Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the technology of fighting forest fires by dumping water from aircraft to fire sources. The method of fighting forest fires using aircraft, comprising loading of water on board of the aircraft and the subsequent pouring it into plastic bags, dumping them to fire sources, is characterised in the fact that the dumping of plastic bags from the aircraft to fire sources is carried out along the radial guides that are located in places of dumping.

EFFECT: improved method.

Description

The invention relates to a technology for extinguishing forest fires by discharging water from air transport to fires.

A known method of extinguishing forest fires using aircraft (see RU No. 2250122 C1 of 04/20/205), including loading water on board aircraft and its subsequent discharge in plastic bags to the fires (prototype).

The known method has technological capabilities, which consists in the fact that the discharged water in plastic bags at a high speed falls on the outer surface of the forest and the plastic bag breaks from impact on the ground and water from impact on the ground scatters in the vicinity of the fall and excludes oxygen through evaporation for the further course of the chemical combustion reaction.

A disadvantage of the known technological solution is the limited zone of water expansion in relation to the flight path of aircraft, which minimizes the process of localization of a forest fire.

The technological result of the proposed invention in accordance with graphoanalytic expression of the form

is an increase in the expansion zone of discarded “H ₂ O Packets” with respect to the flight path of aircraft

The specified technological result is achieved in the following way.

A method of extinguishing forest fires using aircraft, including loading water on board the aircraft and then pouring it into plastic bags, discharge them into the fires, while dumping plastic bags from aircraft into the fires carry out radial guides that are located in places reset.

The proposed method of extinguishing forest fires using aircraft is as follows.

As a result of dumping from a high altitude to the source of ignition of plastic bags that have significant weight, they overcome the outside of the source of fire with a fairly high speed and fall to the surface of the earth. As a result of the impact of the plastic bag on the surface of the earth, it is destroyed and the water that was in its volume, in the form of "drops" under the influence of the "kinetic energy" of the fall, spreads at a high speed in a fairly large area. And these water droplets intensively evaporate, which leads to the displacement of oxygen from the "epicenter" of ignition to its outer surface. And if we take into account that the process of water evaporation is not “instantaneous”, but has a specific technological cycle, then the possibility of resuming re-ignition is limited by the technological process of oxygen entering the ignition zone, which depends on minimizing water vapor in it. And if you perform the reset procedure of "Packets with H ₂ O" in accordance with the graphoanalytic expression of the form

then the “Radial guides” allow you to make the deviation of the dropped “Packets with H ₂ O” to the “Deviation angle” from the “Flight path” of the aircraft, and thereby increase the area of simultaneous extinguishing of fires during one flight of aircraft.

The use of the invention allows to minimize the extinguishing of forest fires with minimized water costs.
