Abstract: An axisymmetric, converging-diverging and swiveling exhaust nozzle includes converging flaps (3) driven by an axially displaceable drive ring (7). The diverging flaps (15) are connected by linkrods (20) to a pivoting ring (21). The pivoting ring (21) is mounted in swiveling manner on a spherical segment (30) fixedly joined to the structure (13). In an embodiment variation, the spherical segment (30) is mounted by a sliding connection on the stationary structure. A rotation-blocking system (33) precludes the rotation of the spherical segment (30) about the axis X of the turbojet engine.
