Description

The invention relates to the field of weapons and military equipment, in particular to fire control systems (LMS) of combat vehicles (BM) such as tanks, infantry fighting vehicles, armored personnel carriers, BMDs, etc.

As the closest solution, the control and guidance system of the weapons of the combat vehicle described in the patent for the invention of the Russian Federation No. 2553712 and selected as a prototype can be considered.

The presented system contains control panels for horizontal and vertical guidance (GN and HH), armament control system equipment, a stabilization device with position sensors of an inertial object independently stabilized in space by GN and HH, an armament guidance system control unit (START), to which two circuits are connected, horizontal and vertical guidance, namely: a power amplifier, a motor and a gearbox connected in series, position sensors of the horizontal (tower) and vertical (gun) respectively guidance channels, the outputs of which, as well as the absolute angular velocity sensors of horizontal and vertical guidance are connected to START.

Common features of the prototype and the claimed technical solution are the master device of the inertial stabilization object independently stabilized in space, the equipment of the control system of the fighting compartment, control panels for GN and HV, the stabilizer control unit (in the claimed technical solution - the control unit of the weapon guidance system), power amplifiers, weapons gearboxes and electric motors, turret position sensor, weapon HV position sensor, roll and pitch sensor (included in the armament control system equipment), gun absolute velocity sensors according to GN and HV.

The disadvantages of the prototype are the impossibility of installing additional stabilized weapons, and as a result, the inability to rationally choose your type of weapons and ammunition, adapted for a specific purpose, the lack of information channels for exchanging with other devices, which complicates the diagnosis and the ability to install on other combat vehicles.

The problem to which the claimed technical solution is directed is to increase the accuracy and efficiency of firing at an expanded range of targets, in a wide range of conditions for combat use; expanding the functional capabilities of the BM, improving the operational characteristics of the weapons control and guidance system (SUNV).

The problem is solved by the control system and guidance of the armament of the combat vehicle, which contains control panels for GN and HV, armament control system equipment, a stabilization device with position sensors of an inertial object independently stabilized in space along GN and HV, the control unit for the weapon guidance system (START) to which two circuits are connected, horizontal and vertical guidance, namely: a power amplifier, a motor and a reducer connected in series, a position sensor of the horizontal (tower) and vertical (gun) guidance channels, the outputs of which, as well as the absolute angular velocity sensors of horizontal and vertical guidance are connected to the control unit of strategic offensive arms, while the new one is that the weapon guidance system (strategic offensive arms) is configured to connect to the first input-output, which is the first input-output of the control unit of the strategic control unit, through the CAN-1 information channel, to the stabilization master withposition sensors of an inertial object independently stabilized in space by GN and HV, by the second input-output, which is the second input-output of the strategic offensive arms control unit, via CAN-2, to the device for generating ballistic corrections of firing, which is part of the armament control system equipment, and includes additional vertical guidance loops in the form of a series-connected motor and gear, a launcher position sensor (launcher) of small-caliber launcher and a large-caliber launcher, left and right, with position sensors mechanically connected to the corresponding launchers, while the inputs of these loops are connected respectively to to the second or fourth outputs of the HV power amplifier, the third input of the strategic offensive arms control unit via an internal digital information exchange channel of the CAN type is additionally electrically connected to small-caliber PU position sensors, larger-caliber PU position sensors, as well as gun position sensors and absolute angle sensors axes of horizontal and vertical guidance, while switching different types of weapons is carried out in the strategic offensive arms control unit on commands from the weapons control system equipment.

The technical result provided by the implementation of the proposed technical solution is achieved due to the fact that:

- additional stabilized weapons, in the form of right and left launchers of larger-caliber SD and small-caliber SD, operating in the independent stabilization mode, allows operator control and automatically selects the appropriate weapons;

- digital angular position and angular velocity sensors are used with lower values of the absolute error of the output signal;

- signals are transmitted directly in a digital code, without additional intermediate conversions of values, due to which the additional errors caused by them are eliminated;

- enhanced operational characteristics of the SUNW and the possibility of its diagnosis and adaptation to other weapons control systems due to the availability of information exchange channels between the equipment of the control system of the combat compartment and the SUNW.

