Abstract
A turbine blade includes an airfoil having first and second tip ribs extending along the opposite pressure and suction sides thereof. The tip ribs are spaced apart between the leading and trailing edges of the airfoil to include a tip baffle. The baffle extends chordally in counter profile with the first rib to define a first pocket, and in counter profile with the second rib to define a second pocket.

A turbine blade comprising:
- an airfoil, platform, and integral dovetail;
- said airfoil having opposite pressure and suction sides extending in chord between leading and trailing edges and extending in span from root to tip;
- said tip including first and second ribs extending from a tip floor along said pressure and suction sides, respectively;
- and
- said first and second ribs are joined together at said opposite leading and trailing edges and are spaced transversely apart to include a tip baffle extending chordally in counter profile with said first rib to define a first pocket therealong and in counter profile with said second rib to define a second pocket therealong.
A turbine blade comprising an airfoil tip having a pressure-side first rib joined to a suction-side second rib at opposite leading and trailing edges and spaced transversely apart to include a tip baffle extending chordally in counter profile with said first rib to define a first pocket therealong and in counter profile with said second rib to define a second pocket therealong.
