Abstract
An axially symmetric turbojet-engine exhaust nozzle which is directable as a unit. The exhaust nozzle is situated downstream of an exhaust duct (,) fitted with a spherical wall (,). A single control ring (,) driven by linear actuators (,) allows regulation of the nozzle cross section and direction. Converging flaps (,) are guided on an upstream side by the spherical wall (,) and are supported at a downstream side by a control lever (,) which hinges on the control ring (,) and rests upstream on an external surface (,) of the spherical wall (,). Diverging flaps (,) hinge on the converging flaps (,) to form an inner ring of hot flaps. The diverging flaps (,) are situated downstream in an extension of the converging flaps (,) and further hinge on an outer ring of cold flaps (,), which in turn hinge on the control ring (,). A synchronizing system connects upstream ends of the control levers (,) to the control ring (,) and ensures self-centering of the control ring (,), the outer ring of cold flaps (,) and the inner ring of hot flaps relative to the spherical wall (,).
