Claim:
1. An apparatus comprising: a shape operable as a gas turbine engine component; an internal cavity within the shape including a radius; a trench on an external surface of the shape including a rear face tangential to an arc centered on the radius of the internal cavity; and a cooling hole extending from the internal cavity and exiting to the trench through the rear face of the trench, wherein a cooling fluid introduced to the internal cavity flows through the cooling hole and into the trench during operation of the gas turbine engine component, the rear face extends to a point spaced a first distance from a suction sidewall defined by the external surface of the shape, the cooling hole is spaced a second distance from the suction sidewall greater than the first distance, and the rear face of the trench is centered on a centerline of the radius of the internal cavity.
