Abstract

Methods, systems and apparatuses are disclosed for fire suppression systems in passenger vehicle cabins incorporating the use of an existing water supply and optionally existing water delivery system plumbing, or providing dedicated high-pressure water delivery plumbing to an existing water delivery system, with existing water delivery system comprising existing water delivery stations altered to comprise fixtures to facilitate the dispensing of water from the existing water delivery stations at elevated pressures, on demand.

First claim

What is claimed is:

1 . A system for extinguishing a cabin fire in a vehicle cabin, said system comprising:
at least one water supply, said at least one water supply in communication with a water supply first line; a water delivery station, said water delivery station in communication with the water supply first line, said water delivery station comprising:
a first water delivery outlet in communication with the water supply first line, said first water delivery outlet configured to deliver a first water flow at a first water flow pressure;
a second water delivery outlet in communication with the water supply first line, said second water delivery outlet configured to deliver a second water flow at a second water flow pressure; and
wherein the second water flow pressure exceeds the first water flow pressure.

2 . The system of claim 1 , wherein the first water flow pressure ranges from about 10 to about 40 psig, and wherein the second water flow pressure ranges from about 100 to about 150 psig.

3 . The system of claim 1 , further comprising a dispenser, said dispenser configured to mate with the second water delivery outlet.

4 . The system of claim 1 , wherein at least one of the second water delivery outlet and the dispenser comprise a pressure-increasing device.

5 . The system of claim 1 , wherein the system further comprises at least one pressure-increasing device, said pressure-increasing device in communication with the water supply first line.

6 . The system of claim 1 , wherein the system further comprises a plurality of water delivery stations, said plurality of water delivery stations in communication with the water supply first line.

7 . The system of claim 1 , wherein said system further comprises a water supply second line, said water supply second line in communication with the at least one water supply, said water supply second line further in communication with the second water delivery outlet.

8 . The system of claim 1 , wherein the at least one water supply is contained within an existing vehicle water tank.

9 . The system of claim 5 , wherein the pressure-increasing device comprises a venturi valve.

10 . The system of claim 5 , wherein the pressure-increasing device is in communication with an air source.

11 . The system of claim 7 , wherein said system further comprises at least one pump in communication with the water supply second line.

12 . A vehicle comprising:
a fire suppression system for delivering water, said fire suppression system comprising;
at least one water supply, said at least one water supply in communication with a water supply first line;
a water delivery station, said water delivery station in communication with the water supply first line; said water delivery station comprising:
a first water delivery outlet in communication with the water supply first line, said first water delivery outlet configured to dispense a first water flow at a first water flow pressure ranging from about 10 to about 40 psig;
a second water delivery outlet in communication with the water supply first line, said second water delivery outlet configured to deliver a second water flow from the second water delivery outlet at a second water flow pressure ranging from about 100 to about 150 psig;

a dispenser, said dispenser configured to mate with the second water delivery outlet; and
wherein said dispenser is further configured to deliver water from the at least one water supply to a target zone in a vehicle cabin.

13 . The vehicle of claim 12 , wherein the vehicle comprises at least one of: an aircraft, a rotorcraft, a terrestrial vehicle, and a waterborne vehicle.

14 . The vehicle of claim 12 , wherein the at least one water supply is an existing vehicle water supply.

15 . The vehicle of claim 12 , wherein the system comprises a pressure-increasing device.

16 . The vehicle of claim 12 , wherein the system further comprises a water supply second line, said water supply second line in communication with the at least one water supply, said water supply second line further in communication with the water delivery station, said water supply second line further in communication with the second water delivery outlet.

17 . The vehicle of claim 15 , wherein the pressure-increasing device comprises a pump.

18 . A method for installing a fire suppression system in a passenger vehicle, said method comprising:
installing a water delivery station into a vehicle, said water delivery station comprising a first water delivery outlet, and said water delivery station further comprising a second water delivery outlet; engaging the water delivery station in communication with a water supply first line; wherein said second water delivery outlet is configured to mate with a dispenser, said second water delivery outlet in communication with at least one of the water supply first line and a water supply second line; wherein the first water delivery outlet is configured to deliver a first water flow from the water delivery station at a first water flow pressure; and wherein the second water delivery outlet is configured to deliver a second water flow from the water delivery station at a second water flow pressure, said second water flow pressure is greater than the first water flow pressure.

19 . The method of claim 18 , wherein the first water flow pressure ranges from about 10 to about 40 psig, and the second water flow pressure ranges from about 100 to about 150 psig.

20 . A method for suppressing a fire in a vehicle cabin, the method comprising:
directing water from a vehicle water supply to a water delivery station, said water delivery station comprising:
a first water delivery outlet configured to deliver a first water flow from the first water delivery outlet at a first water flow pressure, said first water delivery outlet in communication with the vehicle water supply;
a second water delivery outlet configured to deliver a second water flow from the second water delivery outlet at a second water flow pressure, said second water delivery outlet in communication with the vehicle water supply;
connecting a dispenser to the second water delivery outlet, said dispenser configured to mate with the second water delivery outlet; releasing the second water flow from the dispenser; and wherein the second water flow pressure is greater than the first water flow pressure.

21 . The method of claim 20 , wherein before the step of releasing the second water flow, further comprising:
directing an amount of water from the vehicle water supply to the second water delivery outlet.

22 . The method of claim 20 , wherein the first water flow pressure ranges from about 10 to about 40 psig, and the second water flow pressure ranges from about 100 to about 150 psig.

23 . The method of claim 20 , wherein the dispenser comprises a nozzle assembly, said nozzle assembly further comprising a hose.
