Abstract

L'invention propose des perfectionnements aux turbomachines et hélices à réglage rotorique. L'organe moteur de réglage est embarqué dans le rotor et l'énergie lui est fourni par la machine d'entraînement principale. Cette énergie est transférée soit par circulation ou mise en pression d'un fluide, soit par induction électrique. Applicable aux turbomachines et hélices.
