Beschreibung
Zusammenfassung:	A centripetal-flow airbleed system for a gas-turbine engine including an annular support affixed to first and second disks of a compressor of the engine and having a plurality of peripherally spaced orifices defined along the radius thereof, a plurality of airbleed tubes each mounted in a substantially radial manner in one of the orifices of the annular support, and a vibration reduction device for reducing vibrations of the airbleed tubes. The device includes a plurality of damping tubes each mounted in one of the orifices of the annular support. The radially inner end of the damping tube encloses a portion of the airbleed tube and delimits an annular space defined therebetween.
