Airfoil shape for a turbine bucket

摘要

The bucket (16) has a bucket airfoil (36) comprising a nominal profile with Cartesian coordinate values of X, Y, and Z. The Z values are convertible to Z distances by multiplying the Z values by a height of the airfoil. X and Y are distances which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections are joined smoothly to form a complete airfoil shape. An independent claim is also included for a turbine comprising a turbine wheel.
