Firing specification calculation system and firing specification calculation method of a projectile {SYSTEM AND METHOD FOR CALCULATING GUN FIRE SPECIFICATION OF PROJECTILE}

The present invention relates to a system for calculating shooting data of a projectile and a method for calculating shooting data, and in particular, a system for calculating shooting data of a projectile based on characteristics of a projectile and a range of an effective range, and calculating shooting data of a projectile using the same It's about how to do it.

Various projectiles generally used for military purposes are intended to hit enemy camps by firing cannons. If the target is stationary, it is sufficient to aim at the target and fire the shells, but if the target is moving, the shells must be fired by predicting the target's future position. As such, the military uses a fire control system that predicts the future position of a moving target and provides this information to naval guns. Such a fire control system includes a tracking sensor, a shooting information calculator, and the like. Recently, various cutting-edge technologies have been attempted to improve the accuracy of prediction in predicting the future position of a target by such a shooting information calculator.

A fire control device is a device that captures target and artillery positions, weather information, etc., obtains shooting specifications with a computer, and controls the operation of devices related to shooting. Also called fire control system or fire control system.

It is an essential equipment for modern heavy projectile weapons such as tank guns, field artillery, self-propelled artillery or multiple rocket launchers of the Army, naval guns or anti-ship missiles of the Navy, and missiles of the Air Force. This is because the accuracy rate is directly related to combat power, and the act of shooting itself consumes tangible and intangible resources necessary for continuing combat, including ammunition and weapon durability, and furthermore, the physical strength and concentration of operating personnel. . Therefore, an unsuccessful shot simply consumes these resources, and as the frequency of an unsuccessful shot increases, the amount of damage inflicted on the enemy decreases compared to the input resources. In addition, there is a loss of tactical surprise effect due to the failure of the first shot to hit. In addition, the excellent fire control system makes it easy for operators to operate, reducing the accumulation of fatigue, which is a problem during continuous engagement, and prevents the generation of errors that may occur due to mistakes by operators during manual operation. It also has a phosphorus effect.

In this regard, Korean Patent Registration No. 10-1212215 (hereinafter referred to as 'Prior Art 1') discloses a 'method and device for calculating shooting parameters of a gunfire control system'. According to the prior art 1, the gun command calculated at a specific period is time delayed, the gun command to be applied to the gun is calculated based on the previously calculated gun command, and the time delay of the gun command and the specific period are branched into multiple It relates to a firing specification calculation method for securing the differential continuity of a gun command by predicting a differential continuous gun command and applying the predicted gun command to a gun driving server. The prior art 1 is a technology for stably firing a gun command by continuously setting the differential value for each gun command time period, and has a problem in that it does not consider the variables of the shooting environment such as the weather and the type of charge.

In addition, Korean Patent Registration No. 10-2134581 (hereinafter referred to as 'Prior Art 2') discloses a 'drag coefficient calculation device for calculating parameters of gunfire'. Prior Art 2 calculates the drag coefficient of a projectile using a projectile data database in which bullet data is stored in advance and calculates the average value of the final impact point distance, and there is a problem in that the measured value of the actual shooting environment and the characteristics of the charge are not considered.

The firing specification calculation system of the projectile of the present invention is not only the shooting specification in the operation of the projectile that needs to accurately hit the target, but also the characteristics of various types of projectiles, for example, the type of charge and the corresponding range of shooting, and the actual firing of the projectile It relates to a shooting specification calculation system for a projectile that accurately calculates the target impact point of the projectile using environmental measurements so that it can be hit. obtained, the initial prediction range with high reliability was set to minimize errors that could occur in the system in advance, and various actual external environmental conditions, such as weather information, battery location, target location, type of ammunition or type of charge etc. are applied to minimize errors caused by external factors, and to mutually verify the results of calculation of firing parameters and ballistics in each repetition of the algorithm for obtaining the launch angle, thereby minimizing exceptions that may occur during the calculation process. It relates to a calculation system and a method for calculating shooting parameters of a projectile using the same.

According to the conventional method, in order to predict the launch angle according to the range upon impact of the projectile, the expected launch angle is calculated using a predictive model, and then the projectile is fired in a way that is roughly corrected in the form of the expected range. There were many factors that could cause errors in time.

The schematic configuration of the shooting data calculation system of the present invention for impacting a projectile to a target is shown in FIG. 1. As shown in FIG. 1, the shooting data calculation system of the present invention is composed of an input control unit 10, a ballistic calculation unit 20, a shooting data calculation unit 30, and an output control unit 40.

The input control unit 10 acquires shooting specifications and shooting environment measurement values according to a shooting mission execution command. In the present invention, shooting specifications are information necessary for shooting a projectile, and may be any one or more of the type of gun barrel, the type of charge, the type of fuse, and the type of ammunition. In the present invention, shooting specifications are information about basic matters for shooting a projectile, and may include basic shooting specifications not mentioned in this specification.

In addition, in the present invention, the shooting environment measurement is any one or more of the weather information at the time of shooting, the location of the battery for launching the projectile, the target location of the target, the type of ammunition used in the projectile, and the type of charge used inside the ammunition. can In the present invention, the shooting environment measurement includes various information on the shooting environment of the projectile, and may include basic shooting environment measurement values not mentioned herein.

When a command to perform a shooting mission is received, shooting specifications for a projectile and a target are input to the input control unit 10, a shooting environment is measured at the time of shooting, and information about this is input. In this way, the input control unit 10 to which shooting data and shooting environment measurement values are input stores this information and shares it with the ballistic calculation unit 20 and the shooting data calculation unit 30 to be described later.

