Description

The invention relates to the field of combat use of artillery and can be used to deliver a video camera with a GPS / GLONASS system using an MLRS rocket, as well as shells (min) of other artillery systems of a caliber of 82 mm or higher, in the area where possible targets are located to detect, shooting, adjusting and evaluating the results of artillery fire from closed firing positions.

A known method of target shooting using a rangefinder [1]. The range finder determines and reports the range and directional angle in the center (specified point) of the target, and during the shooting - for each gap.

Deviations of discontinuities in range determine how the difference between the distances to discontinuities and the target measured by the range finder. Deviations of discontinuities in the direction are calculated as the difference in directional angles for discontinuities and goals or measured using another optical device (compasses, binoculars, etc.).

The disadvantage of this method is that the target shooting is possible only if there is a direct line of sight of the target using a rangefinder and compass (binoculars).

A known method of shooting targets using a stopwatch [1].

Zeroing with a stopwatch is used to shoot at targets that reveal themselves with brilliance and the sound of shots. To determine the distance from the observation point to the sounding target, four counts are taken from the stopwatch from the moment of observing the brilliance of the shot (starting the stopwatch) to the moment the sound of the shot arrives (stopping the stopwatch).

The average countdown of the stopwatch (accurate to 0.1 s) is multiplied by 1000, divided by 3 and get the range in meters. To determine the deviation of the breaks from the target in range in meters from the obtained stopwatch count (the average count for the group of breaks), the average stopwatch count for the target is subtracted, the found difference is multiplied by 1000 and divided by 3.

The direction to the target from the observation point is determined using the oriented optical device as the average value of the directional angles (counts) by the brightness of the shots. The disadvantage of this method is that the target is possible only in the presence of direct visibility of the target and the brilliance of the explosions of the shells.

A known method of shooting targets using units of sound reconnaissance [1]. The sound reconnaissance unit determines the deviation of the gap (center of the group of discontinuities) from the target in range in meters and in the direction in the divisions of the goniometer for the firing position using the sound reconnaissance device. The sighting begins with a single shot.

In the report of the commander of the sound reconnaissance unit, “The gap is not detected”, the shot is repeated after checking the installations for firing, pointing the guns and checking the equipment of the sound reconnaissance equipment. Based on the received deviations of the gap, corrections are introduced and a battery queue is assigned.

The disadvantage of this method is that the rupture of the projectile may not be detected and additional time is required for conducting sound reconnaissance. To maintain a sound reconnaissance station, a specialist unit is needed.

A known method of target shooting using a radar station [1]. The sighting begins with a single shot of the main gun. Having received the report “There is a target” from the station manager, a second shot is fired at the same facilities. If the projectile is not detected (report of the head of the station “No target”), the shot is repeated after checking the settings for firing, pointing the gun and the radar station. In the report of the head of the station, “The goal is lost”, a second shot is fired after a report on the readiness of the station for notching.

Having received from the station manager the deviations of the average point of incidence of two shells from the target in range in meters and in the direction in the divisions of the protractor for the firing position, their signs are changed, the corrections obtained are entered and the shooting proceeds to fire.

The disadvantage of this method is that the rupture of the projectile may not be detected and additional time is required to prepare the radar station and artillery guns before re-firing. To maintain a radar station, a specialist unit is needed.

A known method of shooting targets for observing the signs of the gap [1].

The sighting begins with a single shot on the counted installations. If only the lateral deviation of the gap is measured in the first shot, the gap is brought to the line of observation, assuming a deviation in range of zero. Having received the sign, they take the gap in transit (non-flying) along the observation line by the size of the first fork, equal to 200 m, introduce corrections taking into account the measured deviation of the gap in the direction and designate the next shot. Depending on the deviation of the gap from the target in range, the size of the first fork can be reduced or increased. This is done until a gap of the opposite sign is obtained.

After that, corrections are introduced, taking the deviation of the gap along the line of observation two times smaller than the accepted previous deviation, and, if necessary, continue shooting.

The disadvantage of this method is that the breakpoints can only be determined within their line of sight from the firing positions of the battery (division).

There is also known a method of target shooting using a helicopter [1].

Targeting using a helicopter is carried out according to the measured deviations using instruments installed on the helicopter or a scale. The sighting is carried out in volleys of batteries (platoons) with a concentrated fan. The navigator-spotter determines and reports the deviations of the center of the volley (gap) from the target: during sighting according to the measured deviations along the axes of rectangular

coordinates in meters; when shooting with a scale - in range and direction in meters. The advantage of this method is the ability to observe the target and the points of the shells rupture from a height, while natural interference on the earth's surface does not affect the results of the shooting adjustment.

The disadvantages of this method are the need to use a helicopter to adjust artillery fire; helicopter landing pad should be located relatively close to the firing positions to ensure shooting mobility, which is not always possible in combat conditions; the task of adjusting fire is fraught with danger to the life of helicopter pilots, since the helicopter can be subjected to a missile attack from the enemy; high cost of target shooting in this way.

