1. An apparatus for use with a duct that channels a fluid therethrough, said apparatus comprising: a ballistic containment layer configured to be exposed to the fluid, wherein said ballistic containment layer mates against the 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; andan insulation layer positioned between said first and second air containment layers; anda vent defined through said first air containment layer, said second air containment layer, and said insulation layer. 2. The apparatus according to claim 1 further comprising an outer ballistic containment layer substantially circumscribes said insulation sheath. 3. The apparatus according to claim 1, wherein said ballistic layer comprises a fiberglass weave of S-glass fibers. 4. The apparatus according to claim 1, wherein said first and said second air containment layers encapsulate said insulation layer to substantially isolate said insulation layer from fluid flowing from the duct through the fracture. 5. The apparatus according to claim 1, wherein said first and said second air containment layers are formed from a temperature-resistant material that is substantially impermeable to fluid flowing from the duct through the fracture. 6. The apparatus according to claim 1 further comprising a releasable fastener coupled to said second air containment layer. 7. 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; andforming 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; andcoupling the ballistic containment layer to the insulation sheath such that the insulation sheath circumscribes said ballistic containment layer. 8. The method of claim 7, wherein forming a ballistic containment layer comprises forming a ballistic containment layer from a temperature resistant material that is permeable to enable the fluid to flow therethrough. 9. The method of claim 8, wherein forming a ballistic containment layer comprises forming a ballistic containment layer from a fiberglass weave of S-glass fibers. 10. The method of claim 7, wherein forming the first and second air containment layers comprises forming the first and second air containment layers from a temperature resistant material that is substantially impermeable to prevent the fluid from flowing therethrough. 11. The method of claim 10, wherein forming the first and second air containment layers comprises forming the first and second air containment layers from one of silicone rubber or silicone coated fiberglass. 12. The method of claim 7, wherein forming the insulation sheath comprises encapsulating the insulation layer between the first and second air containment layers to substantially isolate the insulation layer from the fluid flowing from the duct through the fracture. 13. A duct protection system for a vehicle, said system comprising: a duct configured to channel a fluid therethrough; anda 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; andan insulation layer positioned between said first and second air containment layers; anda vent defined through said first air containment layer, said second air containment layer, and said insulation layer. 14. The duct protection system according to claim 13, wherein said ballistic containment layer is permeable to enable the fluid flow to pass therethrough. 15. The duct protection system according to claim 13, wherein said first and said second air containment layers are formed from a temperature-resistant material that is impermeable to the fluid flow from the fracture, wherein said first and said second air containment layers substantially encapsulate said insulation layer to prevent exposure of said insulation layer to the fluid flowing from said duct through the fracture.
