Description

The invention relates to the field of combat vehicles equipped with a fire control system having, as part of the installer, time intervals.

A well-known installer of time intervals used in fire control devices of modern tanks, containing a unit installer time intervals, remote installer time intervals and transmitting device (see. Product 188A1. Technical description. 188A TO. Part 1. - C.63 Open edition. Prototype) .

It is designed to prepare an electronic remote-contact projectile fuse for detonation at a given point on the flight path.

The installer of time intervals, based on the signal about the flight time of the shells, ensures the generation (in manual mode) and input into the electronic remote-contact fuse of data on the time of its operation (in automatic and manual modes).

During operation, the installer of the time intervals interacts with the sight, ballistic computer and automatic loader.

The installer of time intervals has two operating modes - automatic and manual.

Information about the flight time for the shells is transmitted from the installer of the time intervals using a docking device mounted on the gear of the rotating conveyor.

The charging cycle begins by pressing the MH button on the sight at the measured range (or when the switch is on the remote control of the time installer in the “MANUAL” position). In this case, the cassette with the selected type is rotated to the output window, it rises to the information transfer line, where it is fixed by the signal from the limit switch in the conveyor rotation mechanism. The funnel of the docking device is extended to dock with the projectile and transmit information about flight time.

Next, the funnel of the docking device returns to its original position, and the signal from the end switch of the docking device continues to operate the charging machine in normal mode.

The manual mode is used when the laser rangefinder, ballistic computer and stabilizer are idle and also requires stopping the cartridge on the information input line.

The disadvantage of this device is the large preparation time of the shot due to the need to stop the cassette on the data input line, thereby reducing the combat effectiveness of the machine as a whole.

The objective of the present invention is to reduce the time for preparing a shot, simplifying the design and algorithm of the loading system and increasing the combat effectiveness of the machine.

A range input system comprising a time interval installer unit, a time interval installer panel and characterized in that the distance installer is located inside the rotating conveyor on a fixed part thereof; the dimensions of the range finder’s anchor allow cartridges with all types of ammunition to move between its poles without touching the head of the latest ammunition; the range ’size allows transmitting information about the time of detonation to the receiving coil of an electronic remote-contact fuse.

The outputs of the range finder are electrically connected to the installer unit of the time intervals and the electronic remote-contact fuse of the projectile, and the projectile is mechanically connected to the cartridge, which is mechanically connected to the cartridge position sensor, which, in turn, is electrically connected to the junction boxes and the control unit of the machine charging, the outputs of which are electrically connected with the unit of the installer of time intervals, the outputs of which have direct and feedback with the console of the installer of time intervals and ballistic computer, which, in turn, is in electrical communication with the sight, which is in electrical communication with junction boxes and the control unit of the autoloader.

The system also differs in that it is made with a simplified algorithm for the operation of the automatic loader: the absence in the algorithm of the input system of the range of the need to stop the cartridge on the information input line; without a limit switch located on the lifting mechanism of the cassettes of the charging machine.

The invention is illustrated in figure 1 and figure 2.

Figure 1 presents the functional diagram of the range entry system, figure 2 explains the design and location of the range finder.

The following notation is used in the figures: 1 - sight (P); 2 - cassette (K); 3 - cartridge position sensor (DPK); 4 - junction boxes and the control unit of the autoloader (RK and BU); 5 - ballistic computer (BV); 6 - block installer time intervals (BUVI); 7 - console installer time intervals (PUVI); 8 - range installer (UD); 9 - electronic remote contact fuse (EDKV); 10 - projectile (C); 11 - anchor; 12 - the primary winding of the transformer; 13 - receiving coil.

Sight 1 is designed to measure range and the gunner to conduct day and night from a place and in the movement of effective aimed fire from a gun and a coaxial machine gun.

Cassette 2 is used to place a shot of any type.

The position sensor of the cartridge 3 is part of the automatic loader and provides information for braking and stopping the rotating conveyor.

Junction boxes and the control unit of the autoloader 4 are designed to accommodate the controls of the autoloader and generate electrical commands that determine the sequence of operation of its mechanisms.

Ballistic computer 5 is designed to solve the problems of generating and issuing values of aiming angles, lateral lead, shot resolution zones, signals about the flight time of shells and providing guidance to the gun and turret.

