FIELD: turbines or turbomachines.
SUBSTANCE: stator of axial turbomachine comprises annular row of stator blades, inner bandage and blade body. Annular row of stator blades includes support blades inseparable from internal platforms, and connecting blades. Inner bandage is formed by inner platforms of support blades and inner segments of bandage, which are attached to connecting blades. Inner platforms of support blades and internal segments have the same axial length. Blade body comprises several support blades and one of inner platforms, which is common for each of blade body support blades, and external platform, which is common for each of blade body support blades. Said one of inner platforms comprises four contact surfaces perpendicular to turbomachine rotational axis and touching axially with two inner segments. Each of two internal segments is in contact with two of four contact surfaces of said one of internal platforms. Said one of inner platforms comprises inner U-shaped slot which is open inward in radial direction. Each of two segments comprises a part of smaller radius and axial thickness, which is inserted into internal U-shaped slot. Another invention relates to a turbomachine comprising said stator, which is a stator of a low pressure compressor.
EFFECT: group of inventions allows improving reliability of stator of axial turbomachine due to limitation of axial vibrations of band segment.
