FIELD: mechanical engineering; compressors. SUBSTANCE: blade 18 of compressor stator consists of pressure and suction sides 20, 22 passing along chord between leading and trailing edges 24, 26 and in longitudinal direction, between root part 28 and top part 30. Blades constructs along chord towards middle part 36 between root and top. Said blade can bee curved at railing edge 26 together with narrow middle part. Invention increases efficiency of compressor and its surge capacity owing to enlarged capabilities of stator blades and improved their interaction with corresponding rotor blades of compressor. EFFECT: increased efficiency. 27 cl, 4 dwg
