Beschreibung
Zusammenfassung:	A turbine blade having a tip (10) including a tip shelf (15) through which pass one or more diffuser cooling holes (17), the diffuser cooling holes (17) directing the flow of cooling gas along the tip shelf (15), spreading the flow of cooling gas more evenly along the tip shelf (15) and enhancing the formation of a curtain of cooling air along the tip shelf (15), leading to lower blade tip (10) temperatures, reduced diversion of cooling air, and greater turbine blade life.
