Abstract: A method of manufacturing a blade for use with a rotary machine includes coupling a suction-side section of a part-span shroud 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 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 downstream from a fourth point, defined at a leading edge of the blade. The method also includes coupling a pressure-side section of the part-span shroud 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 downstream from the first point.

Abstract: A device receives sensed operation parameters related to the operation of a machine. The device utilizes the sensed operation parameters in a first analyzer that generates first characteristics related to degradation of the machine and utilizes the sensed operation parameters in a second analyzer configured to generate second characteristics related to thermal characteristics of the machine, wherein the thermal characteristics include thermal stresses present in the machine. The device also utilizes the first and second characteristics and a third characteristic related to operator behaviors related to the current operation of the machine to generate remaining useful life characteristics of components of the machine and generates operational set points for control of the machine based in part on the remaining useful life characteristics, desired machine performance characteristics based on the operator behaviors, and maintenance characteristics of the machine.
