Article of manufacture

An article of manufacture comprising:

• a first component configured for use with a turbomachine, the first component configured for attachment to a second component, the first component having a neck width, a platform length, a platform angle, a platform height, a tang height, a tang depth and a dovetail circumferential width, wherein the first component is configured to substantially reduce the possibility of attachment with an undesired third component by modification of at least one characteristic of the first component, so that the modification of the at least one characteristic is matched by a complementary characteristic of the second component, the at least one characteristic comprising at least one of, the neck width, the platform length, the platform angle, the platform height, the tang height, the tang depth and the dovetail circumferential width;
• wherein the first component has a suction-side nominal airfoil profile substantially in accordance with suction-side Cartesian coordinate values of X, Y and Z set forth in a scalable table, the scalable table selected from the group of tables consisting of TABLES 1-11, wherein the Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying the Cartesian coordinate values of X, Y and Z by a number, and wherein 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 suction-side airfoil shape, the X, Y and Z coordinate values being scalable as a function of the number to provide at least one of a non-scaled, scaled-up and scaled-down airfoil profile;
• and
• the suction-side airfoil shape lies in an envelope within at least one of, +/−5% of a chord length in a direction normal to a suction-side airfoil surface location, or +/−0.25 inches in a direction normal to a suction-side airfoil surface location.
