Systems and methods for duct protection of a vehicle

A method of fabricating an apparatus for containing a flow of fluid discharged from a fracture in a duct, said method comprising:

• forming a ballistic containment layer configured to be exposed to the fluid, wherein the ballistic containment layer mates against the duct;
• forming an insulation sheath, wherein the insulation sheath is configured to restrict heat transfer from within the duct, wherein forming the insulation sheath comprises:
• forming a first air containment layer;
• forming a second air containment layer;
• and
• forming an insulation layer positioned between the first and second air containment layers;
• forming a vent through the first air containment layer, the second air containment layer, and the insulation layer;
• and
• coupling the ballistic containment layer to the insulation sheath such that the insulation sheath circumscribes said ballistic containment layer.

A duct protection system for a vehicle, said system comprising:

• a duct configured to channel a fluid therethrough;
• and
• a duct burst apparatus comprising:
• a ballistic containment layer configured to be exposed to the fluid, wherein said ballistic containment layer mates against said duct;
• an insulation sheath coupled to said ballistic containment layer such that said insulation sheath circumscribes said ballistic containment layer, wherein said insulation sheath is configured to restrict heat transfer from within the duct, said insulation sheath comprising:
• a first air containment layer;
• a second air containment layer;
• and
• an insulation layer positioned between said first and second air containment layers;
• and
• a vent defined through said first air containment layer, said second air containment layer, and said insulation layer.
