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;de-pressurizing a contained volume if the operation condition indicated cruise;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 descent;discharging a fire-suppressant agent at a fixed discharge rate directly from the selected supply source unit subset into a vehicle ducting; anddistributing the fire-suppression agent into the contained volume at the fixed discharge rate from the selected supply source unit subset during the descent. 2. 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, or at least one low rate discharge bottle. 3. The method of claim 1, further comprising coupling the set of fire-suppression agent supply source units to the vehicle ducting. 4. The method of claim 3, further comprising coupling the vehicle ducting to the contained volume. 5. The method of claim 4, further comprising suppressing a fire within the contained volume. 6. The method of claim 4, wherein an aircraft comprises the contained volume. 7. 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; andthe operation condition comprises at least one member selected from the group consisting of: takeoff, climb, the cruise, the descent, landing, a cargo smoke condition, a cargo fire condition, and a cargo heat condition. 8. The method of claim 1, further comprising discharging the fire-suppressant agent directly into the contained volume. 9. The method of claim 1, wherein the contained volume comprises a Class E cargo compartment of an aircraft. 10. The method of claim 1, further comprising: discharging the fire-suppressant agent without using a flow rate control valve; anddistributing the fire-suppression agent only during the descent. 11. 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 first fire-suppression agent and a second fire-suppression agent during a first operation condition and a second operation condition respectively; anda controller operable to: select a first fire-suppression agent supply source unit subset such that a continuous low flow rate of the first fire-suppression agent at a first fixed discharge rate is distributed therefrom directly into the vehicle ducting during the first operation condition; andselect a second fire-suppression agent supply source unit subset such that an increased flow rate of the second fire-suppression agent at a second fixed discharge rate is distributed therefrom directly into the vehicle ducting and a combined flow rate of the first fire-suppression agent and the second fire-suppression agent is increased during the second operation condition. 12. The system of claim 11, wherein: a contained volume is coupled to the vehicle ducting;the first operation condition comprises cruise;the second operation condition comprises descent; andthe controller is further operable to: shut off airflow to reduce a flow of oxygen to the contained volume during the cruise such that a fire is suppressed; andselect the second fire-suppression agent supply source unit subset such that a flow rate of the second fire-suppression agent is distributed during only the descent. 13. The system of claim 11, wherein: the first fire-suppression agent supply source unit subset and the second fire-suppression agent supply source unit subset are selected based on at least one member selected from the group consisting of: a pilot input, a user input, and a parameter from a database, andthe controller is further operable to: shut off the first fire-suppression agent supply source unit subset such that discharging the first fire-suppression agent stops; andturn on the second fire-suppression agent supply source unit subset such that discharging the second fire-suppression agent starts. 14. The system of claim 11, wherein the second fire-suppression agent supply source unit subset comprises at least one of: a descent storage bottle, a descent bottle, a low rate discharge bottle, and a dump bottle. 15. The system of claim 11, further comprising distributing the first fire-suppression agent and the second fire-suppression agent without using a flow rate control valve. 16. A method for scaling cargo fire-suppression agent distribution in an aircraft, comprising: selecting a first fire-suppression agent supply source unit subset such that a continuous low flow rate of a first fire-suppression agent is distributed therefrom during cruise flight phase;selecting a second fire-suppression agent supply source unit subset such that a high flow rate of a second fire-suppression agent is distributed therefrom during descent flight phase; anddistributing directly into a ducting the first fire-suppression agent at a first fixed discharge rate and the second fire-suppression agent at a second fixed discharge rate during the cruise flight phase and the descent flight phase respectively. 17. The method of claim 16, further comprising: coupling a contained volume to the ducting;shutting off airflow to reduce flow of oxygen to the contained volume during the cruise such that a fire is suppressed; andselecting the second fire-suppression agent supply source unit subset such that the second fire-suppression agent at the second fixed discharge rate is distributed during only the descent. 18. The method of claim 16, further comprising distributing the first fire-suppression agent and the second fire-suppression agent directly into a contained volume. 19. The method of claim 16, further comprising distributing the first fire-suppression agent concurrently with the second fire-suppression agent during the descent. 20. The method of claim 16, further comprising distributing the first fire-suppression agent and the second fire-suppression agent without using a flow rate control valve.
