摘要：
The present invention relates to a main rotor arrangement (1) for an UAV-helicopter, comprising a rotor mast (3) defining a vertical axis of rotation (R), and a hub (5) for attachment of rotor blades, wherein the hub (5) is mounted to the rotor mast (3) in a tiltable way so as to reduce loads acting on the rotor blades during operation of the UAV-helicopter. The main rotor arrangement (1) comprises a damping assembly (18) for damping said tilting of the hub (5).
