FIELD: turbines or turbomachines.
SUBSTANCE: angular sector of stator with blades of gas-turbine engine with axial compressor includes sector of external ring intended for installation on casing of gas-turbine engine, sector of inner ring and crown of stator blades. Stator blade comprises two fastening legs extending in the circumferential direction, located in the thickness of one of the ring sectors so that to secure the stator blade tightly to the ring sector with rigidity of the angular sector. Two legs for fixation tightly pass in opposite direction and shifted in axial direction. Each stator blade comprises a blade extending between the sectors of the rings in the radial direction, wherein the two fastening legs extend perpendicular to the radial direction and perpendicular to the chord of the corresponding stator blade. In another version, the angular sector comprises a row of short posts for securing the stator blades tightly. Each short post extends into the channel in the radial length of the stator blade and comprises a hollow groove forming a recess in which the stator blade is tightly secured. One more invention of the group relates to gas turbine engine containing the above angular sectors and casing, on which angular sectors are fixed, as well as connecting blades arranged between angular sectors. Connecting vanes are fixed to casing and to angular sectors.
EFFECT: group of inventions improves rigidity of the stator angular sector.
