Apparatuses, systems, and methods comprising acoustically absorptive air ducts comprising an internally positioned structure component as an endoskeleton and an air impervious inner layer, and an acoustically absorptive foam outer layer, environmental control systems comprising such air ducts, and vehicles incorporating such environmental control systems are disclosed with methods for manufacture and installations are disclosed.

Acoustic air duct for environmental control system in vehicle

An aircraft includes an interior and an environmental system configured to circulate air through the interior. The aircraft also includes at least one disinfectant dispenser configured to dispense a disinfectant in the air circulated through the interior.

System and method for disinfecting an interior of an aircraft

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

Methods and apparatus to direct ventilation of vehicle occupants are disclosed. A disclosed example apparatus includes an air supply duct of a cabin of a vehicle, a manifold fluidly coupled to the air supply duct, the manifold to extend to occupant seats of the cabin, and nozzles fluidly coupled to the manifold, the nozzles to be positioned to face toward a front of a face of an occupant when the occupant occupies one of the occupant seats.

Methods and apparatus to direct ventilation of vehicle occupants

An aircraft including a fuselage having a side wall at least partially defining a passenger cabin and a crown section of the aircraft. The passenger cabin includes an overhead zone, a passenger zone, and a floor zone. An air supply duct is positioned within the crown section, and the air supply duct is configured to pressurize the crown section with air. At least one return air outlet is defined in the floor zone. An interior structure is coupled to the side wall and extends between the passenger cabin and the crown section. The interior structure includes a plurality of nozzles oriented to discharge the pressurized air from the crown section along an airflow path that extends downward through the overhead zone, downward through the passenger zone, and then towards the at least one return air outlet.

Air distribution system for use in an aircraft

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.

Ducts comprising exoskeleton and sound-absorbing structures and vehicles using such ducts

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.

Air curtain systems and methods for vehicle cabins

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.

Environmental control system for use in an aircraft

A duct includes a foam-filled honeycomb core structure having a tubular shape. The duct further includes an air-impermeable duct wall coupled to an exterior surface of the foam-filled honeycomb core structure.

Sound absorbing duct with foam-filled honeycomb core for environmental control system

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

A fluid flow restrictor device for controlling fluid flow at a connection between ducts may include a restrictor device body that is partially or fully inserted into and disposed within one of the ducts and an outboard restrictor device flange extending radially outward at an outboard end of the restrictor device body and having an outboard flange outer diameter that is greater than an inner diameter of the ducts so that the restrictor device body or the outboard restrictor device flange is engaged by an open end surface of the duct to prevent full insertion of the fluid flow restrictor device into the duct. A body inner surface defines a restrictor opening through the restrictor device body that can be varied to achieve desired fluid flow characteristics at the connection.

Fluid flow restrictor device

A composite duct with reinforcement comprises an inner ply, an outer ply, and a plurality of cellular core rings. The inner ply forms a channel with a circular cross-section. The plurality of cellular core rings is positioned at set intervals along a length of the composite duct and between the inner ply and the outer ply.

Composite duct with reinforcement

According to an embodiment, an aircraft comprises a fuselage including composite skin; an enclosure located inside the fuselage; a rechargeable battery disposed inside the enclosure; and a ventilation conduit extending from the enclosure to an opening in the composite skin, the ventilation conduit including: a first portion having a first end coupled to the enclosure and a second end spaced from the composite skin, and a second portion extending between the composite skin and the second end of the first portion, the second portion comprising an electrically non-conductive material.

Ventilation conduit for an aircraft

An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.

Light weight thermoplastic flex foam and hybrid duct system
