Description

The invention relates to the field of ammunition, in particular to the field of artillery shells used in the firing of artillery guns used in the counter-battery combat complex and designed to engage enemy receiver and rocket artillery units, as well as mortars at firing positions and firing.

Known devices for guided artillery shells (UAS), capable of hitting various targets, including artillery units located at firing positions and firing.

Such UAS include guided artillery shells "Krasnopol", "Krasnopol-M-1", "Krasnopol-M-2" [1], corrected artillery shells "Centimeter", "Centimeter-1M" [2], "Kitolov", “Kitolov-2”, “Kitolov-2M” [1], the adjusted mine “Daredevil” [3], guided mine “Gran” [1, 4] and also guided artillery shells of the complex “Coalition-SV” [5]. Complex 2S35 "Coalition-SV" - 152 mm self-propelled howitzer brigade level [6].

All of the listed ammunition (except for the UAS of the Coalition-SV complex) are equipped with passive homing heads that receive backlight signals reflected from the target by a laser target designator-rangefinder. The illumination is carried out by the observer-operator in front, who determines the type of target and its importance, sees and evaluates the results of combat work. Thus, selective destruction of targets is carried out, including in settlements in the presence of civilians, which is a positive quality of these ammunition.

The disadvantages of this type of ammunition are:

- the need for the observer-operator with a laser target designator-range finder at a direct line of sight from the target;

- Failure to comply with the principle of "shot - forgot."

In addition, the listed ammunition (except for the UAS of the Coalition-SV complex) has a relatively small maximum firing range (26 km or less).

The Coalition-SV complex has a maximum firing range of 70 km [7] and is capable of firing with several variants of guided artillery shells.

The disadvantage of these shells is the ability to aim only at a given, previously explored target.

Elimination of this drawback is possible when using such shells in the counter-battery control complex. In such a complex, reconnaissance of targets is carried out by a radar station, which provides reconnaissance of firing enemy batteries.

To ensure the possibility of effective use as part of the counter-battery control system, it is proposed to make changes to the UAS device. In particular, it is proposed to equip the radio with guidance commands transmitted by the radar station of the reconnaissance of firing batteries from the ROC of counter-battery combat, and an antenna-feeder device (AFU) for receiving radio guidance commands having an antenna system. It is proposed that the AFU antennas be connected to the input of the radio receiver of the guidance commands and placed in recesses on the shell of the projectile in its tail part.

The radiation pattern of the AFU antenna system is directed to the rear hemisphere from the projectile.

These differences in the UAS device provide the ability to achieve a new technical result, which consists in aiming the projectile at a target detected using real-time radar reconnaissance, that is, without prior reconnaissance before firing.

The closest analogue (prototype) of the proposed device are UAS complex "Coalition-SV" [8], the device of which is shown in the drawing (Fig. 1). The UAS includes a housing - (1) with a cowl (2); inside the case, stabilizers (3) and aerodynamic rudders (4), which are opened after the projectile leaves the barrel, compartments containing a high-explosive fragmentation warhead (5), contact fuse (6), and the instrument compartment (7) are located in the folded state there are instruments of the inertial control system (8), a GLONASS / GPS satellite radio navigation system signal receiver (9), a computing device (14), a control command generation unit (15) supplied from the instrument compartment to the steering machines (16), which provide aerodynamic control them rudders (3). UAS has a solid fuel jet engine (17). The drawing also shows the nozzle of the engine (18) and the antenna of the receiver of the GLONASS / GPS system (10) (a possible arrangement of the antenna).

To ensure the applicability of this projectile for use in artillery guns operating as part of a counter-battery warfare complex, it is proposed that the on-board equipment of the projectile include a radio command control receiver (11) transmitted by a radio transmitter located on the radar of the reconnaissance battery of shooting batteries, an antenna-feeder device for receiving radio commands ( 12) with antennas (13) located in the recesses on the housing (1) in its rear part, connected to the input of the receiver (11). The placement of the antennas in the recesses on the housing in the rear of the projectile provides a more reliable reception of radio guidance commands compared to their placement in other places of the housing.

The proposed UAS device, when used by artillery units operating as part of the counter-battery combat complex, works as follows:

After the reconnaissance of enemy artillery units conducting fire using radar and determination of their coordinates (Zoo-1M type radar [9, 10]), a command is sent to the artillery unit operating in the complex from the command post of the complex to open fire controlled artillery shells on a proven target. After a shot on board the UAS, the radio of guidance commands (11) automatically turns on. When approaching the UAS to the target and detecting it using the radar at this station, the problem of calculating the expected coordinates of the UAS incidence point is solved, the corrections to the expected coordinates of the incidence point that need to be worked out by the time of the fall are calculated, and control signals proportional to the calculated corrections are generated. On the radar, a radio transmitter is turned on, transmitting the UAS guidance commands to the explored target, generated by the control signals. On the UAS, radio guidance commands are received using antennas (13) of the antenna-feeder device (12) and transmitted to the input of the radio command receiver (11), the output of which is connected to the input of the computing device (14), where, based on the radio commands, signals from the inertial control system ( 8) and signals from the receiver of the GLONASS / GPS system (9), signals are generated that enter the control command generation unit (15). Next, control commands are given to steering machines (16), which drive the aerodynamic wheels (4), providing guidance of the projectile to the explored target. Thus, high-precision guidance of the UAE on the target is carried out.

Thanks to new features, the proposed device allows to obtain the claimed technical result: the defeat of the target without its preliminary reconnaissance.

The advantages achieved by using the proposed device are as follows:

- there is no need to have an observer-operator with a laser target designator-range finder located at a direct line of sight to the target;

- the principle of "shot-forgot"

- provides high accuracy guidance UAS to explored targets.

The creation of the proposed device is preferably based on the UAS [8] of the Coalition-SV complex, since the maximum firing range of these shells is close to the maximum range of reconnaissance of firing positions with a shot using a Zoo-1M radar.
