  • Turbine exhaust strut airfoil profile
    Patent number: 7559747
    Abstract: A turbine exhaust thin strut includes an airfoil section 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.
    Type: Grant
