A compound rotor system of wind powered engine has a pilot rotor unit working at low wind speed condition and a main rotor unit working at high wind speed condition. The rotor units are connected to a main shaft through independent clutch devices, so that a controllable rotating detachable transmission relationship is formed between the rotors and the main shaft. By properly switching of the clutch devices, not only a greater starting torque of the wind powered engine is achieved at low wind speed condition, but also the advantage of the main rotor unit at high wind speed condition with excellent wind capturing efficiency is given full play, and the range of speed and region for wind powered engine is enlarged.

L'invention concerne un système de rotor composite de moteur éolien, comprenant une unité rotor pilote fonctionnant dans des conditions de faible vitesse de vent et une unité rotor principale fonctionnant dans des conditions de haute vitesse de vent. Les unités rotors sont reliées à un arbre principal par l'intermédiaire de dispositifs d'embrayage indépendants, de façon qu'une relation de transmission séparable rotative contrôlable soit créée entre les rotors et l'arbre principal. Le changement approprié de dispositif d'embrayage permet non seulement d'obtenir un plus grand couple de démarrage du moteur éolien dans des conditions de faible de vitesse de vent, mais également d'exploiter pleinement l'excellente efficacité de capture du vent inhérente à l'unité rotor principale dans des conditions de haute vitesse de vent, la plage de vitesses et de zones pour le moteur éolien étant élargie.
