摘要： PROBLEM TO BE SOLVED: To provide a turbo machine stator blade reducing defect accompanying large variation of temperature gradient.
SOLUTION: The turbo machine stator blade includes a porous open liner 18 defining an annular cavity 20 between an outer wall of the liner and an inner wall of the blade 10, an intake opening 24 sending cooling air to an inner side of the liner, an exhaust opening 28 discharging part of cooling air form the blade. One end 18A of the liner is fixed on the blade and another end 18B is not fixed and freely sides along an inner edge part 16A of the blade by relative heat expansion effect between the liner and the inner wall of the blade. The open liner is provided with a plurality of pores distributed on only two predetermined zones of the liner, a first series of pores 30 are arranged with facing an inner wall of a front edge 12Ai, a second series of pores 32 are arranged with facing an inner wall of a rear edge 12Bi, pores penetrating through the liner of the second series of pores are arranged not to hit a bridge 23 of the blade.
