Abstract

An axial flow gas turbine having inner and outer casings, the inner casing being supported within the outer casing by horizontal keying members therebetween. Arrays of stationary integral vane segments and adjacent arcuate blade ring segments are supported inwardly from and interlocked with the inner casing by arcuate segmented support members. The arcuate segmented support members are each fixedly attached at their centermost point to the inner casing. This arrangement permits thermal expansion between mating members with respect to each other. The employment of individually locked stationary integral vane segments and arcuate blade ring segments provide an arrangement where blade path leakage harmonics are limited to the number of such segments in each of their respective planes across the turbine, thus eliminating the deleterious effects created by even harmonics of two stationary half blade segment structures.
