Abstract
A flow-straightening stator is fixed into the duct downstream of the rotor mounted so that it rotates in this duct, and includes vanes with aerodynamic profile which straightens out the airflow downstream of the rotor substantially along the axis of the duct, and are each inclined to the radial direction, from the axis of the duct towards its periphery, and in the opposite direction from the direction of rotation of the rotor, and/or inclined at a slant, from the center of the duct to its periphery and from upstream to downstream of the duct.
