PROBLEM TO BE SOLVED: To provide an airfoil having a cooling hole with a flag region.SOLUTION: The airfoil (10) is provided and includes a body (20) formed to define the substantially radially extending cooling hole (30) therein, which is configured to be receptive of a supply of a coolant (11) for removing heat from the body (20), and the flag region (40) therein, which is fluidly communicative with the cooling hole (30) and thereby configured to be receptive of a portion of the supply of the coolant (11) such that coolant portion is directed to form a vortex within the flag region (40) to increase heat removal from the body (20) beyond that provided by the coolant flow through the cooling hole (30). |
