FIELD: turbines or turbomachines.
SUBSTANCE: blade unit of compressor of axial turbomachine includes wall limiting circular flow of turbomachine in radial direction and containing fastening seat, blade and fastening layer. Blade is fixed in the fastening seat and passes radially, and the fastening layer surrounds the blade and is located between the blade and the seat. Seat and blade have irregularities in contact with fastening layer so that to provide fixation due to adherence of material for attachment of blade in wall. Said seat irregularities are formed by multiple irregularities arranged one above the other in radial direction while unevenness of the blade is formed by multiple irregularities arranged one above the other in radial direction. Another invention of the group relates to compressor of axial turbomachine containing the above blade assembly. One more invention of the group relates to an axial turbomachine comprising the above blade unit and the above compressor.
EFFECT: group of inventions improves reliability of turbomachine blade attachment.
