JAL Selects GEnx Engines for 787 Dreamliner

Tokyo, Thursday November 24: Japan Airlines has selected the GEnx engine made by the GE Company to power its Boeing 787 Dreamliner aircraft, due to enter service with the airline from 2008.

In December 2004 JAL decided to introduce 30 Boeing 787s with options for 20 more as the replacement aircraft for medium size jet airliners, without specifying the choice of engines. After studies, JAL has decided on the GEnx for installation on two types of the new generation aircraft, the long range 787-8 and the short to medium range 787-3.

JAL will introduce the more efficient, economical and environment-friendly 787 Dreamliner on domestic and international routes.

The GEnx engine is derived from the GE90 series of engines, currently in JAL service on its Boeing 777-200ER and 300ER aircraft. The new technology GEnx will deliver up to 15% better fuel consumption than current equivalent engine types. According to GE, maintenance needs are reduced because of 30 percent fewer parts, enabling the engine to be in service for longer periods than current models.

Manufacturers GE claim that the engine emissions will be as much as 95% below current regulatory limits, making the new engine one of the most environmentally friendly engines in airline service.
