Abstract
The second stage buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z set forth Table I wherein X, Y and Z values are in inches. Z represents a distance in inches from and perpendicular to a plane passing through the engine centerline. X and Y are distances in inches which, when connected by smooth continuous arcs, define airfoil profile sections at each distance Z. The profile sections at the Z distances are joined smoothly with one another to form the complete airfoil shape. The X and Y distances and optionally the Z distance may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelop of ±0.016 inches.
