Zusammenfassung:Methods and systems for duct protection of a vehicle, e.g. an aircraft, are provided. The methods and systems provided include an apparatus for directing flow discharged from a facture in a duct. The apparatus includes a ballistic containment layer 202, an air containment layer 204 substantially surrounding the ballistic containment layer, and a vent 210 defined in the ballistic containment layer 202 and the air containment layer 204. The vent 210 is configured to direct a flow discharged from the duct fracture. It can further comprise an insulation layer 206 in contact with the duct or integrated in one of the ballistic containment layer 202 or air containment layer 204. An anti-rotation feature can be used to retain a tab coupled to the duct. The ballistic containment layer comprises at least one of a ceramic fiber, para-aramid fiber and a carbon fiber.
