<p>An industrial turbine assembly (10) comprises a plurality of rotating blade portions (12) in a spaced relation with a stationary shroud (14), the rotating blade includes a root section (16), an airfoil (18) having a pressure sidewall (22) and a suction sidewall (24) defining an outer periphery and a tip portion (20) having a tip cap (30). An offset squealer (50) is disposed on the tip cap (30), the offset squealer (50) is positioned inward from the outer periphery of the rotating blade (12). The offset squealer (50) increases the flow resistance and reduces the flow of hot gas flow leakage for a given pressure differential across the blade tip portion (20) so as to improve overall turbine efficiency. <IMAGE> <IMAGE></p> |
