Description

The invention relates to the field of armaments and can be used in the construction of warheads (warheads) of missiles and other ammunition equipped with explosive compositions (hereinafter - warheads).

A known design of warheads according to the patent RU 2106596 C1, according to which the external all-metal shell (CMO) is crushed into damaging elements (PE) of predetermined sizes due to finished PEs laid internally with gaps between each other, as well as a gap between the CMO and finished PEs filled with an inert gasket.

A known design of warheads according to the patent DE 19809181 C1, according to which the external CMO is crushed into PE of a given size due to the finished rectangular PE or their blocks placed between the CMO and the explosive charge (RE) with the arrangement of their ribs at an angle of 45 degrees to the generatrix, with radial clearances between the faces of PE or their blocks. Finished PE and the gaps between them are separated from the RE with a thin-walled lining.

The design of warheads according to patent DE 19753188 A1 is known, according to which crushing of ring fragments of the external CMO into PE of a given size is ensured due to the rings of finished rectangular PE laid inside the CMO.

The last technical solution, as the closest in technical essence and the achieved result, was chosen as a prototype.

The disadvantages of analog structures should be considered as follows.

In the design according to the patent RU 2106596 C1, due to the presence of gaps between the finished PEs in the transverse and longitudinal sections and due to the inert gasket between the CMO and the finished PEs, the quantity and mass of finished PEs laid inside the CMO is significantly reduced, as well as the speed of PE expansion.

In the design of DE 19809181 C1, the laying of finished PEs at an angle of 45 degrees to the CMO generatrix with the provision of gaps between all faces of adjacent PEs or their blocks is technologically difficult and due to the presence of the said gaps, the number and mass of finished PEs laid inside the CMO decreases.

According to the technical solution according to the patent DE 19753188 A1, it is doubtful that its use will ensure organized crushing of the CMO into fragments of a given size at the joints of the rings of finished PE.

When undermining the RE of the warhead prototype of the CMO and adjacent ready PEs inside it begin to move in the radial direction, while:

- detonation products erupt into the formed gaps between adjacent PEs of each transverse row (coil) of finished PEs and form longitudinal cuts on the inner surface of the CMO, along which organized further crushing of the CMO occurs with further radial movement;

- in the central zone between the transverse rows (turns) of the finished PE, gaps are practically not formed, and in the end zones gaps of small width are formed due to the end unloading of detonation products and the corresponding cross-cuts of insignificant depth are formed, the organized crushing of CMOs by which is problematic;

- thus, between the ends of the longitudinal complete cuts, there are un-cut or slightly cut bridges in sections at the junction of the transverse rows (turns) of finished PE, the width of these bridges varies equally from zero to the width of the finished PE.

, где n - количество готовых ПЭ в одном поперечном ряду (витке), и за счет этого обеспечивается дробление ЦМО. Однако из-за практического отсутствия углов между векторами скоростей у соседних ПЭ от ЦМО над соседними рядами (витками) готовых ПЭ, а также из-за наличия по местам стыка поперечных рядов (витков) готовых ПЭ между образующимися из ЦМО ПЭ неподсеченных перемычек шириной более ширины половины готового ПЭ, ЦМО по месту стыков поперечных рядов (витков) готовых ПЭ дробится не регулярно и образуется большой процент сдвоенных, строенных и т.п. осколков из ЦМО. Это объясняется тем, что перемычки шириной менее половины ширины ПЭ разрушаются стабильно, а при их ширине более половины ширины ПЭ, особенно при ширине, близкой ширине ПЭ, часто не разрушаются.With further radial movement, neighboring CMO sections separated by hooks above each transverse row (turn) of finished PEs move relative to each other at an angle equal to the ratio

, where n is the number of finished PEs in one transverse row (coil), and due to this, crushing of the CMO is ensured. However, due to the practical absence of angles between the velocity vectors of neighboring PEs from the CMO over adjacent rows (turns) of finished PEs, as well as due to the presence at the junctions of the transverse rows (turns) of finished PEs between unsigned jumpers with a width greater than width half of the finished PE, CMO at the junction of the transverse rows (turns) of the finished PE is not crushed regularly and a large percentage of double, built, etc. shards from the CMO. This is because the jumpers with a width of less than half the width of the PE are destroyed stably, and with their width of more than half the width of the PE, especially with a width close to the width of the PE, they often do not break.

