A topping cycle fuel cell unit includes a support plate having internal flow passages that extend to combustion outlets, a first electrode layer, an electrolyte layer, and a second electrode layer. The second electrode layer is configured to be coupled to another support plate of another fuel cell unit. The internal flow passages are configured to receive and direct air across the first electrolyte layer or the second electrolyte layer and to receive and direct fuel across another of the first electrolyte layer or the second electrolyte layer such that the first electrode layer, the electrolyte layer, and the second electrode layer create electric current. The internal flow passages are configured to direct at least some of the air and at least some of the fuel to the combustion outlets where the at least some air and the at least some fuel is combusted.

Integrated fuel cell and combustion system

A method of forming a directionally-solidified casting component using a casting system is provided. The casting system includes a chamber having a heating zone and a cooling zone separated by a baffle plate. The method includes pouring an alloy in a liquid state into a mold shell. The mold shell is positioned on a chill plate within the heating zone. The method further includes moving the mold shell from the heating zone into the cooling zone. The alloy transfers from the liquid state to a solid state within the mold shell while moving the mold shell from the heating zone to the cooling zone. The method further includes contacting the mold shell with a heat transfer member.

Heat extraction or retention during directional solidification of a casting component

An additive manufacturing system includes a build platform, a particulate dispenser assembly configured to dispense or remove particulate to or from the build platform, and a plurality of print heads each having at least one binder jet. The binder jets are configured to dispense at least one binder in varying densities onto the particulate in multiple locations to consolidate the particulate to form the component with a variable binder density throughout. The system also includes a plurality of arms extending at least partially across the build platform and supporting the print heads and at least one actuator assembly configured to rotate the print heads and/or the build platform about a rotation axis and move at least one of the print heads and the build platform in a build direction perpendicular to the build platform as part of a helical build process for the component.

Additive manufacturing systems and methods including rotating binder jet print head

An airfoil includes a multi-part body and one or more thermally conductive pins. The multi-part body has an interior region and is formed from multiple pieces joined with each other at an interface. The pieces have multiple cavities and at least one of the pieces defines airfoil cooling channels disposed within the interior region of the body. The one or more thermally conductive pins are within the interior region of the body and extend across the interface. Each of the thermally conductive pins has a first segment disposed within a corresponding cavity of a first piece of the multiple pieces and a second segment disposed within a corresponding cavity of a second piece of the multiple pieces.

Airfoil with thermally conductive pins

Methods and systems for fabricating a component by consolidating a particulate include a build platform configured to receive a particulate, a particulate dispenser configured to deposit the particulate on the build platform, and at least one print head including at least one jet. The at least one print head is configured to dispense a binder through the at least one jet onto the particulate to consolidate at least a portion of the particulate and form a component. The methods and systems also include at least one actuator assembly configured to rotate at least one of the at least one print head and the build platform about a rotation axis extending through the build platform and move at least one of the at least one print head and the build platform in a build direction perpendicular to the build platform as part of a helical build process for the component.
