Description

The proposed utility model relates to artillery armament ammunition, namely to shells, artillery mortar shells having both axial and circular destruction fields. Can be used to destroy lightly armored vehicles.

Known fragmentation-beam projectile "PERUN" RU 2237231 from 27.09.2004, containing a housing with an explosive charge (explosive), a fragmentation unit located in front of the explosive charge, and a head fuse of the trajectory-contact type.

However, in this device, the design drawbacks include a large value of the angle of expansion of the elements (the half opening angle is up to 45 °

In addition, known ammunition "TVERICH" RU 2346230 dated 02/10/2009, RU 2705134 dated 02/14/2019, which is a prototype of a useful model. The projectile contains a body with a leading belt and an explosive charge in the bottom, containing a head cap and ready-made striking elements that form a block.

However, in the specified device, the disadvantage is the unsatisfactory performance of penetration by compact submunitions.

The task (technical result) of the proposed utility model is to increase the penetration rates by ready-made striking elements.

The task is achieved by the fact that the ammunition with ready-made striking elements contains a body with a leading belt and an explosive charge in the bottom part containing a head cap, under which the finished striking elements form a block. The striking elements have an arrow-shaped shape, which has a positive effect on the penetration depth, since when the striking elements are lengthened, the path of the shock wave and the expansion wave when hitting an obstacle increases, as a result of which the time of impact of the striking element on the obstacle increases in comparison with a compact striking element of the same mass and having the same same speed. In addition, the striking elements have a hexagonal profile that allows you to tightly lay the striking elements, leaning on the edges of each other, in the cylindrical part of the body with the leading belt between the discarded fairing and the wad, which rests against the thickening of the cylindrical part of the body. An expelling pyrotechnic charge is located under the fairing. A radio fuse is screwed into the fairing, which is connected by a fire conduit to a primer-igniter designed to ignite an expelling pyrotechnic charge. The igniter capsule is connected through a wad by a fire conduit with a retarder, which in turn is connected to a detonator capsule designed to initiate an explosive charge.

The drawing shows a longitudinal section of the proposed ammunition, which shows: Radio fuse 1, head cap 2, fire conduit 3, expelling pyrotechnic charge 4, primer-igniter 5, block of ready-made arrow-shaped striking elements with a hexagonal profile 6, wad 7, retarder 8, detonator cap 9, explosive charge 10, housing 11, leading belt 12.

The proposed device looks like this. The head part of the ammunition contains a radio fuse 1, which is screwed into the head cap 2, the radio fuse is connected to the fire conduit 3. Around the fire conduit 3 by the head cap 2 there is an expelling pyrotechnic charge 4, at the end of which there is a primer-igniter 5, the primer-igniter 5 is connected to fire conduit 3. Following the expelling pyrotechnic charge 4 is a block of ready-made arrow-shaped striking elements with a hexagonal profile 6, which rests on the wad 7, the fire pipe 3 passes through the wad 7, connected to the moderator 8, the moderator 8 is connected to the detonator cap 9, which is located in the explosive charge 10. The wad 7 also rests on a thickening in the cylindrical part of the body 11. In the body 11 there is a leading belt 12.

The utility model works as follows: at the moment of firing, the wad 7 rests on a thickening in the cylindrical part of the body 11, thereby preventing the contents of the projectile from displacing under the action of inertial forces. At the same moment, the leading belt 12 is cut into the grooves in the barrel bore, as a result of which, after the shot, the projectile rotates along the longitudinal axis. At the moment of approaching the target, a radio fuse 1 is triggered, which transmits a signal through a fire conduit 3 to a primer-igniter 5, which ignites an expelling pyrotechnic charge 4, due to the combustion of which it tears off the head cap 2, at this time the signal is transmitted by means of a flame conduit 3 to the moderator 8 and after breakdown and departure of the discharged fairing 2 from the projectile trajectory, the retarder 8 transmits a signal to the detonator cap 9, which initiates the charge of the explosive 10. Due to the detonation of which, the wad 7 is thrown, a block of ready-made arrow-shaped striking elements having a hexagonal profile 6, which creates an axial fragmentation field also there is a crushing of the housing 11 creating a circular fragmentation field. Arrow-shaped striking elements having a hexagonal profile 6 are oriented in space due to the plumage, and shock waves appear in the striking elements and obstacle when they hit an obstacle. A shock wave passing along the entire length of a striking element having a hexagonal profile 6, is reflected from the free end in the form of an expansion wave, passes along the entire length of a striking element having a hexagonal profile 6 in the opposite direction, and catches up with the shock wave in the obstacle. Due to the increased path of waves, the impact time of a striking element having a hexagonal profile 6 on the obstacle is longer, and, consequently, the penetration depth is greater in comparison with a compact striking element of the same mass and having the same speed.

The technical result consists in increasing the penetration rates by ready-made striking elements, due to the use of arrow-shaped striking elements having a hexagonal profile.
