The invention relates to fire fighting, and more specifically concerns a device for localization and/or suppression of fires, and can be used for effective control of large-scale and powerful fires, including forest and forest-steppe, and fires that occur in remote places as geographically (steep mountains, impassable taiga, jungle), and because of the proximity of hazards (explosions, high temperature).

A device for extinguishing forest fires from the air (U.S. patent No. 4344489, IPC And 62 With 3/02), consisting of a shell filled with an inert gas under pressure which is released on fire and automatically distribute the gas. Upon impact of the device on the ground many existing body holes simultaneously open, allowing the extinguishing agent to apply on the prescribed area.

The disadvantages of this device are as follows:

- design complexity, and consequently, the high cost of the device;

low reliability actions (the set of elements that must simultaneously involve);

- the lack of the Oia and as a consequence, the failure of it in action;

- inability to apply as a means of delivery of military aircraft and helicopters, as the design of the device does not have a suspension system that allows you to hang the device on the beam holder of the media.

Known fire bomb under the patent of Russian Federation №2068286, 6 And 62 With 39/00.

Bomb includes a housing with a stabilizer, filled with fire-extinguishing composition, and the bomb is equipped with a blade screw connected with the worm screw, and the body is made of two halves, the disclosure of which is worm screw.

The disadvantages of this device are as follows:

- low efficiency, since the disclosure of the hull fire extinguishing composition is poured in a small area;

- the design complexity;

- the lack of a suspension system that does not allow its use with military helicopters and planes.

Known fire extinguishing device according to the author's certificate No. 1712245, 64 D 1/16. Fire extinguishing device consists of a thin-walled metal tank filled with fire-extinguishing composition, stabilizer, suspension system, allowing the use of army aviation (planes, helicopters) as is.

The disadvantages of this device are as follows:

- slivers in the field of material capacity at the time of triggering of the charge excludes the possibility of using the device for extinguishing fire in an urban environment and significantly reduces the security of its application for suppression of forest and steppe fires;

- low efficiency due to the uneven distribution of the fire extinguishing composition in the area.

Closest to the proposed aircraft fire extinguishing means is paropamisadae device (patent RF №2111032, 6 And 62 With 3/02 - prototype) containing capacity of pressed cardboard, dispersing the charge block stabilizer and a fuse device in the form of a height sensor and/or contact sensor with the initiators of the explosion.

In the case of using the helicopter as a means of delivery device according to patent 2111032 should be placed in a special container suspended under the helicopter, and fixed by the lock releasing device according to the reset signal.

The disadvantages of the prototype are as follows:

- impossibility of using airplanes and helicopters of army aviation, equipped beamed holders for hanging goods, as the p>

- reduced flight performance of aircraft and vehicles, equipped paropamisadae devices (largely this effect in the case of the use of aircraft as a means of delivery), because of the increased drag coefficient device (the head of the vessel is made in the form of a truncated cone low height);

- low coefficient of payload due to the necessity of placing the device in a special container and manufacturing capacity from a material with low strength properties;

- high complexity manufacturing capacity due to the need for the development and manufacturing of special tooling, as well as the need to apply a waterproof coating.

In addition, the materials of the application prototype, no information about the design and material of the stabilizer, which can have a significant impact on the ratio of the payload device, and therefore, the efficiency of the device in the zone of fire.

The task of the invention is to increase the effectiveness of aviation extinguishing media while increasing its efficiency actions in the fire zone and napolnitelei vehicle aircraft fire suppression military (army) aviation while increasing the contact surface of the fire extinguishing composition of the burning material, the ratio increased payload and reducing the complexity of its manufacture.

The technical result is achieved by the fact that the aviation fire extinguishing means includes a fuse device, made of thermoplastic polymer material, stabilizer and capacity in the cavity where the fire extinguishing composition and dispersing the charge harness is placed on the outer surface of the container symmetrically transverse plane passing through the center of mass of the aircraft fire extinguishing means, and is made in the form of two hoops, spaced apart and rigidly connected by a strap from his ears.

