Abstract
Official abstract text for this publication.
A turbine bucket assembly and turbine system are disclosed. The turbine bucket assembly includes a single-lobe joint having an integral platform, the joint having a first axial length; a segmented airfoil having a root segment extending radially outward from the platform and a tip segment coupled to the root segment, the tip segment having a second axial length, which is less than the first axial length; and a turbine wheel defining a receptacle with a geometry corresponding to the single-lobe joint and being coupled to the single-lobe joint. The tip segment includes a tip segment material, the root segment includes a root segment material, and the turbine wheel includes a turbine wheel material, the root segment material and the turbine wheel material having a lower heat resistance and a higher thermal expansion than the tip segment material.
First claim
Opening claim text (preview).
What is claimed is: 1. A turbine bucket assembly comprising: a single-lobe joint having a platform, the joint having a first axial length; a segmented airfoil having a root segment extending radially outward from the platform and a tip segment coupled to the root segment, the tip segment having a second axial length, the second axial length being less than the first axial length; and a turbine wheel defining a receptacle with a geometry corresponding to the single-lobe joint and being removably coupled to the single-lobe joint; wherein the tip segment includes a ceramic matrix composite, the root segment includes a titanium aluminide, and the turbine wheel includes a superalloy.
