Abstract

Turbomachine à déplacement de fluide comportant au moins un rotor principal (1), caractérisée par le fait qu'elle comporte un rotor auxiliaire (13), à flux axial à aubages profilées (15) et à rotation indépendante de celle du rotor principal, disposé dans une veine fluide axiale (10), soit en amont du rotor principal pour communiquer une prérotation au fluide, soit en aval de celui-ci pour modifier une rotation éventuellement existante de ce fluide, avec un moyen (17) pour modifier la vitesse de ce rotor auxiliaire.
