Description

The invention relates to cumulative ammunition.

Known cumulative charges containing an explosive bomb / hereinafter BB / with a cumulative recess having a lining, see US Pat. Russia №2062433. However, the possibilities of such charges are not fully exhausted. The explosive nature of the combustion reaction of a mixture of ammonium nitrate with aluminum powder / ammonium / or with diesel fuel / ammonite /, that is, even in dispersed and heterogeneous systems, suggests that the rates of redox reactions at the pressures and temperatures that are obtained when the cumulative stream in contact with the obstacle / speed up to 150 km / sec /, can be large enough to significantly affect the armor penetration of the charge.

Invention 1. Its essence is that in the lining, and therefore in the cumulative stream, there are metal compounds in the voltage range / it is also the “reduction row” / to the right of the metal, which mainly consists of armor.

If metal oxide is used, the reaction between it and the base metal of the armor, which is usually iron, will be similar to the termite “burning” reaction, that is, metal reduction reactions are similar to aluminothermy reactions. Since the reaction is exothermic, due to the heat generated, the armor metal in the contact zone with the cumulative jet is additionally heated, and its toughness decreases. The iron oxides formed as a result of the chemical reaction also have a lower toughness. As a result of this, the armor penetration of the charge will increase and its armored effect will increase.

In this case, the cumulative jet will be dispersed, "semi-gas" and its density will be less than that of, say, tantalum. Which, however, is offset by its much greater speed.

The metals chosen, as already mentioned, should be in the series of stresses to the right of the iron, and their compounds should have a sufficiently high density, since the main way of destroying the armor is still the effect of the kinetic energy of the cumulative jet on it.

Mercury oxide has the best range of characteristics.

The invention 2. For example, the cumulative charge may contain a solid oxidizing agent, entering into an exothermic reaction with the armor with the formation of substances with lower impact strength. Such compounds can be non-metal oxides / iodine oxide, alpha-sulfur trioxide, phosphorus pentoxide, nitrogen pentoxide under overpressure /. As well as peroxides, superperoxides, ozonides, perchlorates, metal permanganates.

Invention 3. Sulfur, halogens, phosphorus, and halogen compounds can also react with armor metals with each other, either with sulfur or with phosphorus.

The binder may be the explosive itself.

Example 1. Mercury oxides / red and yellow / 11.08-11.03 g / cm ³ have a good density. The binder may be BB. Two reactions will take place simultaneously - the thermal decomposition of mercury oxide with the formation of active oxygen and the reduction reaction of the metal, which is in a series of voltages to the right of iron. In order for all mercury oxide to decompose ahead of time, it must be in the lining in a sufficiently coarse state. Both reactions produce mercury with a density of 13.6 g / cm ³ and iron oxides.

Example 2. The lining includes cesium peroxide. Binder - BB. Upon decomposition of superperoxide, free oxygen binds to iron.

Example 3. In the lining there is alpha sulfur trioxide. When decomposed, it reacts with iron and forms iron oxides and sulfide.

Example 4. In the lining there is iodine bromide. When decomposed, it reacts with iron and forms iodide and iron bromide.

Example 5. In the lining there is crystalline boron. As a result of interaction with iron and other armor metals, borides are formed.
