COMPRESSOR TURBINE BLADE AIRFOIL PROFILE

摘要

A turbine blade includes an airfoil having a profile substantially in accordance with at least an intermediate portion of the Cartesian coordinate values of X, Y and Z set forth in Table 1. The X and Y values are distances, which when smoothly connected by an appropriate continuing curve, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape. The profile of the blade has a trailing edge cutback in the tip end portion of the blade and an increasing thickness on the pressure side from mid span down to the blade platform.
