COMBINED SAND JET-WATER EXTINGUISHING FOREST FIRES FROM AIR Russian patent published in 2014 - IPC A62C2/00 

FIELD: fire-fighting equipment.

SUBSTANCE: method of combined sand jet-water extinguishing forest fires from the air due to the use of local materials and purposeful fire extinguishing only at points of contact of with burning crowns with non-burning crowns of neighbouring trees is a mobile in time of starting the whole process of fire extinguishing due to the ubiquitous proximity of consumables. According to the proposed method, the formation of sand jets occurs automatically due to the lifting height and weight of the thrown sand. The water thrown then to the remaining sources of fire with less heat liberation is used without loss by evaporation in the air directly to cool crowns, including those fallen to the ground, which ensures high efficiency of extinguishing forest fires. The extinguished area of spread of fire in the form of a band with no means of transmission of fire is a barrier for spreading fire from the ongoing passive afterburning of the isolated part of the forest.

EFFECT: improved method.
