Patent ID: 10704392

Abstract:
A turbine rotor blade including an airfoil, tip shroud, and fillet formed therebetween. The fillet defines a fillet profile variable about the intersection for connecting the tip shroud and airfoil and facilitating aerodynamic airflow. The fillet includes a pressure side fillet. The pressure side fillet comprises a pressure side fillet profile per points within a first set of points of X, Y and Z coordinate values in a Cartesian coordinate system, as set forth in Table I, where X, Y and Z are distances in inches from an origin and, when the points are connected by smooth, continuing arcs, the points define the pressure side fillet profile of the pressure side fillet. The first set of points includes points between and including point 1 and point 50 of each reference plane between and including a reference plane H and a reference plane W, as set forth in Table I.
