Abstract: A vehicle includes an internal cabin having a main deck cargo compartment, and a barrier system within the internal cabin. The barrier system includes one or more flexible drapes moveable between an open position and a closed position. The barrier system is configured to selectively open and close the main deck cargo compartment from one more other areas of the internal cabin, and/or selectively open and close the main deck cargo compartment into separate areas.

Abstract: Described herein are zonal fire suppression systems and methods of using such systems for suppressing fires in cargo aircraft. A system is configured to individually monitor the temperature in each of multiple cargo zones in the cargo area. The system is also configured to selectively activate one or more of multiple zone distribution components to distribute a fire suppressant material, based at least on the temperature monitoring. The zonal approach to the temperature monitoring and to the fire suppressant material distribution allows reducing the fire suppressant material amount needed on the cargo aircraft, which, in turn, reduces the aircraft load. Furthermore, in some examples, the zonal approach eliminates unnecessary contact between the cargo (e.g., in the zones unaffected by fire) and the fire suppressant material. In some examples, this fire suppression involves depressurizing of the cargo area, in addition to or instead of the fire suppressant material distribution material.
