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

A fire suppression blends of CF3I and 2-BTP with mol ratios from 1:5 and 5:1 are capable of passing peak inerting and sub-inerting tests. The CF3I:2-BTP fire suppression blends can also include carbon dioxide of up to 80% of the fire suppression blend to provide additional cooling.

Fire suppression blends of CF31 and 2-BTP

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 extinguishing agent concentration measuring system including a first window, a second window positioned relative to the first window thereby defining a sensing volume between the first window and the second window, a tube configured to port a flow including the agent from an environment through the sensing volume, and a fluid motion mechanism in operable communication with the tube configured to cause the flow through the tube and through the sensing volume.