The technical result, which the invention is directed to, is:

- to increase the efficiency of warheads by ensuring the stability of crushing of the outer cylindrical CMO on PE of the required sizes and masses, including crushing into fragments of specified sizes and along the generatrix of the CMO at the joints of the transverse rows (turns) of finished PE;

- to increase the manufacturability of the warhead casing by providing the required crushing of the CMO without performing corrugations on it;

- to increase the strength of the warhead housing with CMO with the exclusion of transverse corrugations on it with a decrease in their depth.

The specified technical result is achieved in that, in contrast to the known warhead containing a RE and a housing in which finished compact PEs are adjacent to the inner surface of the CMO with their rectangular faces, two design options for the warhead are proposed.

In option I, adjacent to the CMO PE in adjacent transverse rows (turns) are offset relative to each other by half their width. Between the faces of adjacent transverse rows (turns) of finished PE gaps are made.

In option II, ready-made PEs adjacent to the CMO are arranged in longitudinal rows at an angle from zero to 5 degrees to the generatrix. In the end zones of the assembly of finished PE, between the faces of adjacent transverse rows, gaps are made that determine the length of the formed rods when undermining the RE.

No analogues having features similar to the claimed solutions were found; therefore, it can be considered that the claimed devices are new and have a sufficient inventive step.

The essence of the proposed technical solutions is illustrated by the drawing.

Figure 1 shows a longitudinal section of the warhead, which includes the outer layer of PE in the form of a predominantly smooth-walled CMO 1 adjacent to the inside of the CMO layer 2 of compact rectangular PE and RE 3.

Figure 2 shows a scan view of adjacent to the CMO layer 2 of finished PE with rectangular faces. In adjacent transverse rows (coils), the faces of adjacent PEs are shifted relative to each other by half their width “A”. If it is necessary to increase (for example, doubling) the mass obtained from CMO 1 PE, this displacement can be performed not at each joint of adjacent transverse rows (turns), but, for example, through 1 joint (see the right part of the image in figure 2).

Figure 3 shows a sweep of the view on the inner surface of the CMO 1 in the initial period of expansion of PE warheads with the laying of finished PE 2 of figure 2. Sweeps 4 on CMO 1 were obtained from the joints of each pair of PE 2 located along the generatrix of the shell. “B” and “G” are a pair of PE 2 formed from CMO 1 over adjacent transverse rows (turns) of PE 2.

Figure 4 shows a scan view of PE 2 with rectangular faces, laid in longitudinal rows at an angle α of up to 5 degrees to the generatrix of CMO 1.

Figure 5 shows a view of PE 2, laid in longitudinal rows at an angle of up to 5 degrees to the generatrix, while the transverse gaps “D” are made between the PEs in the end zones.

The proposed design options work as follows.

When undermining the RP warhead according to option I (with the laying of PE 2 in accordance with figure 2) in the initial period of the radial movement of the CMO 1 and PE 2 on the inner surface of the CMO longitudinal cuts are formed in accordance with figure 3, while the width of the unsectioned jumpers “B ”Between the ends of the longitudinal hooks in the section at the contact point of the transverse rows (turns) of PE 2 will be the same and equal to half the width“ A ”of PE 2.

With further radial movement, the CMO begins to fragment according to the cuts, while the separation of PE 2 formed from the CMO corresponding to adjacent transverse rows (turns) of PE 2 (zones “B” and “G”, see FIG. 3) is ensured by following factors:

- to separate zone “B” in one transverse row from zone “G” in the adjacent transverse row (see Fig. 3), it is necessary to destroy the jumper “B” between them of the same width for all PE formed (unlike analog structures, in which this size can vary from zero to the width of the finished PE 2);

