Patent number: 10533440Abstract: The present application provides a turbine nozzle including an airfoil shape. The airfoil shape may have a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances in inches by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in inches. The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The airfoil profile sections at Z distances may be joined smoothly with one another to form a complete airfoil shape.Type: GrantFiled: May 15, 2017Date of Patent: January 14, 2020Assignee: GENERAL ELECTRIC COMPANYInventors: Lee Larned Brozyna, Daniel Robert Burnos, Pradeep Ghute

Publication number: 20150110617Abstract: A turbine blade can include a root configured to connect to a turbine and supporting an airfoil configured to extend into a flowpath of the turbine. The airfoil can include a tip disposed substantially opposite the root and a first tip fillet disposed proximate the tip that can extend substantially perpendicular to a local flow direction at points along a surface of the turbine blade over the extremity of the first tip fillet. The tip fillet can enhance performance of the turbine by beneficially altering flow through a stage in which the blade is included.Type: ApplicationFiled: October 23, 2013Publication date: April 23, 2015Applicant: General Electric CompanyInventors: Alexander Stein, Lee Larned Brozyna, Mark Andrew Jones
