Abstract
A fire and explosion suppression system which is operative for suppressing an explosion within 100 milliseconds of the existence of a high energy ignition and within 200 milliseconds of the existence of a low energy ignition. Respective output signals from a detector of ultraviolet radiation and a detector of infrared radiation are fed to a logical AND circuit to provide a third output signal indicative of simultaneous receipt of ultraviolet and infrared radiations. Actuation apparatus responsive to the third output signal then actuates extinguishing agent distribution apparatus for discharging an extinguishing agent into the volume to be protected, such as the troop compartment and/or the engine compartment of an armored vehicle.
Claims11
A fire and explosion suppression system, comprising:
- a first detector for sensing ultraviolet radiation in a volume to be protected excluding radiation in the visible spectrum and providing an output indication I in response to receipt of such radiation;
- a second detector for sensing infrared radiation in said volume to be protected excluding radiation in the visible spectrum and providing an output indication II in response to receipt of such radiation;
- logic means for ANDing said output indications I and II and providing an output indication III of simultaneous receipt of radiation by said first and second detectors;
- extinguishing agent distribution means operative for discharging an extinguishing agent into said volume to be protected in response to an actuation indication;
- and
- actuation means operative in response to said output indication III for providing said actuation indication to said distribution means;
- said system being operative for suppressing an explosion within 100 milliseconds of the existence of a high energy ignition and within 200 milliseconds of the existence of a low energy ignition, and
- wherein said actuation means also receives an indication of the pressurized state of various elements of the extinguishing agent distribution means and a confirmation of the discharge thereof, and wherein said actuation means is operative in response to said indication and confirmation to actuate additional elements of said extinguishing agent distribution means when certain ones thereof are not properly pressurized or fail to discharge.
A fire and explosion suppression system comprising:
- detector apparatus operative to determine the existence of a fire or an incipient explosion in a volume to be protected and to provide a first output indication in response thereto;
- extinguishing agent distribution means operative for discharging an extinguishing agent into said protected volume in response to an actuation indication;
- and
- actuation means operative in response to said first output indication for providing said actuation indication to said distribution means;
- wherein said extinguishing agent distribution means comprises a container for an extinguishing agent and said container defines an opening and a discharge flow path and a high speed discharge release valve associated with said opening and wherein said high speed discharge release valve comprises:
- a rupture disc disposed across the container opening and preventing the flow of extinguishing agent therefrom;
- and
- high speed pressure generating means disposed entirely outside of said flowpath and in pressure communication with said rupture disc, such that actuation of said high speed pressure generating means provides pressure which causes rupture of said rupture disc, and permits the outflow of said extinguishing agent from said container.
