Film cooled turbine airfoil having trench segments on the exterior surface

An airfoil (10) includes a platform (12) and an exterior surface (18) connected to the platform (12). The airfoil may be used, for example, as a rotating blade or stationary vane in a turbine. A plurality of trench segments (40) are on the exterior surface (18) of the airfoil, and a single cooling p...

Beschreibung
Zusammenfassung:	An airfoil (10) includes a platform (12) and an exterior surface (18) connected to the platform (12). The airfoil may be used, for example, as a rotating blade or stationary vane in a turbine. A plurality of trench segments (40) are on the exterior surface (18) of the airfoil, and a single cooling passage (50) in each trench segment (40) supplies a cooling media to the exterior surface (18).
