Abstract
A component comprises a set of thin film cooling holes formed therein. Each of the thin film cooling holes provides a passage between a first surface of the component and a second surface of the component. Each of the thin film cooling holes includes a smooth transition between the first surface of the component and the surface the passage, and a progressively steeper flow path relative to the first surface of the component and between the smooth transition and the second surface of the component.
