Description

SUBSTANCE: invention relates to combat reactive technology, namely to a fire control system of a launcher (PU) of a multiple launch rocket system (MLRS) and is intended for aiming at a target and launching unguided rocket projectiles.

Known multi-barreled launcher machine (RU, invention according to patent No. 2213316, F41F 3/04, 1989), the fire control system of which incorporates a projectile launch circuit containing a switch, a pulse generator, a shift register and an ignition circuit for electric projectile igniters. The projectile launching circuit described in this utility model ensures that projectiles are fired sequentially in a predetermined number.

However, the well-known utility model has the following disadvantages: there is no control of the integrity of the start circuits; there is no control of docking with the electric fuse of the projectile and the presence of the projectile in the guide tube of the launcher, which does not allow determining the number of projectiles in the launcher with incomplete charging (loading); there is no possibility of displaying and outputting information about the state of the launcher, the process of launching shells and its completion.

As a prototype, the fire control system of the launcher of the combat vehicle of the multiple launch rocket system was chosen (“Product 634B. Combat vehicle of the TOS-1A system. Technical description. Part one”, Omsk, OJSC KBTM, 2009, p. 1, 11, 12 , 42-47, 82, 99, 100 and the brochure "Heavy flamethrower system TOS-1A", JSC Concern "Uralvagonzavod", p. 6), which contains power drives for pointing the launcher in the horizontal and vertical planes, sensors installations, observation devices, sighting devices, a ballistic computer unit with an indication unit, devices for launching rockets and an electrical installation kit of connecting cables.

Devices for ensuring the launch of rockets include a current distributor and a pulse block.

The current distributor is intended for programming the number of shots in a salvo and for controlling firing, distributing current pulses from a power source over electrical circuits in a certain sequence and checking the serviceability of these circuits and electric projectile igniters. The power distributor is made in the form of a metal case with a top panel and a cover. On the top panel there are parts, assemblies and electric radio elements of the current distributor. On its front side there are controls and indications. The power distributor is located in the habitable compartment of the combat vehicle in the operator's working area.

The block of impulses is designed to form current impulses with the specified parameters of the projectiles supplied to the electric igniters and to block the launch of the projectiles when the position of the launcher is inadmissible and is made in the form of a metal base closed with a lid. The base serves to install and fix on it all the parts and assemblies of the impulse block. The impulse block is located in the habitable compartment of the combat vehicle in front of the operator's workplace.

The disadvantages of the prototype include the following:

- lack of automatic monitoring of the integrity of the launch circuits and the presence of docking of rockets with the contacts of the guide tube of the launcher;

- lack of alarm and indication in case of projectile failure after the launch command;

- sequential supply of current pulses through the guide tubes, which increases the time until the first projectile comes off when the launcher is not fully charged:

- execution in the form of two separate blocks: a current distributor and a block of impulses, which requires the presence of additional cable assemblies in the wiring kit of cables, which complicate the wiring;

The technical result of the invention is to expand the functionality of the fire control system of the launcher of the multiple launch rocket system by increasing the information content and controlling the process of launching rockets.

The technical result is achieved by the fact that in the fire control system of the launcher of a multiple launch rocket system, containing power drives for pointing the launcher in the horizontal and vertical planes, position sensors of the launcher, observation devices, aiming devices, a ballistic computer unit with an indication unit, a current distributor for programming the number of shots in a volley and fire control, the distribution of current pulses from the power source through electrical circuits in a certain sequence and checking the serviceability of these circuits and the electric igniters of shells, a block of pulses for generating current pulses with specified parameters of the shells supplied to the electric igniters and blocking the launch of shells when the position of the launcher is unacceptable of the installation, as well as the wiring kit of connecting cables, according to the invention, the current distributor and the pulse unit are combined into a single unit of start-up equipment, made in the average dimensions of the current distributor and using the element base of digital devices with the ability to provide automatic self-testing of electrical circuits, automatic control of the integrity of the start circuits and the presence of docking of rockets with the guide tube of the launcher, indication of the number of shells in the guides, operating modes and status of the launcher.

At the same time, to indicate the number of projectiles in the guide tubes, operating modes and the status of the launcher, the launch equipment block contains indicators "COL" and "INF".

In this case, the starter equipment block contains the “KEY” indicator to display the invalid position of the key when it is turned on.

At the same time, the launch equipment block contains a numeric keypad (buttons 0...9), "ENTER" and "RESET" buttons for setting the number of shells in a volley.

At the same time, the launch equipment unit is configured to enter code commands to set combat and service modes of operation.

At the same time, the launch equipment block is configured to provide an alarm and indication in case the projectile does not come off after launch.

At the same time, the launch equipment unit is configured to automatically determine in the launcher the projectiles to be launched, in accordance with the order and quantity set by the operator.

At the same time, the start-up equipment block, made using the element base of digital devices, provides automatic self-shutdown and shutdown by the operator.

