ABSTRACT:
A coolable airfoil for use in gas turbine engine component such as a turbine blade or vane is provided with a one-piece integrally formed double shell outer wall surrounding at least one radially extending cavity. The inner and the outer shells are integrally formed of the same material together with tying elements in the form of continuous ribs which space apart the shells, mechanically and thermally tie the shells together, and form convective cooling passages therebetween.
