    摘要： Afire suppression system (20) for an aircraft cargo compartment (12) comprises a source (22) of fire suppression agent and a supply line (42) for conducting the fire suppression agent to the compartment (12). The supply line (42) has one or more flow control valves (48) arranged between the source (22) and the cargo compartment (12). A controller (38) controls the flow control valve (36, 48) to control the supply of fire suppression agent to the cargo compartment (12) from the source (22). A first pressure sensor (52) senses the pressure within the cargo compartment (12) and a second pressure sensor (54) senses the pressure within an area (14, 16) external to the cargo compartment (12). The first and second pressure sensors (52, 54) are in communication with the controller (38) which is configured to control the flow control valve (48) to reduce the flow of fire suppression agent to the cargo compartment (12) when at least one of a difference in the pressures sensed by the first and second pressure sensors (40, 42)), a ratio of the pressures sensed by the first and second pressure sensors (52, 54) or a rate of change in a pressure increase measured by the first pressure sensor (52) exceeds a respective predetermined value.

    摘要： Exemplary embodiments pertain to the art of first suppressants and, in particular, to maintaining a desired and constant blend of multiple fire suppressants during discharge. The present disclosure provides fire extinguisher assemblies utilizing a constant blend ratio of fire suppressant agents during discharge. More particularly, the present disclosure provides fire extinguisher assemblies utilizing a constant blend ratio of a first fire suppressant agent (14) (e.g., a low-boiling, high-volatility agent) and a second fire suppressant agent (16) (e.g., a higher-boiling, lower-volatility agent) during discharge. The embodiments and fire extinguisher assemblies described herein can help keep the pressure constant during discharge of the fire extinguisher assemblies.

    摘要： A fire suppression system (12) includes at least one first gas source (24) containing an inert gas, at least one second gas source (26) containing an organic halide gas, a distribution network (28) connected with the first gas source (24) and the second gas source (26) to distribute the inert gas and the organic halide gas, and a controller (38). The distribution network (28) includes a common manifold (30), input lines (32) connecting the first gas source (24) and the second gas source (26) with the common manifold (30), output lines (34) leading from the common manifold (30), and flow control devices (36). The controller is in communication with the distribution network (28) and configured to distribute the inert gas responsive to a fire threat signal and determine whether to distribute the organic halide gas based upon a location of a fire threat.

    摘要： A fire suppression method and system in an aircraft involves a pressurized first-stage agent, and a pressurized second-stage agent. The first-stage agent or the second-stage agent includes trifluoromethyl iodide (CF 3 I). A plurality of outlets discharge the first-stage agent during a first duration and the second-stage agent during a second duration. An opening of each of the plurality of outlets is located in a lower quarter of a height of a cargo compartment.
