Description

The invention relates to the field of military equipment and can be used to control the rate of fire of automatic aircraft guns with an electro-firing mechanism for firing when using cartridges with electric capsules-igniters (ECV).

There is a method of firing automatic weapons of a combat vehicle in the description in the invention No. 2659464 from 07/03/2017, publ. 07/02/2018, IPC No. 2659464, including preparatory operations for the alignment of the zero line of sight of the sight relative to the weapon and its targeting at a low rate of fire with the determination of amendments to the offset of the sighting mark of the sight relative to the axis of the barrel of the weapon in horizontal and vertical planes, characterized in that it additionally carry out the targeting of weapons at a high rate of fire with the determination of amendments for the offset of the aiming mark of the sight relative to the axis of the channel of the barrel of the weapon in two planes, and as part of the system fire control panels of a combat vehicle additionally include a sight with independent stabilization of the field of view in two planes and an amendment input unit that provides offset on the basis of the interpolation algorithm of the axis of the barrel of the weapon in two planes with the help of the gun stabilizer pointing actuators relative to the aiming mark of the sight when shooting at low to large, taking into account the results of the shooting of weapons at a given rate of fire.

Disadvantages: insufficiently high firing efficiency, as the method does not allow you to choose an effective rate of fire depending on the distance to the target.

Closest to the claimed technical solution for the technical nature and the technical result achieved is a method of firing automatic weapons of a combat vehicle (Suvorov SV. BMP-1, BMP-2 and BMP-3 infantry fighting vehicles. M.: KM strategy: Yauza: Eksmo, 2011 .-- 128 p.). The described method is adopted as a prototype of the invention. Switching the rate of fire from the gun is carried out by a switch located on the control unit. For remote control of the trigger mechanism, the electric trigger is designed:

- at a low rate of fire (TEMP switch is in position M) pulses with a frequency of 200-240 per minute are fed to the electromagnet; shots follow at the same frequency;

- at a high rate of fire (the TEMP switch is in position B), a constant voltage is applied to the electromagnet, the sear is constantly drowned and shooting is carried out at a high pace.

Disadvantages: insufficiently high firing efficiency, as the method does not allow you to choose an effective rate of fire depending on the distance to the target.

Effect: increasing the effectiveness of the combat use of AAO for air and ground targets.

The technical result in the method of controlling the rate of fire of automatic aircraft guns with an electrozapal firing mechanism is achieved due to the fact that using a radar sighting system (RLPK) or optical radar station (OLS), target detection and recognition are performed, the range and angular coordinates of the target are determined, and the approach speed for the purpose, while information about the parameters of the target is transmitted to the on-board digital computer (BCM) in which it is processed and the predicted yes is calculated firing accuracy, then the processed signal of the firing range, presented in the form of a machine code, is sent to the windshield indicator (ILS) in the cockpit (operator) and each bit of the code corresponds to its range, with the value of the range to the target is assigned a code received at the decoder and converted into electrical impulses with a repetition rate corresponding to the rate of fire for the calculated range, electrical impulses are fed to an electronic key that opens by pressing the battle button (BC), when volume, voltage is supplied to the gun’s electric guns, the projectile’s igniter is activated, and a shot is fired.

The probability of hitting a target when using aviation artillery weapons (AAO) depends on the rate of fire, range and the striking properties of APS. The proposed method of controlling the rate of fire from automatic aircraft guns with an electro-zapalny shooting mechanism solves the problem of choosing the rate of fire depending on the distance to the target, which allows you to control individual dispersion in a wide range of possible shooting conditions, increasing the effectiveness of combat use of AAO for air and ground targets. And it does not require the crew to reach effective firing range, which reduces the time spent in the target air defense zone when operating on ground targets, and reduces ammunition consumption during firing.

A comparative analysis of the proposed solution with the prototype allows us to conclude that the claimed invention meets the conditions of patentability: it is new, has an inventive step and is industrially applicable.

The inventive method is as follows.

Using a radar sighting system (RLPK) or optical radar station (OLS), depending on the conditions of combat use, the target is detected and recognized, target parameters are determined (range and angular coordinates of the target, speed of approach to the target). Information about the target parameters is transmitted to the on-board digital computer (BCM) in which the information is processed and the anticipated firing range is calculated. After that, the processed signal of the firing range is fed from the output register of the BCMC processor to the windshield indicator (ILS) in the cockpit of the pilot (operator). The processed signal of the firing range is presented in the form of a sixteen-digit code, where each bit corresponds to its range. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate corresponding to the rate of fire for the calculated range, which are fed to the input of the electronic key. By pressing the battle button (BC), the voltage pulse opens the electronic key, the voltage is supplied to the gun’s electric guns, the projectile’s ECV is triggered and a shot is fired. After returning the parts and mechanisms of the gun to the initial position for firing, the next shot does not occur until the next impulse arrives at the input of the electronic key. Thus, the rate of fire is determined by the pulse rate of the electric voltage, depending on the distance to the target.

After detection and target recognition, the digital computer processes the information and calculates the anticipated firing range, for example, 485 meters. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate corresponding to the rate of fire for the calculated range.

In this case, for a range of 485 meters, the firing rate of 1,500 rounds per minute is selected. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate of 25 Hz, a voltage pulse is fed to the input of the electronic key. By pressing the combat button (BC), the voltage pulse opens the electronic key, the voltage is supplied to the gun’s electric guns, the cartridge’s ECV is triggered and a shot is fired. After the return of the parts and mechanisms of the gun to the initial position for firing, the position of the next shot does not occur until the next impulse arrives at the input of the electronic key.

The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate corresponding to the rate of fire for the calculated range.

where N is the rate of fire; D _A - anticipated firing range.

In this case, for a range of 1100 meters, a rate of fire of 900 rounds per minute is selected. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate of 15 Hz, a voltage pulse is fed to the input of the electronic key. By pressing the combat button (BC), the voltage pulse opens the electronic key, the voltage is supplied to the gun’s electric guns, the cartridge’s ECV is triggered and a shot is fired. After the return of the parts and mechanisms of the gun to the initial position for firing, the position of the next shot does not occur until the next impulse arrives at the input of the electronic key.

Example 3

Using a radar sighting system (RLPK) or optical radar station (OLS), depending on the conditions of combat use, the target is detected and recognized, target parameters are determined (range and angular coordinates of the target, speed of approach to the target).

After detection and target recognition, the digital computer processes the information and calculates the anticipated firing range, for example, 1,600 meters. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate corresponding to the rate of fire for the calculated range.

where N is the rate of fire; D _A - anticipated firing range.

In this case, for a range of 1600 meters, a rate of fire of 600 rounds per minute is selected. The value of the range to the target is assigned a code that goes to the decoder. In the decoder, the code is converted into electrical pulses with a repetition rate of 10 Hz, a voltage pulse is fed to the input of the electronic key. By pressing the combat button (BC), the voltage pulse opens the electronic key, the voltage is supplied to the gun’s electric guns, the cartridge’s ECV is triggered and a shot is fired. After the return of the parts and mechanisms of the gun to the initial position for firing, the position of the next shot does not occur until the next impulse arrives at the input of the electronic key.

Using the claimed invention will allow you to change the rate of fire, depending on the range, providing increased efficiency in the combat use of AAO for air and ground targets.
