HP TURBINE VANE AIRFOIL PROFILE

摘要

A high 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 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 design of the airfoil equalizes the static pressure gradient in the spanwise direction. This allows to minimize secondary losses.
