    摘要： A turbine bucket may generally include an airfoil formed from a metal-based material. The airfoil may include a base and a tip disposed opposite the base. The airfoil may also include a pressure side wall and a suction side wall extending between a leading edge and a trailing edge. Additionally, the turbine bucket may include a tip cap disposed between the pressure side wall and the suction side wall. The tip cap may be formed from a ceramic matrix composite material.

    摘要： A cooling system for use in regulating a temperature of a component is described herein. The cooling system includes a plurality of flow control assemblies that are defined across a sidewall of the component for channeling a cooling fluid across a surface of the sidewall. The plurality of flow control assemblies are configured to adjust a plurality of fluid flow characteristics of the cooling fluid. The plurality of flow control assemblies includes a first flow control assembly configured to adjust a first fluid flow characteristic, and at least a second flow control assembly configured to adjust a second fluid flow characteristic that is different than the first fluid flow characteristic.

    摘要： A method of controlling a power plant that includes a working fluid and a recirculation loop, wherein the power plant includes a combustion system having an upstream combustor operably connected to a high-pressure turbine and a downstream combustor operably connected to a low-pressure turbine. The method includes: recirculating the working fluid through the recirculation loop; controlling a compressed oxidant amount supplied to the upstream combustor and the downstream combustor; controlling a fuel amount supplied to the upstream combustor and the downstream combustor; controlling the power plant such that each of the upstream combustor and the downstream combustor periodically operates at a preferred stoichiometric ratio; and selectively extracting the working fluid from a first extraction point associated with the upstream combustor and a second extraction point associated with the downstream combustor based upon which combustors operates at the preferred stoichiometric ratio.

    摘要： A turbomachine includes a housing including a fluid path, and a first stage arranged within the housing. The first stage includes a first plurality of airfoil members and a second plurality of airfoil members. A second stage is arranged within the housing relative to the first stage. The second stage includes a third plurality of airfoil members and a fourth plurality of airfoil members. A flow improvement system is associated with each of the first and second stages. The flow improvement system establishes a predetermined clocking of each of the first plurality of airfoil members relative to corresponding ones of each of the third plurality of airfoil members, and each of the second plurality of airfoil members relative to each of the fourth plurality of airfoil members. The predetermined clocking is configured and disposed to improve flow characteristics along the flow path.
