<P>PROBLEM TO BE SOLVED: To provide a highly efficient and inexpensive turbine stationary blade, that reduces the number of blades in an axial-flow turbine, while reducing secondary-flow loss. <P>SOLUTION: In the turbine stationary blade, when a differential pressure between a face side and a back side of the blade at the same axial chord position is defined as a blade load and a ratio between the axial distance xp of a maximum load position 32, where the blade load becomes maximum, from a leading edge 8 of the blade and the axial chord length Cx is defined as a maximum load relative position, the axial chord lengths Cx of a blade root portion and a blade tip portion are longer than the axial chord length Cx of a blade intermediate height, and the maximum load relative positions of the blade root portion and the blade tip portion are set closer to the blade trailing edge side than the maximum load relative position of a blade intermediate portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
