Abstract (en)
In an embodiment, a system includes a rotary machine. The rotary machine includes a rotor (54) having a plurality of blades (52) and a segmented stator having a plurality of stator segments (74,76) arranged circumferentially about the plurality of blades (52). Each adjacent pair of first and second segments (74,76) of the plurality of stator segments includes a recess (60) extending circumferentially across an intermediate joint (70) between the first and second segments (74,76). Furthermore, each recess (60) includes at least one eccentricity control insert (62) configured to mitigate eccentricity of an inner circumference of the segmented stator due to thermal expansion or thermal contraction of the segmented stator.
