Abstract: An exhaust assembly may include an exhaust body and a pivoting attachment feature. The exhaust body, such as a center body or a nozzle, may be configured to direct an annular exhaust stream exiting from a gas turbine engine. The pivoting attachment feature may be coupled the exhaust body and may be configured to pivotally couple the exhaust body to an engine flange. The pivoting attachment feature may be one of a plurality of attachment features circumferentially distributed around the exhaust body. The exhaust body may be a center body and the plurality of attachment features may be coupled to a radially inward surface the center body. The pivoting attachment feature may enable a degree of relative thermal expansion movement between the engine flange/turbine exhaust case and the exhaust body while mitigating detrimental thermal loads, according to various embodiments.
