<p>The impeller has an axisymmetric blade support (22) for supporting a set of blades. An intermediate part e.g. disk collar, extends in an axial direction from the support. A damping unit is placed on a face of the intermediate part. The damping unit has a layer made of viscoelastic material and a counterlayer made of rigid material. The damping unit is segmented in an axial and/or circumferential direction into two elementary damping units (301, 302). The layer and the counterlayer are attached to one another using an adhesive.</p> |
