GE launches eCore engine technology

GE's new engine technology uses ceramic composites and is based on the company's GEnx engine.

GE Aviation (Cincinnati, Ohio) announced on July 13 that it has launched a new engine core program, called eCore, as the technology cornerstone for a new generation of jet engines for narrow-body, regional, and business jets.

The program is designed to offer aircraft operators up to 16 percent better fuel efficiency over GE’s best engines in operation today.

The engine “core” – comprised of the compressor, combustor, high-pressure turbine – is the heart of a jet engine. It’s where air is compressed and mixed with fuel to drive turbines, and create thrust. To this core, the fan system is attached to complete a jet engine.

Leveraging GEnx technologies, the eCore program features advanced materials (such as ceramic matrix composites), new cooling technologies, next-generation TAPS (Twin-Annular, Premixed, Swirler) combustor for efficient and cleaner fuel combustion and new 3-D aerodynamic design airfoils.

The first eCore will run in 2009 for GE’s joint technology efforts with Snecma (SAFRAN Group) on the next-generation CFM engine for narrow-body aircraft. CFM International is a 50/50 joint company of Snecma and GE.
