HAZARDOUS ELEMENT OF CLASS AMMUNITION.

Poleanaya model relates to ammunition, and more to the end. to. cassette, whose shell contains many individual damaging elements - and, of course, fragmentation-cumulative effects.

The state of the art of the art is characterized by a striking element of cluster munitions, containing a casing filled with explosives, a cumulative recess in front of which an open cylindrical bushing is mounted on the casing, a tape stabilizer placed on the fuse and connected with it with a pin axis, and means for crushing the casing into fragments ( see Wehr Lehri ik N2, 1995, p. 41, Fig. C).

A drawback of the irrelevant element is that when used. | {E1 aluminum sleeve. providing a cumulative charge action at the most effective distance from the target’s surface, the reserve of static stability on the path of autonomous flight is not guaranteed for 1 reason for the displacement of the center of mass of the striking element to the tail.

When the stabilizer is forcedly short, the length of the KOTOpoio oipa is limited by the free volume between the fuse body and the open cylindrical sleeve of the superiorly striking element in the assembly of the cluster munition, the longitudinal stability of the striking elements is not ensured during autonomous flight and, therefore, is normal to the 1 rd orientation of the cumulative.

In addition to TO1O, the tape stabilizer folded in half and fixed at both ends on the transverse axis of the body shank can break off from the jerk during aerodynamic opening of the protector.

Activities of Oronrooy

The characteristics of the combat purpose are not satisfactory because of the low efficiency of the cumulative jet UO, because the focus of the cumulative recess is far behind the highlander of the 1 sleeve, since its length is minimized by the value of the overturning moment when the air flow rises and, secondly, restrictions on the area of destruction by fragments of a cylindrical-shaped body, which creates small angles of expansion of fragments and a low declination of fragmentation zero.

The noted drawbacks are eliminated in the striking element of the Hoio Boenricas cartridges io patent RU 2137087. F 42В 12/58, 1999i., Selected but technical essence and matching 1 signs as the closest to the analogue proposed.

The known damaging element comprises a housing having, on the outer surface 11, a means of crushing into fragments in the form of annular protrusions formed by a series of transverse grooves, and a bottom part in the form of a truncated cone, filling an explosive with a cumulative recess, 1de a conjunctive funnel is installed, in front of which a cylindrical funnel is mounted a sleeve with a collar inside on the open end, and a tape aerodynamic stabilizer folded in a zigzag, connected to the prick by a kinematically connected that skooy and ioierechnoy axis. mounted with the possibility of rotation and longitudinal movement relative to the fuse, equipped with a detonator capsule.

The execution of the bottom part of the conical shape with annular protrusions on the eio cylindrical part forming the protrusions of the iiojiy1 FROM fragments is set to RODOLNO1O crushing, 1ОVVozticheskaya stability of the damaging element.

Substitution in front of the corius of an elongated cylindrical structure ... and from le1chcho1o material (aluminum alloy alloy) -. Along with an increase in the area of the fragmentation zero, it contributes to an increase in the efficiency of the c.um.ul 1TIBNO1O funnel action, the focal length of which practically coincides with the end face of the striking element.

The connection of the tape stabilizer with the transverse axis of the fuse case by means of a rotary curved bracket deformed in operation increased the reliability of the product by damping the force of dynamic opening of the tape from zigzag, which made it possible to fix the tape at one end, thereby increasing the length of the aerodynamic stabilizer and, therefore, shift the center of pressure to the tail of the striking element, than to increase eio longitudinal stability on the path of autonomous flight

The stock of longitudinal stability during aerodynamic stabilization of the striking element created the prerequisites for increasing the length of 1 tin sleeve to the focal length of the cumulative funnel.

The spatially curved shape of the mount bracket tape on the stabilizer provides compact styling by turning around the 1 transverse axis on the fuse case.

The tape from zi1za1a is automatically opened on the trajectory of the flight of the attacking element by the incoming air flow without overlapping, loops and twisting, over the entire length of the stabilizer.

However, the disadvantage of the design of the well-known striking element is the low functional reliability and basic characteristics of the destination, that is, unsatisfactory combat action, both fragmentation and cumulative.

5 .

metal losses into small fragments and the formation of oojiee large parts than the fragments required for the mass and shape, which reduces the damaging fragmentation effect of the element.

The length of the hull, limited by the design of the airborne combat unit and the layout of the damaging elements in the Heio, does not allow the use of an elongated cumulative funnel more effective in armor penetration.

