FIELD: transport.
SUBSTANCE: invention relates to production of helicopters. Rotor (3, 3') of copter (1) comprises drive shaft (10) to run about first axis (A), rotor hub (11) to run integral with drive shaft (10) about said axis (A) and several blades (12) extending from said hub (11) on opposite side from said axis (A) and along appropriate second axis (B) perpendicular to first axis (A). Every blade (12) can displace relative to hub (11) and other blades (12) about appropriate third axis (C) perpendicular to appropriate second axis (B), Said screw (3, 3') incorporates several oscillation dampers (40) for appropriate blade (12) relative to appropriate third axis (C) including appropriate first part (41) displacing integral with blade (12) about said axis (C). Damper (40) comprises appropriate second parts (42, 46a, 46b) articulated with appropriate parts (41) and functionally engaged therewith.
EFFECT: simplified design and servicing.
