The invention relates to a unit comprising a hydraulic turbine (1), a duct (5) leading a forced flow of water to the turbine, a duct (8) discharging the outgoing flow from the turbine and vanes (20) for guiding the flow through the discharge duct. Each guide vane (20) is able to rotate about an axis (x22) secant to the wall (84) of the discharge duct. Means (30) are provided for controlling the angular position of the vane (20) about its axis of rotation (x22). Each guide vane (20) can also be retracted into the wall (84) of the discharge duct (8), and means (21) are provided for adjusting the extent to which they are withdrawn into the wall.
L'invention concerne une installation comprenant une turbine hydraulique (1), un conduit (5) d'amenée à la turbine d'un écoulement forcé d'eau, un conduit (8) d'évacuation de l'écoulement sortant de la turbine et des ailettes (20) de guidage de l'écoulement dans le conduit d'évacuation. Chaque 22) sécant à la paroi (84) du conduit d'évacuation. Des moyens (30) sont prévus pour commander la position angulaire de l'ailette (20) autour de son axe de rotation (X22). Chaque ailette de guidage (20) est également rétractable dans la paroi (84) du conduit d'évacuation (8) et des moyens (21) de réglage de son enfoncement dans la paroi sont prévus.
