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
    (margin CAEP/6)

Growth

Runway for growth

Powered by proven geared architecture – and more than 40 industry leading innovations – the Pratt & Whitney GTF is unlike any engine that’s come before it. With pioneering technology that enables further evolution and performance enhancements in the future, the GTF is truly in a league of its own.
