Abstract:
1. A system for manufacture and delivery of fire suppression gel, comprising in combination: an aircraft; a water container carried by said aircraft; said water container adapted to be filled with water by accessing a water reservoir; a source of gel concentrate; a blender assembly; said blender assembly including a water inlet adapted to receive water from within said container, a gel concentrate inlet coupled to said source of gel concentrate, and including a hydrated gel outlet, said blender assembly including a pump submerged within a fluid contained within said water container which pressurizes the water and hydrated gel at said outlet; a nozzle coupled to said hydrated gel outlet, said nozzle adapted to direct the pressurized hydrated gel to an area to be treated with the gel; wherein said water container is in the form of a bucket suspended by at least one line beneath the aircraft, said nozzle supported by said bucket; wherein said nozzle includes an outlet pointed mostly downward and adapted to direct pressurized hydrated gel down upon the area to be treated; wherein the nozzle outlet is oriented substantially vertically downward; wherein said blender assembly includes a combiner adapted to combine gel concentrate from said gel concentrate inlet and water from said water inlet, said pump located downstream of said combiner; wherein said pump is a dynamic pump with an impeller having a plurality of blades and adapted to rotate within a housing, such that said impeller blades both increase a pressure of the hydrated gel and promote mixing of the hydrated gel; and wherein a positive displacement pump is located between said source of gel concentrate and said combiner, said positive displacement pump adapted to control a flow rate of gel concentrate into said combiner.
