Technical field

The invention relates to a grenade with a multifunctional warhead fired from smooth-bore or rifle weapons such as grenade launchers, mortars, single or multi-barreled launchers (devices) and others whose warhead is designed to defeat live forces, combat equipment and the enemy's fortified facilities simultaneously by thermobaric volumetric action, cumulative and fragmentary puncture action.

The warhead of the grenade can also be used independently, shaped as an artillery projectile for barrel artillery.

BACKGROUND OF THE INVENTION

For the destruction of manpower, combat equipment and reinforced enemy engineering facilities in the armies of all countries, conventional ammunition with different striking action and corresponding purpose is used, such as cumulative, fragmentation, fragmentation, cumulative-fragmentation, thermobaric and other types of ammunition. 1], [2], [3], [4], [5], [6], [7], [8] and [13]).

The anti-tank ammunition [1] consists of a reactive grenade with a cumulative warhead and coupled to its jet engine at the rear by a propellant charge in a sleeve. The cumulative warhead is made up of a cylindrical-conical housing with a standard shaped cumulative charge with a metal lining located therein, the back of a socket on which the bottom of a piezoelectric fuse is placed, and a front part of the hood is mounted on the hull. The jet engine is fitted with a multi-percussion stabilizer at the rear, which dissolves after the grenade launches.

The ammunition known from [2] is, in turn, composed of a fragmentation grenade and coupled with it a projectile charge in the liner used for launching it. The grenade itself is made up of a warhead assembled in front of one another and an elongated multipurpose stabilizer at the rear. The warhead is a monolithic cone-cylindrical metal body ending at the bottom with a bursting explosive charge, with the warhead fitted with a front fuse.

Ammunition [3] and [4] of high-explosive type are known. According to the information available to the ammunition [4], it consists of a high-explosive grenade and a propelled gunpowder connected to it from behind. The grenade is made up of a jet engine and coupled to it in front of a warhead comprising steel rings with a predetermined fragmentation of fragments and a bursting (bursting) charge of a powerful explosive explosive or an explosive blend of high explosive action. The warhead is fitted with a front impact blower.

Ammunition [5] and [6] with a combined cumulative fragmentation effect are known. As far as ammunition can be judged [6], it is similar to that used in previous ammunition [4], but its warhead contains a cumulative fragmented burst charge and shell rings located outside with pre-set fragmentation. The warhead is fitted with a piezoelectric front fender with an inertial liquidator.

Thermobaric type ammunition is presented in [7] and [8]. As far as one can tell, the latter is made up of a thermobaric type front mounted warhead and a standard jet engine coupled to it.

A review of these and other similar structures (see [13]) shows that, in the competition for dominance, ammunition manufacturers are constantly striving to increase the power of their striking action, in accordance with the increasing security of the defeated targets against the action of one or the other type of ammunition.

For example, infantry and other units of modern high-strength materials (bullet-proof vests, helmets, etc.) successfully protect the living force from the striking effects of traditional shrapnel and high-explosive ammunition by rapidly reducing the energy of spilled shards and products. the explosion from the site of the ammunition burst.

Similarly, the armor and other protection of tanks, other military equipment and reinforced facilities, using both new materials and appropriate design schemes, makes them less vulnerable to the effects of both high-explosive, cumulative and cumulative- fragmentation ammunition in the event of the latter being hit in places with enhanced protection. But in the case of access to their interior space through cracks, openings, trenches and other combat calculations, they are struck by shock waves of high thermobaric intensity penetrating the action of thermobaric ammunition.

On the other hand, the known thermobaric ammunition, which creates a high-explosive effect with several times increased volume in space against targets of open or light-protective type, is poorly effective against highly protected armored and other targets whose interior space is inaccessible to shock waves without penetration. they cannot be seriously affected by their protection.

The military-technical and military-economic analysis of these trends show that increasing the power of action of a particular striking factor for a given type of ammunition makes them disproportionately large in size (caliber) and with disadvantageous technical parameters and economic indicators relative to the achieved striking effect, which inevitably imposes certain structural and other constraints (the principle of reasonable compromise).

On the other hand, the separate use of the well-known ammunition of different types and combat purposes in the context of modern fleet fighting with a dramatic change in the type of targets struck and their security necessitates the supply of armies with a great variety of ammunition for each weapon system, and at the same time significant quantities of ammunition in the ammunition remain unusable.

The tendencies and prospects for building national and international military units with rapid response capability and maximum operational-tactical flexibility necessitate the creation of unified multifunctional ammunition with combined striking action provided through the use of new design schemes and elements in multiplier principle the introduction of two or more striking factors into one ammunition is carried out in such a way that the action of one of them is not limited, but enhances or further develops the action of others.

