COOLED TURBINE BLADE TIP SHROUD WITH FILM/PURGE HOLES

A cooled turbine blade shroud with purge holes located proximate regions of the tip shroud cooling cavity that experience cooling air flow recirculation or stagnation. The purge holes may be oriented radially from the cooling cavity to a surface, such as the outer top surface and/or inner/bottom sur...

Beschreibung
Zusammenfassung:	A cooled turbine blade shroud with purge holes located proximate regions of the tip shroud cooling cavity that experience cooling air flow recirculation or stagnation. The purge holes may be oriented radially from the cooling cavity to a surface, such as the outer top surface and/or inner/bottom surface, of the tip shroud, and may provide improved heat transfer and consequent cooling and enhanced tip shroud life.
