Description

The invention relates to the field of weapons, namely, to the design of the warheads of anti-tank guided shells, in the initiation units of which a detonation generator is used.

Known initiation unit with a detonation generator, including a cylindrical body and a lid, the inner cavity of which is filled with a plastic explosive charge (see patent No. 2150660, July 29, 1999, class F 42 V 1/024).

The closest in technical essence to the claimed technical solution is a detonation generator, including a cylindrical body and a cover, the inner cavity of which is filled with a plastic explosive charge. The plane of the docking cover with the housing coincides with the front end of the housing. A cover with a sealed bottom, in addition to its main purpose, acts as a lens, preventing the transfer of detonation to the central part of the main charge (Explosion Physics / Ed. By L.P. Orlenko. - Ed. 3rd, revised. - T.2. - M .: FIZMATLIT, 2002, p. 298-299, Fig. 17.89).

The disadvantages of the known designs is that during the final assembly of the warhead (warhead) along the generator’s seat in the warhead housing, a radial clearance is formed, as a result of which the alignment of the generator’s base relative to the warhead housing is violated, which in turn leads to instability of the cumulative charge.

The objective of the technical solution is to increase the penetration and stability of the combat units.

The specified technical result in the implementation of the invention is achieved by the fact that in the detonation conical generator of the initiation unit of the cumulative charge containing the housing, cover, lens and ring striker, the cover is made in the form of a truncated cone, the position of the plane of docking with the housing is behind the ring striker, and the conical part of the cover The curb generator is precision based in a similarly shaped seat coaxial with the warhead housing. In addition, the lens is made of a plastic material with elastic properties.

The plane of the docking of the lid with the body, unlike the known structures, is transferred beyond the annular impactor-groove made on its conical surface. As a result of this, the lid in the running generator is a supporting structure, due to which the gapless precision alignment of the generator relative to the warhead housing is ensured during final assembly.

In addition, on the flight path of the projectile, the lid perceives overloads arising from the disclosure of stabilizers and rudders. According to the proposed design of the generator cover, the design of the support pressed into the housing, in which the seat for the generator is made on a cone, has been changed. To ensure that the conical generator fits exactly on the cone, a guaranteed clearance must be maintained between the end face of the generator cover and the support technological base (In FIG. 1) for counting the position of the generator after pressing in. Since the specified gap is not a constant value and varies depending on the combination of manufacturing tolerances, the size of the lens height is selected so that after pressing the generator in, the lens due to its elastic properties is pressed and does not have freedom of movement in the axial direction.

The invention is illustrated by drawings, where figure 1 shows in longitudinal section an equipped conical generator assembly with parts of the warhead; figure 2 shows a conical curb generator; figure 3 shows the cover of the generator; figure 4 - the housing of the generator.

The site of initiation of the cumulative charge consists of a detonation generator 1, lens 2, nut 3, support 4 and fuse 5. Support 4 is pressed into the housing 6, thereby ensuring alignment of the seat under the generator 1 relative to the housing. The main charge briquette 7 is pressed in the housing with the support simultaneously with the cladding 8. The equipped detonation generator is shocklessly installed in the conical seat of the support 4 until size A is secured and fixed with a nut 3. Lens 2 is installed in the internal cavity of the support before the generator is pressed in. When the generator is equipped (figure 2), the internal cavity formed during the assembly of the cover and the housing is filled with a plastic charge 9.

Functionally, the mass of the generator’s charge is divided into the following components: centering charge 10, distributing charge 11, initiating propellant charge 12.

The ring drummer 13 is a conical ring of the cap (bottom of the groove), which is affected by a propelling charge, causing detonation of the main charge from the periphery.

The detonation conical generator of the site of initiation of the cumulative charge works as follows.

When the fuse 5 (Fig. 1) is triggered, the initiating pulse of the latter is transmitted through the centering charge 10 (Fig. 2) to the distributing 11, which in turn drives the initiating charge 12. Under the action of the initiating charge, the annular gap between the striker 13 and the screen (part walls of the conical support) closes within ~ 0.4 μs, the projectile accelerates to a speed of the order of 2750 m / s, and a detonation front is formed along the periphery of the main charge. At the same time, lens 2 prevents the transmission of detonation to the central part of the main charge.

Due to the fact that the detonation generator is precisely aligned relative to the axis of the body (the axis of the main charge), a converging detonation front of a symmetrical shape is formed in the form of a toroid without displacement of the axis of symmetry of the detonation front and charge 7. Under the action of detonation, the cumulative lining 8 collapses and a cumulative jet is formed the correct form without its deformation and curvature, penetrating the armored target.

Thus, the use of the proposed detonation conical generator of the site of initiation of the cumulative charge will increase the stability of the warhead and increase armor penetration.
