Abstract: 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 (CF3I). 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.

Abstract: 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.

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: A fire extinguishing composition includes a propellant, a dry chemical fire extinguishing agent and an anti-decomposition agent.

Abstract: A system includes a turbo pump to convert compressed gas into power, a storage tank to store the compressed gas, and a fire suppression control valve having a closed position in which the compressed gas is prevented from flowing to the cargo compartment and an open position in which the compressed gas is ported to the cargo compartment to suppress a fire. The system also includes a pump control valve having a closed position in which the compressed gas is prevented from flowing to the turbo pump and an open position in which the compressed gas is ported to the turbo pump to cause the turbo pump to convert the compressed gas into the power. The system also includes an OBIGGS to convert bleed air from a gas turbine engine into an inert gas to provide low rate discharge (LRD) fire suppression to the cargo compartment.
