ABSTRACT:
A metered cooling slot disposed in a wall comprising an outer surface that is exposed to a hot gas stream and an inner surface that defines an internal coolant chamber through which a coolant passes, the metered cooling slot comprising: a slot formed within the outer surface elongated in a first direction, the slot comprising a pair of spaced apart, opposing, slot surfaces and a base, the slot surfaces intersecting the outer surface to form a slot outlet opposite the base; and two or more metering apertures formed within the wall, each metering aperture intersecting the inner surface of the wall to form a metering aperture inlet and intersecting one of the pair of slot surfaces to form a metering aperture outlet; wherein: D represents the approximate diameter of at least two of the metering apertures; P represents the approximate distance between the center lines of at least two neighboring metering apertures; and P/D comprises a value within the range of about 4 to 6.
