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.

The General Electric GEnx ("General Electric Next-generation") is an advanced dual rotor, axial flow, high-bypass turbofan jet engine in production by GE Aerospace for the Boeing 747-8 and 787. The GEnx succeeded the CF6 in GE's product line.

2016年10月7日 · Based on the ratio of decibels to pounds of thrust, the GEnx is the quietest engine GE produces due to these large, more efficient fan blades that operate at slower tip speed, resulting in about 40 percent lower noise levels. Combined the composite fan case and fan blades, the GEnx is 350 lbs lighter per engine.

Like lightweight, durable composite materials and specialized coatings. An innovative, clean-burning combustor, a counter-rotating architecture. And a fan module that’s virtually maintenance-free. Designed around our customers’ needs, the GEnx represents a giant leap forward in propulsion technology.

GEnx作为B787的备选发动机，其做了许多革新：风扇直径2.8米（787-8）、复合材料制成的风扇叶片、钛铝合金制成的第6、7级低压涡轮风扇叶片。 为了减少燃油消耗，做到了19：2的涵道比，同时也有助于降低噪音，整流罩导向叶片有助于减少了二次流，双环预混旋流 ...

2004年12月14日 · The GEnx fiber-braided composite fan case, to be the first in commercial service, results from more than 20 years of GE research and development, including testing on a NASA demonstrator engine. In addition to weight savings, the fan case's composite properties create a tough, hard structure that eliminates the potential for corrosion.

2010年5月11日 · Walker explains that some of the features include third-generation composite fan blades, a new composite fan case, second-generation 3-dimensional aerodynamic (3-D aero) airfoils, a new...

2018年10月6日 · 在 GEnx中,采用了内置式喷水清洗装置,即在高压压气机前安装了圆周均布的四个喷水用的喷咀(如图15所示),每个喷咀喷射的散布角度较大,能遍布高压压气机进口环带,喷洗的效果较好。

Formed in 1993, CFAN is a 50/50 Joint Venture between GE Aviation & Safran Aircraft Engines of France. The partnership was created to introduce composite fan blades in a GE90 Engine that powers the Boeing 777.
