Abstract: A fire suppression system adapted for use in a lavatory of an aircraft. The system includes a water supply coupled to one or more fluid discharge nozzles via one or more fluid flow lines. A pressure source in communication with the fluid flow lines provides pressure to assist in supplying a pressurized flow of fluid through the flow line(s) to the nozzles(s). The fire suppression system creates a spray of water capable of suppressing fires within a waste container area or within the entire lavatory area. Heat sensitive valves enable the system to automatically detect the start of a fire. Furthermore, the system is capable of using the potable water supply of the aircraft or it can be self-contained with its own water supply reservoir. If self-contained, the system includes a pressurized fluid source to assist in supplying water to the discharge nozzle(s).

Abstract: A fire is extinguished and suppressed, by a dual stage fire extinguisher. In a first stage, a sufficient amount of an inerting agent is delivered to extinguish the fire. Once the fire is extinguished, in the second stage, a different amount of inerting agent is delivered to the fire to prevent its re-ignition. Since suppression typically requires less of the inerting agent than extinguishing, a reduction in the weight of the inerting agent is achieved with the dual stage process making the system particularly amenable to aircraft applications such as in an engine nacelle or cargo dry bay.

The nozzle atomizes the fire suppressant flowing through the nozzle so as to substantially cover the interior space of the process station with fire suppressant. The fire suppressant may be water provided by a local sprinkler system, and the nozzle is configured to atomize the fire suppressant when the fire suppressant is delivered to the nozzle under relatively low pressure.

Abstract: A mechanism for isolating energetic material feed streams from a material processing apparatus includes a deflector conduit having side panels defining a passageway from an entrance to an exit.

A conveyor may be used in conjunction with the deflector conduit to separate the conduit from a material feed hopper. A combustible conduit may be used to direct material into the deflector conduit from the end of a conveyor or from a feed hopper.

Abstract: A method for extinguishing fires in aircraft cargo spaces includes two pressure chambers separated by an annular boss which houses a restricting orifice and a check valve assembly. A lower chamber acts as a high rate discharge fire extinguisher and the upper chamber acts as a metering fire extinguisher.

With the properly sized orifice, the agent in the upper chamber will be emptied at a rate that lasts for the needed duration of the aircraft fire protection system.
