Abstract
692,213. Turbines and compressors. COMPAGNIE ELECTROMECANIQUE. Sept. 28, 1950 [Oct. 3, 1949], No. 23758/50. Class 110(iii) In an axial flow turbine or compressor, the rotor is formed of a number of discs, the rims of which are of Y-section whose arms are very thin compared with their length, and the rotor blades are secured to the arms of the Y-section rim by means of bolts. The arms of the Y-section rim are formed with shoulders which co-operate with a sealing means. In one embodiment, Fig. 1, the rotor blades 4 are mounted between adjacent rotor discs 1, the blade roots being located in circumferential grooves 5 in the two adjoining arms of the Y-section rims 2, 3 and being secured by bolts 6 which also secure the U-shaped distance pieces 7 which are mounted between the arms of each Y- section rim. The fixed blades 11 have a shroud 12 with inwardly projecting edges 13 which co-operate with the shoulders formed on the rim. In a second embodiment, Fig. 2, the rotor blades 4 are mounted between the arms of each Y-section rim and the distance pieces 17 are mounted between the adjacent arms of adjacent discs, bolts 6 and sealing means 12, 13, being provided as in the first embodiment. Tubular spaces 10 are provided between the discs.
