Description

The invention relates to ammunition, and more specifically to targeted fragmentation warheads with a mostly directed forward (beam) of ready-to-use striking elements (GGE).

In the monograph by R. Lloyd "Physics and Design of Conventional Warheads", a series of "Progress in Astronautics and Aeronautics" vol. 179, ed. American Institute of Aeronautics and Astronautics, 1998, describes the design of the so-called gimbal warhead (gimbaled warhead). The warhead (warhead) contains a body with a charge of explosive, provided at the rear with a gimbal that connects the warhead with a rocket. At the front end of the warhead is a layer of GGE. Targeting is performed by rotating the warhead around the suspension.

To provide the necessary aiming angle, i.e. the angle between the axes of the warhead and the rocket, the diameter of the warhead should be significantly less than the internal diameter of the rocket, which leads to a decrease in the contact area of the explosive charge with the GGE layer and ultimately to a decrease in the mass and kinetic energy of the GGE flow. This is the main disadvantage of the gimbal system.

The closest analogue of the claimed invention is a targeted beam warhead of a guided missile containing a movable body with a charge of explosives, at the end of which, facing the bow of the rocket, a metal striking unit is placed (RU 2032139 C1, publ. 03/27/1995). The disadvantage is the same as that of the analogue.

The objective of the invention is to remedy this drawback.

The technical solution consists in the fact that the aimed beam warhead of the guided missile contains a movable body with a charge of explosive, at the end of which, facing the bow of the rocket, a metal striking unit is placed. The warhead is made in the form of a cone with the possibility of spatial movement of its top inside the missile body, while the metal striking unit is placed on the base of the cone, the diameter of which is close to the internal diameter of the rocket body.

In particular embodiments of the invention, a hinge connected to the drive of the control compartment is located at the apex of said cone. The metal striking unit is made in the form of one or more layers of finished striking elements. Ready damaging elements are made with the possibility of their dense laying in the layer. Ready striking elements are made of heavy alloy. The metal striking unit is made in the form of a round plate with extruded hemispherical recesses facing the tops to the explosive charge. A round plate made of low-density material is placed inside the explosive charge along its axis. The metal striking unit is made with a diameter smaller than the diameter of the base of the cone. The metal damaging unit is made in the form of a spherical segment.

Figure 1 - the initial location of the warhead in the nose compartment; figure 2 - targeted arrangement of warheads; figure 3 - targeted location warhead in the middle compartment of the rocket; figure 4 - embodiments of the warhead; figure 5 - versions of the drive; Fig.6. 7, 8 - action diagrams of the warhead.

Figure 1 shows a diagram of the initial location of the warhead in the nose compartment of the rocket 1, figure 2 - the target position of the warhead. The warhead contains a housing 2 with an explosive charge 3 and a detonator 4. In the rear of the hull is a hinge 5 connecting the warhead with the actuator rod 6, protruding from the control compartment 7. At the front end of the explosive charge is a layer (block) of GGE 8, made from steel or heavy alloys based on tungsten, tantalum, etc. GGE can be made in a form that ensures their tight packing in the block. In figure 1, 2 conventionally shown GGE in the form of balls. The diameter of the base of the conical warhead is close to the inner diameter of the rocket body.

The nose compartment housing is made of light alloy in the form of a thin-walled structure that does not impede the passage of the GGE stream. The design of FIG. 1 provides lesion in the entire front hemisphere.

Figure 3 presents the warhead in the form of a truncated cone (shown in the aimed position).

In this case, the warhead is located behind the control compartment 9 with the rudders 10, which complicates the defeat of targets in the area located along the axis of the rocket. A possible way out is to reset the control compartment before undermining the warhead.

Figure 4 presents various versions of the warhead. The warhead shown in Fig. 4, a, is equipped with a plane detonation wave generator, consisting of an external charge in the form of a hollow cone 11 made of explosives with a high detonation velocity D ₁ and an internal charge in the form of a solid cone 12 made of explosives with lower detonation velocity D ₂ , and both speeds are related by the ratio

D ₂ = D ₁ cosα,

where α is the half-angle of the cone.

Another embodiment of a plane-wave generator is presented in figure 4, b. In the explosive charge, a cavity 13 is made in the form of a spherical segment facing the convex side to the apex of the cone, the convex side of the cavity being covered with a thin layer of metal 14 (lining).

In the charge of the warhead of FIG. 4, a circular plate 15 (explosion-proof lens) made of a light inert material is placed in the axis of the charge. At the same time, the GGE block 16 is multilayer with a decrease in the diameters of the GGE laying layers in the direction of the explosive charge.

In the design of FIG. 4, d, multipoint initiation 17 of the rear end of the charge in the form of a round plate with extruded hemispherical recesses 18 facing the vertices of the explosive charge is applied.

In the design of FIG. 4, d, a metal damaging block, in this case a multilayer block GGE 19, is made with a diameter smaller than the diameter of the cone base. The explosive charge forms the headband 20.

In the construction of FIG. 4, the e metal striking unit is made in the form of a round plate 21 in the form of a spherical segment designed to form an impact core.

Schematic versions of the drive of the warhead are shown in Fig.5. Figure 5, a shows a drive with two-axis (angle-radius) movement of the hinge along a straight guide 22, figure 5, b - with movement along a curved guide 23 (24 - targeting unit), figure 5, c - movable joint 25, figure 5, g - a system of independent pushers 26.

The warhead is designed primarily for use in anti-aircraft guided missiles and can hit both aircraft and tactical ballistic missiles. When approaching the target, the side and magnitude of the miss and the relative speed are determined. Based on these data, the on-board computer calculates the optimal coordinates of the detonation point and the required orientation of the warhead axis at this point.

The drive provides the required orientation of the warhead, after which it is undermined at the design point. A direct drop of the detonation wave onto the GGE block provides a high speed of GGE throwing. The angle at the top of the beam depends on the type of construction of the warhead. Designs with a plane-wave generator (Fig. 4, a, b) create a plane detonation wave, which leads to a decrease in the beam angle and an increase in the density of the GGE flow. A similar result is provided by the constructions of Figs. 4, c and d. The latter implements the so-called multicumulative ("meniscus") scheme with the formation of many high-speed shock nuclei.

The diagram of figure 4, d with the headband 20 of the BB is also intended to reduce the angle of expansion of the GGE.

The scheme of figure 4, e with the formation of the impact core can be applied while ensuring high accuracy of aiming. The scheme with multipoint initiation (Fig. 4, d) allows taking into account the meeting conditions in order to control the angle of expansion of the GGE.

The defeat schemes of air and ground targets are shown in FIGS. 6 and 7, respectively (V _B is the speed of the attacking unit relative to the rocket, V _OTH is the speed of the rocket relative to the target, V _p is the speed of the rocket, C is the target). On Fig shows the action of the warhead on a target located directly at the heading of the rocket, with the shooting of the head control compartment.

The technical result is to increase the probability of hitting a target with a given mass of the warhead. The transition from combat units with a circular field to directed combat units is consistent with the current trend in the development of weapons.
