Abstract
A multiflow turbojet engine secondary flow adjusting device which includes annular vanes regularly distributed around the secondary duct. The vanes are movable about two fixed axes disposed between one half and one third of the height of the duct when the vane is in the active position. A control mechanism for the vanes are disposed within the interior of the duct and act on the axis of radial symmetry and at two-thirds of the height of the duct when the vane is in the active position. In the inactive position, the vane is parallel to the secondary air flow. The actuator and the fixed support axes form a modular assembly in accordance with another embodiment.
