Claim 12:
13. A component for a turbine engine which generates a hot gas fluid flow, and provides a cooling fluid flow, comprising:
a wall separating the hot gas fluid flow from the cooling fluid flow and having a heated surface along which the hot gas fluid flow flows and a cooled surface facing the cooling fluid flow;
a first pair of cooling holes, each cooling hole comprising a first inlet located at the cooled surface and a first outlet located at the heated surface, the first outlet comprising a modified outlet shape including a constant section,
a second pair of cooling holes located downstream from the first pair of cooling holes, each cooling hole comprising a second inlet located at the cooled surface beneath the first outlet and a second outlet located at the heated surface, the second outlet comprising the modified outlet shape;
wherein the constant section enables tight spacing of the first and second pair of cooling holes with respect to each other; and
wherein the first and second pair of cooling holes together form a patterned layout.
