To provide a centripetal air-bleed system, capable of lowering the dynamic stress in an air-bleed tube by dissipating the energy of deformation and eliminating crossing of 1F mode and a drive source.
This air-bleed system includes an annular support 10 fixed to the surface of one of disks 3a and 3b, and a plurality of air-bleed tubes 11 mounted into the holes provided in the support 10 in approximately the radial direction. The air-bleed tube includes a means for reducing the vibration thereof at operation of a turbine engine. The means for reducing vibration of the air-bleed tube is fixed into the hole of annular support 10 and includes a damping tube 20, surrounding the inside portion of the air-bleed tube 11 in its radial direction. The radially outer end 26 of damping tube 20 fastens the corresponding zone 27 of air-bleed tube 11, and an annular space is provided in between the central zone of damping tube 20 and the air-bleed tube 11.
