  • Publication number: 20050126174
    Abstract: An exhaust nozzle includes an exhaust duct with an outlet and a row of radial apertures upstream therefrom. A radial frame surrounds the duct upstream from the apertures. A row of flaps are hinged to the frame to selectively cover and uncover the apertures for controlling exhaust flow discharged therethrough. An arcuate unison bar surrounds the duct adjacent to the frame and includes circumferentially spaced apart cams engaging corresponding cam followers affixed to the flaps. An actuator is joined to the bar for selective rotation thereof between opposite first and second directions to pivot open and closed the flaps atop the apertures.

  • Patent number: 6895742
    Abstract: A fan thrust reverser includes an outer louver door joined to an inner blocker door by a drive link in a bifold configuration. The louver door is stowed closed in the outer skin of a fan nacelle outside the blocker door stowed closed in the inner skin of the nacelle. An actuator deploys open the louver and blocker doors, with the louver door extending radially outwardly and the blocker door extending radially inwardly for reversing fan exhaust flow during thrust reverse operation.

  • Publication number: 20050102996
    Abstract: A thrust reverser includes reverser doors pivotally mounted in a nacelle. Each door includes a latch pin mounted at a distal end thereof. A complementary latch hook is pivotally mounted in the nacelle for engagement with the pin to latch closed the reverser door. A rotary retainer adjoins the hook for blocking rotation of the hook to latch closed the door, and selectively unblock rotation of the hook to permit the pin to disengage the hook.

  • Publication number: 20050086927
    Abstract: A turbofan nacelle includes forward and aft cowls adjoining at a joint, and including an exhaust duct having a main outlet for discharging exhaust. A variable nozzle surrounds the exhaust duct and includes a secondary outlet around the main outlet. A thrust reverser bridges the forward and aft cowls upstream from the variable nozzle. The variable nozzle is inductively powered and controlled across the closed joint, and is uncoupled inductively from the forward cowl when the joint is open.

  • Publication number: 20050039437
    Abstract: A turbofan exhaust nozzle includes a fan duct defined between a fan nacelle and core engine cowling. The duct includes an arcuate outlet at the trailing edge of the nacelle. A movable flap is disposed in a minor portion of the fan duct, with a remaining major portion of the fan duct having a constant flow area. The flap may be moved between stowed and deployed positions to locally decrease flow area inside the duct for noise attenuation.

  • Publication number: 20050039438
    Abstract: A fan thrust reverser includes a nacelle having radially outer and inner skins. An outer door is disposed in the outer skin, and mounted to the nacelle at a hinge joint. A toggle link is pivotally joined between the outer door and the nacelle for latching stowed the outer door in the nacelle. An actuator is provided for rotating the outer door about the hinge joint for deploying the door outwardly from the nacelle and toggling off the toggle link, and stowing inwardly the outer door upon reverse rotation thereof and toggling on the toggle link to latch the door stowed in the nacelle.

  • Patent number: 6845607
    Abstract: A center plug is configured for variable area use in an exhaust nozzle. A forward portion of the plug includes an inlet having a closing flap therein, and an aft portion of the plug includes an outlet. The flap is selectively open during aircraft takeoff operation and up to a preset climb altitude for bypassing a portion of core exhaust flow through the plug, with the flap being closed from preset altitude and cruise operation. Opening the flap correspondingly increases the available flow area for discharging the exhaust flow for reducing velocity thereof, and attenuating noise.

  • Patent number: 6845946
    Abstract: A thrust reverser includes forward and aft louvers pivotally mounted in a compartment defining a flow tunnel through the outer and inner skins of a fan nacelle. An aft flap is integrally joined to the aft louver for rotation therewith. A unison link joins together the forward and aft louvers. And, an actuator is joined to the louvers for rotation thereof between a stowed position in which the louvers and flap are closed in the nacelle skins and a deployed position in which the louvers and flap are pivoted open from the skins.

  • Patent number: 6820410
    Abstract: A turbofan exhaust nozzle includes a fan duct defined between a fan nacelle and a core engine cowling. The fan duct includes a longitudinal endwall and a partition spaced therefrom to define a secondary flow duct. The fan duct also includes a primary outlet, and the secondary duct includes a secondary outlet. The partition between the two ducts includes an aperture covered by a selectively movable flap.

  • Patent number: 6751944
    Abstract: A gas turbine engine exhaust nozzle includes coaxial inner and outer conduits. The inner conduit has a main outlet at an aft end thereof, and a row of radial apertures spaced upstream from the outlet. The outer conduit has an auxiliary outlet at an aft end thereof, and surrounds the inner conduit over the apertures to form a bypass channel terminating at the auxiliary outlet. A plurality of flaps are hinged at upstream ends thereof to selectively cover and uncover corresponding ones of the apertures and selectively bypass a portion of exhaust flow from the inner conduit through the outer conduit in confluent streams from both the main and auxiliary outlets.

  • Patent number: 6688099
    Abstract: A turbofan exhaust nozzle includes a jet pipe having a pair of thrust reverser doors disposed on opposite sides thereof. Each door has a hinge arm joined to a swing arm, which in turn is joined to the pipe. Each door also includes a latching clip at a forward end, and a deployment clevis between the clip and hinge arm. A common actuator is connected to both doors by corresponding links joined to the clevises for driving the links aft to pivot aft the doors and swing arms. A first lock selectively locks the latching clip and a second lock selectively locks the swing arms in coordination with the first lock for permitting variable area axial movement of the doors, thrust reverser deployment thereof, and retraction to stowed positions of the doors.
