A duct includes a rigid air-permeable tube of composite material. The duct also includes a layer of insulation coupled to an exterior surface of the rigid air-permeable tube. The duct further includes a non-rigid insulation layer in contact with the layer of insulation. The non-rigid insulation layer forms an air-impermeable duct wall.

Sound absorbing duct for environmental control system

A system includes one or more distribution nozzles associated with a seat within an internal space, and a return air grill associated with the seat. Airflow is directed from the one or more distribution nozzles toward and into the return air grill. A method includes associating one or more distribution nozzles with a seat within an internal space, associating a return air grill with the seat, and directing airflow from the one or more distribution nozzles toward and into the return air grill.

Ventilation systems and methods for internal cabins of vehicles

An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer High Efficiency Particulate Air (HEPA) media. The apparatus further includes a plurality of ultraviolet light transmissive strands that each have distal ends disposed in a spaced apart manner in an interface region between the outer HEPA media filter and an inner activated carbon filter or HEPA filter, and proximal ends connectable to an ultraviolet light emitting source such that ultraviolet light is transmitted by the transmissive strands into the interface region. The transmissive strands are configured to receive emitted ultraviolet light that is substantially between 222 nm and 265 nm for irradiating air passing through the filter.

Described herein are noise attenuating ducts and vehicles using these ducts for environmental control systems. A duct comprises an exoskeleton structure and a sound-absorbing structure, disposed within and conforming to the exoskeleton structure. The exoskeleton structure provides external mechanical support to the sound-absorbing structure thereby helping to maintain the tubular shape of the sound-absorbing structure. This external support does not interfere with the airflow inside the sound-absorbing structure. Furthermore, the external positioning of the exoskeleton structure allows the integration of various support mounting features for the installation of the duct in a vehicle. In some examples, the exoskeleton structure comprises a plurality of enclosed openings to reduce the weight of the exoskeleton structure and provide additional flexibility. Furthermore, additive manufacturing of the exoskeleton structure allows achieving a monolithic structure with various features and characteristics described above.

A system includes an outflow vent that has a cap releasably mounted to a panel within an internal cabin of a vehicle. The cap is elongated from a first end of the cap to a second end of the cap opposite the first end. The cap has a base wall that is overlaid on the panel and defines at least one slot therethrough. The cap receives an airflow generated by an airflow generator, and the at least one slot emits the airflow from the cap to form an air curtain within the internal cabin.

An environmental control system for use in an aircraft includes at least one component positioned along a length of the aircraft and a decompression panel assembly comprising an array of apertures. The array of apertures is based on a location of the decompression panel assembly along the length of the aircraft relative to the at least one component.

An apparatus for irradiating air flow in a vehicle includes a filter unit configured to couple to a recirculating-air conduit connected to a manifold of an air circulation system, the filter unit having an inlet end, and a filter disposed in the inlet end of the filter unit, including an outer wall of filter media having a shape that defines an interior volume of the filter. The apparatus further includes an ultraviolet light disposed on an end plate, configured to be mounted with the ultraviolet light positioned in the interior volume of the filter and the end plate against an open end of the filter. The ultraviolet light is configured to emit ultraviolet radiation substantially at between 222 nm and 265 nm for irradiating air flow through the filter into the air circulation system.

A galley cart system employs a dry ice compartment and a refrigeration compartment in a galley cart in flow communication with the dry ice compartment. A ventilation system is in interruptible flow communication with at least the refrigeration compartment and configured to receive gas discharged from at least the refrigeration compartment.

A cap for closing an open end of a duct tube has a cylindrical side wall having a length between a closed end and an open end of the side wall. An end wall extends across the closed end of the side wall. A conical section of the side wall extends outwardly from the open end of the side wall and has an interior surface configured to guide an end of a duct tube into a hollow interior volume of the side wall. A groove in an interior surface of the side wall is configured to receive a bead around an end of a duct tube inserted through the conical section and into the hollow interior of the side wall. A plurality of pull tabs extend outwardly from the conical section and are configured to be manually pulled, pulling the cap over the end of the duct tube.

Cap having a low cost construction and a self retaining feature

Systems and methods for limiting infiltration of cabin air into the flight deck of an aircraft, where the systems include at least one upper nozzle disposed adjacent to and above an outer upper edge of a flight deck doorway and directed downwardly, and at least one lower nozzle disposed adjacent to and below an outer lower edge of the flight deck doorway and directed upwardly; a conduit system to deliver air from a flight deck air supply to the upper and lower nozzles; and an airflow controller configured to provide sufficient air flow from the flight deck air supply to the upper and lower nozzles to create directional airstreams across the gaps between the closed flight deck door and the upper and lower edges of the flight deck doorway, so that the airstreams limit infiltration of cabin air into the flight deck via the gaps.

An aircraft air distribution assembly providing integrated personally controllable air flow and cabin air flow is presented. The aircraft air distribution assembly comprises a plenum and a flow restriction system. The plenum is connected to a plurality of personal air outlets configured to provide the personally controllable air flow. The flow restriction system extends through at least one wall of the plenum, the flow restriction system configured to set a pressure for the cabin air flow.
