Abstract

728,710. Turbines and compressors. ESCHER WYSS AKT.-GES. Jan. 28, 1953 [Feb. 13, 1952], No. 2462/53. Class 110 (3). In an axial-flow turbine or compressor, blades are mounted in slots in a blade carrier, the slots extending substantially parallel to the chords of the blades and having parallel lateral faces. The blades have a constant cross-sectional profile throughout their length and one or more root pieces are fitted to each blade where the blades are mounted in the blade carrier so as to form a prismatic-shaped root having parallel lateral faces which lie against the faces of the associated slot. The blades and root pieces are secured by pins, at least one for each blade, which extend through the blade carrier, blade and root piece. The root piece may be welded to the blade. In Fig. 2, the blade 3 is mounted in a slot 2 in the rotor disc 1 and the root portion is formed by two root pieces 4, 5 at either side of the root end of the blade, the blade being secured in position by two pins 6. In a second embodiment in which one face of the blade is plane, only one root piece is provided. In an embodiment in which the blade is hollow and is formed of sheet metal, two root pieces are used and they bear against each other beyond the leading and trailing edges of the blade. Alternatively, an additional piece 17, Fig. 5, may be inserted into the hollow blade in the region of the root pieces.
