摘要：FIELD: machine building.SUBSTANCE: stator of compressor of axial turbine machine contains ring group of blades passing in radial direction, internal casing, through which the internal ends of blades pass, and at least one strap. Internal casing contains ring segments located end towards end. The strap passes along length of the circle along internal surface of the casing, and is connected with engagement means on the internal ends of the blades for their fixation. The strap passes continuously along at least two adjacent ring segments, and is located at distance from the internal surface of the casing. The internal surface of the casing is coated with layer of abraded material comprising the said strap. The other invention of the group relates to the LP compressor of the axial turbine machine comprising the said stator with blades.EFFECT: group of inventions ensures rigidity of the structures of the compressor stator of the axial turbine machine, and converts it to LF vibrations.20 cl, 4 dwg
