Abstract

A combustor heat shield (14) includes a wall (40, 42) bound by an inner surface (50) and an outer surface (52) spaced from the inner surface (50). The inner surface (50) bounds at least a portion of a combustion chamber (46). Effusion holes (68A, 68B) extend through the wall (40, 42) from the outer surface (52) to the inner surface (50) within a first zone (62) of the wall (40, 42) and a second zone (64) of the wall (40, 42) discrete from the first zone (62). The diameters (D1) of effusion holes (68A) within the first zone (62) are larger than diameters (D2) of effusion holes (68B) within the second zone (64).
