Abstract

1,224,759. Bladed rotors. ROLLS-ROYCE Ltd. Sept. 8, 1969 [Sept.20, 1968], No.44949/68. Heading F1T. A bladed rotor, e.g. for a turbine or compressor of a gas turbine engine, comprises a disc 20 the periphery of which is alternately provided with smoothly curved recessed portions 21 and unrecessed portions 22, each of the latter having secured thereto the root 26 of a blade 23. The opposite surfaces 33, 34 of each root 26 merge smoothly with the surfaces of the adjacent recessed portions 21 to direct stress concentrations away from the root and into the recesses. Each root 26 has cooling fins 32 and extends radially inwardly from a platform 25 through a distance which is at least a quarter of the total radial length of the blade. The root 26 may be secured directly to the portion 22, e.g. by diffusion bonding or electron beam or resistance welding, but where the materials of the root 26 and disc 20 are incompatible intermediate members 30, 31 may be provided.
