FIELD: engines and pumps.SUBSTANCE: invention relates to compressor stators, particularly, to those of gas turbine engines of air and ground applications. Compressor stator comprises the stator inner and outer frames (2) and (3), respectively, coupled along the airstream (4) by resilient conical front and rear flanges (5) and (6), respectively, and perforated shell ring (7) with air feed bores (10) arranged outside said inner frame (3). Said shell ring (7) has ledges (9) directed toward compressor stator axis (8). Radial flange (14) to couple inner frame (3) with rear resilient conical flange (6) has cutouts made on the side of said shell ring (7). Surface (17) of shell ring (7) ledges (9) facing the compressor axis (8) is located equidistant from the cutouts of radial flange (14). Air feed bores (10) are located on shell ring (7) ledges (9). Rear resilient conical flange (6) is provided with outer circular rib with radial grooves located opposite the shell ring (7) ledges (9).EFFECT: higher compressor efficiency.3 dwg |
