engine late last week. Volvo Aero designed two parts used to affix the engine to ...

The 787 involved was powered by General Electric ’s GEnx engine. The NTSB has determined that a mid-shaft engine fan fractured during the failure. The safety board is continuing its investigation.

The National Transportation Safety Board said Wednesday a 787 Dreamliner's GE engine failed on the runway in North Charleston, S.C., last month because of a fractured fan shaft.

Japan Airlines operates other GE engines, including the CT7, CF34, CF6, and GE90. The first full GEnx engine will be tested in 2006. The engine is expected to be certified in 2007.