The use of army aviation as a means of delivery without any modification is possible if the suspension extinguishing media on a regular beam holders of cargo, which is equipped with planes and helicopters of army aviation.

Supply of aviation fire extinguishers suspension system, placed on the outer surface of the container symmetrically transverse plane passing through the center of mass of fire extinguishing means in the form of two hoops, spaced apart and rigidly connected by a strap with eyelets, allows you to provide a suspension on his Stateline dropping into the zone of fire.

Implementation capacity and the stabilizer of a thermoplastic polymer material, for example polyethylene, allows comparison with the prototype to increase the ratio of useful load of aircraft fire extinguishing means, since the proposed material stronger than pressed cardboard (and therefore, allows for the same size to reduce the thickness of the vessel wall and increase the amount of fire extinguishing composition), does not absorb moisture (eliminates the need of applying a water-resistant coating), does not require the development and manufacture of special tooling for the manufacture of tanks and stabilizer.

In addition, the proposed material has an elongation at break of 700%, which significantly reduces the size of the droplets fire extinguishing composition in the dispersion, since the destruction of housing capacity occurs after a significant increase of its initial volume, which ultimately leads to an increase in the surface interaction of the composition with the burning material, and consequently, to increase the efficiency of the extinguishing media.

Aviation extinguishing agent can be equipped with a fairing, made in the form of classified along the longitudinal axis of dillenia aviation fire extinguishers, therefore, to improve the flight characteristics of the vehicle, equipped with the standard beam holders cargo.

In the cavity of the sleeve can be placed gear explosive charge, which increases the detonation impulse transmitted from a fuse device for dispersing the charge, thereby increasing the reliability of the aircraft fire.

In Fig.1 shows the aircraft extinguishing agent.

In Fig.2 shows the aircraft extinguishing agent with the fairing.

In Fig.3 shows the fairing and its relation with the bottom of the container.

Aviation fire extinguishing means includes a tank 1 containing fire-extinguishing composition 2 and dispersing charge 3, a fuse device 4, the stabilizer 5, the suspension system in the form of two hoops 6, the pads 7 and Ushkov 8.

Aviation extinguishing agent may be provided with a fairing in the form of a disk 9 and the sleeve 10, which is connected to the bottom 11 of the tank. In the cavity of the sleeve hosted its final explosive charge 12.

Aviation extinguishing agent when you reset it with the carriers, are equipped with the standard beam holders of goods, works as follows.

At the command of the pilot podaetsya disengage and extinguishing agent under the action of gravity is separated from the carrier, when this pulse of electric current through the rail transport of momentum media is fed to the electric igniter fuse device 4, which after a time long cock ready for action.

At a meeting of the aviation fire extinguishers with soil or foliage of trees) triggered a fuse device 4, a detonation impulse which directly or through transfer of the explosive charge 12 will involve dispersing the charge 3.

The resulting actuation of dispersive charge detonation wave and the products of the explosion increases the pressure in the vessel volume 1 in hundreds of thousands of times, which leads to the destruction of the body of the container 1, the hoops 6 suspension system and throwing fire extinguishing composition 2. During the movement of the fire extinguishing composition 2 is broken up into droplets of a size of several tens of microns, which increases the surface interaction of the composition with the burning material. The extension products of the explosion causes the formation of air shock wave, which travels at supersonic speed ahead the clouds dispersed composition. The mechanism of quenching is simultaneously exposed to the fire of the air waves, velocity head and extinguishing the burning and insulates the material, stopping the pyrolysis and heating of the environment.

Aviation tool can be used with media that are not equipped beamed holders cargo (civil aviation), thus instead of a suspension system is used, for example, hanging the container used in the prototype.

For their technical and economic parameters of the proposed aviation extinguishing agent allows you to:

- as a means of “first strike” to suppress the intense burning zones dozens of times to increase the effectiveness of traditional drainage systems;

to attract a military aircraft to solving problems and putting out fires without any costs of modification of aircraft and helicopter parks;

to solve the problem without bringing in the fire zone for more number of people and machinery due to the practical elimination of dangerous shrapnel and high explosive actions;

- use it to extinguish fires in zones of radioactive contamination.
