Abstract: The turbine blade (10) comprises an airfoil section (16) and a hollow blade tip shroud (18) joined to the airfoil section (16). The hollow tip shroud (18) is preferably a cast, compartmentalized structure and has a plurality of ribs (40) acting as load bearing structures and defining a plurality of shroud core sections (42,44,46,48,50,52). Each of the shroud core sections (42,44,46,48,50,52) communicates with a supply of cooling fluid and has a plurality of apertures (66) for supplying cooling fluid to exterior portions of the shroud.
