Patent number: 8702384Abstract: A turbomachine component includes a compressor stator vane having an airfoil core shape. The airfoil core shape includes a nominal profile substantially in accordance with Cartesian coordinate values of X, Y, and Z set forth in TABLE 1, and wherein X and Y are distances in inches which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z in inches. The profile sections at the Z distances are joined smoothly with one another to form a complete airfoil core shape.Type: GrantFiled: March 1, 2011Date of Patent: April 22, 2014Assignee: General Electric CompanyInventors: Julianne Edna Baer, Umesh Garg

Publication number: 20130205795Abstract: A turbomachine includes a housing that defines a flow path, and a stage arranged within the housing. The stage includes a plurality of rotating airfoil members and a first plurality of stationary airfoil members. A second plurality of stationary airfoil members is arranged directly adjacent to the first plurality of stationary airfoil members. A flow improvement system is associated with each of the first and second pluralities of stationary airfoil members. The flow improvement system establishes a predetermined clocking of each of the first plurality of stationary airfoil members relative to each of the second plurality of stationary airfoil members to improve flow characteristics along the flow path.Type: ApplicationFiled: February 9, 2012Publication date: August 15, 2013Applicant: GENERAL ELECTRIC COMPANYInventors: Umesh Garg, Akil Abbas Rangwalla, Francesco Soranna, Lakshmanan Valliappan
