Patent number: 11519273Abstract: 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: GrantFiled: July 16, 2021Date of Patent: December 6, 2022Assignee: General Electric CompanyInventors: Michael James Healy, Matthew John McKeever, Sabarinath Devarajan, Uday Krishna Pappala, Kevin Michael Barnett, Kumaran Vale Mudaliar, Wilfried Rick, Moorthi Subramaniyan, Karan Ghule, Denis Stankovic, Yu Wang, Marco Micheli, Mariadas Anton Charles Anandarajah, Michael Loetzerich

Patent number: 10781825Abstract: A system is provided, including an airfoil. The airfoil includes a first suction portion of a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of a suction side as set forth in TABLE I to a maximum of three decimal places, wherein the X and Y values of the suction side are coordinate values that couple together to define suction side sections of the first suction portion of the nominal airfoil profile at each Z coordinate value, the suction side sections of the first suction portion of the nominal airfoil profile are coupled together to define the first suction portion, the airfoil includes an airfoil length along a Z axis, the first suction portion comprises a first portion length along the Z axis, the first portion length is less than or equal to the airfoil length, and the Cartesian coordinate values of X, Y, and Z are non-dimensional values convertible to dimensional distances.Type: GrantFiled: September 28, 2018Date of Patent: September 22, 2020Assignee: General Electric CompanyInventors: Matthew John McKeever, Vasantharuban Subramanian, Mariadas Anton Charles Anandarajah, Yingbin Bao, Derek Paul Columbus
