摘要： A fire suppression system comprises an electric solid propellant (ESP) (10) configured as a solid mass, and a circuit (12) configured to flow current through the ESP (10). The ESP (10) includes a polymer material, an oxidizer, and at least one chemical additive. The circuit (12) includes a power source (22), an anode (18) in physical communication with the ESP (10), and a cathode (20) in physical communication with the ESP (10) and oppositely disposed from the anode (18).

摘要： A system (104) includes a turbo pump (206) to convert compressed gas into power, a storage tank (200, 202, 204) to store the compressed gas, and a fire suppression control valve (208) having a closed position in which the compressed gas is prevented from flowing to the cargo compartment (102) and an open position in which the compressed gas is ported to the cargo compartment (102) to suppress a fire. The system (104) also includes a pump control valve (212) having a closed position in which the compressed gas is prevented from flowing to the turbo pump (206) and an open position in which the compressed gas is ported to the turbo pump (206) to cause the turbo pump (206) to convert the compressed gas into the power. The system also includes an OBIGGS (118) to convert bleed air from a gas turbine engine (114) into an inert gas to provide low rate discharge (LRD) fire suppression to the cargo compartment (102).

摘要： A fire extinguishing agent concentration measuring system (10) includes a first window (38), a second window (42) positioned relative to the first window, thereby defining a sensing volume (18) between the first window and the second window, a tube (54) configured to port a flow of a fluid (20) including the agent (22) from an environment (62) through the sensing volume, a fluid motion mechanism (66), such as a pump or a vacuum source, in operable communication with the tube and configured to cause laminar or turbulent flow of the fluid through the tube and through the sensing volume, a light source (26) for transmitting light through the first window, the sensing volume and the second window, and a sensor (50) for detecting the light after passing through the first and second windows and the sensing volume. The sensor may be calibrated to correlate the detected light to a concentration of the fire extinguishing agent, which may be solid particulates scattering the light.

摘要： A valve assembly (10) for a pressure vessel (16) is disclosed that includes a valve housing (12) operatively associated with an outlet (14) of the pressure vessel, a frangible hermetic disc (18) sealing the outlet of the pressure vessel, and a poppet valve (20) 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.

摘要： 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.
