FIELD: machine building.
SUBSTANCE: turbine unit stator sector comprises sectors of inner and outer rings and multiple vanes jointing them together. Radial cutouts are arranged between two adjacent vanes of inner or outer ring sector to divide said sector into elementary segments to match the number of vanes. Said cutouts have damping plate seats. Said plates comprises, at least, one layer of visco-elastic substance. Every said layer is arranged between two metal layers. Other invention of proposed set relate to compressor and turbine comprising, at least, one above described sector. One more invention of the set relates to turbine unit comprising said compressor and/or turbine.
EFFECT: reduced vibration of turbine stator sector.
