Abstract: A cooling assembly comprises a coolant source chamber inside an airfoil that directs coolant inside the airfoil that extends between a hub end and a tip end that includes a tip body and tip rail along a radial length. A first body cooling chamber and a second body cooling chamber are disposed inside the tip body. The second body cooling chamber is positioned between the tip end and the first body cooling chamber. At least one of the first or second body cooling chambers are fluidly coupled with the coolant source chamber. The coolant source chamber directs the coolant into the first or second body cooling chambers. A rail cooling chamber disposed inside of the tip rail is fluidly coupled with the first or second body cooling chambers. The first or second body cooling chambers directs coolant out of the body cooling chambers and into the rail cooling chamber.

Abstract: A cooling assembly comprises a pin disposed inside a first chamber of an airfoil. The first chamber is disposed inside the tip end comprising a tip floor. The pin extends from a first end to a second end along a pin axis. The first end is coupled with a first surface of the first chamber and the second end is coupled with an inner floor surface of the tip floor such that the pin increases a structural load support level of the tip floor. A cooling conduit is placed inside the pin through which coolant flows. The cooling conduit is elongated along and extends around a conduit axis and is fluidly coupled with conduit channels disposed between the first and second ends of the pin. The conduit channels direct coolant out of the cooling conduit or direct coolant into the cooling conduit.

Abstract: A cooling assembly includes a cooling chamber disposed inside of a turbine assembly. The cooling chamber directs cooling air inside an airfoil of the turbine assembly. The cooling assembly includes a metered channel fluidly coupled with the cooling chamber. The metered channel directs at least some of the cooling air out of the cooling chamber outside of a rail surface of the airfoil. The metered channel is elongated along and encompasses an axis. The metered channel has an interior surface with a distance between opposing first portions of the interior surface. The distance between the opposing first portions decreases at increasing distances along the axis from the cooling chamber toward the rail surface.
