LP TURBINE VANE AIRFOIL PROFILE

摘要

A single stage low pressure turbine vane 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 of sections 5 to 10 set forth in Table 2. 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 airfoil profile addresses aerodynamic issues peculiar to simple stage low pressure turbine vanes.
