FIELD: engines and pumps.SUBSTANCE: proposed compressor comprises boundary layer active control device. This device comprises final stage distributor vanes with air boundary layer bleed orifice and first stage distributor vanes with bled air feed orifice. Said both orifices are slitted and made at vane suction face at boundary layer separation point. Every slitted orifice is communicated with the vane inner cavity. Receiver to collect air from vane inner cavities is arranged above final stage distributor vanes ends. Above vanes ends arranged are receivers for air distribution over vane inner cavities. Receivers are intercommunicated via pipeline for air collection and distribution.EFFECT: higher fault tolerance and reliability, expanded range of stable operation, decreased weight, simplified design.2 cl, 6 dwg |
