ABSTRACT:
The invention is a fire suppression system for an aircraft 10 of the type having a main cabin compartment 12, such as a passenger compartment and a plurality of closable or closed-off subcompartments. These subcompartments can be any area which is separated by fixed structure from the main cabin and therefore are normally not accessible. The fire suppression system comprises a plurality of ducts 57 coupling a plurality of subcompartments 14, 15, 22 to the main compartment. The plurality of ducts 57 have first ends of the ducts 57 terminate in nozzles 58 within the subcompartments adapted to distribute the fire suppression chemical in a specific pattern and second ends terminating in disconnect valve halves 59 accessible from the main cabin compartment. A portable unit 30 having a tank 42 filled with a fire suppression chemical under pressure is moveable within the main compartment 12. Preferably, the fire suppression chemical is Halon stored under nitrogen gas pressure. The unit 30 has a length of flexible line 54 coupled to the tank 42 and terminating in a nozzle assembly 55 having a disconnect valve half 159 mounted thereon. This disconnect valve half 159 is connectable to the disconnect valve half 59 attached to any one of the ducts 57.
