Abstract
An exhaust nozzle of a gas turbine engine includes an outer nozzle wall, a centerbody arranged in a flow channel, and two struts connecting the centerbody to the wall. A first strut is connected to the wall by a first connection allowing movement of the strut relative to the nozzle wall in the axial direction. Another strut is connected to the wall by a second connection allowing movement of the strut relative to the wall in the radial and axial directions. The second connection is formed by a sliding element and a receiving slot, wherein the sliding element includes an interaction zone interacting with an actuator for axial movement. The interaction zone has a radial length such that the interaction between the actuator and the interaction zone is maintained when the sliding element is moved in the radial direction by radial thermal expansion of the strut and/or the centerbody.
