Abstract:
A fire suppression composition comprises CF3I and CO2, wherein said CF3I is present in an amount of from 23 mol. % to 39 mol. %, based on the total moles of CF3I and CO2 present in the fire suppression composition. Alternatively, the fire suppression composition comprises CF3I and CO2, wherein said CF3I is present in an amount of from 53 mol. % to 85 mol. %, based on the total moles of CF3I and CO2 present in the fire suppression composition.
Abstract:
A fire suppression agent includes a fluid medium, vermiculite particles suspended in the fluid medium, and a colorant additive proximate at least a subset of the vermiculite particles. The fire suppression agent is capable of suppressing a fire comprising a combustible metal material.
Abstract:
An automated fire protection system for a freighter such as an aircraft may include a single fire retardant source for a first deck and a second deck. The system may further include a plurality of sensors for detecting fire and a plurality of nozzles for dispersing the retardant, wherein each nozzle is paired with one of the plurality of sensors. Once a fire is detected by one of the sensors, the fire protection system may eject fire retardant through only one or more nozzles paired with the sensor that detected the fire. Because retardant may be accurately dispersed close to the detected fire location through less than the plurality of nozzles, an amount of on-board retardant may be decreased, thereby decreasing weight of the fire suppression system. In an embodiment, the fire retardant may only be discharged during the descent, further decreasing the weight of the fire system.
Abstract:
A valve assembly for a pressure vessel is disclosed that includes a valve housing operatively associated with an outlet of the pressure vessel, a frangible hermetic disc sealing the outlet of the pressure vessel, and a poppet valve mounted for movement within the valve housing between a first position supporting the frangible hermetic disc within the outlet of the pressure vessel and a second position spaced apart from the frangible hermetic disc to permit the frangible disc to burst under pressure and permit the egress of pressurized material from the pressure vessel through the outlet.
Abstract:
A method is disclosed for evaluating inerting concentration of a fire suppression agent. The method includes flowing air upward into a chimney tube and flowing fuel into the flowing air in the chimney tube. A targeted concentration of the fire suppression agent is introduced into the flowing air and into the flowing fuel in the chimney tube. An ignitor is ignited to provide ignition energy to the flowing air and the flowing fuel, and the ignitor is deactivated. The targeted concentration of the fire suppression agent is at or above the inerting concentration of the fire suppression agent if combustion of the flowing fuel does not persist beyond three seconds after the ignitor is deactivated.

Abstract:
Disclosed herein is a system and method for monitoring a gaseous fire suppression blend. The system includes a sensor array having a plurality of sensors disposed in a protected space, wherein the sensor array can detect and quantify more than one component of the gaseous fire suppression blend.
Abstract:
Disclosed is a fire suppression agent composition including CF3I and an additional fire suppression agent selected from the group consisting of HFC-23, HFC-125, HFC-227ea, dodecafluoro-2-methylpentan-3-one (Novec 1230), and HCFO-1233zd(E), wherein the fire suppression agent composition passes the FAA aerosol can test.

Abstract:
A fire suppression system may comprise a shape memory actuation system. The shape memory actuation system may be configured as a retainer that retains a plug and/or a disk. The shape memory actuation system may be a shape memory plug that is configured to discharge from a vessel exhaust port. The shape memory actuation system may be deployable in response to an electrical stimulus (e.g., resistive heating causing the shape memory alloy to have a temperature exceeding a transition temperature).
