A high-temperature component including a plurality of cooling passages through which the cooling medium can flow, a header connected to respective downstream ends of the plurality of cooling passages, and one or more outlet passages for discharging the cooling medium flowing into the header to outside of the header. The one or more outlet passages are less in number than the plurality of cooling passages. Respective minimum flow passage cross-sectional areas of the one or more outlet passages are not less than respective flow passage cross-sectional areas of the plurality of cooling passages in a connection between the header and the cooling passages. A sum of the respective minimum flow passage cross-sectional areas of the one or more outlet passages is less than a sum of the respective flow passage cross-sectional areas of the plurality of cooling passages in the connection between the header and the cooling passages.

A method for manufacturing an integrally formed bladed disk of a turbomachine, includes manufacturing a plurality of blades, the blades including a root and a profiled portion; and spark plasma sintering the blades with a metal powder, the blades being angularly distributed over a contour of an annular spark plasma sintering mold, the root of the blades being embedded into the metal powder, the profiled portion of the blades protruding from the metal powder radially outwardly.

Provided is a gas turbine vane and blade assembly in which lattice structures are installed between an impingement plate and an effusion plate. The gas turbine vane and blade assembly is capable of enhancing cooling efficiency in an impingement/effusion cooling technique.

In addition, the gas turbine vane and blade assembly can be manufactured using an additive manufacturing technique, and the lattice structures are capable of replacing supports that are used during an additive manufacturing process, and improving not only structural rigidity and stability but also cooling performance.

An electric machine includes a plurality of printed layers arranged to form a stator having an outer periphery and teeth extending radially inward from the outer periphery. Each of the printed layers includes discrete portions of metal and discrete portions of insulation. The discrete portions of insulation define a contiguous network of insulative boundaries separating discrete cells formed by the discrete portions of the metal. A volume of the discrete cells within the outer periphery is greater than a volume of the discrete cells within the teeth such that a reluctance of the teeth is greater than a reluctance of the outer periphery.
