Abstract

1,063,918. Turbine rotors. GENERAL MOTORS CORPORATION. Feb. 24, 1966 [March 10, 1965], No. 8114/66. Heading FIT. The rotor wheels 28, 28' of adjacent axial flow turbine stages in a gas turbine engine are spaced apart by an annular spacer 96 formed from arcuate segments (98), Fig. 4 (not shown), slidably connected to each other by interfitting tongues (104) and grooves (102). The upstream and downstream ends of the spacer 96 have annular grooves 106, 108 respectively which engage with annular flanges 82, 92' on annular blade locking plates 62, 50'. Locking plate 62 has spaced slots (66) therein, Fig. 4 (not shown), the edges 72 of which engage, after a small angular movement of the plate, with tangs 38 on the blade roots 32, thus preventing forward movement of the roots out of their fir-tree slots 30. A similar locking plate 50 having slots 54 with edges 55 engages tangs 36 on blade roots 32 to prevent rearward movement of the roots out of slots 30. The locking plates on wheel 28' are similar to plates 50, 62 on wheel 28. Plate 62 has spaced apertures (76) aligned with cavities 74 in the wheel 28, the apertures and cavities receiving a lug 114 on each spacer segment (98) to locate the segments circumferentially. Vibration dampers (48), Fig. 3 (not shown), are mounted below the hollow platforms 42 of adjacent blades 34.
