摘要： An airfoil includes an exterior wall, a triple trailing edge pin bank, and first and second impingement systems. The exterior wall defines a first interior space. A segmenting wall divides the first interior space into a second and a first interior space. The first impingement system is disposed within the first interior space and the second impingement system is disposed within the first interior space. First impingement system includes impingement holes with a first impingement hole density. Second impingement system includes impingement holes with a second impingement hole density. The impingement systems also include dividing walls extending from a first and second interior wall to the exterior wall. The interior walls, exterior wall, and dividing walls define a first and second zone. The first and second impingement hole density is configured to separately meter flow to the first and second zones.

摘要： An airfoil for turbomachines includes a first plurality of projections coupled to a suction sidewall adjacent a trailing edge and extending from the suction sidewall towards a pressure sidewall. A second plurality of projections is coupled to the pressure sidewall adjacent the trailing edge and extending from the pressure sidewall towards the suction sidewall. The airfoil includes a divider coupled to the first and second pluralities of projections and extending within a space between the first and second pluralities of projections. A first cooling channel is defined adjacent the suction sidewall and a second cooling channel is defined adjacent the pressure sidewall. The first and second cooling channels are configured to receive a coolant stream. The first plurality of projections is configured to meter the coolant stream through the first cooling channel and the second plurality of projections is configured to meter the coolant stream through the second cooling channel.

The feed manifold is configured to receive a coolant stream therein and includes a plurality of feed plenums. The return manifold includes a plurality of return plenums. The sidewall defines a plurality of feed channels and a plurality of return channels therein. The sidewall further includes an inner surface and an outer surface opposite the inner surface. Each feed channel is in fluid communication with at least one of the feed plenums. Each return channel is in fluid communication with at least one of the return plenums. The sidewall further at least partially defines a plurality of microchannels. Each microchannel is in fluid communication with one of the feed channels and one of the return channels.

摘要： The present disclosure provides methods of defining internal secondary structures of an object to be formed at least in part by additive manufacturing. The object may include a primary structure having a volume. The methods may include applying a balancing parameter within an axis-aligned bounding box that encompasses the primary structure. The methods may further include refining the balancing parameter until the volume is delimited into a plurality of the internal structures. The plurality of internal structures may be oriented at an angle to a global z-axis that is substantially parallel to a build direction, such as angled in a range of 40 degrees to 70 degrees to the z-axis.

摘要： A turbine airfoil for a rotating blade or stationary nozzle vane includes an airfoil body including a leading edge and a trailing edge. A coolant supply passage extends within the airfoil body, and a coolant return passage extends within the airfoil body. A first trench is in an external surface of the airfoil body, the first trench extending to the trailing edge and being in fluid communication with the coolant supply passage. A second trench is in the external surface of the airfoil body, the second trench extending to the trailing edge and being in fluid communication with the coolant return passage and the first trench. A cover seats in the airfoil body and encloses the trenches to form coolant passages with the airfoil body. In embodiments, two coolant passages to and back from the trailing edge may be used to allow for a recycling flow.
