ABSTRACT:
An axial compressor for a turbomachine is fitted with a device for centripetally bleeding turbine-cooling air. The compressor includes at least two rings of blades, an outer shroud having holes, and a fixed ring of stator vanes placed in the stream between the moving rings of blades. The holes are inlets for the bleed device, opening out into an annular groove beneath the interstice separating the inner platforms of the stator vanes from the rim of the upstream disk. The groove is fitted with fixed air guide devices to impart a centripetal swirling motion to the air flowing therein in the same direction as the compressor so as to reduce the velocity of the air relative to the rotating holes.