The ballistic calculation unit 20 is interlocked with the input control unit 10, and selectively collects information on shooting specifications and shooting environment measurement values acquired through the input control unit 10, and within a specific range of the projectile launched to the final target point. Based on the target range, the estimated launch angle and estimated range are calculated. The ballistic calculation unit 20 may obtain the expected launch angle by extracting a characteristic range of the projectile impact range using the charge selection table shown in FIG. 2 and the launch angle characteristics of the projectile range shown in FIG. 3 .

In the case of a projectile requiring shooting specifications, there is a table for each type of gun barrel, charge type, fuse type, and ammunition type. In this way, a table showing how much effective range of range a projectile has for each charge is called a charge selection table, which is schematically shown in FIG. 2. In the present invention, in order to more accurately land the projectile on the target target, the trajectory calculation unit 20 uses the characteristics of the projectile, such as the type of ammunition and the type of charge. Therefore, in order to accurately predict the range according to the type of charge in the ballistic calculator 20, the charge selection table is used in the present invention. The charge selection table shown in FIG. 2 basically shows ranges of the minimum range and the maximum range for each charge.

In addition, the minimum and maximum ranges under given conditions are adjusted according to the launch angle of the gun barrel (QE: Quadrant Elevation) as shown in FIG.

The ballistic calculation unit 20 is linked with the shooting specification calculation unit 30, receives input of the range of the projectile and the operating range of the launch angle, and the range according to the type of charge, and overlaps them based on the range of the range, as shown in FIG. A ballistic calculation value is output by calculating the impact point of the projectile. That is, an effective range for obtaining a desired range can be obtained by selecting the type of charge and adjusting the launch angle of the corresponding projectile through a graph of launch angle and range according to the type of charge.

The shooting specification calculator 30 calculates final information for hitting a target. Specifically, as shown in FIG. 5, the shooting specification calculation unit 30 may be composed of an initial prediction block 31 and a correction block 32. The initial prediction block 31 calculates the impact point of the projectile based on shooting data and shooting environment measurements input through the input control unit 10 and outputs an initial calculation value.

In addition, the correction block 32 receives an initial calculation value from the initial prediction block 31 and is interlocked with the ballistic calculation unit 20 to exchange the ballistic calculation value calculated in the ballistic calculation unit 20 with the initial calculation value. Thus, the error between the initial calculation value and the ballistic calculation value converges to the optimal solution and outputs the final calculation value. Therefore, a reliable and robust shooting data calculation result can be obtained by a method in which the shooting data calculation unit 30 and the ballistic calculation unit 20 mutually verify each other.

Finally, the output control unit 40 outputs the value calculated by the firing specification calculation module to provide the specification for the firing command of the projectile. The output control unit 40 may receive the final calculation value of the shooting specification calculation unit 30 and output one or more of the square of the projectile, the loading amount of the fuse, the shooting azimuth, the estimated range, and the firing angle.

In the present invention, the method of calculating shooting specifications using the shooting specification calculation system for impacting a projectile with a target target includes an input step, a trajectory calculation step, a final calculation step, and an output step, as shown in FIG. consists of including In addition, FIG. 7 schematically shows the algorithm of the shooting specification calculation method of the present invention.

The information input in this way is controlled in a predetermined system to set the initial environment for operation and to form a data structure.

When the input step (S10) is completed, the ballistic calculation step (S20) of selectively collecting the input information and calculating the impact point of the projectile by receiving input of the range of the projectile, operating range of the launch angle, and range according to the type of charge is performed. do. The ballistic calculation step (S20) includes loading the data formed in the input step (S10) and updating the data based on the input data. In addition, calculations are performed to extract the projected range of impact and the specific range of impact. At this time, an estimated launch angle and an estimated range based on a target range within a specific range are calculated based on the input type of charge and range data according to the type of charge. This is based on the launch angle for accurate hitting the target point according to the type of charge of the projectile used at the time and the estimated range based on the launch angle using the charge selection table shown in FIGS. can be calculated.

Next, the ballistic calculation value calculated in the above-described ballistic calculation step (S20) is obtained, shooting specifications and shooting environment measurement information are added to calculate the range of the impact point of the projectile, and calculation is performed in the ballistic calculation step (S20). The final calculation step (S30) of converging the error with the calculated value to the optimal solution and drawing the final calculation value is performed.

In the final calculation step (S30), the initial target hitting point is calculated using the shooting data and shooting environment measurements, and then the calculated ballistic calculation value is compared and exchanged, and the error between them is converged to the optimal solution to obtain the final calculation value. will output Thus, the final calculation value obtained by mutual exchange and convergence with the ballistic calculation value becomes the final result of the shooting specification calculation of the present invention.

As shown in FIG. 7, when the error between the ballistic calculation value obtained in the ballistic calculation step (S20) and the launch angle based on the target range and the estimated range within the specific range obtained in the final calculation step (S30) are out of the usage error range. In this case, the specific range is readjusted and the estimated launch angle and the estimated range are calculated again. By performing this process repeatedly, the final calculation value is output when the error of the launch angle based on the target range and the estimated range within a specific range is narrowed within the usage error range.

Therefore, a reliable result can be obtained by obtaining a final result with minimized errors by a method in which the calculated values of ballistic calculations, shooting specifications, and shooting environment measurements are mutually verified.

Finally, an output step (S40) of receiving the final calculation value calculated in the above-described final calculation step (S30) and outputting any one or more of the angle of the projectile, the loading amount of the fuse, the shooting azimuth, the estimated range, and the firing angle is performed. Hitting accuracy can be improved by using the estimated launch angle and estimated range based on the target range within the final specific range obtained through the output step (S40) as data for impact of the projectile.
