Abstract
Proposed are an airfoil, a turbine blade including the airfoil, and a gas turbine including the turbine blade. The airfoil includes a suction side having an outwardly convex surface, a pressure side having a concave surface toward the suction side, a leading edge connecting the suction side and the pressure side and defining a front end of the airfoil, a trailing edge connecting the suction side and the pressure side and defining a rear end of the airfoil, a cooling flow passage configured to guide cooling fluid introduced from a lower portion of the suction side and the pressure side, to one or more flow channels respectively at the suction side and the pressure side, and then discharge the cooling fluid to a region rearward of the trailing edge, and a flow guide part provided in each of the one or more flow channels and forming a cooling space.
