More Information
Summary:A turbine engine airfoil (34) includes an airfoil structure having an exterior surface (57) that provides a leading edge (38). A first cooling passage (56) includes radially spaced legs (78, 80) extending laterally from one side of the leading edge toward another side of the leading edge and interconnecting to form a loop (76) with one another. A trench (62) extends radially in the exterior surface (57) along the leading edge (38). The trench (62) intersects one (80) of the first and second legs (78,80) to provide at least one first cooling hole (64a,64b) in the trench (62). A core for manufacturing an airfoil and a method of manufacturing this airfoil are also disclosed.
