Abstract

A fire fighting system for fighting forest and brush fires under dry, hot and windy conditions which includes a jet engine for generating a high speed air stream, a water source for supplying water to a cooling system which lowers the water temperature to between forty and fifty degrees fahrenheit, a nozzle for injecting cold water into the air steam and a filter which provides very fine particles of cold water within the stream. The stream of cold water is directed to a forest or brush fire dropping the temperature of the fire which eventually extinguishes the fire.

Claims (12)

1. A fire fighting system for controlling and extinguishing a forest and brush fire under dry and windy conditions, comprising:

(a) a plurality of jet engines positioned in proximity to said forest ad brush fire, each of said plurality of jet engines generating a high velocity air stream;

(b) a first pump for withdrawing jet fuel from a fuel source and providing said jet fuel to each of said plurality of jet engines;

(c) a cooling system for cooling water withdrawn from a reservoir to a temperature of forty to fifty degrees fahrenheit;

(d) a plurality of nozzles, at least one of said plurality of nozzles being positioned in a path for the air stream generated by each of said jet engines;

(e) a second pump connected to said cooling system and each of said plurality of nozzles to transfer pressurized cold water from said cooling system to each of said plurality of nozzles;

(f) said at least one nozzle associated with each air stream injecting said pressurized cold water into the path of said air stream forming an air water mixture within said air stream; and

(g) a plurality of filters, one of said filters being positioned in the path of said air stream generated by each of said jet engines, each of said filters generating fine particles of cold water within said air water mixture passing through said filter, wherein said fine particles of cold water within each of said air streams are projected into the atmosphere at the edge of said forest and brush fire dropping the temperature to forty to fifty degrees fahrenheit at the edge of said forest and brush fire which creates a barrier against said forest and brush fire containing and then extinguishing said forest and brush fire.

2. The fire fighting system of claim 1 wherein the high velocity of said air streams generated by each of said plurality of jet engines is between 100 mph and 400 mph.

3. The fire fighting system of claim 1 wherein a particle size for said fine particles of cold water is from about one micron to about forty microns.

4. The fire fighting system of claim 1 wherein each of said filters comprises a screen mesh.

5. The fire fighting system of claim 1 wherein said cooling system comprises a refrigeration unit.
