Description

Technical field

The thermobaric warhead is used in the defense industry and, in particular, in the structures of the warheads of bulk detonating ammunition.

BACKGROUND OF THE INVENTION

An ampoule grenade launcher is known [1]. The warhead is composed of a chamber formed by an outer and an inner housing and is filled with a multicomponent thermobaric mixture with different density of components. The bursting charge is located along the axis of the inner housing on which the explosive device is located. In the warfare described above, there is a stratification of the components of the thermobaric mixture of heavy and light fractions in the storage of ammunition, as well as temperature expansion and shrinkage of the mixture. Optimization of the relative positioning of the components of the mixture is achieved by firing and during the flight itself. The temperature expansion of the mixture is compensated by the empty volume left in the ampoule. Non-destruction of the thin-walled ampoule by the inertial forces of the thermobaric mixture is achieved by the compensating pressure generated by the gases of the throwing charge. Flight stability is ensured by the rotational motion of the grenade.

The technical nature of the utility model

The objectives of the utility model are to avoid the separation of the components of the thermobaric mixture of heavy and light ammunition during storage of ammunition, to avoid empty volume in the chamber as a means of temperature compensation of the mixture during storage, to create a thin-walled thermobaric warhead with permanent center of gravity located along the axis of the thermobaric warhead and increased thermobaric action.

The problem was solved by creating a thermobaric warhead consisting of an og chamber formed by an outer and inner housing. The chamber is filled with an explosive, using a multi-component stabilized, non-stratifying thermobaric mixture as the explosive. The components of the thermobaric mixture are of different densities and the separation of heavy and light fractions is prevented by the introduction of an additional stabilizing component. The homogeneous, thermally stable, non-stratifying mixture possesses increased thermobaric action, stability of results, does not allow the center of gravity of the thermobaric warhead to be displaced and promotes stable flight of the shot.

In the inner housing, located along the axis of the thermobaric warhead, is placed a burst-burst charge that serves to disperse and initiate the thermobaric mixture. For maximum thermobaric effect, it is necessary that the amount by weight of the flammable burst charge be from 5 to 20% of the mass of the thermobaric mixture, the exact percentage ratio depending on the caliber and the volume of the chamber, depending on the caliber and the type of ammunition. The initiation of the burst charge is carried out by an explosive device. The temperature expansion (shrinkage) compensation device is located in the rear, front or rear and front of the chamber. In dynamic conditions, the temperature expansion (shrinkage) compensating device acts as a damping device, unloading the walls of the outer and inner housings.

A stabilized, non-stratifying thermobaric mixture is used 1255. The components of the thermobaric mixture are of different densities, preventing the separation of heavy and light fractions by introducing an additional stabilizing component. In the inner housing 2, located along the axis of the thermobaric warhead, is placed the bursting charge 4, which serves to disperse and initiate the thermobaric mixture 3. The amount of bursting charge 4 is from 5 to 20% of the amount of thermobaric mixture. The initiation of the burst charge 4 is carried out by the blasting device 5. The compensating device for temperature expansion (contraction) 6 is located at the rear of the chamber - FIG. 1.

The chamber is filled with explosive material, using a stabilized non-stratifying thermobaric mixture 3. The components of the thermobaric mixture have different densities, preventing the separation of heavy and light fractions by introducing an additional stabilizing component. In the inner housing 2, located along the axis of the thermobaric warhead, is placed a burst burst charge 4, which serves to disperse and initiate the thermobaric mixture 3. The amount of burst burst charge 4 is from 5 to 20% of the amount of thermobaric mixture. The initiation of the burst charge 4 is carried out by the blasting device 5.

Using the utility model

The thermobaric warhead (Figs. 1, 2, 3) operates in the temperature range from 223 to 323 K (minus 50 ° C to plus 50 ° C). At 223 K, the thermobaric mixture 3 shrinks, and the temperature expansion (shrinkage) compensator 6 expands, preventing the appearance of an air cavity. At 323 K, the thermobaric mixture 3 expands, and the compensating device of the temperature extensions 6 shrinks, preventing the formation of overpressure in the chamber, loading the two thin-walled housings 1 and 2.

When firing the thermobaric warhead (Figs. 1, 3), the temperature expansion (shrinkage) compensating device 6, located at the rear of the chamber, shrinks under the action of inertial forces from the thermobaric mixture 3 and acts as a damping device to unload thin-walled housings 1 and 2.

In the encounter with a barrier, the temperature expansion (shrinkage) compensator 6 located in front of the chamber (Fig. 2,3) shrinks under the action of inertial forces from the thermobaric mixture 3 and acts as a damping device to unload thin-walled housings 1 and 2 until the explosive device 5 initiates the bursting charge 4, the detonation products of which tear the inner housing 2 disperse and ignite the homogeneous thermobaric mixture 3.
