A cooling assembly comprises a cooling cavity disposed inside of a turbine assembly. The cooling cavity is configured to direct cooling air inside a body of the turbine assembly. The cooling assembly comprises a cross-bank fluidly coupled with the cooling cavity and positioned to direct at least some of the cooling air out of the cooling cavity and outside of the body. The cross-bank comprises plural pins having first ends coupled with a first side interior surface of the body and opposite second ends coupled with a second side interior surface of the body. The cross-bank also includes a cross-bar connecting the pins. The cross-bar extends between the pins such that the cross-bar has a first end coupled with an exterior surface of a first pin of the pins and an opposite second end coupled with an exterior surface of a second pin of the pins.

Cooling assembly for a turbine assembly

An assembly comprises a first cooling cavity disposed within one or more of a turbine assembly or a combustion chamber of an engine. The first cooling cavity directs cooling air within the one or more of the turbine assembly or the combustion chamber. The assembly comprises a second cooling cavity also disposed within the one or more of the turbine assembly or the combustion chamber. The second cooling cavity receives at least some of the cooling air from the first cooling cavity. A forward facing step nozzle forms a channel that fluidly couples the first cooling cavity with the second cooling cavity. The step nozzle includes steps having elongated first sides and narrow second sides. The elongated first sides of the steps protrude into the channel such that a cross-sectional area of the channel of the step nozzle at the steps is smaller than a cross-sectional area of the channel of the step nozzle outside of the steps.
