Assignee:

The Boeing Company - Seattle WA

International Classification:

A62C 3512

US Classification:

169 62

Abstract:

In an aircraft (8) having a passenger carrying compartment or passenger cabin (34), an environmental control system, and a cargo fire extinguishment system (36), another fire extinguishment duct is utilized for connecting the fire extinguishment system (36) to the environmental control system. Fire extinguishment is communicated into the environmental control system by the duct and onward into the passenger cabin (34) when a fire is present therein.

The Boeing Company - Seattle WA

International Classification:

A62C 3512

US Classification:

169 62

Abstract:

A fire suppression method and system for use in an enclosed area employs the denser-than-air characteristic of certain fire retardant materials. An enclosed area has an upper region, a middle region, and a lower region. The method and system disperses a fire retardant material in a layer across the top of the upper region while maintaining concentration of the material in the layer which is sufficient to suppress any fire with which the layer comes into contact The method permits the layer to descend from the upper region, through the middle and lower regions, until it settles near the floor of the area. The descent of the layer scours the entire area to locate and suppress fire. Dispersal means includes a conduit extending horizontally in the upper region having a horizontally extending opening for dispersing the fire retardant material into the layer. Dispersal means also includes a conduit with a plurality of downwardly directed nozzles, each nozzle having a baffle means. Velocities of dispersion of the fire retardant material are low enough to prevent the formation of air currents that would impede the descent of the layer, and high enough to permit adequate spreading of the fire retardant material in order to form the layer.

Abstract:

A fire extinguishing system including a first rapid discharging Halon bottle (I) and a second metered discharging Halon bottle (II), and the method for providing a violent boil-off when the Halon is discharged from liquid nozzles (60) connected to the second bottle (II) to provide for a thorough and rapid mix of the gas within the compartment.
