<p>The rotor has a damper device provided for damping lead-lag oscillations of blades (2) that are individually hinge-mounted on a rotary hub (1) through sleeves (3). The device comprises a set of dampers (6), where each damper is individually housed in each sleeve. Each damper is elastically deformable between two fastening points (8, 9) through which the damper is placed under stress between sleeve housing of the damper and an engagement element (7) for engaging the hub through a linkage (10). The damper is in hinged engagement with the linkage through a lever arm (11) hinged to sleeves.</p> |
