WATER SPRAY SYSTEMS

摘要

2068720 9107208 PCTABS00005 A water spray system (figure 1) for an aircraft has a plurality of spray outlet nozzles (6', 6'', 6''') which are distributed throughout the passenger cabin of the aircraft and are coupled to a water storage vessel (1). A pyrotechnic gas source (5) is used to pressurize the water stored in vessel (1). The system may comprise a plurality of sub-systems each being associated with a respective section of the aircraft cabin and being operable independently of the others. The pyrotechnic gas source (5) can be actuated by a control signal (IO) produced by a control unit (8) in response to different input signals, and the or each storage vessel is fitted with an exhaust valve (11) to vent the stored water if the system is actuated inadvertently. The spray outlet nozzles may operate in different modes and may be directed to increase the residence time of water droplets in an upper part U of the cabin. The system may be coupled to an external supply system by means of a remotely launched projectile.