It is the so-organized weapon control and guidance system that provides increased firing efficiency for an expanded range of targets, in a wide range of combat use conditions. Thereby, the object of the invention is achieved.

Comparative analysis with the prototype shows that the claimed BM control and guidance system is distinguished by the presence of new elements, namely:

- an engine and a vertical guidance gear of a small-caliber launcher;

- engine and gearbox for vertical guidance of the launcher of UR of larger caliber, left and right;

- small-caliber PU position sensor;

- a PU position sensor of a larger caliber, left and right;

- CAN information channels.

Comparison of the claimed solution with other technical solutions shows that the individual newly introduced elements are quite well known in the art, but introducing them in the indicated connection into the LMS allows solving the tasks posed.

The invention, its technical feasibility and industrial applicability are illustrated by the drawing shown in FIG. 1, which shows a functional diagram of a control system and guidance of weapons of a combat vehicle.

The arms control and guidance system (START) comprises START control unit (BU SUNV) 3, power amplifiers for vertical 5 and horizontal guidance 6, a horizontal guidance engine (turret) 7, vertical guidance engines for gun 8, small-caliber missile launchers 9 and two missile launchers larger caliber 10, 11, position sensors of the tower 19, guns 20, small-caliber launchers 21, two larger launchers 22, 23, angular velocity sensors (DLS) of the vertical 12 and horizontal guidance of the gun 13, as well as gunner 1 and commander 2 guidance panels , armament control system equipment 4, a master device of an inertial stabilization object independently stabilized in space according to GN and HV 24, the first input-output of the SUNV 3 control unit being connected via a CAN-1 digital data exchange channel to a master device of an inertial stabilization object independently stabilized in space by GN and VN 24 and is the first external input-output SUNV, the second input-output BU START 3 is connected through the CAN-2 channel with a ballistic correction device structurally included in the armament control system equipment 4, it is also an external, second input-output of strategic offensive arms, and the third input, which is internal to strategic offensive arms, is connected to the remote control system via an internal digital channel CAN-CHB vertical 12 and horizontal guidance of the gun 13, with position sensors of the tower 19 (along the horizontal channel), and along the vertical channel with the position sensor of the gun 20, the position sensor of the small-caliber launcher 21, the left and right launcher of larger caliber 22, 23, which (sensors) are interconnected, in turn, with the outputs of the corresponding gearboxes 14-18, the inputs of which are connected to the outputs of the motors 7-11, respectively, the inputs of which are connected respectively with the first or fourth outputs of the vertical guidance power amplifier 5, internal third and fourth outputs of the START 3 are connected to the inputs of power amplifiers, respectively, vertical 5 and horizontal induced 6, and the control panels of the gunner 1 and commander 2 are connected via the CAN-3 information channel to a master device of an inertial stabilization object independently stabilized in space by GN and HV 24.

BU SUNV 3 provides stabilization and stable guidance of weapons when firing from a place, on the move and afloat with all types of weapons available in the BM:

- guns

- SD of small caliber,

- UR larger caliber.

The CAN-CHB channel is used for real-time information exchange between the strategic offensive arms control unit and the angular position sensors of various types of weapons and turrets, as well as the gun’s angular velocity sensors, both vertically and horizontally.

The functioning of the armament complex is ensured by the joint work of strategic offensive arms, the master device of the inertial stabilization object independently stabilized in space and the armament control system equipment.

The principle of functioning of the SIRS consists in the principle of “mark on target” traditionally used in control systems of this type of BM, in which aiming the weapon at the target consists in tracking the target with a line of sight (center of the aiming mark on the video monitor screen) in manual or automatic mode, and constant monitoring lines of sight with gun barrels taking into account calculated angular corrections.

