FIELD: aircraft engineering. ^ SUBSTANCE: invention relates to aircraft engineering, namely, to helicopter rotor hubs. Proposed rotor hub consists of a spider with arms attached thereto. Aforesaid arms consists of arm axle, strut sleeves, rubber damper, thrust bearings and yoke with dog and blade. Aforesaid spider rests upon the drive shaft via spherical hinge. Note that torque is transmitted with the help of drive rod made up of upper and lower casings, shaped plates and journals. Aforesaid strut sleeve has the aligned horizontal hinge that allows a rated offset of arm axle from the rotor rotational axis, rotor taper angle and vertical offset of aforesaid aligned horizontal hinged relative to rotor taper apex. Aforesaid sleeve can be adapted for rotor with whatever number of blades. ^ EFFECT: hub of rotor with whatever number of. ^ 2 dwg
