1. A gas turbine engine component comprising:
an airfoil including
an exterior pressure side;
a plurality of cooling holes located in the exterior pressure side along a trailing edge of the airfoil; and
a plurality of relief cuts surrounding a corresponding one of the plurality of cooling holes, wherein the plurality of relief cuts are elliptical and spaced from an adjacent relief cut of the plurality of relief cuts;
wherein the airfoil includes a leading edge cooling passage, an intermediate cooling passage, and a trailing edge cooling passage and the plurality of cooling holes are in fluid communication with the trailing edge cooling passage and the plurality of cooling holes are the downstream most cooling holes on the pressure side of the airfoil.
2. The component of claim 1 , wherein the plurality of cooling holes are in communication with an internal cooling passage in the airfoil and a perimeter of each of the plurality of relief cuts form a non-acute cross-sectional geometry with the exterior pressure side.
3. The component of claim 1 , wherein the plurality of relief cuts are spaced inward from opposing radial ends of the airfoil and is located upstream of the trailing edge.
4. The component of claim 1 , wherein the plurality of relief cuts are scalloped in cross section.
5. A combustor for a gas turbine engine comprising:
a combustor wall including:
an exterior pressure side surface;
an interior surface;
a plurality of cooling holes extending from the interior surface to the exterior pressure side surface, wherein the plurality of cooling holes extend through a thickness of the combustor wall;
an interior surface relief cut in the interior surface surrounding at least one of the plurality of cooling holes, wherein a perimeter of the interior surface relief cut forms a non-acute cross-sectional geometry with the interior surface; and
an exterior pressure side surface relief cut in the exterior pressure side surface surrounding the at least one of the plurality of cooling holes wherein a perimeter of the exterior pressure side surface relief cut forms a non-acute cross-sectional geometry with the exterior pressure side surface.
6. The combustor of claim 5 , wherein the plurality of cooling holes extend in a non-perpendicular direction relative to the exterior pressure side surface and the interior surface.
7. The combustor of claim 6 , wherein the interior surface relief cut is arranged in the combustor wall in a non-overlapping configuration with the exterior pressure side relief cut and the interior surface relief cut is separated from the exterior pressure side relief cut by a length of a corresponding one of the plurality of cooling holes.
