The disadvantage of the data of the method and device is the inability to determine the dispersion characteristics of the shells. One of the most important factors determining the random nature of the damage caused by shooting a target is the dispersion of the means of destruction - shells, bombs, missiles, torpedoes, etc. Dispersion is the random deviation of the relative trajectory of the projectile from the calculated point. Usually, the center of the target is considered as the calculated point. Dispersion takes place with any type of shooting and is caused by various errors that accompany aiming and shooting.

Firing errors cause random conditions for the separation of weapons from the gun or aircraft, which are determined by the individual design features of its suspension on the aircraft and installation vibrations under the influence of recoil forces when firing automatic weapons. Deviations of the ballistic characteristics of the projectile (mass, size, shape, intrinsic initial velocity, etc.) from the nominal values and atmospheric turbulence cause a random deviation of the projectile’s flight time from the calculated value, which leads to a firing error called ballistic (Kalabukhova E.P.

Description of the operation of the device.

To determine the characteristics of the dispersion of shells when firing from artillery weapons, a target situation is created in the form of two spaced apart non-contact sensors (3, 4) and an electronic target 5, the outputs of which are connected respectively to the inputs of the block 6 for determining the parameters of the movement of the shells and block 7 for signal processing (Fig. . one).

The design of non-contact sensors (3, 4) and the electronic target 5 is made in the form of perpendicularly arranged lines of emitting diodes 12 and lines of photodetectors 13.

To carry out the aiming on the electronic target 5, paper is glued, with the center of aiming in the form of a crosshair. A cold shooting tube (TX) is inserted into the barrel channel of an artillery weapon (AO) and trunks are guided at the center of aiming of the electronic target 5, after aiming the AO trunks, the TXP is removed from the barrel channel.

Then, shooting is performed on the selected picture plane in the form of an electronic target 5, the Cartesian coordinates of the hit points of the shells 2 are fixed.

At the time of flight of shells relative to the first 3 sensors, a certain combination of sensitive elements of the line of photodetectors 13 is triggered (Fig. 1, Fig. 2). The signals from the outputs of the photodetectors 13, sensor 3 through the first 17 and second 18 OR elements are fed simultaneously to the start of the first 15 and second 16 measuring device and to the first and second inputs of the first 21 logic block (Fig. 1, Fig. 2).

At the time of flight of the projectile relative to the second 4 sensors, the following combination of sensitive elements of the line of photodetectors 13 occurs (Fig. 2). The signals from the outputs of the photodetectors 13, the second 4 sensors through the third 19 and fourth 20 OR elements arrive simultaneously at the stop of the first 15 and second 16 of the measuring device and the first and second inputs of the second 22 logic unit (Fig. 1, Fig. 2).

Thus, it is possible to determine the velocities of shells on the basis of measuring their time intervals relative to two non-contact sensors spaced in space (3, 4).

Signals about the flight speeds of shells in the horizontal and vertical planes come from the outputs of the first 15 and second 16 measuring instruments (which are the first and second outputs of the projectile motion determination unit 6) respectively to the third and fourth inputs of the signal processing unit 7 (third and fourth inputs of the unit 25 memory) (Fig. 2, Fig. 3).

The signal codes arriving at the first and second inputs of the logic unit 21 correspond to the coordinates of the projectile span relative to the first 3 sensors (Fig. 2) and provide the operation of certain combinations of the matrix of elements And 27, the output signals of which trigger the combination of the matrix of triggers 28, the output which are fed to the group of fifth inputs of the signal processing unit 7 and, accordingly, to the fifth inputs of the memory unit 25 (Fig. 4).

The signal for resetting the logic elements of logic blocks (21, 22, 23) comes from the power supply 30 through the differentiating circuit 29 to the second inputs of the trigger matrix 28.

Similarly, the second block 22 of the logic determines the coordinates of the flight of shells relative to the second 4 sensors, the signals from the output of block 22 of the logic are fed to the group of sixth inputs of block 7 of the signal processing and, accordingly, to the sixth inputs of block 25 of memory.

When shells hit the electronic target 5, the signals from its first and second outputs are fed to the first and second inputs of the signal processing unit 7.

Moreover, the group of first and second inputs, as well as the third, fourth, group of fifth and sixth inputs of the signal processing unit 7 is, respectively, the group of first and second inputs of the logic unit, as well as the third, fourth, group of fifth and sixth inputs of the memory unit 25.

The third and fourth inputs, a group of fifth and sixth inputs of the memory unit 25, respectively receive information on the speeds of the projectiles and the coordinates of their flight relative to the first 3 and second 4 non-contact sensors.

From the group of outputs of the block 22 of the logic, the signals are simultaneously transmitted to the group of the second inputs of the block 25 of the memory and the inputs of the block 24 for determining the characteristics of the dispersion of shells.

Block 24 determining the characteristics of the dispersion of shells determines the mathematical expectation of the center of dispersion of shells in the form of expressions

,

,

where N _p is the number of shots, Z _K Y _k is the coordinates of the projectile hit with one shot, and also determines the mean square deviation in the form of expressions:

.

.

The signals from the output of the block 24 determining the characteristics of the dispersion of shells are fed to the first group of inputs of the block 25 of the memory. The memory unit 25 records data on speeds, motion coordinates, hit coordinates and dispersion characteristics of the shells. From the output of the memory unit 25, this information is transmitted via the contactless device 26 via the contactless line to the receiving device 8.

The signals from the output of the receiving device 8 through the device 9 coordination arrive at the input of the microcomputer 10.

Microcomputer 10 determines the trajectory of the projectiles based on the analysis of the coordinates of the flight of the shells relative to the first 3 and second 4 non-contact sensors, determines the dependence of the dispersion characteristics of the shells on their speeds and transmits signals to indicator 11.

On the indicator 11 displays information about the coordinates of the hit of shells in the target 5 and the characteristics of the dispersion of the shells.

Thus, the present invention provides for the determination of information about speeds, coordinates of movement and hit of shells, dispersion characteristics of shells when firing from artillery weapons.
