More Information
Summary:Disclosed herein are an airfoil, and a turbine blade and gas turbine including the same. The airfoil includes a first cooling passage allowing a first cooling fluid introduced from the bottom of a leading edge to flow into a first serpentine channel formed on a pressure side, and to be then discharged to the rear of a trailing edge, and a second cooling passage allowing a second cooling fluid introduced from the bottom of a suction side to be divided and flow into at least two second serpentine channels formed on the suction side, and allowing the divided cooling fluids introduced into the at least two second serpentine channels to be joined at the bottom thereof and to be then discharged to the rear of the trailing edge.
