Rotorcraft rotor relates to shock absorbers of the trail hollows in the coupling sleeves of the blades has a hub of the rotor

摘要

The present invention relates to a rotorcraft rotor equipped with a device for damping lag oscillations of the blades (2) of the rotor. The blades (2) are mounted articulated on a hub (1) rotating the rotor by means of respective sleeves (3). The damping device comprises a set of dampers (6), each individually accommodated in a said sleeve (3) and deformable between two fastening points (8,9) to the sleeve and on a member (7) to the hub (1) by means of a rod assembly (10). For each of the sleeves (3), the shock absorber (6) that accommodates a sleeve (3) is engaged which is articulated on the connecting rod assembly (10) by means of a lever arm (11) is articulated on the sleeve (3).
