Various non-limiting embodiments of a nozzle assembly for use with a propulsion system and a sleeve assembly for use with the nozzle assembly are disclosed herein. In a non-limiting embodiment, the nozzle assembly includes, but is not limited to, a nacelle. The nozzle assembly further includes, but is not limited to, a sleeve assembly mounted within the nacelle downstream of the engine. The sleeve assembly is configured to receive the mass flow from the engine and to guide the mass flow to an exit of the propulsion system. The sleeve assembly is comprised of a plurality of sleeve segments arranged in a circumferential configuration. Each sleeve segment of the plurality of sleeve segments has an elongate body that is longitudinally aligned with a longitudinal axis of the sleeve assembly.

Nozzle assembly for use with a propulsion system and sleeve assembly for use with the nozzle assembly

A nozzle assembly includes a sleeve defining a pathway, the sleeve disposed within a nacelle. The pathway and an internal surface of the nacelle guides a mass flow from an engine to an exit of the propulsion system. The sleeve is configured to move between a forward position an aft position within the nacelle aft of the engine. The sleeve has a protruding portion that extends towards a center of the pathway and that defines a smallest internal diameter of the sleeve. The sleeve includes a plurality of sleeve segments that are longitudinally aligned and circumferentially arranged to form the sleeve. The sleeve segments are configured to move circumferentially closer as the sleeve moves in a first direction within the nacelle and to move circumferentially further apart as the sleeve moves in a second direction within the nacelle. An actuator is coupled with, and is configured to move the sleeve.
