  • Patent number: 9145777
    Abstract: An article of manufacture has a first component configured for use with a turbomachine. The first component is configured for attachment to a second component, and reduces the possibility of attachment with an undesired third component by modification of a characteristic of the first component. This modification is matched by a complementary characteristic of the second component. The first component has a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in a scalable table selected from the group consisting of TABLES 1-11. Cartesian coordinate values of X, Y and Z are non-dimensional values convertible to dimensional distances by multiplying by a number. X and Y are coordinates which, when connected by continuing arcs, define airfoil profile sections at each Z height. The airfoil profile sections at each Z height being joined with one another to form a complete airfoil shape.

  • Patent number: 8714908
    Abstract: A method and system for improving performance of a compressor section of a gas turbine by diverting leakage air flowing from high pressure downstream of a stator vane assembly to low pressure upstream of the stator vane assembly from disrupting design flow patterns at a leading edge of stator vanes. A cover is provided at a forward face of an inner shroud assembly to prevent the leakage air from impinging on the leading edge. The cover may be provided at an outlet channel of a flow diverter mounted on the forward face of the inner shroud assembly.

  • Publication number: 20120240591
    Abstract: A method and apparatus for shutting down a generator to prepare the generator for restart is disclosed. A power down sequence of a gas turbine of the generator is initiated from an operating state. A purge gas is forced into the gas turbine to extinguish a combustion flame in the gas turbine. The purge gas is swept through the gas turbine to displace the fuel from the gas turbine using a coast down airflow through the gas turbine during the power down sequence to prepare the generator for restart.
