FIELD: turbo-machines.
SUBSTANCE: group of inventions relates to axial turbine machine low pressure compressor stator. Stator comprises circular row of stator blades 26, having radial ends, passing through inner casing 28 holes 36, and containing radial fixing slots 38. Slots 38 have conicity formed by hooks 44. Stator comprises ring 30 for fixation of blades 26 on casing 28. Ring 30 is bent along circumference for its installation in fixing slots 38 and has shape of strip with arc-shaped lateral cross-section, which is in contact with cones and rests against them so, that ring 30 was retained inside slots 38. Casing 28 comprises abraded material 32 circular layer, which surrounds ring so, that to block ring 30 arched shape curvature in order to prevent disengagement of its contact with slots 38 cones.
EFFECT: group of inventions is aimed at improvement of fixation between blade and ring with arc-shaped lateral cross-section in axial turbomachine, as well as at increasing of stator with blades service life.
