TURBINE BLADE

摘要

Provided is a turbine blade, in which plate-shaped ribs for partitioning a blade front and a blade back are disposed at the substantial blade center portion along the center line jointing the front edge and the back edge, and in which at least two cavities are formed to have no communication between the front side and the back side. The turbine blade is characterized in that the cooling air flow to the back side is made lower than that to the front side by a pressure loss member for the cooling air to enter the cavity on the back side.
