Hubs, rotors and drones

Abstract

A rotor hub, rotor, and unmanned aerial vehicle (UAV) include a main body with a oscillation axis around which it can oscillate. The main body includes at least two mounting positions, located on either side of the oscillation axis, for mounting rotor blades. With the rotation center of the main body as the center, the rotation angle from the mounting position to the oscillation axis along the rotation direction of the main body satisfies 30°≤R≤60°. The rotor hub provided by this invention performs floating oscillation while actively correcting the pitch angle of attack, achieving lift complementarity, reducing vibration, thereby improving flight stability, extending component lifespan, reducing the computational burden on the flight controller, and reducing noise.
