DESCRIPTION:
BRIEF SUMMARY
The present invention relates to fire protection systems, and more particularly to a fire protection system for an aircraft.
There is disclosed in my earlier Australian patent No. 539,846 a fire protection system for two engines of an aircraft, comprising two fire extinguishers each having a single outlet head which leads, via a two position rotary distributor valve common to both extinguishers, to a respective one of the engines. In a first position of the valve, the extinguishant from the first extinguisher is directed to one of the engines and the extinguishant from the second extinguisher is directed to the second of the engines. If in the event of a fire in one of the engines, the extinguisher normally associated with that engine exhausts before the fire is extinguished, the rotary distributor valve can be switched to a second position in which extinguishant from the other extinguisher is directed to the fire. This previously proposed system is simpler and uses fewer components than conventional fire protection systems, while meeting CAA and FAA requirements. My previously proposed system thus permits important weight savings to be achieved.
The present invention concerns improvements to the extinguisher head and to the fluid distributor valve.
According to one aspect of the present invention there is provided a fluid distributor valve comprising a valve body having a plurality of inlet ports and a plurality of outlet ports, a valve member movable in the valve body between a first position in which the valve member provides discrete fluid communication between each respective inlet port and a respective one of the outlet ports and a second position in which the valve member provides discrete fluid communication between each respective inlet port and a different outlet port to that with which communication is provided in the first position, locking means for releasably locking the valve member in its first position, and explosive actuation means operative to effect release of said locking means and to displace the valve member from said first to said second position in which said valve member is locked against movement.
Preferably, the valve member is a rotary valve member with the first and second positions of the valve member being different angular positions, and the explosive actuation means comprises an explosively-driven pin which co-operates with the valve member when in its second angular position in order to lock the valve member in its second angular position.
According to another aspect of the invention, there is provided a fire extinguishing system for protecting two engines of an aircraft, said system comprising two fire extinguishers, each extinguisher having a single outlet head, explosive means associated with each said head for permitting discharge of extinguishant from the head, a distributor valve as above defined having only two inlet ports and only two outlet ports and a valve member rotatable between two positions, in a first of said positions the valve member connecting the first of said inlet ports with the first of said outlet ports and the second of said inlet ports with the second of said outlet ports, and in the second of said positions the valve member connecting the first of said inlet ports with the second of said outlet ports and the second of said inlet ports with the first of said outlet ports, a first conduit extending between the head of the first of said extinguishers and the first inlet port, a second conduit extending between the head of the second of said extinguishers and the second inlet port and a third conduit extending between the first outlet port and the first of said engines, a fourth conduit extending between the second outlet port and the second of said engines.
According to yet another aspect of the invention, there is provided an explosively actuated fire extinguisher outlet head comprising a housing having a passage adapted to communicate with extinguishant under pressure, said passage comprising a first passage portion and a second passage portion d
