Abstract
The embodiments of the present invention disclose a rotor driving system, wherein at least three first actuators can drive a nonrotating lower-rotor swashplate to tilt towards a specific direction by cooperating with each other such that a rotating lower-rotor swashplate, lower tilted-arm pull rods and blade-clamp tilted arms of the lower rotor are all in motion, thereby driving first blade clamping bodies to be twisted relative to a lower rotor hub; at least three second actuators can drive a nonrotating upper-rotor swashplate towards a specific direction by cooperating with each other such that a rotating upper-rotor swashplate, upper-rotor steering rod—L arms, lower upper-rotor steering rods, pull rods, upper upper-rotor steering rods, upper tilted-arm pull rods, blade-clamp tilted arms 42 of the upper rotor are all in motion, thereby driving a second blade clamping body to be twisted relative to an upper rotor hub. Thus, in the solution, the structure of a rotor driving system is simplified, thus solving the problems of a low production efficiency of the process and of inconvenient testing and maintenance.
