Abstract

PURPOSE: To increase the diameter of an air introducing hole and a cooling hole to enhance cooling performance, by providing the air introducing hole in a side of the shank portion of moving blade of a turbine and drilling from the tip of a profile portion a cooling hole which communicates with the air introducing hole.
CONSTITUTION: In a gas turbine's moving blade comprising a profile portion 11, a shank portion 12 and a dovetail portion 13, a side plate 14 is located on the side surface of the shank portion 12 to define a cooling air introducing passage. An air introducing hole 16 is provided in a side of the shank portion 12. A cooling hole 17, which communicates with the air introducing hole 16, is drilled from the tip of the profile portion 11.
