Claim 0:
1. 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; and
a set of cooling holes, each cooling hole of the set of cooling holes comprising a passage extending between an inlet at the cooled surface and an outlet at the heated surface, the passage defining a centerline forming a first angle (θ) with the heated surface, the passage having a top wall and a bottom wall each extending from the inlet toward the outlet, and a layback surface defining at least a portion of the outlet, extending from the bottom wall to the heated surface, the layback surface forming a second angle (β) with the bottom wall and a third angle (Δ) with the heated surface;
wherein for any range of angle values (α): (αlow<α<αhi):
for at least a first cooling hole of the set of cooling holes αhi+αlow<θ, and αlow<Δ<αhi; and
for at least a second cooling hole of the set of cooling holes αhi+αlow >θ, and αlow<β<αhi.
