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 flow control device is including a tubular body including a tubular wall with an inner surface, an outer surface, and one or more openings extending from the outer surface to the inner surface through the tubular wall; a faired body encircling the tubular body, the faired body including a radially inner surface and a radially outer surface; and a flow shield encircling the faired body, the flow shield including a radially inward surface and a radially outward surface, the radially inward surface being in a facing spaced relationship with the radially outer surface of the faired body defining a passageway therebetween, wherein the passageway is fluidly connected to the one or more openings.

Omni-directional particulate extraction inlet

A nozzle of a fire suppression system includes a housing. Two or more orifices in the housing emit a fire suppression agent. Each of the two or more orifices emits the fire suppression agent in a rotational vortex.

A particle concentration measurement system includes a first window and a second window separated by a sensing volume. The system also includes one or more supports to provide structural support for the first window at a first end and for the second window at a second end, opposite the first end, of each of the one or more supports. The sensing volume is defined by the one or more supports and the first window and the second window is open to an environment of the particle concentration measurement system adjacent to the one or more supports such that particle-laden gas from the environment that includes particles mixed with other materials enters the sensing volume. A first compressed gas orifice directs compressed gas onto the first window to clean the first window and a second compressed gas orifice directs the compressed gas onto the second window to clean the second window.

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 flow control device includes a flow shield defining a volume and a plurality of shield openings of the flow shield arranged such that gas entering the volume must pass through at least one of the plurality of shield openings. The flow control device also includes a flow restrictor to define an opening for the gas exiting the volume.

Flow control device for particle concentration measurement sensor

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 particle concentration measurement system includes a first window and a second window in a housing. The first window and the second window respectively define a first end and a second end of an interaction region between the first window and the second window. The system also includes a particle-laden gas inlet through a wall of the housing between the first window and the second window. The particle-laden gas inlet introduces particle-laden gas from an environment that includes particles mixed with other materials into the interaction region. A first set of clean gas inlets through the wall of the housing are at different radial positions of the housing and at a first axial location of the housing, and a second set of clean gas inlets through the wall of the housing are at different radial positions of the housing and at a second axial location of the housing.

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 flow control insert includes a main body that is shaped as a cylinder, is hollow, and includes an opening at a first end and at a second end, opposite the first end, along an axial length of the cylinder. An outer surface of the main body includes threading to screw into complementary threading on an inner surface of a pipe configured to flow an agent. The flow control insert also includes a diverter within the main body or extending from the first end of the main body. The diverter controls a mass split of the agent or flow energy of the agent flowing in the pipe.

Flow control insert for an agent distribution system

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.
