Definitions

the invention relates to munitions with a warhead having a shell with cuts to provide for its uniform fragmentation or containing multiple individual killing elements and is useful in self-defending a vehicle, preferably a tank.
Density of bullet shower of the prototype is not enough to hit warhead or fuze incorporated in a small-sized munition such as antitank missiles due to a great dispersion sector of bullets associated with a spherical shape of the bullet-forming lining. Additionally, the prototype munition is intended to be activated on the ground or water surface and requires sophisticated development work to mount vehicles mainly due to powerful detonation blast effect on the bearing surface.
the explosive charge of ejected defensive round is configured as a rectangular biconcave lens with its face side covered by a bullet-forming lining and its rear side housing a fuze connected by a wire communication line to the detonation control system.
This configuration of the charge ensures narrowing the dispersion sector of the bullet-forming elements and uniforming their distribution density within the given sector because every lining element ejected by the adjacent explosive charge layer has an inclination to the round's axis determined by slope of the cone walls (shaping) and the recess, opposite the lining, reduces pressure of explosion gases on the bullet-forming lining elements located nearer to the centre of dispersion sector.
Velocity decrease of central elements thus obtained results in an ordered (of equal density and flat) array of bullets enhancing probability of target engagement in the predicted space point.
the rectangular (in plan) lining ensures practical incorporation to box-shaped munitions of narrow-directed action.
the bullet-forming lining is an arrangement of intersecting cuts building thin plates fastened together and of pyramidal shape to ensure the bullet-forming effect during fragmentation of the lining elements at munition detonation whereas they change their shape and roll up to bullets because of greater acceleration received by plate material located round the periphery of the pyramid base as compared to its central portion.
This is an optimum technical approach to take off explosion power by means of a thin flat plate during ejection and the following flight in a now compact size and with small ballistic coefficient.
a shape of the bullet-forming plate ensures more ordered distribution of bullets in the destructive array due to a better lining fragmentation to bullets during throwing.
the process of bullet formation shall also be dependent on the ratio of the maximum plate thickness to an average value within a range of between 2.2 and 3 as well as on that of an average thickness value to the side length of the pyramid base within a range of between 0.1 and 0.3.
Material of the bullet-forming plate must be of good ductility at a given strength in order to form non-destructive compact bullets during detonation.
the bullet-forming lining is configured with a thickness enhancing towards the bottom of the defensive round.
the body of the defensive round has a longitudinal guiding groove with its depth decreasing towards bottom, said groove takes tapered plate with spikes on its surface which makes contact with the internal surface of the barrel, presses the round to the barrel wall during firing and eliminates round's vibrations in the barrel during the movement because of taking up gaps between barrel wall and round, this being of particular importance for artillery systems with rectangular cross-section of the bore that is difficult to be manufactured to accuracy required.
the plate carries spikes which can engage in the less hard lining of the interior barrel space or are able to deform at specific greater pressing forces.
the cartridge case with explosive charge and ignition means has along all of its length gas vents directed towards the defensive round whereas the cartridge case is situated perpendicular to the ejection line.
This design ensures stable powder burning at low pressures in the space behind the round and reduces maximum pressure inside the barrel.
the cartridge case and its vents' orientation allows to decrease losses in energy of working propellant powder charge used to turn gas streams towards the barrel exit.
the wire communication line of the munition providing its connection to the detonation control system is built as a microcable and laid as a flat knitted band secured on the body of the defensive round, said wire communication line ensures compact placement and positive operation of the wire under acceleration forces and exhaust actions when travelling inside and outside the barrel because of damping the untwisting wire interlacing (e.g. flat knitting).
the munition is provided with a disposable steel barrel-container with its inner surfaces lined by a plastic to ensure high precision of the bore without machining a high-strength material.
Fig.1, 2 are front and side views (longitudinal axial sections) and Fig.3 shows a top view of the munition provided.
Fig.4 is the munition in its longitudinal section through an installation place of the tapered plate.
Fig. 5 shows a top view (seen from the face) of the section of dispersion sector of bullet-forming lining elements of the flat explosive charge with two recesses.
Fig.6 shows the appearance of the bullet-forming lining seen from the cut side with variable thickness of bullet-forming 30 elements.
Fig.7 is a lateral sectional view of the bullet-forming lining.
Fig.8 illustrates working principle of the round with bullet-forming lining of variable thickness.
Fig.9,10 show the defensive round with wire communication line prior to and after unlaying the cable (ejection).
the munition includes a flat explosive charge 1 in form of rectangular biconcave lens, a plastic body of the round 2, a bullet-forming lining 3 of a rectangular funnel-type shape filled with foamed plastic 4, a fuze 5 , a case 6 with gas vents 7, a propellant powder charge 8, an electric igniter 9 as an initiation means, a wire communication line 10 to conduct electric pulses, an external connector 11 to couple to cables 26 of the ejection and detonation control system, a barrel-container 12 made of sheet high-strength maraging steel with bands 13 and a bore shaped with plastic cover 14, tapered plates 16 fastened with studs 15 and with spikes 17 in grooves 21, set tails 18, and a protective cover 19 with explosive bolts 20.
the munition functions as follows: The electric pulse from the detonation control system, via the external connector 11 and wire communication line 10, enters the electric igniter 9 of the propellant powder charge 8.
the propellant charge burns within the constant space of the case 6 and effluent gases flow through the gas vents 7 towards the defensive round ejecting it out of the barrel-container 12.
the explosive bolts 20 which fasten the protective cover 19 to the muzzle band 13, break away.
the munition slides over the tapered plates 16 which press, with their spikes 17 being forced into the plastic barrel cover 14 and moving on the opposite tapered surface A (see Fig.4) in the body grooves 21, the round along the full length of its face side to the opposite surface B of the barrel-container.
the bullet array is propelled within a narrow sector W thus ensuring high probability of hitting the warhead of small-size attacking rounds because of forming in this sector a flat destructive front line with evenly distributed array of bullets (plane K in Fig.5).
This effect is produced by means of propelling the bullet-forming elements from inclined surfaces of the funnel-shaped bullet-forming lining 3 covering the front recess on the explosive charge (surface D in Fig.2,5) and due to influence of the rear recess on the charge (surface E) slowing the velocity of bullets in the sector centre.
the munition allows to effectively engage warheads of small and great diameters in close proximity to the defended object.
the plastic body of the defensive round, its stable flight and directed propelling of bullets within a narrow sector towards the ground ensure possibility for infantry to accompany tanks on the battlefield.
An ordered array of "rigidly" arranged distribution of killing elements (bullets) ensures improvements by a factor of 15 to 20 percent in kill probability of a threat weapon. Formation of bullet array with a linear distribution of velocity profile allows to reduce residual armour penetration of the targets engaged.
