AerCap selected the GEnx-1B engine to power its 15 Boeing 787 Dreamliners with the option to purchase 10 additional aircraft. The engine order is valued at more than $780 million (USD) list price and increases AerCap's GEnx-powered 787 Dreamliner fleet to 49 firm aircraft.

Philip Scruggs, President and Chief Commercial Officer, AerCap, said, "We are pleased to provide our customers with the most modern, fuel efficient aeroplanes and engines in the world. We look forward to receiving further 787 Dreamliners powered by the GEnx-1B engine."

"AerCap's order for additional GEnx-1B engines reaffirms the engine's status as the engine of choice on the Boeing 787 aircraft," said Chaker Chahrour, vice president and general manager of Global Sales and Marketing for GE Aviation. "We take great pride in AerCap's continued confidence in the engine line and look forward to further strengthening our relationship."

More than 1,600 GEnx-1B engines have been sold to more than 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.
