Patent number: 11401816Abstract: A rotor blade includes an airfoil having an airfoil shape. The airfoil shape has a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in one of Table I, Table II, Table III, or Table IV. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil in the unit of distance. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each Z value. The airfoil profile sections at Z values are joined smoothly with one another to form a complete airfoil shape.Type: GrantFiled: April 30, 2021Date of Patent: August 2, 2022Assignee: General Electric CompanyInventors: Paul G. Deivernois, Lauren Alexandra Schuhle, Michael James Dutka, Venkata Siva Prasad Chaluvadi, Corey Lynn Hubbert, Timothy E. Dejoris, Marcus Edward Blohm, Jeremy Peter Latimer

Patent number: 9145777Abstract: 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.Type: GrantFiled: July 24, 2012Date of Patent: September 29, 2015Assignee: General Electric CompanyInventors: Michael James Dutka, John Duong, Ya-Tien Chiu, Alexander David Shrum, Kelvin Rono Aaron, Christopher Edward LaMaster, San-Dar Gau, Franco Monteleone, Paul Griffin Delvernois, Matthew John McKeever, Govindarajan Rengarajan, Jeremy Peter Latimer, Marc Edward Blohm, Eric Richard Bonini, Venkata Siva Prasad Chaluvadi, Jamie Dean Lumpkin, Thomas Robbins Tipton

Patent number: 8714908Abstract: 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.Type: GrantFiled: November 5, 2010Date of Patent: May 6, 2014Assignee: General Electric CompanyInventors: Michael James Dutka, Venkata Siva Prasad Chaluvadi
