[Based on advanced and proven technologies,]
[it represents a giant leap in aircraft propulsion.]
[Up front, third generation carbon fiber fan blades are made of light,]
[incredibly strong and durable composites.]
[The GEnx is the only turbo fan with both case and fan blades made of composites,]
[which reduce the weight of each engine by more than 350 pounds.]
[Next, the advanced low pressure compressor ]
[incorporates the latest 3D aerodynamic improvements]
[and a debris rejecting system to keep foreign material from entering the core.]
[At the heart of the GEnx is the most efficient,]
[compact core we've ever produced.]
[It features a 10-stage high pressure compressor]
[that uses four fewer stages than the engine it will replace.]
[This efficient compressor will deliver an astounding 23 to 1 pressure ratio,]
[enabling lower fuel burn while providing our legendary stall-free operation.]
[The advanced TAPS combustor keeps temperatures low]
[by utilizing lean burn combustion and a more uniform temperature profile.]
[The result: Reduced NOx emissions and longer life of downstream hardware.]
[Here in the turbines, fewer blades now do more work.]
[A counter-rotating architecture enables a more efficient extraction]
[and 10% fewer parts in select stages.]
[Integrated diagnostic technology allows the GEnx to monitor its own condition]
[When a GEnx has to come off wing, it splits into two modules:]
[The propulsor can easily be removed and a spare one connected ]
[to the maintenance-free fan module.]
[This enhances transportability and helps reduce spare engine acquisition costs]
[by up to 10% while minimizing maintenance overhead.]
[The GEnx is truly the first great engine of the 21st century,]
[based on the successful and proven architecture of the renowned GE90.]