In part, these trends are reported in the ammunition grenade [6]. Along with a number of advantages, this grenade combines both types of striking action - cumulative and fragmentary, but obviously as a separate manifestation of each of them, without mutual reinforcement.

SUMMARY OF THE INVENTION

It is an object of the invention to combine the capabilities of conventional conventional ammunition with the use of new design schemes and elements in one ammunition in such a way that the main striking factors therein are combined and mutually reinforcing.

In pursuit of this behind the eye, the grenade according to the invention constructively provides the combined effect of the following major striking factors:

- fragmentary puncture action of fragments or striking elements (PEs) of defined geometry and mass, which are blown away by the action of the explosive products;

- cumulative breakthrough action, provided by an appropriately arranged cumulative charge;

- thermobaric volumetric action as a kind of enhanced explosive-ignition action by the use of standard thermobaric or newly proposed volumetric detonation thermobaric mixtures (TBS and OD TBS).

For this purpose, the grenade shall be equipped with a caliber or super-caliber (according to the weapon) warhead, coupled with a rocket engine or other element behind it, which acts as a means of launching and / or delivering the warhead to the struck single target or site. on the ground, both individually and with the help of additional throwing (starting) charge according to the design of the weapon.

The multifactor striking action of a grenade is provided by its warhead, which is arranged in such a way as to achieve complementarity and reinforcement of the various types of striking action.

For this purpose, in a monolithic steel housing, the tubular structure - a cumulative spreading charge (KRZ), representing a self-assembled unit, is provided.

The hull of the warhead is mechanically machined so that it is profiled by grooves (notches) of semi-finished PEs of defined geometry and mass.

The profile of the housing is achieved by longitudinal channels with triangular shape, executed with a certain step along the inner surface of the housing and also triangular screw or circular grooves, executed on the outer surface, their depth according to the fragility of the steel mark 0 being selected in the border of the mark 0 up to 0.40 of the body thickness.

The Cumulative Spray Charge (KRZ) is housed in a thin-walled tubular body, at the front end of which is an expanded cumulative charge chamber (KZ) with an outer diameter corresponding to the inside diameter of the warhead body, and the rear ends with an extended a cylindrical spreading charge chamber (P3) of smaller diameter constituting from 0.25 to 0.75 of the diameter of the shortening chamber. The two body parts are connected by a transitional cone.

An additional charge of phlegmatized hexogen, tan, or an auxiliary of explosives (BB) is pre-pressed in the area of the transitional cone in the body of the CRD, and a central socket is formed in the pressed BB in the size and shape of a conical or lens-shaped screen with a sleeve, bush-shaped screen. with the socket ending in a central opening for the screen sleeve.

The KZ itself is made of a preformed briquette of the same type BB pressed into the front chamber of the KRZ body with a metal lining placed in its cumulative cavity, ending at the top by a cylindrical neck with a central opening, in relation to which between the briquette and the additional charge is located and a center screen with a double-convex shape with a central opening and a metal sleeve so that the sleeve forms a socket at the rear of the extra charge. The fixing of the KZ is carried out by a thin-walled conical metal guard located in front of the body of the KRZ, ending at the front with a cylindrical neck with a central opening whose diameter is equal to or smaller than the opening in the metal cumulative lining, with the guard against it being pressed against it. in threaded housing of clamping ring.

To initiate a CRP, a metal or plastic capsule carrier with a central opening is tightly inserted in the sleeve of the screen sleeve, in which a detonator cap (k / e) with a flange is seated tightly so that its flange is facing in the direction of the screen.

The spreading charge (P3), consisting of one or more adjacent briquettes of high explosive or explosive pyrotechnic blast with a powerful brilliant, high explosive and inflammatory action, is located in the rear chamber of the body of the RHP and is fixed therein in a suitable manner, for example, by using a screwdriver in the thread of the body of the CRP press disk through a pad located between the disk and the charge.

The THR body threads at the turning points are sealed with selected sealing compositions.

A cone-shaped fairing ending with a threaded hole is installed in the front of the warhead housing by means of a sealing ring for sealing between the forehead and the fairing.

A metal bottom is installed to the rear of the warhead housing by means of a metal bottom, in which a central threaded hole and a connecting thread for the next grenade element are provided, with a sealing ring between the ends of the housing and the bottom. The free volume in the internal space between the body of the warhead and the body of the RHP is filled with a measured quantity of TBS or OD TBS with selected formulation, after which an adapted compensating device [9] is installed in the threaded hole in the bottom and the threaded connection is sealed with selected sealing compositions.

For the explosion of the so-described very functional front in the threaded bore of the fairing, a front fuse having a detonator with rear axial action was installed.

