Hawaiian Airlines selected the GEnx-1B engine to power its intended purchase of 10 Boeing 787 Dreamliners. The engine order will be valued at more than $520 million (USD) list price.
Close to 1,900 GEnx engines have been sold to about 50 customers. Compared to GE's CF6 engine, the GEnx engine offers up to 15 percent better fuel efficiency, which translates to 15 percent less CO2. The GEnx's innovative twin-annular pre-swirl (TAPS) combustor dramatically reduces NOx gases as much as 55 percent below today's regulatory limits and other regulated gases as much as 90 percent. Based on the ratio of decibels to pounds of thrust, the GEnx is the quietest engine GE produces due to the large, more efficient fan blades that operate at slower tip speed, resulting in about 40 percent lower noise levels.
GEnx's revenue-sharing participants are IHI Corporation of Japan, Volvo Aero of Sweden, MTU of Germany, TechSpace Aero (Safran) of Belgium, Safran Aircraft Engines of France and Samsung Techwin of Korea.
