Abstract
A turbine blade includes an airfoil having a root, tip cap, and laterally opposite pressure and suction sides extending between leading and trailing edges. A cooling circuit is disposed inside the airfoil and extends from the tip cap to the root for circulating a coolant. The airfoil also includes a pair of squealer tips extending radially upwardly from the tip cap along the pressure and suction sides which are spaced apart from the leading to trailing edges to define an upwardly open tip cavity. A thermal conductor is fixedly joined to the squealer tips and extends radially inwardly to the tip cap for conducting heat thereto for removal by the coolant. The conductor preferably surrounds the tip cavity inboard of the squealer tips and is coextensive therewith for being protected thereby.
