FIELD: machine engineering.
SUBSTANCE: sector of the stator blades for attachment to the axial turbomachine body, comprises several blades with the platforms connected so as to describe the circle arc, and with an aerodynamic profile projecting from the inner surface of each platform and directed toward the circular arc center described by the platforms. One of these platforms contains a fixing screw on its outer surface, and the other platform does not contain a fixing screw. The platforms are fixed together at their adjacent edges. The aerodynamic profiles contain mechanical means of fastening the inner body at their inner ends. Another group invention relates to the axial turbomachine stator comprising a body defining a cylindrical wall, and blades arranged on the inner wall surface, wherein the blades form sectors formed as described above. Another group invention relates to the axial turbomachine comprising a rotor containing rotor blades and the above stator.
EFFECT: reducing the sector weight of the stator blades, and its secure fixing to the body.