The closest in technical essence to the proposed invention is the invention (prototype), patent No. RU 2642554 "Method of target shooting using a quadrocopter" [2].

The specified technical problem in this invention is achieved by the use of a quadrocopter with a video camera and a control panel with a tablet, which provides increased accuracy of target shooting without the use of optical measuring instruments, sound and radar stations with minimal projectile consumption in the absence of direct line of sight of the target and break points from firing positions (command observation point) due to the presence of natural disturbances for observation, as well as reducing the risk to the life of a spotter fire in ditions enemy countermeasures and cost reduction zeroing target.

A similar method of target shooting using a remotely piloted aircraft is described in the "Rules of shooting and fire control artillery. Division, battery, platoon, gun ”(PSiUO-11). Part I. - Moscow: Military Publishing, 2011 - p. 50 - 51. [1]. The basic equipment of the UAV allows you to determine the rectangular coordinates of the center of the discontinuity group (CGR), the deviations of the CGR from the target along the coordinate axes, as well as the polar coordinates

the goal (gap) relative to the position of the ground-based remote control point (NPDU).

To simplify shooting (fire adjustment) using UAVs, it is recommended to use the rectangular coordinates of the target (gaps). The calculation is made using a computer, microcalculator or fire control device (PUO), as the difference of topographic data determined by purpose (gap).

In the event that the target is detected by other means, and the correction of fire on it is carried out with the help of UAVs, it is recommended to carry out additional reconnaissance (notching) of the target with the help of UAVs serving the shooting.

In this case, the accuracy of the sighting will be higher due to the compensation of the systematic error of the target notch (gap) using the UAV.

The disadvantages of this method are:

- significant time costs associated with the flight of the UAV to the area of the alleged location of the target;

- the length of time in the air from take-off to arrival in a given area, significantly increases its vulnerability in conditions of active operation of enemy electronic warfare and air defense systems.

A device (prototype) is known - a PC 9M534 shell with a warhead with reconnaissance unmanned aerial vehicle, designed for operational reconnaissance and target shooting [3,4].

The disadvantages of this device include:

- is the high cost of UAVs with deployed reconnaissance, target designation and fire adjustment equipment;

- significant risks associated with the detection and defeat of UAVs;

- UAV delivery with deployed reconnaissance, target designation and fire adjustment equipment is possible only in this case using rockets of the PC 9M534 type, 300 mm caliber;

The problem to which the invention is directed is to eliminate the disadvantages of these prototypes.

The technical result of the invention is to increase the efficiency of target reconnaissance and artillery firing maintenance using a multiple rocket launcher, as well as shells (mines) of other artillery systems of caliber 82 mm and higher by reducing the delivery time of a video camera with the function of transmitting optical-electronic load information in real time time for the command and observation post (KNP), the fire control unit of the division (PUOD); increasing the autonomy and independence of the functioning of the reconnaissance and fire complex (ROC) based on MLRS and other artillery systems without using other support units, as well as reducing material costs and risks associated with the detection and destruction of UAVs.

To implement the proposed method, it is possible to use standard lighting ammunition (82 mm mines C843, 120 mm mines 3C9, shells 122 mm C463 and 152 mm C6) with a slight upgrade, which consists in placing the camera unit instead of a torch.

The problem is solved by the proposed method and device.

The proposed method (Fig. 1) is that using a rocket projectile (1), a video camera unit with a GPS / GLONASS system is delivered to the affected area, the camera is parachuted and reduced and stabilized (2) with subsequent readiness for sighting and maintenance shooting to kill, as well as transmitting information about the location of the target, the results of firing at KNP (PUOD) in real time. Targeting of the target begins (from the moment the video camera is ready for shooting service) on the calculated installations of the sight, followed by the firing of a smoke projectile (3).

The operator, having received a video image with the burst point (4) of the smoke projectile on the monitor, determines its gap by the resulting smoke cloud, determines the coordinates of the burst place and transmits the coordinates to KNI (PUOD) (5). Based on the received coordinates of the gap, the corrections are calculated according to the general rules and proceed to shooting to kill. Target reconnaissance and firing support for MLRS are carried out by periodic monitoring

using rockets with a camcorder unit with a GPS / GLONASS system (figure 2).

The proposed device, in this embodiment, is a missile containing a remote fuse (1), a head unit with a video camera unit with a GPS / GLONASS system (2) and a standard parachute system (3), a solid fuel rocket engine (4) ) and the stabilizer block (5). The device is illustrated by a figure (2), which shows a missile with a camcorder unit with a GPS / GLONASS system in section.

The device operates as follows.

After a shot at a given distance, a remote fuse (1) fires, which ignites the expelling charge. The gases formed during the combustion of the expelling charge create the pressure necessary to release and subsequently eject the camcorder unit with the GPS / GLONASS system (2) and the parachute system (3).

Under the influence of high-speed air pressure, the parachute opens, the camcorder unit with the GPS / GLONASS system decreases at a speed of 8.5-10 m / s and provides an overview of the terrain with subsequent readiness for shooting and shooting service, as well as transmitting information about the target’s location, results firing at KNP (PUOD) in real time.
