Helium gas total flood fire suppression system
First Claim
1. A fire suppression system comprising:
- at least a first reservoir for storing a fire suppressant composition for knocking down fire in an enclosed space;
piping arranged to deliver the fire suppressant composition from the at least first reservoir to the enclosed space;
a pressure sensor arranged to sense pressure of the fire suppressant compositions in the piping; and
a controllable purging device that permits air to exit the enclosed space responsive to sensed pressure in the piping of the fire suppressant composition.

Abstract
The invention provides systems and methods adaptable to all gaseous agents including Helium to suppress fire in at least one enclosed space. Suppressants are delivered by a dedicated subsystem connected to cargo compartments or to engine nacelles, or by an integrated system connected to cargo compartments and engine nacelles. For example, at least a first reservoir stores fire suppressant composition for knocking down a fire in an enclosed space. Piping delivers the composition from the at least first reservoir to the enclosed space. A pressure sensor senses pressure of the composition in the piping, and a controllable purging device permits air to exit the enclosed space responsive to sensed pressure in the piping of the composition.

12. A fire suppression system comprising:
-
first and second reservoirs for storing a fire suppressant composition;
enclosed space piping arranged to deliver a first flow of the fire suppressant composition from the first reservoir to an enclosed space at a first flaw rate, the enclosed space piping being further arranged to deliver a second flow of the fire suppressant composition from the second reservoir to the enclosed space at a second flow rate that is less than the first flow rate;
unenclosed space piping arranged to deliver the fire suppressant composition from the first and second reservoirs to an unenclosed second space;
a pressure sensor arranged to sense pressure in the enclosed space piping of the fire suppressant composition;
a controllable purging device that permits air to exit the enclosed space responsive to sensed pressure in the enclosed space piping of the fire suppressant composition; and
first and second unenclosed space squibs that actuate to permit the fire suppressant composition to flow from the first and second reservoirs, respectively, to the unenclosed space responsive to first and second signals, respectively, that are selected by a user. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for suppressing fire in an enclosed space, the method comprising:
-
delivering a first flow of a fire suppressant composition from a first reservoir through piping arranged to deliver the fire suppressant composition to an enclosed space to knock down fire in the enclosed space;
sensing pressure of the first flow of the fire suppressant composition in the piping; and
controllably permitting air to exit the enclosed space when sensed pressure in the piping of the first flow of the fire suppressant composition is greater than a first predetermined threshold pressure. - View Dependent Claims (25, 26)
