Abstract

1489095 Turbine bladed rotor KHARKOV POLITEKHNI INST IM VI LENINA 27 Dec 1974 [28 Dec 1973 30 Sept 1974 20 Nov 1974 (3)] 55970/74 Heading FIT A turbine bladed rotor assembly comprises a rotor disc having blades mounted thereon, the blades being of two-tier construction, each blade comprising an outer blade 4, a blade root 5, and a dividing platform 3, there being two blade parts 6 and 7 between the blade root and platform, the blade parts 6 and 7 of each blade forming with the adjacent blades, blades which constitute the blades 2 of the inner row. In Fig. 5 each two-tier blade comprises an outer tier blade 4 and three parts 12, 13, 14 of inner tier blades, each inner tier blade upon assembly being formed of parts 12, 13, 14. In Fig. 7 each two tier blade comprises an outer tier blade and three parts 17, 18, 19 of inner tier blades, each inner tier blade upon assembly being formed of parts 17, 18, 19, the trailing edge part 19 not being connected to the dividing platform. In Fig. 9 each blade comprises two inner tier blades 22, 24, the blades upon assembly constituting effective blades such as 22, 23 and 25, 24 which define convergent-divergent flow passages a 0 , a<SP>1</SP> 1 through which steam flows as indicated by the arrow.
