Title: TURBOMACHINE COMPONENT, PARTICULARLY A GAS TURBINE ENGINE COMPONENT, WITH A COOLED WALL AND A METHOD OF MANUFACTURING
Abstract:
The invention is directed to a turbomachine component (10), particularly a gas turbine engine component, comprising at least one part (2) built in parts from a curved or planar panel (11), particularly a sheet metal, the part (2) comprising a plurality of cooling channels (3) via which a cooling fluid (5), particularly air, is guidable, wherein at least one of the plurality of cooling channels (3) has a continuously tapered section (8). The at least one of the plurality of cooling channels (3) has a single inlet port (1) from a first surface (15) of the panel (11) and a single outlet port (7) for the cooling fluid (5) to another surface (16), particularly a surface opposite to the first surface (15), or to the first surface (15). Further the panel (11) is built via laser sintering or laser melting or direct laser deposition. The invention furthermore is directed to a gas turbine engine equipped with such a component and a method of manufacturing.
