Abstract

PURPOSE: To prevent a cooling medium flowing path from rising the pressure in such a way of making film cooling on the blade by providing a steam separating part on the half way to the flowing path, and by making steam jetting holes on the cores, in a gas turbine blade in which a sinuate cooling path is installed.
CONSTITUTION: A sinuate flowing path 4 is installed in a turbine dynamic blade 1, and a steam flowing path 6 is provided on its half way through a steam separating part 5. Steam jetting holes 7 are made on cores 2 corresponding to the flowig path 6. Cooling water is made to flow in through the root of the blade, evaporated by the heat from the cores 2 and the film 3, and part of the steam is jetted through the steam flowing path 6 via the steam jetting holes 7 to a high temperature main gas flowing path.
