Compressor

  Performance

• 3D aerodynamic airfoils - an advanced aviation-style high-efficiency, 14-stage compressor that increases airflow and robustness

  Operability

• Inlet guide vanes - three variable stator vane stages with additional variable geometry stages that enhance operability and flexibility

  Maintainability

• Field replaceable blades - reduced outage times for improved availability
• Improved borescope access - additional borescope port locations to enhance inspection capability
• Blade health monitoring - prognostic system to enable early detection of blade characteristic changes

Combustor

  Experience

• DLN 2.6 combustor – proven combustion system with more than 14 million hours of service and 380,000 starts

Turbine

  Performance

• Hot gas path evolution - builds upon 7FA and 7FB experience to provide improved output and efficiency
• Low emissions – single digit NOx and CO emissions across entire operating range

  Durability

• FB materials – proven materials used in a less severe environment (lower firing temperature)