The kinematic connection of the tip of the stinger with the swivel bracket protruding beyond the dimensions of the fuse provides eio cocking by a belt aerodynamic stabilizer on autonomous flight, but does not guarantee safety in official handling, careless actions during which can cause unauthorized cocking of the fuse and operation of the striking element, for example, from accidental application of force to tape or when eio falls on a cluster munition assembly. which is unacceptable.

The task to which the present invention is directed is to increase the functional reliability and combat power of the striking element of the ammunition cluster, that is, I have been assigned eio basic X a ra K1 e r and t t and to.

The required technical result is achieved in that in a known striking element of a cluster munition containing a body having crushing means for fragments in the form of annular protrusions and a bottom part in the form of a truncated cone, filling an explosive substance with a cumulative recess, 1 there is a concurrent funnel in front of which is mounted on the body. A cylindrical sleeve with a shoulder inside on the open end, and a folded belt-mounted aerodynamic stabilizer connected to the pruning tip by by means of kinematically connected isoA staples and 1 transverse axis mounted with the possibility of rotation and longitudinal movement relative to the explosion b io /

For example, it is based on a detonator capsule, but at the suggestion of the authors, the annular protrusions of the body are equipped with radial or inclined flutes, and the cumulative recess with an adjacent funnel is profiled in the shape of an ulally 11O paraboloid, while the detonator capsule is mounted in a spring-loaded gate mounted a stopper, and a number of squashed slots are made in the sleeve, moreover, the ai1a1 belt-and-aerodynamic stabilizer is laid on a curly support placed on the fuse and closed by a cap equipped with an elastic fJ ance, and that zigz g lentochnsio aerodynamic stabilizer is placed in a polymeric bag.

Distinctive features ensured the solution of the task to increase the functional reliability and ooeBoio MOI of the destruction of elements of cluster munitions.

An additional longitudinal or inclined riffle on the annular protrusions of the body formed a grid of equally distributed semi-finished fragments of a given crushing, optimal in shape and mass, which increased the fragmentation of the striking element and increased the length of the body eio without increasing mass, and the center of mass of the product as a whole shifted forward, further increasing longitudinal stability on the path of autonomous flight to the target.

At the same time, it became possible to place an elongated long-focusing cumulative funnel in the form of an elliptically paraboloid in the body that is more effective in armor penetration, the maximum effect of which is ensured by a guaranteed orientation of the striking element about normal to the pretrad.

P r e r N i n c h i r s t e r p o r h y It prevents the unauthorized actuation (cocking) of the fuse in official handling, geometrically locking in the inoperative position (offset from the tip) the spring loaded gate carrying the detonator capsule. The fuse can be cocked only when the striking elements are ejected from the Goeiip Hiiaca cassette, after the ci-oranin and the technical composition of the stopper are ignited by an external temperature pulse when the charge of the common cassette is transmitted, which is transmitted through the through slots of the i-sleeve, which is charged with the tail but the axis is striking Io element.

Through the slots in the 1-cylinder cylindrical sleeve, ignite the ignition and technical composition of the stopper of all damaging elements of the cartridge rip1 from the external temperature and pressure impulse generated by the action of the inside of the shell being expelled about the charge into the cut. In this case, the detonator capsule is automatically fed by a spring-loaded gate. This removes the protection level in official use. and the inertial fuse is ready for operation,

Consequently, each essential feature is necessary and their combination in a stable relationship is sufficient to achieve the novelty of quality and the form of affect of the amount, which is inherent to the 1 signs of disunity.

The invention is illustrated in the drawing, id are shown: on phi1-, 1 - proposed damaging element; on fi1.2 - fuse safety device; in Fig.Z - striking element in autonomous flight.

In the recess of the filling 1 of the explosive substance of the body 2, strikingly Io: the conjunctive cumulative funnel 3 {phi1 is mounted on the element. 1). made in particular in the form of an elliptical AO paraboloid. Due to the parabolic configuration elongated, compared with the conical in the prototype, by 15% of the funnel 3 in the explosive filling 1 of the casing 2, a greater velocity gradient is provided in the initial part of the shaped-charge jet, which increases armor penetration by about 30%.

On the outer surface of Kopiiycci 2, annular and longitudinal corrugations 4 and 5, respectively, are made., Which form a grid of equally distributed 1-cell fragments 6 of a given 1 eio-fragmentation.

Formed by intersecting riffles 4. The 5th grid of 1-cell fragments G provides redistribution of the mass element of the body to the 1-part of the ior..ashes1 of the body 2. The length of KOTopoio increases by about 7% by the increase in eio mass, while the open end fixed to the body 2 is cyan. 1 bushings 7 is located at the focal length of a longer cumulative funnel 3. having the shape of an alli Tic1O paraboloid.

