<p>A turbine blade (10) includes an airfoil tip (30) with first and second tip ribs (36,38) extending from a tip floor (40). The ribs (36,38) extend along the opposite pressure and suction sides (20,22) of the blade (10) and are joined together at opposite leading and trailing edges (24,26). A tip baffle (42) is nested transversely between the ribs (36,38), and conforms with the second rib (38) to bifurcate the airfoil tip (30) into first and second tip pockets (44,46) extending along the corresponding pressure and suction sides (20,22).</p> |
