Abstract
A blade for a gas turbine includes an outer surface, an inner surface that defines a cavity for receiving a gaseous cooling fluid, and a cooling hole foot formed on the inner surface. The cooling hole foot includes an first foot surface that extends inclined relative to a base surface region of the inner surface surrounding the cooling hole foot. A cooling hole extends between the first foot surface of the cooling hole foot and the outer surface to discharge cooling fluid from the cavity to the outer surface. A central axis of the cooling hole extending transverse to the first foot surface.
