<p>A high-performance turbine stage capable of suppressing a reduction in performance of an axial-flow turbine due to an interference between stationary and moving blades, wherein the blade trailing edge lines of the stationary blades are formed in a shape protruded toward the front side thereof relative to radial lines extending radially from the rotating center of a rotating shaft, the blade gravity center lines of the moving blades are formed in a shape protruded toward the front side thereof relative to the radial lines extending radially from the rotating center of the rotating shaft, and, where the angles formed by the blade trailing edge tip parts and blade trailing edge base parts of the stationary blades and the radial lines are υnt and υnr and the angles formed by the blade tip part section gravity center lines and the blade base part section gravity center lines of the moving blades and the radial lines are υbt and υbr, 1<nr/<nt and 1<υbt<)υbr.</p> |
