DEVICE FOR EXTINGUISHING FOREST FIRES Russian patent published in 2018 - IPC A62C3/02 

FIELD: means of ensuring safety.

SUBSTANCE: invention relates to fire fighting equipment, in particular to devices for extinguishing forest fires with water (extinguishing liquid) from air, mounted on amphibious aircraft. Essence of claimed invention lies in that the amphibian aircraft is equipped with a device consisting of two vertically arranged cases. Device is mounted inside the boat hull of seaplane. Containers are placed in the cases, said containers being filled with a fire extinguishing liquid (water). Containers are filled with water from natural reservoirs using two water intake devices built in the bottom of the seaplane, said containers also serve as a conduit for raising seawater. In the planning mode of the seaplane, water passes the water intake device/conduit and, under the pressure of its high-speed head, enters the tanks. After filling the containers with water, the water is mixed with solid chemical extinguishing agents in flight, and the containers are sealed. When the seaplane approaches the fire, both containers are exactly released onto the fire source. Entire volume is 100 % delivered to the burning surface.

EFFECT: technical result of the invention is high efficiency of extinguishing forest fires using amphibian aircraft due to precise release of the extinguishing liquid (water) packed in sealed biodegradable containers.
