STATOR PART WITH SEGMENTED INNER RING FOR TURBOMACHINE Russian patent published in 2017 - IPC F01D11/18 

FIELD: turbo-machines.

SUBSTANCE: turbomachine stator part, substantially, consists of, at least, one axially passing outer ring (10), serving as internal ring mount, consisting of segments (20). Segments are installed next to each other so, that on rotor side relative to working blades (3) rotational movement they form continuous circular surface of circumference. Segments in circumferential direction are engaging with each other with possibility to form engagement. Individual segment (20) consists of uniformly structured material or, at least, from several bodies in radial direction, consisting of different materials, for example, from ceramic, wherein segment, created so, depending on turbomachine load range has compression or expansion previously specified characteristic.

EFFECT: due to proposed configuration and stator part segments arrangement enabling achievement of technical result consisting in reaching of compression and thermal expansions preset characteristics during operation.
