In Excess of 2 Million Hours of Successful Operational Runtime Experience on “F” Class Hardware. Frame 7FA.03 1st, 2nd, 3rd Stage Buckets Improved Design – Extending the Service Life of Your Parts PW Power Systems (PWPS) designs the rotating components for the hot gas path of the Frame 7FA.03 gas turbine. The designs incorporate extensive high-temperature experience to provide improved total life-cycle costs. PWPS improves upon the OEM offering by leveraging Pratt & Whitney® designed parts to minimize oxidation, creep and metal temperature, ultimately extending part life and reducing operating costs. PW Power Systems Frame 7FA.03 1st Stage Bucket Design Advantages Include: • Directionally solidified proprietary alloy and proprietary UDC Thermal Barrier Coating (TBC) system provide improved creep resistance and oxidation life ™ • Improved cooling distribution reduces peak metal temperature • T railing edge undercut to alleviate trailing-edge cooling-hole cracking • Cooled platform to resolve cracking for high-hour and starts (corner box operationing users) PW Power Systems Frame 7FA.03 2nd Stage Bucket Design Advantages Include: • Proprietary equiaxed alloy and proprietary TBC system provide improved creep resistance and oxidation life ™ • Tip shroud 3D contouring with cutter tooth removed and abradable coating added on shroud rail to further improve shroud life to meet 72,000-hour cumulative life • Improved cooling distribution and peak temperature reduction through additional trailing-edge cooling holes reducing trailing-edge creep while not changing total internal cooling flow PW Power Systems Frame 7FA.03 3rd Stage Bucket Design Advantages Include: • Proprietary equiaxed alloy and chromide coating system provide improved creep resistance and corrosion life ™ • Tip shroud 3D contouring with cutter tooth removed and abradable coating added on shroud rail to further improve shroud life to meet 72,000-hour cumulative life
