An article of manufacture having a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a table. Wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches, the profile sections at the Z distances being joined smoothly with one another to form a complete airfoil shape.

A method facilitates the assembly of a turbine engine. The method includes providing a shroud support block having a forward end and an aft end, coupling a forward end of a shroud to the shroud support block using a forward fastener, and coupling an aft end of the shroud to the shroud support block using an aft fastener. The method also includes installing a locking pin through the aft fastener to retain the aft fastener, and staking the locking pin in the shroud support block, such that the locking pin is securely coupled to the shroud support block.

Methods and apparatus for assembling turbine engines

The cooling system for the nozzle edges includes a chamber containing a cooling medium. First and second elongated plenums are disposed along opposite side edges of each platform. Inlet passages communicate cooling medium from the chamber into each plenum. Outlet passages from each plenum terminate in outlet holes in the side edges of the platform to cool the gap between adjacent nozzle segments. Passageways communicate with each plenum and terminate in film cooling holes to film cool platform surfaces. In each plenum, the inlet passages are not in direct line-of-sight flow communication with the outlet passages and passageways.
