Following an extensive technical evaluation, GE was specified by The Boeing Company to develop a 110,000 to 115,000 pound-thrust GE90 derivative engine for the longer-range 777-200LR, -300ER and 777 Freighter aircraft. The Boeing 777-200LR and 777 Freighter normally only require the derated GE90-110B engines.
Improvements in advanced technologies that were introduced on the original GE90 engine in 1995 are incorporated into the latest and world's most powerful jet engine. The GE90-115B is the most efficient widebody engine in its class. It offers the enhanced performance and efficiency of three-dimensional, aerodynamic (3D aero) compressor airfoils and wide-chord, swept, composite fan blades, which are both durable and low-maintenance.
This engine's performance and efficiency, coupled with its dual annular combustor technology, significantly limits fuel consumption and restricts hydrocarbon emissions to 40 percent of the level permitted by current international standard. Additionally, the -115B allows 10 percent longer time-on-wing, which translates to 10 percent less in maintenance costs.
This derivative engine represents the successful culmination of GE's strategy in the early 1990s to build a new centerline engine for the Boeing 777 family. During its testing, the GE90-115B set numerous aviation records, including reaching a sustained record 127,900 lbs. of thrust during initial ground testing at GE's outdoor test facility near Peebles, Ohio.
Since its entry into service, the GE90-115B engine has proven to be one of the quietest engines per pound of thrust and is part of GE's "ecomagination" product portfolio - GE's commitment to implementing innovative, cost-effective technologies that enhance the customers' environmental and operating performance.
