Beschreibung
Zusammenfassung:	A turbomachine assembly 1 comprising a first rotor module 2 comprising a disk 21, a first blade 20 being mounted on the external periphery of the disk 21, the first blade 20 comprising a platform 25 and a support 27, a second rotor module 3, connected to the first rotor module 2 by means of at least two attachments 22 and comprising a second blade of smaller length than the first blade 20, and a damping device 4 attached to the attachment 22 between the first 2 and the second 3 rotor module so as to dampen their vibrational movements during operation, and comprising: a head 40 comprising a first radial external surface 42 supported with friction against the platform 25, and two attachment feet 41 extending on either side of the support 27 of the first blade 20.
