[The latest generation GE90, the 115B, is the most powerful commercial jet engine ever.]
[It powered the longest nonstop commercial flight on record.]
[ Most visible are the swept fan blades]
[optimized by lightweight composits]
[pulling unprecedented amounts of air in and around the engine.]
[The 115B delivers the highest bypass ratio in airline service.]
[By incorporating a unique debris rejecting system,]
[particles entering the fan are centrifuged away from the core]
[providing the purest possible air supply.]
[With the efficiencies of 3D aerodynamics, an advanced one-piece bladed disk]
[and one fewer stage, this compressor uses 20% fewer parts than its predecessors]
[while still delivering an astounding 19:1 pressure ratio.]
[The result is 15% less fuel consumption while maintaining GE's hallmark stall-free operation.]
[By taking the best features of our most proven combustors,]
[the 115B has significantly reduced liner temperatures by optimizing cooling air]
[resulting in improved durability.]
[In addition, these improvments provide more consistent temperature profiles throughout]
[and a reduction in combustor maintenance costs.]
[Advanced turbine materials and a 30% improvement in cooling effectiveness]
[Utilizing 3D aerodynamic technology, ]
[the number of air foils in the low-pressure turbine]
[has been reduced by 10% while performance retention has also been improved.]
[The GE90 incorporates an innovative and unique architecture ]
[that simplifies transportation and reduces the cost of air engine acquisition up to 15%.]
[This structural design allows the fan and the propulsor]
[to be easily separated into two modules,]
[and, inherent in all twin-engine aircraft, ]
[two engines are less expensive to maintain than four.]
[The GE90-115B has exceeded expectations on all commitments]
[proving this engine to be the most advanced turbo fan in service today.]
[This engine is so reliable that it will ultimately enable extended operations]
