Abstract

Method of firing an artillery gun is that the aiming of the artillery gun on the target, firing projectile weapons, equipped with a source of radio signals, receiving radio signals at the artillery position, determine the coordinates of the point of fall of the firing projectile, coordinate shooting point, the firing direction is adjusted. The source of the firing projectile's radio signal is synchronized with the receiving position of the artillery position during the firing. And by changing the frequency of the received radio signal on the basis of the Doppler effect is determined by the value of the velocity of the projectile at the moments of radiation of radio signals, the difference in time between the previously known moments of radiation of radio signals and the moments of their reception at the artillery position is calculated from the position of the firing. Based on the obtained data, the coordinates of a certain number of points of the trajectory of the firing projectile's flight path are calculated and its extrapolation to the point of its fall is performed, after which the difference of the coordinates of the point of incidence of the firing projectile and the target is determined, on the basis of which the firing direction is adjusted.

Description

The useful model belongs to the field of weapons, in particular to artillery and mortar systems when firing from closed firing positions, methods of aiming artillery systems with unguided ammunition.

There is a well-known method of aiming an artillery gun by visual observation of the points of impact of the projectiles, which are equipped with smoke charges for better visibility (Bolshaya sovetskaya zncyclopedia. - M.: Sovetskaya zncyclopedia, 1974. -

T. 23. - P. 629-6301. At the same time, the firing corrector visually fixes the points of impact of the projectiles and determines their deviation from the position of the targets, and issues commands for correcting the firing direction.

The disadvantage of this method is the need for the corrector to be in the area of visual observation of the points of projectile fall, which is extremely dangerous or impossible in most cases of artillery application.

The closest in terms of technical essence is the method of firing from an artillery gun and the artillery system for its implementation (patent of the Russian Federation Mo2319100, publ. 10.03.20081. It consists in the fact that the firing of an artillery gun is carried out using homing projectiles equipped with a source of radio signals emitting a radio signal at the moment of the fall of a projectile, while this signal is re-emitted by three or four reflectors of radio signals, the coordinates of which are known, after which these radio signals are received at the artillery position and based on the measurement of their time shifts, the coordinates of the points of fall of the projectiles are calculated.

The disadvantage of this method is the complexity of its technical implementation and high cost, since it requires the use of three or four air or space-based aircraft.

The useful model is based on the task of creating a method of aiming an artillery gun, in which, due to the firing of aiming projectiles, which are equipped with a source of radio signals, which is synchronized with the receiving installation of the artillery position during the shot, and the source of radio signals emits a radio signal of a fixed frequency at moments determined in advance during the synchronization process time, and reception

From the radio signals at the artillery position, it is carried out with the determination of the angle of location and the directional angle of the finding of the aiming projectile, and based on the change in the frequency of the received radio signal based on the Doppler effect, the value of the speed of the aiming projectile at the moments of radio signal emission is determined, based on the time difference between the previously known moments of radio signal emission and the moments of their reception at the artillery position, the distance from the artillery position to the aiming projectile is calculated.

Based on the received data, the coordinates of a certain number of points of the trajectory of the aiming projectile are calculated and extrapolated to the point of its fall, after which the difference in the coordinates of the point of fall of the aiming projectile and the target is determined, on the basis of which the correction of the firing direction is carried out.

The task is solved by the fact that in the method of aiming an artillery gun, which consists in aiming an artillery gun at a target, firing homing projectiles equipped with a radio signal source, receiving radio signals at the artillery position, determining the coordinates of the point of impact of the homing projectile, determining the difference in the coordinates of the point the fall of the aiming projectile and the target, on the basis of which the correction of the firing direction is carried out, the radio signal source of the aiming projectile is additionally synchronized with the receiving installation of the artillery position during the shot, and the source of radio signals emits a radio signal of a fixed frequency at moments of time determined in advance in the synchronization process, and the reception of radio signals at the artillery position, it is carried out with the determination of the location angle sa and the direction angle u of the location of the aiming projectile, and by changing the frequency of the received radio signal based on the Doppler effect era is determined by the value of the speed of the projectile at the moment of radio signal emission, by the time difference between the previously known moments of radio signal emission and the moment of their reception at the artillery position. What is the calculation of distances 5; from the artillery position to the aiming projectile according to the formula:

Pis-vi5ip(O), based on the results of the calculated i-points of the trajectory of the projectile's flight, its extrapolation is carried out to the point of its fall.

The drawing shows a general image, which schematically shows the location of the Okhup coordinate system with the center at the artillery position, from where the firing projectile takes place and the reception of radio signals from the source of radio signals, which is placed in the projectile. The target projectile is shown by a conventional point

Si, with coordinates xu. The calculated distance to the projectile is 51. Through a and y, the position angle and the directional angle of finding the aiming projectile are shown, respectively. The extrapolated point of fall of the homing projectile is marked as Ц.
