Abstract: A gas turbine engine component is described. The component includes a component wall (102) having an internal surface (106) that is adjacent a flow of coolant and an external surface (104) that is adjacent a flow of gas. The component wall (102) includes a cooling hole (100) that has an inlet (108) defined by the internal surface (106) and an outlet (110) defined by the external surface (104). The cooling holes (100) also has a metering location (122) having the smallest cross-sectional area of the cooling hole (100), an internal diffuser (112) positioned between the inlet (108) and the metering location (122), an accumulation diverter portion of the internal diffuser (112) and an accumulator portion of the internal diffuser (112).

Abstract: A gas turbine engine component (100; 200; 300) includes a body (120) with a wall (122) surrounding an interior cavity (124). The wall has opposed interior (126; 226; 326) and exterior surfaces (128; 228). The interior surface has a plurality of coolant inlets (142, 144; 242, 244, 247; 342, 344, 347) and the exterior surface has a coolant outlet (140; 240; 340) defined therein. A coolant conduit (80) extends between the coolant inlets and the coolant outlet and is configured and adapted to induce secondary flow vortices in coolant traversing the coolant conduit and in an adherent coolant film over a portion of the exterior surface of component body.

Abstract: A gas turbine engine component includes a wall (94) that provides an exterior surface (79) and an interior flow path surface (96). A film cooling hole (92) extends through the wall (94) and is configured to fluidly connect the interior flow path surface (96) to the exterior surface (79). The film cooling hole (92) has a pocket (100) that faces the interior flow path (96) and extends substantially in a longitudinal direction. The film cooling hole (92) has a portion downstream from the pocket (100) and is arranged at an angle (120) relative to the longitudinal direction and extends to the exterior surface (79).
