The technical result obtained by implementing the device is to reduce its cost while expanding the application area, increasing efficiency by increasing the kinetic energy of the particles of the extinguishing agent. 8 C.p. f-crystals, 1 Il.The invention relates to the field of active impact on natural and artificial objects, preferably delivered to the specified objects are planes and helicopters, and can be used to extinguish fires, ice, avalanche situations, as well as for the complete destruction of dilapidated buildings.It uses the term “conical surface”, which in the context of the proposed description meets the definition set forth in the Great encyclopedic dictionary “Polytechnic” (M.: Large Rossick orpus with a hole for the release of extinguishing agent, the charge generating fire extinguishing agent, and the node initiating the charge.In case of fire, the site of initiation (cutter) undermines the specified charge, and the resulting undermining of fire extinguishing agent (aerosol) through the indicated hole comes out of the casing in the zone of fire.A disadvantage of the known device should recognize the possibility of additional fire due to actuation of the site of initiation.Know the use of bombs for destruction of ice jams on the rivers and also fight with avalanche danger.However, the use of bombs for these purposes leads to disruption of the ecology of the reservoir due to the explosion of the explosive, and there is the possibility of destruction of biological objects (people and animals) fragments of the body of the bomb and the blast.The closest analogue of the proposed device can recognize the device for extinguishing fires (RU, patent 2073541, 1997). The known device comprises a flexible envelope filled with extinguishing agent contained in the vessel, the Capturer of the tank, above the zone of fire and the means of destruction of the shell and the tank is made of mesh elastically in its center and is shipped in a fire extinguishing agent.In the baseline implementation, the device comprises a flexible membrane in the form of a bag made in particular of polyethylene. The shell is filled with fire-extinguishing substance, in particular a liquid, and placed in a container made of metal elastic mesh. Tool failure envelope is an explosive charge mounted within the casing and immersed in the fire extinguishing agent. The means of retention is made in the form of a tube, to a shaped surface through which the elastic clip is pressed net capacity and elastic shell. The means of retention has a filler neck with an opening covered in the operating mode by a threaded plug, which is made with a hole for the cord to charge. Reticulated shell has openings representing evenly placed around the perimeter of the cells in which subside sections of elastic shells.The known device operates as follows. The cord signal to undermine an explosive charge. The explosion dramatically increases the pressure in the elastic membrane, through which the fire extinguishing agent is uniformly distributed on the entire area of the walls of the specified shell, parts of which are forced through the cell when ASEE tool freely poured on the fire.A disadvantage of the known tools should recognize its low efficiency, due to the kinetic energy of the particles extinguishing media flowing to the fire.The technical problem to be solved by the proposed device is to improve its efficiency and simultaneous expansion of its capabilities.The technical result obtained by the implementation of the proposed device is to reduce its cost while expanding the scope to increase efficiency by increasing the kinetic energy of the particles missile substances.To achieve the technical result of the proposed use of the bomb, containing a shell filled with liquid or powder, in particular fire extinguisher, and an explosive charge mounted within the shell, and the shell has a side surface, extending to the bottom (preferably a conical shape and, in particular, pyramidal) and a convex bottom, and the bottom surface includes at least one depression, the depth of which does not exceed the distance from the bottom surface to the section plane passing through the perimeter of the connection of the bottom and side surface (canina part of the conical side surface and a convex bottom with depression - leads to a sharp increase in kinetic energy missile substances. In the case of application of the liquid extinguishing agent (predominantly water-based) comes knocking over an open fire with the penetration of the liquid in the previously burning material. When using powdered extinguishing agent is also knocking down open fire with dense adhesion of the powder to the surface before burning material. When you use these bombs to prevent fire, liquid or powder not just cover the surface of combustible material, but also penetrate into it or tightly isolate it from fire. In the case of applying the proposed bombs to clear avalanches or debris flows kinetic energy of the water causes the programmed avalanche or mudslide. If necessary, the destruction of the ice bridges kinetic energy of falling water causes bulkhead cracks without causing damage to the environment. The final destruction of damaged as a result of natural or man-made disasters buildings is also due to the high kinetic energy missile substances.Depending on the purpose bomb may have different sizes, which is the Eney four of these depressions. Also it has been experimentally observed that the presence of regularity in the arrangement of the depressions on the bottom allows you to put some more kinetic energy missile substances. This preferably with a conical shape of the side surface of the shell with a circumference at the base to have the distance between the centers of the depressions 40 to 80% of the radius of a circle connecting bottoms and tapered (side) parts, but with the pyramidal shape of the side surface of the shell, the distance between the centers of the depressions is preferably from 20 to 40% of the larger base of the perimeter of a rectangle connecting the bottom and side. The depth of the depressions is usually from 20 to 100% of the distance from the bottom surface to the plane of the connection of the bottom and side surfaces. The shell may be made of a polymeric material (polyethylene, PVC, rubber and so on) or woven material, preferably covered with a permeable material. The main requirements to the shell is the ability to create a relief of the seabed and the ease of the failure envelope. These depressions can be formed in the manufacture of the shell, and can also be performed by attaching point seabed to a solid support placed inside Obolo is her side of the shell at the junction of the bottom and side shell, or cord, which is fixed to the explosive charge. To enhance directional bombs lateral part of the shell made of a more durable material than the material of the lower part; in the simplest case, for the manufacture of the side use the same material from which made the bottom, but with a greater thickness.The drawing shows a view of the proposed bombs in the cut, with the following notation is used: 1 - shell 2 - liquid or powder, in particular the fire-extinguishing substance, 3 - explosive charge, 4 - bearing, 5 - tool low spots, 6 - basin.
