Frame 6FA 2nd Stage Bucket
Improved Design – Extending the Service Life of Your Parts
PW Power Systems (PWPS) has designed
a 2nd stage bucket for the Frame 6FA for
improved durability. The design incorporates
Pratt & Whitney ® high-temperature experience
to provide improved life-cycle costs.
The design addresses tip shroud curling
and cracking issues experienced in the
OEM configuration.

PW Power Systems™ Frame 6FA 2nd Stage
Blade Design Advantages Include
• Frame Gate Compatible
• Proprietary equiaxed alloy and proprietary metallic
coating system provide improved creep and oxidation life.
• Tip shroud 3D contouring removed and abradable coating
added on shroud to further improve shroud life survivability
to meet projected 72,000-hour cumulative life.
• Cooling distribution modified and peak temperature
reduced by cooling-hole optimization – helps in reducing
trailing-edge creep while not impacting total internal
cooling flow.
