<p>A turbine bucket (10) is provided and includes a shank (20) defining a cavity (22) therein, which is connectible with a rotor such that wheelspace air (40) having an initial pressure is permitted to flow into the cavity (22) and a platform (30) coupled to the shank (20) and defining a cooling hole (50, 60) therein, the shank (20) and the platform (30) each further defining the cavity (22) and the cooling hole (50, 60), respectively, as being fluidly communicative with one another, such that the wheelspace air (40) permitted to flow into the cavity (11) is deliverable from the cavity (22) and through the cooling hole (50, 60) at a second pressure greater than the initial pressure.</p> |