The analysis of the distinguishing features showed the following:

- combination of a power distributor and a block of impulses into a single block of start-up equipment using the element base of digital devices allows you to implement additional and automate existing functions, to make a block of start-up equipment in a single housing in the average dimensions of a current distributor;

- the possibility of automatic self-testing of electrical circuits eliminates the need for control by the operator by pressing the appropriate button;

- the ability to automatically monitor the integrity of the launch circuits and the presence of docking of rockets with the contacts of the guide tube of the launcher increases the overall reliability of the launcher, allows you to detect malfunctions and errors in the installation of shells in the guide tubes;

- the ability to indicate the number of shells in the guide tubes, operating modes and the state of the PU increases the information content and reduces the time for analyzing information and making decisions by the operator;

- an indicator for displaying an invalid key position allows you to inform the operator about an incorrectly executed sequence of commands;

- the ability to enter code commands allows you to enter commands to enable and configure combat, service and training modes of operation;

- the possibility of providing an alarm and indication in case of failure of the projectile after launch informs the operator about the occurrence of an emergency situation, the existing danger of a protracted (delayed) launch of the projectile and the need to remain ready for launch for a certain time;

- automatic detection in the launcher of projectiles to be launched, in accordance with the sequence and quantity set by the operator, reduces the time until the first descent of the projectiles due to the lack of a consistent supply of current pulses through empty guide tubes;

- the presence of automatic self-shutdown and shutdown by the operator provides additional protection against unauthorized starts.

The essence of the invention is illustrated by drawings, which show:

- in Fig. 1 - Scheme of the PU fire control system;

- in Fig. 2 - Starting equipment block;

The fire control system of a launcher of a multiple launch rocket system is intended for aiming at a target and launching unguided rockets and can be used on mobile (tracked, wheeled and other vehicles) and stationary objects as part of launchers for various types of offensive and defensive combat as a means fire support.

The fire control system (Fig. 1) PU MLRS contains power drives 1 pointing PU in the horizontal and vertical planes, sensors 2 position of the launcher, devices 3 observations, devices 4 aiming, unit 5 of the ballistic computer with the unit 6 display unit 7 launch equipment, wiring kit of connecting cables (not shown in the figure).

Power drives 1 pointing are designed to point the launcher at the target in azimuth (horizon), lifting the guide tubes 8 to a given angle (vertical) and holding it in the process of launching projectiles. Guidance power drives can be made as in the BM TOS-1A prototype from a horizontal guidance drive made using an electric motor, a vertical guidance drive, while lifting to a given angle is carried out by a hydraulic cylinder, control devices and auxiliary devices. The control devices for the guidance actuators of the prototype provide guidance of the launcher by the operator in manual mode and in automatic mode according to the horizontal and vertical guidance angles generated by the ballistic computer unit.

PU position sensors 2 are designed to track the position during aiming at the target and limit the maximum angle of vertical guidance.

Block 5 of the ballistic computer with the display unit 6 is a specialized computing device designed to generate the angles of horizontal and vertical guidance of the launcher for the preparation of firing, depending on the type of ballistics, range to the target, range to the target, the total elevation angle of the target and the trim and roll of the launcher when placement on a moving object, wind speed and directional angle, deviations of air temperature, projectile charge and atmospheric ground pressure from normal firing conditions.

Structurally, block 5 of the ballistic computer consists of a control panel, a housing with a computer installed in it, a power converter and external electrical connectors, a back cover, which are connected by screw-nut tightening pairs. The display unit 6 consists of a control panel, a housing and a back cover. The control panels contain the controls and indications.

The block 5 of the ballistic computer can optionally provide input of meteorological data by the operator in manual mode or receive it automatically from an external weather station 9. Sensors 10 of the trim and roll of the launcher are used when placing the launcher on a moving object, such as in the BM TOS-1A prototype, and are designed to determine the position of the carrier platforms. When placing the launcher on a stationary object, the trim and roll sensors of the launcher are not used.

Surveillance devices 3 are designed to monitor the terrain, target designation and fire adjustment, reconnaissance of targets and an approximate determination of the range to them. As the main observation device, a binocular combined periscope is used, the electron-optical system of which provides the possibility of observation in day and night modes, for example, TKY-3.

Aiming devices 4 are designed to search for and select moving and stationary targets, measure the range and total elevation angle of the target and the trim of the launcher (the angle of deviation of the line of sight of the rangefinder from the base plane of the platform). The value of the angle and range in the form of electrical signals is fed to the input of block 5 of the ballistic computer. Thus, a 1D14 periscopic laser rangefinder can be used as aiming devices, the principle of measuring the range of which is based on measuring the time it takes for a light signal to travel to a target and back.

The wiring kit of connecting cables (not shown in the figure) is designed for electrical connection of the components of the launcher fire control system.
