Repaired or remanufactured blade platform for a gas turbine engine

1. An article of manufacture, the article having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE 1, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define profile sections at each distance Z in inches to form a portion of a rotor blade.

2. The article of manufacture as recited in claim 1 , wherein the portion of said rotor blade is a platform puck and a portion of a platform.

3. The article of manufacture as recited in claim 2 , wherein said platform puck is electrical discharge machined.

4. The article of manufacture as recited in claim 3 , wherein said platform puck is brazed to said platform.

5. The article of manufacture as recited in claim 4 , wherein said platform puck and said portion of a platform lies in an envelope within +/−.0.160 inches in a direction normal to any article surface location.

6. The article of manufacture as recited in claim 1 , wherein said nominal profile lies in an envelope within +/−.0.160 inches in a direction normal to any article surface location.

7. The article of manufacture as recited in claim 1 , wherein the Cartesian coordinate values of X, Y and Z set forth in TABLE 1 are scaled by a constant to provide a scaled-up or scaled-down profile.

8. The article of manufacture as recited in claim 7 , wherein said nominal profile lies in an envelope within +/−.0.160 inches in a direction normal to any article surface location.

9. The article of manufacture as recited in claim 1 , wherein the Cartesian coordinate values of Z set forth in TABLE 1 are scaled by a constant to provide a scaled-up or scaled-down profile.

10. A rotor blade having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE 1, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define profile sections at each distance Z in inches to form a platform puck brazed to a portion of a platform.

11. The rotor blade as recited in claim 10 , wherein said platform puck is electrical discharge machined.

12. The rotor blade as recited in claim 11 , wherein said platform puck is brazed to said platform.

13. The rotor blade as recited in claim 12 , wherein said platform puck and said portion of a platform lies in an envelope within +/−.0.160 inches in a direction normal to any article surface location.

14. The rotor blade as recited in claim 12 , wherein the Cartesian coordinate values of X, Y and Z set forth in TABLE 1 are scaled by a constant to provide a scaled-up or scaled-down profile.

15. The rotor blade as recited in claim 12 , wherein the Cartesian coordinate values of Z set forth in TABLE 1 are scaled by a constant to provide a scaled-up or scaled-down profile.

16. A rotor blade having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in TABLE 1, wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define profile sections at each distance Z in inches to form a platform puck brazed to a portion of a platform, the Cartesian coordinate values of X, Y and Z set forth in TABLE 1 are scaled by a constant to provide a scaled-up or scaled-down profile.

17. The rotor blade as recited in claim 16 , wherein said platform puck is electrical discharge machined.

18. The rotor blade as recited in claim 16 , wherein said platform puck is brazed to said platform.

19. The rotor blade as recited in claim 16 , wherein said platform puck is brazed to said platform only on a pressure side of said platform.

20. The rotor blade as recited in claim 16 , wherein said platform puck and said portion of a platform lies in an envelope within +/−.0.160 inches in a direction normal to any article surface location.
