Title (EN) ROTOR FOR THE COMPRESSOR OF A TURBINE ENGINE COMPRISING A CENTRIPETAL AIR-COLLECTING MEANS
(FR) ROTOR DE COMPRESSEUR D'UNE TURBOMACH INE COMPORTANT DES MOYENS DE PRELEVEMENT D'AIR CENTRIPETE
Abstract: front page image
(EN)The invention relates to a rotor for the compressor of a turbine engine that includes at least two coaxial discs (118, 120) carrying blades and connected together by a substantially cylindrical revolution wall (136), a centripetal air-collecting means including air passages (148) extending through the wall, and radial vanes (160) for rectifying the air flow exiting the passages in the wall, said vanes being carried by one of the discs and being substantially aligned in the radial direction with the passages of the wall.
(FR)Rotor de compresseur d'une turbomachine, comprenant au moins deux disques coaxiaux (118, 120) portant des aubes et reliés entre eux par une paroi de révolution (136) sensiblement cylindrique, des moyens de prélèvement d'air centripète comportant des passages d'air (148) traversant la paroi, et des ailettes radiales (160) de redressement du flux d'air sortant des passages de la paroi, ces ailettes étant portées par un des disques et sensiblement alignées en direction radiale avec les passages de la paroi.
