Embodiment Construction

[0025] Reference will now be made in detail to various embodiments of the invention, one or more examples of which are illustrated in the drawings. The detailed description uses numerical and letter designations to refer to features in the drawings. The same or similar symbols in the drawings and descriptions are used to refer to the same or similar parts in the present invention. The terms "first", "second" and "third" used in this specification may be used interchangeably to distinguish different components, and these terms are not intended to indicate the position or importance of each component. The terms "upstream" and "downstream" refer to relative directions with respect to fluid flow in a fluid pathway. For example, "upstream" refers to where the fluid flow is coming from, while "downstream" refers to the direction the fluid flow is going. The term "radial" refers to a relative direction that is substantially perpendicular to the axial centerline of a particular comp...

Abstract

A turbine blade comprises a cooling passage defined between a pressure side wall and a suction side wall. A pin is disposed within the cooling passage and includes a first end that is connected to the pressure side wall and a second end that is connected to the suction side wall. A radially oriented fillet having a maximum radius of curvature value is disposed along a periphery of at least one of the first end or the second end within a region of peak steady state stress. An axially oriented fillet having a maximum radius of curvature value is disposed along a periphery of at least one of the first end or second end within a region of peak vibratory stress. The maximum radius of curvature value of the axially oriented fillet is greater than the maximum radius of curvature value of the radially oriented fillet.

Description

technical field [0001] The present invention generally relates to a turbine blade for a gas turbine. In particular, the present invention relates to a turbine blade having pins arranged in an array of pin sets and a method for enhancing the mechanical performance of the turbine blade. Background technique [0002] The turbine section of a gas turbine typically includes rows or stages of turbine blades connected to a rotor shaft. The first row of stationary buckets may be disposed at the turbine section inlet upstream of the first row of turbine blades. Subsequent rows of stator buckets are disposed within the turbine section between subsequent rows of turbine blades. A casing surrounds each row of fixed buckets and turbine blades to define a high temperature gas passage through the turbine section. In operation, high temperature combustion gases pass through the first row of stationary buckets and the high temperature gas passages defined within the turbine section. Ther...
