  • Centrifugal blade for a turbine - rotor method for making the same
    Patent number: 4116149
    Abstract: A T-root, centrifugal turbine rotor blade which is manufactured from sheet stock. The T-root is produced by shaping the rim of the sheet stock under pressure. The sheet stock is given a rim contour which is geometrically similar to the final contour of the blade root, but is larger by a seam which is shaped under pressure for forming a T-shape having the rim contour of the blade root. After the sheet rim is shaped, a plurality of blades are cut or stamped from the sheet stock. The latter may be in annular form, and may possess various curvatures over its circumference. The sheet stock may be curved three-dimensionally before the T-rim produced.
