Abstract
1302661 Turbine rotors FIAT SpA 15 July 1971 [27 July 1970] 33227/71 Heading FIT A gas turbine rotor comprises a one-piece central disc 4 to the periphery of which are welded, e.g. by an electron beam, the surfaces 13 of blade root portions 7, the latter including side plates 7, 8 which collectively define two substantially continuous annular faces 14, 15 forming extensions of the side faces of disc 4. A radially outwardly tapering core 10 and a bridge piece 11 are connected between plates 7, 8 of each root portion 7, the latter being cast integrally with blade 3. Radial chambers (16) Fig. 1 (not shown) are defined between adjacent root portions 7 and supplied with cooling air through passages 17, 18 in disc 4, the air flowing from the chambers into the interiors 3a of blades 3. Several blades may be cast integrally with each root portion.
