Abstract
A rotor blade having a wing and beam construction for a tip shroud is disclosed. Various construction details are developed for providing the shroud with a depression in the shroud and a transition zone that extends from the suction side and pressure side of the airfoil to provide a flow path surface of the shroud. In one detailed embodiment, the tip shroud has a depression generally outwardly of the airfoil and generally following the curve of the pressure and suction sides of the airfoil from the leading edge region to the trailing edge region.
