A fire-suppression system for use in an aircraft having at least one cargo compartment is disclosed. Methods of suppressing a fire in the cargo compartment are also disclosed. The fire-suppression system, under one aspect of the present invention, can include at least one fire-suppressant vessel, at least one discharge conduit coupled to the at least one fire-suppressant vessel, and a valve arrangement coupled to the fire-suppressant vessel and the discharge conduit. The valve arrangement can have a first setting to discharge a fire suppressant at a first discharge rate after activation of the fire-suppression system, a second setting to discharge the fire-suppressant at a second discharge rate less than the first discharge rate, and a third setting to discharge the fire-suppressant at a third discharge rate greater than the second discharge rate during descent of the aircraft.

I claim: 1. A fire-suppression system for use in an aircraft having a cargo compartment, comprising: at least one fire-suppressant vessel; a discharge conduit coupled to the at least one fire-suppressant vessel; and a valve arrangement coupled to the at least one fire-suppressant vessel and the dis
I claim: 1. A fire-suppression system for use in an aircraft having a cargo compartment, comprising: at least one fire-suppressant vessel; a discharge conduit coupled to the at least one fire-suppressant vessel; and a valve arrangement coupled to the at least one fire-suppressant vessel and the discharge conduit, the valve arrangement having a first setting to discharge a fire suppressant to the cargo compartment at a first discharge rate upon activation of the fire-suppression system, a second setting to discharge the fire suppressant to the cargo compartment at a second discharge rate less than the first discharge rate, and a third setting to discharge the fire suppressant to the cargo compartment at a third discharge rate greater than the second discharge rate during descent of the aircraft. 2. The system of claim 1, further comprising a first pressurized container that contains at least a first portion of the fire suppressant, a second pressurized container that contains at least a second portion of the fire suppressant, and a third pressurized container that contains at least a third portion of the fire suppressant. 3. The system of claim 1 wherein the fire suppressant is Halon. 4. The system of claim 1 wherein valve arrangement is adjustable to provide at least the first, second, and third discharge rates of the fire suppressant. 5. The system of claim 1 wherein the valve arrangement includes a first flow control device coupled to the discharge conduit to control a flow of the fire suppressant at the second discharge rate, and a second flow control device coupled to the discharge conduit to control at least a portion of a flow of the fire suppressant for dispersal at the third discharge rate. 6. The system of claim 1 wherein the valve arrangement is configured to discharge the fire suppressant at the first discharge rate over a first period of time, to discharge the fire suppressant at the second discharge rate over a second period of time greater than the first period of time, and to discharge the fire suppressant at the third discharge rate over a third period of time less than the second period of time. 7. The system of claim 1 wherein the valve arrangement is configured to discharge the fire suppressant at the third discharge rate only during descent of the aircraft. 8. The system of claim 1 wherein the valve arrangement is configurable to discharge the fire suppressant into the cargo compartment at the second discharge rate to provide a fire suppressant concentration in the cargo compartment, and wherein the valve arrangement is configurable to discharge the fire suppressant into the cargo compartment at the third discharge rate to provide the fire suppressant concentration during the descent of the aircraft. 9. A fire-suppression system for use in an aircraft having a cargo compartment, comprising: a first vessel containing fire suppressant dischargeable into the cargo compartment during operation of the fire-suppression system; a first flow control device coupled to the first vessel and positioned to control a first flow of fire suppressant into the cargo compartment at a first discharge rate; a second vessel containing fire suppressant dischargeable into the cargo compartment; and a second flow control device coupled to the second vessel and positioned to control a second flow of fire suppressant into the cargo compartment along with the flow of fire suppressant from the first vessel, the first and second flows of fire suppressant being combined for simultaneous discharge into the cargo compartment at a second discharge rate greater than the first discharge rate during descent of the aircraft. 10. The system of claim 9 wherein at least a majority of the fire suppressant from the second vessel is discharged only during the descent of the aircraft. 11. The system of claim 9 wherein the fire suppressant is Halon. 12. The system of claim 9 wherein the first flow control device is activatable to discharge the fire suppressant from the first vessel over a first period of time, and the second flow control device is activatable to discharge the fire suppressant from the second vessel over a second period of time less than the first period of time. 13. The system of claim 9, further comprising a controller coupled to the first and second flow control devices, the controller being configured to activate at least the second flow control device to cause a generally continuous discharge of the fire suppressant from the second vessel during at least a majority of the descent of the aircraft. 14. A fire-suppression system for use in an aircraft having a cargo compartment, comprising: at least one fire-suppressant vessel containing a fire suppressant dischargeable into the cargo compartment; a discharge conduit coupled to the at least one fire-suppressant vessel; a controller coupled to the at least one fire-suppressant vessel, the controller being configured to cause discharge of a first portion of the fire suppressant into the cargo compartment over a first period of time upon activation of the fire-suppression system, the controller being configured to cause discharge of a second portion of the fire suppressant into the cargo compartment at a first rate and over a second period of time greater than the first period of time, and the controller being configured to cause discharge of a third portion of the fire suppressant into the cargo compartment at a second rate greater than the first rate and over a third period of time less than the second period of time during descent of the aircraft. 15. The system of claim 14 further comprising a valve arrangement coupled to the discharge conduit and to the controller. 16. The system of claim 14 wherein the fire suppressant is Halon. 17. The system of claim 14 wherein at least a majority of the third portion of the fire suppressant is discharged only during descent of the aircraft. 18. A fire-suppression system for use in an aircraft having a cargo compartment, comprising: a first fire-suppressant vessel assembly configured to discharge fire suppressant into the cargo compartment at a first discharge rate upon activation of the fire-suppression system; a second fire-suppressant vessel assembly configured to discharge fire suppressant into the cargo compartment at a second discharge rate after at least a portion of the fire suppressant from the first fire-suppressant vessel assembly has been discharged, the second discharge rate being less than the first discharge rate; and a third fire-suppressant vessel assembly configured to discharge fire suppressant into the cargo compartment at a third discharge rate greater than the second discharge rate, at least a majority of the fire suppressant from the third fire-suppressant vessel assembly being discharged only during descent of the aircraft. 19. The system of claim 18 wherein a portion of the fire suppressant from the second fire-suppressant vessel assembly being discharged into the compartment simultaneously with discharge of the fire suppressant from the third fire-suppressant vessel assembly into the compartment during the descent of the aircraft.
