ABSTRACT:
A combustion turbine20includes a housing22and a plurality of airfoils40within the housing. Each airfoil40has a leading edge surface42and at least one interior cooling passageway44. A plurality of diffusion holes46extend from the at least one interior cooling passageway44to the leading edge surface42. Each diffusion hole46includes a proximal section48having a generally constant cross-sectional shape and a distal tapered section50that extends outwardly from the proximal section, tapering in a radially inward direction.
