<P>PROBLEM TO BE SOLVED: To provide airfoils for a vane of a gas turbine, specifically, compressor airfoil profiles for a Stage 4 rotor vane. <P>SOLUTION: An article of manufacture has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a table A (not shown). 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 can be joined smoothly with one another to form a complete airfoil shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
