<p>Fire protection system for use in aircraft equipped with engine and fuselage compartments. In the preferred and illustrated embodiment, the fire protection system utilizes a plurality of containers (28, 29 and 30) of extinguishant, the containers being connected to a common manifold (24). The manifold (24) connects to a number of solenoid operated, feedback connected zone valves (25), each of which is connected through a distribution line to a specified fire zone of the aircraft. A control system is included which closes certain fire zone valves, opens the one where opening is required to direct the extinguishant to that particular zone of the aircraft, and then opens an individual container. The control system additionally includes sensors (52) at selected locations around the aircraft to provide a warning to an operator who manually operates the system. The system also includes switch sensors (77, 97) which determine the operative condition of the zone valves (25). </p> |
