Bearingless Rotor Blades

As one of the significant symbols of the 4th-generation helicopter, bearingless rotors adopt the composite flexible beams, with hinges and bearings of the traditional rotors completed cancelled. The flapping, lead-lag, and feathering motions of blades rely on the propeller hub's support arms and elastic deformation of blades. Therefore, such blades feature high control efficacy, simple structure, low propeller hub drag, and excellent maintainability.
