    摘要: A bimetallic ring for use as a turbine shroud in a gas turbine engine. The bimetallic ring forms a sealing surface as a hot gas flow path boundary in the engine. The ring is comprised of two materials. The first material, a wrought, oxidation resistant metal alloy comprises a first portion, which is the hot gas flow path sealing surface. The second material, a low cost low alloy steel, comprises a second portion that may be at least a pair of supporting side plates. A dissimilar weld joint joins the sealing surface to the second portion, the at least pair of supporting side plates.

    摘要: A turbine bucket assembly and turbine system are disclosed. The assembly includes a multi-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 less than the first axial length; and a turbine wheel defining a receptacle with a geometry corresponding to the multi-lobe joint and being coupled to the multi-lobe joint. A tip segment material, a root segment material, and a turbine wheel material are selected, such that the turbine wheel material and the root segment material have a lower heat resistance and a higher thermal expansion than the tip segment material.

    摘要: An aft clamp ring for a gas turbine engine is disclosed. The aft clamp ring includes a body, a forward sealing face, and an aft sealing face. The body includes an annular shape extending between an outer end and an inner end. The forward sealing face faces in a second axial direction. The aft sealing face is adjacent the outer end facing in a first axial direction and is at least partially radially aligned with the forward sealing face. The forward sealing face and the aft sealing face are each an annular surface with a surface area from 105.50 cm2 to 165.19 cm2.

    摘要: The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a first seal section and an uncoupled second seal section which allows the first and second seal sections to move relative to one another during relative movement between the two components. One or more spring tabs extend from the first seal section and/or the second seal section, are disposed between the first and second seal sections, and bias the first and second seal sections away from one another.
