Damping device

An assembly for a turbomachine including a first rotor module (2) with a first blade (20), and a second rotor module (3), connected to the first rotor module (2). The second rotor module includes a second blade with a smaller length than the first blade (20). A damping device (4) is attached to the...

Beschreibung
Zusammenfassung:	An assembly for a turbomachine including a first rotor module (2) with a first blade (20), and a second rotor module (3), connected to the first rotor module (2). The second rotor module includes a second blade with a smaller length than the first blade (20). A damping device (4) is attached to the second rotor module (3) and includes a radial external surface (40) supported with friction against the first module (2), so as to couple the modules (2, 3) for the purpose of damping their respective vibrational movements during operation.
