Abstract

1287223 Turbine rotor blading ASSOCIATED ELECTRICAL INDUSTRIES Ltd 19 Jan 1971 [2 Feb 1970] 4866/70 Heading FIT The blades 2 of a turbine rotor are mounted in groups 1 of two or more blades, each group having a common root 3 and a common shroud portion 4, movement restraining means interconnecting the shroud portions of adjacent groups. In the arrangement shown the restraining means is a metal strip 5 riveted to shroud portions 4. In a modification, Fig. 2 (not shown) the restraining means is a strip (6) fitting in a dovetail slot (7) in the radially outward surfaces of shroud portions 4 with freedom for circumferential movement. In a further arrangement, Fig. 3 (not shown) lacing wires (8) passing through grooves (9) in opposite sides of the shroud portions are used. In all the arrangements each common root 3 or shroud portion 4 may be formed from a single piece of material or from separate pieces rigidly secured together, e.g. by welding.
