Abstract

L'invention concerne un aérogénérateur dans lequel, pendant la période de démarrage, le calage d'au moins une partie des pales de son hélice est modifié en fonction de la vitesse de rotation de l'hélice. L'invention est remarquable par le fait que l'aérogénérateur comprend des moyens agencés pour, sous l'action de la variation du calage d'au moins une pale, déplacer en translation une tige de commande des organes d'accouplement de l'aérogénérateur. L'invention permet de pouvoir commander l'embrayage de l'aérogénérateur directement à partir de son hélice.