, где n - количество ПЭ 2 в одном поперечном ряду (витке). Например, при БЧ калибром 93 мм, внутреннем диаметре ЦМО 1 (см. фиг.1) 86 мм, размере примыкающей к ЦМО грани готового ПЭ 9×9 мм² в одном поперечном ряду укладывается 30 готовых ПЭ и угол между векторами скоростей образующихся из ЦМО соседних ПЭ над рядом расположенными поперечными рядами (витками) готовых ПЭ составляет

.- velocity vectors for formed from CMO 1 of any pair of PE “B and“ G ”(see figure 3) are directed at the same angle to each other, equal to the ratio

where n is the number of PE 2 in one transverse row (coil). For example, with a warhead caliber of 93 mm, an inner diameter of CMO 1 (see Fig. 1) of 86 mm, the size of the face of the finished PE 9 × 9 mm ² adjacent to the CMO, 30 finished PEs fit in the same transverse row and the angle between the velocity vectors formed from the CMO neighboring PE over adjacent transverse rows (turns) of finished PE is

.

For warheads according to option I, taking into account claim 2 of the claims, the separation of PE from CMO from zones above adjacent transverse rows (turns) of PE 2 will also improve due to the formation of transverse hooks on the CMO at the initial stage of radial expansion of the assembly above the gaps over the joints of the transverse rows (turns) of PE 2. The total length of these gaps is approximately half that of the analogue design of DE 19809181 C1.

In the warhead according to option II (with PE 2 laying in accordance with FIG. 4), at the initial stage of the radial expansion of CMO 1 and PE 2 between the longitudinal rows of PE 2 laid at an angle from zero to 5 degrees, gaps are formed into which the detonation products break and longitudinal cuts corresponding to the joints of the longitudinal rows of PE 2 are formed on the inner surface of the CMO 1. With further radial movement, the CMO 1 is split up along the sweeps into rods oriented at an angle corresponding to the angle of laying of the longitudinal rows of PE 2 to the generatrix. Due to this, during expansion, each rod of the CMO rotates around its center of mass and rotates 90 degrees at the calculated radius. Thus, from CMO 1, a lesion field (PP) is formed in the form of a core ring.

If the longitudinal rows of PE 2 are laid along the generatrix of the CMO (α≅0, see Fig. 4), then the rods obtained from CMO 1 will create PP from rods flying without rotation parallel to each other.

When laying PE 2 in accordance with FIG. 5, under the detonation of RE 3, the CMO 1 is additionally undercut by detonation products breaking into the gaps “D”, and the ends of the formed rods from these undercuttings break off from the rods of the required length in the form of fragments.

The design of the warhead according to option I according to claim 1 of the claims will provide stable crushing of CMO on PE of the required size and weight:

- at relatively small thicknesses of the CMO at any elongation (ratio of length to diameter) of the warhead;

- when the thickness of the CMO, commensurate with the thickness of the adjacent layer of the finished PE, and with elongation values less than 1, because Due to the end-face unloading of RE detonation products along almost the entire length of the CMO in the initial period of the radial movement of the PE assembly, gaps are formed between the faces of adjacent transverse rows (turns) of finished PE and the corresponding cross-cuts on the CMO.

The design of the warhead according to option I, taking into account claim 2 of the claims, will ensure crushing of the CMO 1 into PE of the required size and weight for any values of elongation of the warhead at reasonable ratios of the thickness of the CMO to the thickness of the adjacent layer of the finished PE.

The values of the gaps between the transverse rows (turns) of PE 2 to ensure the necessary depth of transverse hooks must be selected for each specific warhead, depending on:

- from the thickness adjacent to the CMO 1 layer of finished PE;

- from CMO material intended for organized crushing (steel, titanium or aluminum alloys, etc.);

- on the magnitude of the extension of the warhead, including from the relative amount of removal of a particular joint of the transverse rows (turns) from the end of the RE.

The use of options for the proposed design warheads in comparison with the prototype allows you to:

- increase the efficiency of warheads with CMOs by ensuring stable crushing of CMOs on PE of the required size and weight;

- to improve the manufacturability of the warhead casing while ensuring the required crushing of the CMO without performing corrugations on it;

- to increase the structural strength of warheads with CMO with the exception of performing corrugations on it or when performing smaller corrugations.
