A scalable cargo-fire-suppression agent distribution system and method is disclosed. A supply source unit subset of a set of fire-suppression agent supply source units is selected based on an operation condition to provide a selected supply source unit subset, and a fire-suppression agent from the selected supply source unit subset is distributed during the operation condition.

1. A method for scaling cargo fire-suppression agent distribution, comprising: detecting an operation condition;selecting a supply source unit subset of a set of fire-suppression agent supply source units to provide a selected supply source unit subset if the operation condition indicated a descent;
1. A method for scaling cargo fire-suppression agent distribution, comprising: detecting an operation condition;selecting a supply source unit subset of a set of fire-suppression agent supply source units to provide a selected supply source unit subset if the operation condition indicated a descent;discharging a fire-suppressant agent at a discharge rate directly from the selected supply source unit subset into a vehicle ducting; anddistributing the fire-suppression agent into a contained volume at the discharge rate from the selected supply source unit subset during the descent. 2. The method of claim 1, further comprising shutting off a supply of air to the contained volume if the operation condition indicated cruise. 3. The method of claim 1, further comprising reducing pressure in the contained volume if the operation condition indicated cruise. 4. The method of claim 1, wherein the discharge rate is fixed. 5. The method of claim 1, wherein the discharge rate is variable. 6. The method of claim 1, further comprising discharging the fire-suppressant agent directly into the contained volume. 7. The method of claim 1, wherein the contained volume comprises a Class E cargo compartment of an aircraft. 8. The method of claim 1, wherein the selected supply source unit subset comprises: at least one extra dedicated high rate discharge (HRD) descent storage source, at least one low rate discharge bottle, a descent storage bottle, or at least one dump bottle. 9. The method of claim 1, further comprising coupling the set of fire-suppression agent supply source units to the vehicle ducting. 10. The method of claim 9, further comprising coupling the vehicle ducting to the contained volume. 11. The method of claim 10, further comprising suppressing a fire within the contained volume. 12. The method of claim 10, wherein an aircraft comprises the contained volume. 13. The method of claim 1, wherein the set of fire-suppression agent supply source units comprise at least one member selected from the group consisting of: a storage bottle, an On-Board Inert Gas Generation System (OBIGGS), an HFC-125 supply source, a Pentafluoroethane (CF3CHF2) supply source, a Nitrogen supply source, an Argon supply source, a Helium supply source, an aerosolized liquid mist supply source, an FK 5-1-12 (C6F12O) supply source, a water supply source, and a Halon supply source. 14. A scalable cargo fire-suppression agent distribution system comprising: a set of fire-suppression agent supply source units coupled to a vehicle ducting;a plurality of distribution nozzles operable to distribute a fire-suppression agent during a descent; anda controller operable to: shut off airflow to reduce a flow of oxygen to a contained volume coupled to the vehicle ducting during cruise such that a fire is suppressed, and select a supply source unit subset of the set of fire-suppression agent supply source units such that the fire-suppression agent is distributed at an increased flow rate therefrom directly into the vehicle ducting during the descent. 15. The system of claim 14, wherein: the controller is further operable to reduce pressure in the contained volume during cruise such that the fire is suppressed. 16. A method for scaling cargo fire-suppression agent distribution in an aircraft, comprising: shutting off airflow to reduce a flow of oxygen to a contained volume during cruise such that a fire is suppressed, wherein the contained volume is coupled to a ducting;selecting a supply source unit subset of a set of fire-suppression agent supply source units such that a high flow rate of a fire-suppression agent is distributed therefrom during a descent flight phase; anddistributing directly into the ducting the fire-suppression agent during the descent flight phase. 17. The method of claim 16, further comprising distributing the fire-suppression agent directly into the contained volume. 18. The method of claim 16, further comprising reducing pressure in the contained volume during cruise such that the fire is suppressed.
