A fire suppressant blend comprises CF3I; at least one hydrofluoro-olefin (HFO) or hydrochlorofluoro-olefin (HCFO), or both; and carbon dioxide.

Fire suppression blends of CF3I, HCFOs and CO2

An aircraft engine fire extinguishing system includes a supply housing for containing a fire extinguishing agent. Also included is a line for routing the fire extinguishing agent from the supply housing. Further included is a nozzle structure operatively coupled to the line, the nozzle structure having a non-circular opening for expelling the fire extinguishing agent.

Fire extinguishing agent nozzle structure

A fire protection system includes a fire extinguisher including a housing. The housing includes an extinguisher outlet and a burst disk. The burst disk configured to retain a volume of fire suppressant material in the housing. A firing cartridge is operably connected to the housing. The firing cartridge includes an output charge, and an ignition charge that, when detonated, causes release of the output charge to rupture the burst disk and release the volume of fire suppressant material through the extinguisher outlet. An optical fiber is configured to transmit a light signal toward the ignition charge to heat and detonate the ignition charge. A light source is operably connected to the optical fiber to transmit the light signal along the optical fiber.

A fire suppression composition comprises CFI and CO, wherein said CFI is present in an amount of from 23 mol. % to 39 mol. %, based on the total moles of CFI and COpresent in the fire suppression composition. Alternatively, the fire suppression composition comprises CFI and CO, wherein said CFI is present in an amount of from 53 mol. % to 85 mol. %, based on the total moles of CFI and COpresent in the fire suppression composition.

Fire suppression compositions

A fire suppression system in an aircraft includes a first nozzle within a region to perform discharge of a fire suppression agent in a first direction within a region. The systems also includes a second nozzle within the region to perform discharge of the fire suppression agent in a second direction within the region. The discharge in the first direction by the first nozzle and the discharge in the second direction by the second nozzle generate and maintain a vortex of the fire suppression agent that occupies the region with rotational flow.

Nozzle configurations to create a vortex of fire suppression agent

A fire suppression system includes at least one high pressure gas source containing an inert gas, at least one low pressure gas source containing an organic halide gas, a distribution network connected with the high pressure gas source and the low pressure gas source to distribute the inert gas and the organic halide gas, and a controller in communication with the distribution network. The distribution network includes flow control devices configured to control flow of the inert gas and the organic halide gas. The controller is configured to initially release the inert gas in response to a fire threat to reduce an oxygen concentration at the fire threat below a preset oxygen concentration threshold, and release the organic halide gas to increase an organic halide gas concentration at the fire threat above a preset organic halide gas concentration threshold while the oxygen concentration is below the preset oxygen concentration threshold.
