Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly provided with stator vane trains to be repeatedly positioned after replacement and having an allowable level of durability and a replacing property. SOLUTION: A stator vane blank for forming a stator vane for a rotary machine includes a forged head part 84 having a pair of surfaces provided with an angle forming an outward surface 104, and these surfaces has an angle larger than the angle of a pair of surfaces facing to an air foil and provided with an angle forming an inward surface 106. The outward surface 104 is provided with about nine degree of angle α, and the inward surface 106 is provided with about three degree or less of angle β.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes repeatedly positionable after replacement, having an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises a plurality of vanes extending into an operating medium gas flow passage through a case extending in circumferential direction. In this case, the stator assembly comprises a surface 76 facing inward on a base part 48, and the inward facing surface 76 is connected, in the state of being installed, to a flat surface 74 corresponding to a non-flow passage surface of a casing at a position of each vane. In one embodiment, these surfaces are on the same plane.

Abstract: PROBLEM TO BE SOLVED: To provide a stator assembly having a row of stator vanes with an allowable level of durability and replaceability. SOLUTION: This stator assembly comprises shrouds. The detail of various coinfigurations limiting the movement of stator vanes 28 into a flow path by the limitation of the shrouds is expanded. For example, a clip member 62 extends throiugh an opening part 64 located at a vane tip part 52 of the stator vane 28, and the clip member 62 is disposed on a non-flow path surface of an inside shround 56 so as to limit the vane tip part 52 of the stator vane 28 for an inward movement.
