    Abstract: 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.

    Abstract: 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.
