Abstract

Axial compressor (1) comprising: a tubular casing (2); a drive shaft (3) extending in axially rotatable manner inside the central cavity (2a) of said casing (2) coaxial to the latter; a number of annular blade rows (4) spaced along and stably fixed to the drive shaft (3); a number of annular vane rows (6) stably fixed to the peripheral wall (8) of said casing (2) intercalated to the annular blade rows (4); at least one bleed cavity (9) formed within the peripheral wall (8) of said casing (2); at least one bleeding slot (11) which is formed in the peripheral wall (8) to put said bleed cavity (9) into direct communication with the central cavity (2a) of said casing (2); and at least one air deflector member (15) which is located inside the bleed cavity (9), and is adapted to divert/guide the airflow (f) of compressed air entering and/or circulating inside the bleed cavity (9) for reducing the air turbulence area inside the bleed cavity (9) .