The sight line of sight has an independent two-plane gyroscopic stabilization, and its guidance through the vertical and horizontal guidance channels is carried out manually from the gunner’s guidance panel 1 or gunner’s guidance panel 2, or in auto tracking mode according to commands proportional to the required guidance speed. The operating modes of the weapons complex as a whole and its individual components are set by a set of control commands received in the case of manual accompaniment from the gunner’s guidance panel 1 or commander’s guidance panel 2.

In the “Main” mode, the weapon from which the firing is being carried out, monitors with the help of electromechanical drives the position of the stabilized sight line of sight of the gunner’s sight (PN), which is guided by the gunner with the help of the gunner’s remote control (PN-N), with the arms control system issuing commands on measuring ranges, shooting, switching types of ammunition, as well as controlling the functions of PN. The gunner can use a target tracking machine.

The commander in the “Basic” mode, using PN-K, searches for targets in manual, semi-automatic and automatic modes, measures the range to the target, and commands to measure the distance through the commander’s sight (PC) are issued to SUNV, and he guides the stabilized line of sight of the PC , gives target designation to the gunner with the possibility of transmitting the target captured by the tracking machine, controls the PN functions (changing the field of view, adjusting and adjusting television and thermal images (brightness, contrast, focusing), works with the optical location detector).

In the “Main” mode, the BVPB ballistic correction generating unit, which is part of the armament control system equipment, calculates and processes the vertical and horizontal lead corrections taking into account the following parameters: type of ammunition, current range to target, air temperature, charge temperature, atmospheric pressure, lateral and the longitudinal component of the wind, the angular velocity of the line of sight, the angle of heel of the machine, the elevation angle of the target.

Corresponding information comes from environmental sensors, roll and pitch sensors, internal position sensors received via digital CAN communication channels. The angular velocity of the target is determined using the values of the guidance commands received via a digital channel at the input of the PN.

The operation modes of the SUNW (change of operating modes) are controlled from the armament control system equipment by activating the corresponding buttons. At the same time, control commands are issued to the CAN-2 channel of information and logical interaction, by which switching of operating modes without delays and interruptions of operation is provided.

Any branch (drive) of strategic offensive arms, for example, a tower drive, operates as follows:

the output signal of the power amplifier GN 6 rotates the shaft of the electric motor GN 7, which, in turn, rotates the turret with the mounted weapons in the direction determined by the stabilization master with a position sensor of an inertial object 24 independently stabilized in space, taking into account the angular correction for GN, calculated by the device for calculating ballistic corrections, which is part of the equipment of the arms control system 4.

Similarly, the VN motor (8-11) selected in the control unit of the СУНВ 3 through the corresponding VN gearbox (15-18) rotates the gun or the selected launcher in the direction determined by the stabilization master with a position sensor of an inertial object 24 independently stabilized in space by VN taking into account VL angular correction, calculated accordingly by the device for calculating ballistic corrections for the selected type of weapon

Thus, the BM control and guidance system claimed as an invention allows:

- increase firepower, ensuring effective destruction in a wide range of conditions of combat use of the entire range of targets intended for BM of the type in question, by using, in addition to the gun, two types of guided weapons, it becomes possible to choose specialized weapons for each type of target, while the launchers of UR work in independent stabilization mode, similar to the main weapons;

- to improve the accuracy and speed of the weapon system through the use of digital sensors of angular position and angular velocity with lower values of the absolute error of the output signal, direct transmission of signals in a digital code, without additional intermediate conversions, which eliminates additional errors;

- to increase the operational characteristics of the control system and the possibility of its diagnosis and adaptation to other weapons control systems due to the availability of information exchange channels between the equipment of the control system of the fighting compartment, the master device of the inertial stabilization object independently stabilized in space by horizontal and vertical guidance and SUNV,

- to provide increased reliability, as well as unification, both in the sense of using various types of armored vehicles: tanks, infantry fighting vehicles, armored personnel carriers, infantry fighting vehicles, and for use in fixed and sea-based facilities.
