Abstract: Disclosed is a system comprised of different points-of-presence (“PoPs”) that provide software defined hybrid private and public networking for different entity sites. A system PoP may establish and/or maintain different network circuits for accessing different destinations or services. The system PoP may receive a tunnel creation request from a particular site, may obtain entity-defined policies that are specified for the particular site, and may establish a particular network tunnel to the particular site. The system PoP may then route egress traffic with a first classification through a first network circuit with a different quality of service (“QoS”) than egress traffic with a second classification according to the policies. Similarly, the system PoP may route ingress traffic arriving over the first network circuit through the particular network tunnel with a different QoS than ingress traffic arriving over the second network circuit according to the policies.

Abstract: A method and device are described for determining input regions that are affected by a user input at a graphical user interface, GUI. For each input region, the following are associated with one another: (i) an actuation level of the input region, (ii) an allocation of the input region to a region of the GUI, and (iii) a blocking type of the input region. The method includes detecting a user input, wherein the user input is allocated an input position on the GUI. The method additionally includes determining at least one input region that contains the input position. Finally, the method includes evaluating the blocking type allocated to that input region in order to determine whether the user input to at least one lower-ranking input region that contains the input position is blocked.

Abstract: A method of fabricating a bonded cascade assembly of a thrust reverser for an aircraft nacelle. The method may include inserting individual turning vanes between spaced apart elongated stiffeners at an aft end thereof and sliding the turning vanes toward a front frame piece attached to or integrally formed with forward ends of the elongated stiffeners. The elongated stiffeners may have inner and outer flanges for trapping and limiting radial movement of the turning vanes. The method may further include bonding the turning vanes to the structural frame with a structural adhesive and attaching a closeout cap to the aft ends of each of the elongated stiffeners.

Abstract: A method and aerodynamic device for modifying at least one vane of a cascade thrust reverser. One or more of the aerodynamic devices may be formed and attached to forward-facing surfaces of vanes of the thrust reverser. The aerodynamic device may include a first side shaped to rest flush against at least a portion of the forward-facing surface of the vane, a second side opposite of the first side, a ledge portion protruding from the first side and configured to rest flush against a blunt leading edge of the vane, a rounded first end portion extending from the ledge portion to the second side of the aerodynamic device, and a second end opposite of the first end portion at which the first side and the second side converge. The aerodynamic device changes the size and contour of airflow channels between the vanes, increase the efficiency of the thrust reverser.

Abstract: Latch beams and hinge beams of an aircraft thrust reverser and a method for manufacturing the beams. The latch and hinge beams may comprise a plurality of hollow composite tubes joined with a plurality of machined metal fittings in alternating succession. The metal fittings may comprise at least one of hinge fittings and latching fittings. The latch and hinge beams may further comprise slider tracks configured to slidably attach to a translating sleeve of the thrust reverser. The hinge beams may each be rotatably attached to an engine strut or pylon of the aircraft, and the latch beams may each be mechanically latched with each other. Each of the latch and hinge beams may also be fixedly attached to an inner engine cowling of the thrust reverser.

Abstract: A thrust reverser comprises a translating sleeve, a torque beam, a plurality of cascades, a plurality of blocker doors, and a plurality of actuators. The translating sleeve is positioned at the rear of an aircraft nacelle and is translated rearward during thrust reverser deployment. The torque beam is positioned within the nacelle and configured to prevent airflow into the nacelle during thrust reverser deployment. The plurality of cascades are positioned around the circumference of the torque beam during thrust reverser stowage and are translated rearward during thrust reverser deployment. The plurality of blocker doors are positioned in alignment with the plurality of cascades and direct airflow through the plurality of cascades during thrust reverser deployment. The plurality of actuators are coupled to the forward edge of the sleeve and configured to translate the sleeve rearward during thrust reverser deployment.

Abstract: A protective cap for a rotatably-adjustable electrical component mounted to a PW board in an enclosed electronic control unit. The housing of the electronic control unit has a tuning access hole axially aligned with a tapered lead-in port in the center of the protective cap. An adjustment tool is inserted into the tuning access hole and guided into a tuning slot in the adjustable electrical component by the tapered lead-in port in the cap. The cap also protects the rotatable component from damage by a poorly-aimed adjustment tool. The several caps covering the rotatable components on a board as well as the access openings of the housing may be color-coded to assist in component identification.