Block installer time intervals 6 is designed to generate time to the goal in manual mode.

The panel of the installer of time intervals 7 is intended to control the operation of the installer of time intervals in manual mode.

The rangefinder 8 is designed to provide input of information about the time of detonation into an electronic remotely-contact munition fuse in a non-contact manner during the movement of the cartridge with these ammunition.

The design of the rangefinder is illustrated in figure 2, which presents a functional diagram of the rangefinder, which includes the following elements: anchor 11; primary winding 12; the receiving coil 13 of the electronic remote contact fuse.

The work of the range finder: when voltage is applied to the primary winding 12 of the range finder, when the electronic remote-contact fuse 9 moves between the poles of the armature 11, an electric current starts to flow in the receiving coil 13 (secondary winding) - the device starts to work like a transformer. That is, the value of the flight time of the projectile 10 is transferred from the primary winding of the transformer 12 to the receiving coil 13 of the electronic remote contact fuse 4.

This device is placed inside a rotating conveyor on a fixed part thereof. The dimensions of the range-setting armature 11 allow the cartridges 2 with all types of ammunition 10 to move between its poles without touching the head of the ammunition. And their dimensions (indicated in FIG. 2) are sufficient for transmitting information about the time of detonation to the receiving coil 13 of the electronic remote contact fuse 4: the length of the poles allows the receiving coil 13 of the electronic remote contact fuse 9 to be under the influence of an electromagnetic field necessary to enter the range time.

Electronic remote-contact fuse 9 is designed to provide undermining of ammunition at a given point on the flight path based on the data entered into it. An electronic remote-contact fuse is mounted on the projectile 10, which is located in the cartridge 2.

Ammunition (projectile) 10 is intended for direct destruction of enemy manpower by a signal from an electronic remote-contact fuse. The projectile is installed in cassette 2.

The operation of the device: after measuring the range and setting the appropriate ballistics on the sight 1, information about the selected type of ammunition 10 is fed into the junction boxes and the control unit 4. In this case, the cartridge 2 with the selected type of ammunition 10 starts moving to the dispensing window.

The signal from the junction boxes and the control unit 4, which carries information about the beginning of its operation, enters the unit of the installer time intervals 6, there it is converted into a pulse going to the ballistic computer 5. In response to this signal from the ballistic computer 5 6 receives a signal proportional to the flight time of the projectile 10.

At the moment when the position of the cartridge 2 ensures the system is ready for range entry, the corresponding signal is sent from the junction boxes and the control unit 4 to the installer unit of the time intervals 6. After that, the installer unit of the time intervals 6 gives a signal proportional to the flight time of the projectile 10 to the input of the range installer 8.

From the range finder 8 to the electronic remote-contact fuse 9, the value of the fuse response time is transmitted.

The readiness of the system to enter the range is determined by the relative position of the cartridge 2 with the ammunition 10 and the range finder 8. When the cartridge 2 approaches the range finder 8 from the position sensor of the cartridges 3, a signal is received in the time installer 6 unit, by which the range finder 8 is turned on.

One-way rotation of the conveyor allows the use of a single rangefinder 8. Its dimensions allow the cartridges 2 with any types of ammunition to move freely and at the same time ensure reliable data transmission to the electronic remote-contact fuse 9.

When the range input system is in manual mode, its operation procedure will remain the same. The exception is that the range is entered using potentiometers located on the console of the installer of time intervals 7, and the calculation of flight time is carried out not in the ballistic computer 5, but in the unit of the installer of time intervals 6.

The absence of the need to stop the cartridge on the information input line in the algorithm for operating the range input system allows you to refuse to use the limit switch located on the lifting mechanism of the cassettes of the charging machine, which is designed to signal the output of the cartridge to the information input line. Accordingly, the algorithm of the automatic loader is simplified.

The proposed range finder is made of the element base used in the systems of objects of armored vehicles.

Thus, the proposed range entry system has the following advantages in comparison with the prototype: it provides input of information about the time of detonation into an electronic remotely-contact munition fuse in a non-contact way without stopping the cartridge with these ammunition, thereby reducing the preparation time of the shot, simplifying the design of the elements of the automatic loader, algorithm of his work and increases the combat effectiveness of the tank.
