TURBINE BLADE AND GAS TURBINE EQUIPPED WITH THE TURBINE BLADE

摘要

PROBLEM TO BE SOLVED: To provide a turbine blade and a gas turbine equipped with the turbine blade capable of completely making a watershed of a film layer with the cooling air to zero or minimizing the watershed compared with the previous one. SOLUTION: In the turbine blade having a film cooling structure blowing the cooling air induced into the turbine inside from an air plenum formed at the surface of the turbine blade, the air plenum is characterized in forming along a setting direction of the turbine blade 110 by at least slit 120 for film cooling.
