Architecture
Fan
Big fan, even bigger benefits.
This aerodynamic marvel: a bigger, more efficient fan brings you a quieter engine and the highest bypass ratio in commercial aviation.
- Up to 81” fan diameter
- Up to 12:1 bypass ratio
Optimization
Speed matters
A slow fan and a fast core mean peak performance with no compromises – each part runs at its optimum speed.
- 40% slower fan speed
(compared to previous generation engines) - 2,000 airfoils eliminated
FDGS
Geared for tomorrow, today
Fan Drive Gear System (FDGS)
A fundamental shift in jet engines, seven moving parts unlock high performance through a proven geared architecture.
- 3:1 gear ratio
- 5M+ hours of operation
Compressors
It’s what’s inside that counts
Compressing air is hard work. That’s why the GTF engine shares the load effectively between its high and low pressure spools. Its integrally bladed rotors (IBRs) innovatively increase efficiency.
- 60% higher pressure ratio
(compared to previous generation engines) - Up to 2 fewer stages
Turbines
Fewer stages, more to love
Lightweight and green. High-speed turbines coated with the latest in material technology can operate in extreme temperatures. Along with a simplified combustor, the result is optimum efficiency and cleaner skies.
- Up to 4 fewer turbine stages
(compared to current generation engines) - Up to 50% reduction in regulated NOx emissions