The bottom part of the body 2 is made in the shape of a truncated 1O cone and is associated with a smaller fuse 8. On the transverse longitudinally movable axis 9 of which a rotary, curved bracket 10 is mounted.

The tape 11 of the LTKP-25-200 brand (GOST 176G7-77) with a width of 25 mm and a length of 1 m is folded in a zigzag and placed in a plastic bag 12. which is laid on a specially profiled support 13 mounted on the fuse case 8.

When storing and transporting the striking element, its tail section is closed by a safety cap 14. which is pressed against the support 13 and is fixed on the fuse case 8 by a screw 15. located inside the axis 9 (fi1.2), preventing arbitrary opening of the tape 11. The cap 14 is equipped conical flange 16. which performs the functions of a leaf spring during the axial matching of the damaging elements in a cluster munition.

Before assembling the cluster munition, the screw 15 on the cap 14 of the rear part of the striking elements is removed.

Horo element, with a colink 14 paciiojiaiaeTCH nal with its circular outline 17, made inside but outside. When the damaging elements are axially joined for assembly into the cassette, the shank of the lower damaging element Io is fed into the sleeve 7 of the upper one, and the thin-walled conical flange 16 of the cap 14 of the lower Heio of the damaging element, elastically deforming on the smaller diameter of the collar 17, is fed aa Heio, 1de and is installed, geometrically locked to shoulder 17.

Thus, the annular flange 17 as the stiffening ribs of the open cylindrical sleeve 7 performs the functions of an abutment and a stripper of the cap 14 when separating the joined striking elements ejected from the cassette of the cassette.

In the sleeve 7, a series of through radial slots IS is made for communication with a safety device of a superiorly reflective element in the assembly of the cartridge cassette: with an irrotechnical stopper 19 (Fig. 2) of the gate 20. carrying the detonator capsule 21 of the fuse 8 and loaded with a spring 22. Inner fuse 23 8 is placed in the hole 24 of the gate 20.

A container 25 with a detonation transfer charge 26 is fixed under the gate 20.

Before the striking elements are ejected inside the cluster munition, a pyrotechnic charge is triggered and a pressure of 10.012.5 atm and a temperature of 600-700 ° C are created, which through the through slots 18 of the bushings 7 ignite the pyrotechnic composition of the stopper 19 located inside of the striking element, which is internally aligned along the axis.

After the cluster munition is ejected from the shell, the striking elements are undocked for separate autonomous movement to the target without a cap 14, which remains inside the single-cylinder cylindrical sleeve 7 located in the cartridge of the striking element, on the abutment of its annular shoulder 17.

With a free-flowing air stream, the packet 12 collapses from the rear of the folded belt ii, which opens, the aerodynamic stabilizer. and scooa 10. unbending. damps the braking force from the opening of the tape 11 jerkily, and occupies an axial position relative to the housing 2 (Fig.Z). In this case, the inertial sting 23 moves relative to the housing 2 to its highest position, freeing the opening 24 of the gate 20.

Further, when C1 is the pyrotechnic composition of the stopper 19, the gate 20. is released, which, under the action of a compressed spring 22, moves the detonator capsule 21 under the tip 23 - the fuse 8 is cocked.

The tape 11, which opened behind the shank of the striking element, displaces the center a:) of the dynamic pressure backward, providing longitudinal stabilization of the striking: element on the path of the Hoio autonomous flight and its almost vertical position when meeting the obstacle, which is necessary for reliable operation of the inertial fuse S and the effective action of the cumulative jet.

When encountering an obstacle, the sting 23 inertially progressively moves downward and punctures the stationary detonator capsule 21, the impulse of action of KOTOpoio initiates the detonation charge 26 of filling 1 of the housing 2. In this case, KOJUiaK 14 jumps out of sleeve 7 with a jump in the pressure of explosion of filling 1.

When filling 1 is deactivated, funnel 3 collapses with the formation of a cumulative jet, and the element body 2 is torn along the sections weakened by intersecting corrugations 4 and 5 into fragments 6 given in shape and mass, affecting the enemy’s manpower.

In this way, the well-known ammunition has been structurally improved to increase the combat power: the effectiveness of armor penetration and fragmentation of the action of the striking elements, with complete safety in official use.

A comparative analysis of the proposed technical solution with identified analogues of the prior art, from which the invention does not explicitly follow for ammunition, stated that it is not known, but taking into account the suitability of the striking element for implementation in serial production, we can conclude meeting the criteria of 1 atentos 1 features.
