A turbine blade includes an airfoil having an internal cooling circuit with a first flow passage disposed directly behind the leading edge followed by a second flow passage separated therefrom by a corresponding bridge. The bridge includes a row of impingement apertures for cooling the leading edge. The suction sidewall of the airfoil includes a row of diffusion film cooling first holes extending in flow communication with the first passage. The first holes have a compound inclination angle, with a quadrilateral cross section forming a generally teardrop shaped outlet in the convex contour of the suction sidewall.

A metering plate includes a body having a first end and a second end, at least one opening extending through the body, and at least one projection extending outwardly from the body. The body is configured to be resistance welded to at least one of a turbine engine blade and a turbine engine stator vane using the projection such that the body at least partially controls fluid flow into at least one of the turbine engine blade and the turbine engine stator vane.
