摘要
A carrier structure for a rotor and a method of preventing the coupling of the vibration modes of a carrier structure of a flying machine with the vibration modes of a rotor are provided. The carrier structure has an airframe and a mounting structure suitable for being engaged with the rotor. A vibration-damper mechanism is fitted to the mounting structure and has a resonator that includes a weight element, a damper, and a first deformable member. The weight element is a flapping weight element and is carried by the mounting structure via the first deformable member. The first deformable member allows the weight element to move with respect to the mounting structure and restrains the mobility of the weight element. The damper is interposed between the weight element and the mounting structure for damping the movement of the weight element.
