<P>PROBLEM TO BE SOLVED: To sufficiently suppress a rise of a temperature of a member of a turbine stationary blade 1 as a whole after sufficiently securing the mechanical durability of the turbine stationary blade 1, and to improve the cooling performance of the turbine stationary blade 1. <P>SOLUTION: A cut-back part 29 is formed at the rear end of the body side of a blade body 3 while communicating with a cooling passage 9, a plurality of partitions 31 for partitioning the downstream side of the cooling passage 9 into a plurality of slots 33 are formed at the upstream side of the cut-back part 29 in the blade body 3 at intervals in a span direction SD, a plurality of protruding walls 35 which are protruded in the downstream edge of the cut-back part, and continuous to the corresponding partitions 31 are formed at the upstream edge of the cut-back part 29 at intervals in the span direction, and a protruding dimension L1 of each protruding wall 35 is shorter than a width dimension L2 of the cut-back part 29. <P>COPYRIGHT: (C)2012,JPO&INPIT |
