Shrouded rotor blade for a turbomachine

摘要

A rotor blade (14) having a wing (52,54) and beam (42) construction for a tip shroud (30) is disclosed. Various construction details are developed for providing the shroud with a depression (48) in the shroud (30) and a transition zone (34) that extends from the suction side (26) and pressure side (24) of the airfoil to provide a flow path surface of the shroud. In one detailed embodiment, the tip shroud has a depression (48) generally outwardly of the airfoil and generally following the curve of the pressure and suction sides (24,26) of the airfoil from the leading edge region (36) to the trailing edge region (38).
