Publication number: 20230250724Abstract: 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, Table IV, Table V, Table VI, Table VII, Table VIII, or Table IX. 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: ApplicationFiled: March 29, 2023Publication date: August 10, 2023Inventors: Marc Edward Blohm, Vasantharuban S, Michael James Dutka, Nandakumar A R, Sharan Shanti, Prakash Dalsania, Corey Lynn Hubbert, Siddaraja Mallikarjuna Devangada, Joshy John, Nancy Chaudhary, Abel Christena Francis, Brandon Lamar Bush, Jeremy Peter Latimer

Publication number: 20180017074Abstract: This disclosure provides systems and methods for reducing stress in vane shroud assemblies by defining a gap between adjacent portions of the airfoil and the shroud whereby stress from the securing force is relieved in a portion of the shroud. The airfoil has a distal end with a contact surface and a tenon. The shroud has a contact surface with the airfoil and accommodates the tenon. An attachment device provides the securing force between the airfoil and shroud contact surfaces through the shroud and the gap serves to reduce stress on the shroud.Type: ApplicationFiled: July 13, 2016Publication date: January 18, 2018Inventors: Sharan Shanti, Nandakumar AR, Christian Michael Hansen, Jeremy Peter Latimer
