Embodiment Construction

[0035] One or more specific aspects / embodiments of the invention are described below. In an effort to provide a precise description of these aspects / embodiments, not all features of an actual implementation may be described in the specification. It should be recognized that in developing any practical implementation, such as in any engineering or design project, implementation-specific decisions must be made in order to achieve the specific goals of the person developing it, such as compliance with mechanical-related, system-related and business-related constraints, which may vary from implementation to implementation. Furthermore, it should be appreciated that making such an implementation would be extremely complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and production for those of ordinary skill in the art having the benefit of this disclosure.

[0036] When introducing elements of various embodiments of the invention, th...

Abstract

An article of manufacture has a first component configured for use with a turbomachine. The first component is configured for attachment to a second component, and reduces the possibility of attachment with an undesired third component by modification of a. characteristic of the first component. This modification is matched by a complementary characteristic of the second component. The first component has a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table selected from the group consisting of TABLES 1-11. Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying by a number. X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height. The airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.

Description

technical field [0001] The present invention relates generally to turbomachines, and more particularly to articles configured for use in turbomachines. Background technique [0002] In a turbine, each stage of the turbine flow path should meet a number of system requirements to meet the design goals. These design goals include, but are not limited to, increased overall efficiency, reduced vibrational response, and improved airfoil loadability. For example, the compressor airfoil profile should meet the thermal and mechanical operating requirements of a particular stage of the compressor. In addition, component life, reliability and cost targets should be met. [0003] When turbine components are initially assembled or subsequently repaired and replaced, a large number of components must be installed in specific locations on the turbine. For example, the stage 1 rotor blades must be installed in the correct position on the stage 1 rotor wheel. A typical turbine may includ...
