Abstract

709,748. Turbine and compressor rotors. ROLLSROYCE, Ltd. Aug. 25, 1952 [Aug. 24, 1951], No. 20046/51. Class 110(3) In a rotor drum for an axial-flow turbine or compressor comprising a plurality of axially-spaced discs 10, the discs have axially-directed flanges 13 which abut to determine the axial spacing of the rims, and an annular sheet metal member 14 is provided between each pair of disc rims to constitute the surface of the rotor drum therebetween. The annular member has inwardly-projecting beaded flanges 14e or 14h, the beads of which engage radially inwardly-facing shoulders 10d or 10f at the edges of the disc rims so as to retain the member in position, the beads also being radially disposed to prevent axial disengagement of the blade fixing means. The first-disc rim in Fig. I is formed with two flanges 10c and blades 11 are pivotally mounted therebetween by engagement with the pins 12. The second and third disc rims have axially-directed slots in which the fir-tree type blade roots are mounted.