It is possible to arrange the multifunctional warhead using elements of standard cumulative or cumulative fragmentation warheads equipped with corresponding front or bottom piezoelectric fuses, for example fuses according to [2], [4], [10], [11] and [12], the adaptation of the borrowed elements being accomplished by appropriately designed details for their alignment and compaction at the attachment points.

The advantages of a multifunctional warhead grenade with a combined thermobaric and cumulative fragmentation action are the following:

- In a single structure, the main factors for conventional ammunition are functionally united by the striking factors: enhanced explosive action respectively of the TBS or OD TBS used, maximum cumulative penetration action and enhanced fragmentation action according to the caliber of the warhead.

- Combining in the proposed design of the combat unit in a common blasting process several types of striking action in such a way that they complement each other and intensify in comparison with their independent implementation, namely:

a) the presence of a high-intensity thermobaric explosive field in the immediate vicinity of the cumulative charge reduces the energy losses of the products of its detonation due to their limited side and backward spillage, thereby increasing the concentration of energy in the cumulative jet direction and accordingly it also increases the cumulative breakthrough;

(b) a similar cumulative action enhancing effect is obtained by the presence of additional mass of metal from the hull of the warhead in the charge zone;

(c) the magnitude of the thermobaric action zone several times larger than the side-diffusing aerosol particles of the TBS and the products of the bursting of the spreading and cumulative charges, which act in the subsequent volumetric explosion as a piston of the fragments formed during the fragmentation of the combat unit shell ), maintains and increases the kinetic energy stored in the fragments by distances from 1.5 to 3.5 times greater than usual for shell and ammunition shells. As a result, the breakthrough action of the fragments (PE) of the warfare increases from 1.5 to 1.7 times, and the actual area of damage from them even at targets with higher protection than the standard increases.

- Combined thermobaric and cumulative fragmentation multi-function combat unit can replace its caliber combat units in different-purpose ammunition, thereby obtaining the quality of unified multipurpose ammunition for different weapons systems, as well as using self-designed as a self-defense weapon. projectile.

There is no information about an analogue of the proposed grenade and its multifunctional warhead.

Use of the invention

The multifunctional warhead grenade in its embodiment according to FIG. 1, FIG. 3, FIG. 4 and FIG. 5 in storage and combat use, proceeds as follows:

When stored

The presence of liquid components in the composition of thermobaric mixtures predetermines greater coefficients of volumetric expansion or contraction at corresponding temperature changes than standard BB and explosive mixtures used for ammunition equipment. In the enclosed TBS 16, the volume of the warhead 26 causes changes, and at high (above 25 ° C) the compensating device 20 enables its expansion without creating increased internal pressures and at low (below 10 ° C) temperatures. - for its contraction, respectively, without creating sub-pressures and unfilled areas posing a certain risk of launching a grenade 1.

When shooting

The grenade 1 with the warhead 26 is fired as well as the standard ammunition, for example [2], with the use of a propellant charge.

When firing at certain initial speeds and accelerations, the front fuze 25 is introduced and the jet engine 42 is activated, which further accelerates the grenade 1 until it hits the target, opening its stabilizer fins after leaving the weapon, thereby ensuring the proper flight of the grenade 1.

The multifunctional warhead 26, after hitting the grenade 1 in the target (barrier), is actuated sequentially starting from the fuse 25, as the particles and products of the detonator blast pass through the guide hole in the neck of the fuse 6 and actuate the a / d 15, and it, in turn, detonates PZ 4 and thus KP 3.

In CK 3, a cumulative metal jet with a specific breakthrough action is formed from the lining 10, which penetrates the target (barrier) and punctures it. Under the influence of excessive pressure from the products of the explosion of the briquette 36 and the additional charge 35 in the KZ 3, as well as the briquettes 17 and / or 24 in the PZ 4, the housing 11 is destroyed along the grooves (notches) profiled therein. The formation of fragments (PE) and aerosol cloud from OD TBS followed, creating a volumetric explosive field, saturated with splinters and detonating aerosol mixture, penetrating all available slots, openings, channels, trenches and other in combat equipment, fortified facilities. and the area. Thus, at the same time as the breakthrough action of KZ 3, a powerful fragmentation and high-inflammatory striking action is provided.

Obviously, the ability to perform by combining individual elements of the various embodiments according to specific requirements, while maintaining the principles of interconnection, functioning and interaction between them in the multifunction combat unit 26 and the grenade 1 as a whole.

The invention can be implemented in defense plants producing shards, cumulative, cumulative shards and other ammunition, with investments only required for tooling and equipment for the production of original parts and assembled units. Generally new technologies and materials are not needed.
