Main rotor arrangement of an UAV-helicopter
Abstract:
A main rotor arrangement for an UAV-helicopter. A rotor mast defines a vertical axis of rotation. A hub is for attachment of rotor blades. The hub is mounted to the rotor mast in a tiltable way so as to reduce loads acting on the rotor blades during operation of the UAV-helicopter. A damping assembly is configured to damp the tilting of the hub.
Abstract(Chinese):

无人机直升机的主要转子装置。 转子桅杆定义了垂直的旋转轴。 轮毂用于安装转子叶片。 轮毂以可倾斜的方式安装到转子桅杆上，以便在无人机直升机的操作期间减少作用在转子叶片上的负载。 阻尼组件被配置成阻止轮毂的倾斜。
