PURPOSE:To enhance strength of a gas turbine blade comprising a sheath and insertions by connecting the sheath and the insertions by means of a reinforcement. CONSTITUTION:In a void enclosed by a sheath 1, insertions 2, 4 are introduced from outside, with the result that a cooling duct is thereby formed. At least one point along the length side of the sheath, a reinforcement 3 is fixed and linked with insertions 2, 4. Accordingly, deformation of the sheath 1 can be curbed to the minimum even when difference in the pressure between inside and outside the housing is large, and strength of the blade can be augmented. |
