    摘要： The invention is intended to reduce the profile loss. For that purpose, according to the invention, a plurality of turbine blades are arranged in the circumferential direction of a turbine driven by a working fluid. Each of the turbine blade is formed such that the curvature of a blade suction surface, which is defined by the reciprocal of the radius of curvature of a blade surface on the blade suction surface side, is decreased monotonously from a blade leading edge defined as the upstream-most point of the blade in the axial direction toward a blade trailing edge defined as the downstream-most point of the blade in the axial direction.

    摘要： Suppressing profile loss of a moving blade due to radial flow without an increase in the length of a shaft of a turbine is disclosed. The degree of reaction on an inner circumferential side is set to an appropriate degree, reducing profile loss due to supersonic inflow, and improving turbine efficiency. A steam turbine stator vane has a trailing edge with a curved line when the stator vane is viewed from a downstream side in the axial direction. The curved line has an inflection point located on an outer circumferential side with respect to the center of the stator vane in the height direction of the stator vane. An inner circumferential portion of the curved line is located on the inner circumferential side with respect to the inflection point. An outer circumferential portion of the curved line is located on the outer circumferential side with respect to the inflection point.

    摘要： An axial turbine includes a plurality of stages, each of the plurality of stages having stationary blades adjacent to each other along the turbine circumferential direction and corresponding moving blades adjacent to each other along the circumferential direction, each of the moving blade being located downstream of a corresponding one of the stationary blades along a flow direction of a working fluid, so as to be opposed to the corresponding stationary blade. In this axial turbine, each of the stationary blades is formed so that the intersection line between the outer periphery of the stationary blade constituting a stage having moving blades longer than moving blades in a preceding stage and a plane containing the central axis of the turbine, has a flow path constant diameter portion that includes at least an outlet outer periphery of the stationary blade and that is parallel to the central axis of the turbine.

    摘要： The axial-flow turbine includes an extraction chamber 15 disposed on the outer circumference of a turbine blade chamber 12 and an extraction opening 16. An outer diaphragm 8 forming the downstream-side wall surface of the extraction chamber 15 is provided with a projection 21 formed more radially inwardly than the downstream-side edge on the outer circumference of an adjacent bucket 2 on the upstream side of the extraction opening 16 to form the downstream-side wall surface of the extraction opening 16. The projection 21 forms an upstream-side wall surface 18 of the outer diaphragm 8 for leading a part of the working fluid to the extraction chamber 15, and an inner wall surface 19 of the outer diaphragm 8 for leading the remaining working fluid to a bucket 11 on the downstream side of the extraction opening 16.
