COMPONENT FOR A GAS TURBINE ENGINE WITH COATING OCCLUSION RESISTANT EFFUSION COOLING HOLES

A coating occlusion resistant effusion cooling hole (300) to form a film of a cooling fluid on a surface of a wall (308). The cooling hole extends along a longitudinal axis (LA). The cooling hole includes an inlet section (310) defined so as to be spaced apart from the surface. The inlet section is to receive the cooling fluid. The cooling hole includes a metering section (316) fluidly coupled downstream of the inlet section. The cooling hole includes an outlet section (318) fluidly coupled downstream of the metering section. The outlet section includes an overhang portion (348) , a recessed portion (350,352), a first sidewall (354) and a second sidewall (356). The first sidewall and the second sidewall interconnect the overhang portion with the recessed portion along a portion of the outlet section, and the first sidewall and the second sidewall converge and diverge in a plane transverse to the longitudinal axis.
