The primer detonator is positioned in the breech of the coned mortar. EFFECT: enhanced efficiency of fighting against low-flying missiles. 4 cl, 2 dwg

Description

 The invention relates to air defense of individual military and industrial facilities and, in particular, to local means of destruction of low-flying long-range missiles.

 Low-flying long-range missiles received military use only in recent years. These include the American Tomahawk cruise missiles (445 kg warhead, range 1,600 km) and AGM 86 (900 kg warhead, 2,500 km range), used in the bombing of Iraq, Yugoslavia and Afghanistan.

 These missiles fly at an extremely low altitude (100 - 150 m), and their defeat presents certain difficulties, which, with regard to local air defense forces, can be solved using the present invention.

 The prototypes of the invention are: according to the method - application DE 3536328, F 41 H 11/02, 05/31/1990, on the device - patent of Russia 2087840.

 However, these methods are ineffective and at the same time expensive to deal with low-flying objects.

 In prototypes, the problem is solved either using the homing system of an explosive device, or using a special aircraft equipped with rocket engines, an orientation system, mortars, and other expensive and complex devices.

 The task is to create such a method and device for hitting low-flying missiles, which would ensure high reliability of the defeat at the minimum cost of their development. This is the technical result of the invention.

 A schematic diagram of a method for hitting low-flying missiles is shown in FIG. 1.

 A diagram of a device for hitting low-flying missiles is shown in FIG. 2.

 The essence of the invention lies in the fact that to protect local military and industrial facilities in missile-hazardous areas, they establish complete exclusion zones 3, which are equipped with mortars 4, through which they create a cloud of crushed stone fragments on the rocket path to disable its aerodynamic rudders and laser heads guidance.

 Mortars 4 using a powder charge throw a cloud of gravel to a height of 100 - 150 m, damaging the aerodynamic rudders and laser heads of missile guidance on the target.

 Mortar control is carried out from the control hopper 5 by the commands of surveillance and air defense warning systems via electric cable network 6.

The crushed stone cloud contains about 200 thousand fragments of granular (3-5 cm ³ ) crushed stone; in the space at a height of 100 - 150 m it creates a fence zone with a width of about 600 m.

 The falling of fragments to the earth occurs only within the zone of complete alienation.

 A shot from the mortar is carried out for 0.5 - 1.5 s (on command from the control hopper) until the rocket crosses the front edge of the zone of complete exclusion.

 The stock of granular gravel is in dump 7, from which it is transported by dump trucks 8 to the mortars along highway 9, and layered zones of complete exclusion are arranged around the mortars.

The missile destruction device has a conical mortar 10 with an opening angle of 35 - 45 ^o , while it is configured to automatically open its covers 16, and also with the possibility of filling it with granular up to 3-5 cm ³ gravel 17 in the amount of 1000 - 1500 kg and installation into it under the rubble of the obturating wad 15 and powder charge weighing up to 20 kg, while the detonator capsule 14 is placed in the breech of the conical mortar.

 The device uses an automated loading system for crushed stone, conveyors and an automated system for supplying ship-type powder charges.

 Mortira is a metal conical structure 10, mounted on a powerful bed 11.

 In the lower part of the cone there is a breech 12 with a bolt 13 and a detonator capsule 14. A powder charge 15 weighing up to 20 kg is introduced into the mortar through the breech. Above the powder charge is placed obturating wad 15, made of non-combustible material. On top of the mortar is closed automatically opening lid 16.

Granular crushed stone 17 in the amount of 1200 kg is placed above the wad 15. The opening angle of the cone is 45 ^o , which provides a wide capture of the target at a height of 100-150 m

 The implementation of the method of protection against low-flying missiles is as follows. Upon the onset of combat readiness, all services and mortars are put into combat position. Upon receipt of information from the air defense early warning means, the control bunker gives a command to open the covers of the corresponding mortars and makes a ballistic calculation of the moment of their detonation. Undermining is carried out for 0.5 - 1.5 s until the moment the rocket crosses the leading edge of the exclusion zone. After this, the mortar is reloaded for the next detonation.

Calculations show that only with an opening angle of the mortar equal to 35-45 ^o , it is possible to reliably ensure the capture of the target with a width of the capture zone of about 600 m.

The optimal granule size of crushed stone is 4 cm ³ , which provides the destructive force sufficient to hit a rocket at a speed of meeting with a rocket of the order of 500-600 km / h.

 The distribution density of crushed stone fragments in space provides an average distance between fragments equal to 15-20 cm, which is quite enough to destroy a rocket that has fallen into such a cloud of crushed stone.
