Description

The invention relates to the field of combat vehicles equipped with sighting systems having a lateral lead generation device.

A device for generating lateral lead-outs is used in sighting systems of modern tanks (see Tank T-72A. Technical description and operating instructions. Book one. Military publishing house. Prototype. 1986 - 79 pp.). It is intended (when working together with a sight - range finder) to automatically generate a lateral lead angle by entering its value into the digital indicator of the display unit located on the eyepiece of the sight - range finder.

The device for generating lateral anticipations provides automatic generation of the magnitude and sign of lateral anticipation taking into account the measured range, type of ballistics, speed of relative movement of the target, meteorological conditions.

The lateral lead generation device kit includes an electric unit; correction potentiometer; display unit and wiring kit.

To determine the angle of lateral lead (see Tank T-72A. Technical description and operating instructions. Book one. Military Publishing. 1986 - 80-81 p.) The following actions are performed: having chosen a target, the gunner sets the type of shot and turns on the automatic loader. Then he accompanies her with a luminous mark and, having equalized the speed of pointing the tower with the speed of relative movement of the target, he presses the range measurement button. Scope of sight - rangefinder moves, practicing the measured range. The measured range in the form of voltage enters the electrical unit. On the digital indicator of the indication unit of the lateral lead generation device, the magnitude and sign of the correction that existed at the time of measuring the range are displayed. The value of lateral lead is generated in the form of a three-digit number with a resolution of 0.5 etc.

If aiming should be carried out by the mark of the lateral correction scale, located to the left of the central aiming mark, the “-” sign is displayed in front of the numbers determining the magnitude of the correction. Aiming and firing are made by the mark of the lateral corrections scale corresponding to the magnitude and sign of the corrections available on the digital indicator at the moment of pressing the range measurement button. The device provides for storing the magnitude and sign of the correction that existed at the time of pressing the range measurement button, which is stored in the digital indicator for the entire time the button is pressed. After releasing the ranging button, the digital indicator goes off.

The disadvantages of this device are:

1. The need to remember the magnitude and sign of the lateral lead;

2. The need to recalculate the magnitude and sign of the lateral lead into the number of grades of the lateral correction scale and the location of the necessary mark relative to the central aiming mark;

3. The need for manual entry of the lateral lead angle by the gunner in the position of the tower;

4. The repetition of the entire process with repeated measurement of range.

In fire control systems with tank ballistic computers and independent stabilization of the field of view, a system is used to enter the angle of lateral lead into the position of the weapon. The inapplicability of this method in the fire control system of the T-72B tank is expressed by the absence of 2-plane stabilization of the field of view (only the vertical field of view is stabilized).

The objective of the present invention is to provide automation of the process of introducing the angle of lateral lead in the position of the tower.

This problem is solved by introducing into the known device a control unit and a tower position sensor, assembled from an element base used in systems of objects of armored military equipment.

The display unit is left as part of the system to control the correct introduction of the lateral lead angle, for the introduction of the previous method in the event of a system malfunction, as well as during adjustment.

At the same time, in the automated system for inputting the angle of lateral lead, comprising: an electrical unit; indication unit; correction potentiometer; the electrical installation kit according to the invention has additionally introduced a control unit whose inputs are in electrical communication with the electrical unit and the tower position sensor, one output is in electrical communication with a stabilizer, which, in turn, is mechanically connected with the tower, and the other output is in electrical communication with the position sensor tower, which has a mechanical feedback with the tower, the outputs of the electrical unit are in electrical communication with the display unit and the control unit, and the input is in electrical communication with the potential Trom amendments.

The invention is illustrated in the drawing, which shows a functional diagram of an automated system for inputting the angle of lateral lead, which includes the following elements: 1 - electrical unit; 2 - display unit; 3 - correction potentiometer; 4 - control unit; 5 - stabilizer; 6 - tower; 7 - tower position sensor.

The electrical unit 1 is designed to ensure the operation of the stabilizer, control device and firing circuits, as well as for partial connection with the weapon stabilizer 5.

Display unit 2 is intended for reading corrections of lateral anticipations.

The corrections potentiometer 3 is intended to introduce corrections for deviation of firing conditions from normal.

The control unit 4 is designed to generate control signals for the position sensor of the tower 7 and the stabilizer 5.

The stabilizer 5 is designed to stabilize and aim the gun and the machine gun coaxial with it in the vertical and horizontal planes installed in the tank, in order to increase the efficiency of fire when firing from tank weapons on the move.

The position sensor of the tower 7 is designed to monitor the rotation of the tower 6 by a given angle of lateral lead and control the proportionality of the rotation, as indicated by the control unit 4, which stops signaling the stabilizer 6 for further movement.

Operation of the device: after measuring the range of the moving target by the gunner, the signal corresponding to the direction and angle of the lateral lead, as well as the signal corresponding to the distance to the target D, are received from the electrical unit 1 to the control unit 4. Control unit 4, by applying a signal to enable the sensor to work the position of the tower 7, on the basis of these signals, as well as the feedback signal from the position sensor of the tower 7, generates a control voltage supplied to the stabilizer 5. In the future, the system works as when pointing the tower horizontally.

The magnitude and polarity of the control voltage, as well as the duration of its supply, correspond to the rotation of the tower 6 by the angle of lateral lead of a given magnitude and direction.

The position sensor of the tower 7 is mechanically connected to the tower 6 and electrically connected to the control unit 4. It monitors the initial value of the “inconsistency” of the existing direction of the tower 6 with the necessary (with lateral lead), as well as the degree of mining by the tower 6 of the lateral lead (including accompanied by the target). These values in the form of a feedback signal are supplied to the control unit 4. When the tower 6 reaches the lateral lead angle, the signal and the system stop working.

With the obtained lateral lead value, the system works until the next range measurement. Maintain a constant angle of lateral lead when tracking a moving target, it is necessary for the gunner to manually move the control panel housing.

Thus, the proposed automated lateral angle input system has the following advantages compared to the prototype: the algorithm of the gunner’s work during the preparation of the shot is simplified, the preparation time of the shot is reduced, and the accuracy of aimed fire at enemy targets is also increased.
