PROBLEM TO BE SOLVED: To provide a rotary machine blade having an asymmetric part-span shroud.SOLUTION: A suction-side section of a part-span shroud is coupled to a suction-side surface of an airfoil of the blade. A first point of the airfoil suction-side surface, defined where a trailing edge of the suction-side section intersects the airfoil suction-side surface, is located upstream from a second point, defined where a throat intersects the airfoil suction-side surface. A third point, defined where a leading edge of the suction-side section intersects the airfoil suction-side surface, is located downstream from a fourth point, defined at a leading edge of the blade. A pressure-side section of the part-span shroud is coupled to a pressure-side surface of the airfoil. A fifth point of the airfoil pressure-side surface, defined where a trailing edge of the pressure-side section intersects the airfoil pressure-side surface, is located downstream from the first point. |
