Abstract
A turbine blade includes an airfoil having first and second tip ribs extending along the opposite pressure and suction sides thereof. A tip baffle bifurcates the airfoil tip into two pockets, with a first pocket being laterally open at its aft end to recover leakage flow, and a second pocket being laterally closed.
Claims24
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 leading edge and spaced transversely apart at said trailing edge to define an aft outlet, and a tip baffle extends chordally between said ribs to define a first pocket along said first rib laterally open at said aft outlet, and also defining a laterally closed second pocket along said second rib.
