Abstract

Control-stage integral blade set for steam turbine, with a rotor, the rotor including radially extended flanges, with smooth, opposite faces which define at least one pair of annular grooves. The set comprises a plurality of blades secured to a unitary platform. The set also comprises a plurality of root parts hanging from the platform in the opposite direction from the blades. The root parts extend along the platform in a circumferential direction. Each root part fits inside an annular groove of the rotor. Finally, the set comprises at least three openings formed in said rotor part and arranged in line with relevant openings in the rotor. Each opening is formed by location in a common rotor circumference and extension parallel to a shaft (axis) of the rotor in order to receive a bolt in the aligned openings in order to secure the set to the rotor.
