Aspects of the disclosure regard an exhaust nozzle for a gas turbine engine that includes an outer nozzle wall, a flow channel which is limited radially outwards by the nozzle wall, a centerbody arranged in the flow channel, and at least two struts connecting the centerbody to the nozzle wall. One of the struts is connected to the nozzle wall by a first connection, the first connection constraining movement of the strut relative to the nozzle wall in the radial direction and in the circumferential direction. The at least one other strut is connected to the nozzle wall by a second connection, the second connection constraining movement of the strut relative to the nozzle wall in the circumferential direction but allowing movement of the strut relative to the nozzle wall in the radial direction.

An exhaust nozzle for use with a gas turbine engine includes an outer shroud, an inner plug spaced radially apart from the outer shroud, and at least one support vane that is coupled to the outer shroud. The outer shroud and the inner plug cooperate to provide an exhaust nozzle flow path therebetween. The at least one support vane interconnects the outer shroud and the inner plug to support the inner plug in the exhaust nozzle flow path.

A variable 3D CD nozzle includes: a flexible body defining a flow path having an inlet extending through a narrowed throat to an expanded outlet, wherein the flexible body comprises a plurality of flexible members movably interconnected together; and at least one means for changing a shape of the flexible body to change a dimension or location of the throat plane relative to at least one of the inlet plane or outlet plane. A method of changing airflow in a nozzle includes operating at least one means for changing the shape of the flexible nozzle body to change the dimension or the location of the throat plane. A method of testing an object includes placing a test object in the test region of the test cell and passing a test gas from the outlet opening of the nozzle onto the test object.

An exhaust nozzle of a gas turbine engine which includes an outer nozzle wall, a flow channel which is limited radially outwards by the nozzle wall, a centerbody arranged in the flow channel, and exactly one strut connecting the centerbody to the nozzle wall. The strut is connected to the nozzle wall by means of a connecting structure that is displaceable in the axial direction of the outer nozzle wall. At least one actuator is provided interacting with the connecting structure or the outer nozzle wall for displacing the strut in the axial direction.

A bypass turbojet nacelle comprising a fixed structure, a fixed cowl and a cowl movable in translation between advanced and withdrawn positions by a ram with a reverser flap movable thereon, and a deployment system comprising a first slider integral with the movable cowl, a first groove comprising a first part and a curved, second part integral with the fixed structure, a second slider movable in translation in the second groove part, a first connecting rod rotatable on the first slider and on the second slider, and a second connecting rod articulated on both the first connecting rod first end and the reverser flap. The ram rod is articulated on the first connecting rod. Moving the first slider from the advanced to the withdrawn position moves the second slider along the first part and, when the first slider reaches the withdrawn position, the second slider moves along the second part.

An exhaust nozzle of a gas turbine engine which includes a nozzle wall, the nozzle wall including an upstream, fixed structure and a downstream, translatable structure that is translatable relative to the fixed structure, a flow channel which is limited radially outwards by the nozzle wall, a centerbody arranged in the flow channel, at least one strut connecting the centerbody to the nozzle wall, a thrust reverser unit that comprises blocking doors, a first actuation system for deployment of the blocking doors into a deployed position for thrust reversal, and a second actuation system for translating the translatable structure between a stowed, upstream position and a fully deployed, downstream position. It is provided that the at least one strut is connected to the fixed structure, that the blocking doors are connected to the translatable structure, and that the first actuation system and the second actuation system are independent actuation systems.
