Abstract:
A gas turbine engine component includes a wall that provides exterior and interior surfaces. The interior surface faces an internal cooling passage of the gas turbine engine component. An aperture extends through the wall and interconnects the interior and exterior surfaces to one another and is configured to provide a cooling fluid from the cooling passage to the exterior surface. The aperture has first and second outlet holes overlapping one another at an intersection to provide opposing sharp corners at the intersection.
