  • Publication number: 20240125286
    Abstract: 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.

  • Patent number: 5141266
    Abstract: A sliding door rotary latch system includes a handle assembly mounted on the sliding door adjacent its leading edge, a rotary latch assembly and locking mechanism mounted on the front post of the door frame cooperating with a strike bar on the handle assembly selectively to latch the sliding door in its fully closed position and a rear latch plate mounted on the back post of the door frame cooperating with the handle assembly selectively to latch the sliding door in its fully open position. The door mounted handle assembly includes an outer pivotal handle, an inner pivotal handle, and an inner actuation mechanism operative to allow either handle independently of the other to actuate either a pivotal front cam actuator arm or a rear pivotal latch independent of the other. Either handle may be held in its pivoted position toward the direction of sliding movement of the door during that sliding movement without adversely effecting the latching action when the door is either fully closed or opened.
