Description

The invention relates to military equipment, mainly to tactical systems of high-precision weapons (WTO) of the class "surface-to-surface" based on ballistic homing ammunition, including rockets (PC) for the destruction of the second echelons and communications of the enemy.

Known methods of destruction of manpower, equipment, structures and communications by undermining high-explosive fragmentation warheads (OFBCH) ammunition. At the same time, as a rule, the fragmentation fragmentation of the OFBCH (with the primary defeat of the target by a stream of high-speed high-temperature fragments) is expedient to destroy manpower, unarmored and lightly armored enemy equipment, and a high-explosive detonation - to destroy structures and destroy the hard cover of communications.

There is a method of undermining OFBCH, rational in terms of configuration of the fragmentation field. With regard to ballistic ammunition, it consists in using steep trajectories of approach to the target and undermining the OFBCH directly above the surface of the earth when a screen effect occurs when a shock wave falls / reflects and rebounds fragments on the surface. To this end, the so-called predictor - see, for example, A.V. Babkin, V.A. Veldanov, E.F. Gryaznov and others. "Means of destruction and ammunition" (under the editorship of VV Selivanov), M., publishing house of MSTU. N.E. Bauman, 2008, pp. 279-280, 283 (analogue method).

A technical solution is known that makes it possible to use a standard head-mounted WU of "instant" action when varying the time of slowing down the detonation of the warhead of a PC, including with a roll-stabilized head compartment — the control unit (UB), which ensures, in particular, maximization of the high explosive separation effect OFBCH — see, for example, RF patent No. 2164657 (priority from 10/06/1999) - the closest analogue.

However, the technical device - the closest analogue does not provide a situational (depending on the type of specific target being hit) conversion type of detonation (fragmentation or high-explosive) of the warhead of the WTO ammunition.

The aim of the invention is to give homing ammunition, including with a roll stabilized UB, equipped with a leading “instant” action vehicle, a new quality of situational transformation such as blasting (fragmentation or high-explosive) OFBCH according to the command of the onboard control system (CS), which is formed depending on the type of target.

This goal is achieved by the fact that the UB is equipped with an aerodynamic needle (AI), which is supported on the firing pin, while for fragmentation detonation of the UHFB, at the moment of UB impact on an obstacle, they are unlocked by calibrated force and the AI is sunk into the UB body coaxially with its longitudinal axis up to the impact the drift on the WU, and for a high-explosive detonation of the OFBCH, on the command of the SU UB, the AI hard wedge in the UB case. Moreover, in some cases, the end of the AI directed towards the VU is performed in the form of a striker. Additionally, AIs are mechanically weakened along an oblique section with an angle of inclination to the longitudinal axis of the AI of 15 ° ... 75 ° (followed by the sinking of the broken part of the AI into the UB case past the “striker-VU” zone).

Examples of devices that implement their work (functioning) in accordance with the proposed technical solution are presented in figures 1, 2.

Designations accepted:

1 - control unit;

2 - landing nest of UB;

3 - UB control system;

4 - aerodynamic steering wheel UB (option);

5 - firing pin;

6 - aerodynamic needle UB;

7 - clamp for calibrated force (option);

8 - controlled lock for a hard AI spell;

9 - PC case (OFBCH compartment);

10 - explosive charge OFBCH;

11 - head explosive device OFBCH.

The functioning of the devices according to this technical solution is as follows.

The control unit pos. 1 is mounted with its mounting socket pos. 2 on the case pos. 9 PC (while the case pos. 9 is also a shell of OFBCH). In the elongated bow of the landing nest pos. 2 UB are located: on the one hand, the head VU pos.11 of the "instant" action OFBCH, on the other hand - the striker pos.5. In this case, the control unit pos.11 is fixed in a standard manner rigidly in the housing pos.9, and the striker pos.5 is prevented from moving by the clamp pos.7, designed for a calibrated shear force (for example, a mechanical ring or key type). A similar retainer pos. 7 keeps the aerodynamic needle pos. 6 from moving along the elongated bow of the landing seat pos. 2 (see Fig. 1). In this flight configuration of the AI-Boy-VU complex, the PC moves along the path and enters the target zone.

In the target zone, after its selection and identification, according to the commands of the control unit pos. 3 of the control unit, a homing step is carried out, for example, using the aerodynamic rudders pos. 4 UB to maneuver the PC (approach of the PC to the target in a given range of angles). The identification of the target allows the control unit pos. 3 to choose the type of firing of the OFBCH - fragmentation or high-explosive.

In the case of the implementation of the fragmentation detonation OFBCH, the flight configuration of the AI-Boek-VU complex remains unchanged. At the same time, at the moment of impact on the AI obstacle pos.6, telescopically moving along the elongated bow of the landing slot pos.2, it is guaranteed to cut off the retainer pos.7 and affect the striker pos.5. In turn, the firing pin pos.5 also cuts off its latch pos.7 and impacts on the VU pos.11 OFBCH. Next, the operation of the VU pos. 11 and the detonation of the explosive charge pos. 10 OFBCH occurs.

Since the presented rigid mechanical connection of the AI-bay-VU complex provides the fastest possible passage of a deformation wave upon impact of a shock wave against an obstacle, the OFBCH is undermined directly above the earth's surface with the formation of a rational configuration of the fragmentation field formed.

In the case of the implementation of a high-explosive destruction of the OFBCH, the control system pos. 3 of the control unit pos. 1 issues a command for the AI spell pos. 6 by means of a controlled lock pos. Option: by means of a controlled lock pos. 8, only the aft part of the AI is jammed, pos.6 (see figure 2). At the same time, at the moment of the impact of the aerodynamic needle pos.6 on the obstruction, the oblique section mechanically weakened (for example, by direct bombardment by high-energy particles) provides a programmed (in the right place) AI fracture and subsequent fundamentally misaligned displacement (including recession into the body UB pos. 1) of the AI head fragment - guaranteed past the zone of “strikers pos. 5 - VU pos. 11.

Stuck "rigidly" at the command of control unit pos. 3 with the controlled lock pos. 8 AI pos. 6 (or stern fragment of AI) together with the striker pos. 5, which is held by the detent pos. 7, only then they begin to shift towards the control unit pos. 11, when they reach a deformation wave of general collapse of the construction of the UB pos. 1 (option: directed to the VU pos. And the end of the AI pos.6 is performed in the form of a striker; the nature of the destruction of the structural elements of the UB pos. 1 is similar to the above). During this time period, the ammunition, the speed of approach of which to the target is hundreds of meters per second, will have time to penetrate into the obstacle (soil) to a length of 10 ... 20 calibers. In this case, the optimization of the depth of time, carried out during the development of ammunition, is carried out by varying parameter 5 - the distance between the striker pos.5 and VU pos.11 (see figure 1). Subsequent undermining of the OFBC will cause catastrophic collapse destruction, for example, of a building, or the formation of a deep funnel in the ground with the corresponding destruction of the hard road surface (in this case, the realized penetration depth of such ammunition into the ground prevents the appearance of camouflages). In this case, the main destructive (damaging) effect will be the high-explosive effect of undermining the OFBCH.

The implementation of the proposed technical solution seems appropriate for promising WTO ammunition equipped with AI and “intelligent” on-board control systems with homing heads, including operating in different spectral ranges, with matrix sensitive elements, - as part of an operational situational transformation of the type of detonation (fragmentation or high-explosive) OFBCH with serial WUs of "instant" action depending on the type of target (target). Which, in turn, will lead to a qualitative increase in the effectiveness of the WTO ammunition without any significant hardware complication of the design and configuration of the UB.
