PROBLEM TO BE SOLVED: To provide a turbine airfoil-sidewall integrated bucket. SOLUTION: The bucket (700) includes an airfoil (770) that accounts for a radial variation of the inlet flow angle for working fluid (750, 755) with the boundary layer of a flow adjacent to an inner sidewall (701) and an outer sidewall (703). Local chamfering of the airfoil (770) in regions (707, 708) of the sidewalls (701, 703) provides the airfoil and fillets (705, 706) with shapes for efficiently accommodating the radial distribution of the inlet flow angle for the working fluid in the sidewall regions.
