Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shooting simulator used for training shooting weapons, and more particularly to a shooting simulator used for simulating the shooting of a curved firearm that cannot directly look at the shooting target.

[0002]

2. Description of the Related Art Conventionally, as a shooting simulator used for training a shooting weapon, a combination of a laser beam emitter and a light receiver is used for a direct weapon such as a machine gun looking directly at an object to be shot. Are known. This makes it possible to judge the shooting result as if the bullet hits when the side shooting the direct weapon emits a laser beam instead of the actual bullet and the receiver on the shot side receives this laser beam. It is a thing. By using such a shooting simulator, it is possible to perform shooting training without performing live shooting.
It is possible to conduct counter-shooting training that separates the enemy and the ally, which are closer to actual battle.

[0003]

However, the conventional shooting simulator using a laser beam can only be used for shooting training of a direct weapon, such as a machine gun, when the shooting target can be seen directly, that is, the shooting target. It could not be used for shooting training of artillery weapons such as cannons that could not look directly at. Conventionally, there is no shooting simulator for curved weapons, and shooting training for curved weapons can only be performed by live-firing.

A device as shown in Japanese Utility Model Laid-Open No. 56-19858 has also been proposed, but this device is used as a unit position information for evaluating the present position of a unit having a shooting weapon,
Various types of shooting information of shooting weapons, unit status such as degree of protection of units, topographic information such as topography, vegetation, geology, and unit position information are not taken into consideration, so a shooting simulator that can replace actual shooting Could not be used as.

The present invention has been proposed in order to solve the problems of the above-mentioned conventional techniques, and in carrying out the shooting training of a curved weapon such as a cannon which cannot directly look at the shooting target, the real shooting is carried out. It is an object of the present invention to provide a shooting simulation device capable of carrying out an equivalent training without any action.

[0006]

In order to achieve this object, a shooting simulator according to the present invention evaluates the current position of a unit or the like having a shooting weapon, outputs unit position information, and shoots various types of shooting weapons. From the shooting information input means that inputs specifications and outputs shooting specifications information, the impact area of bullets fired by the shooting weapon is calculated from the above-mentioned troop position information and the above-mentioned shooting specifications information, and the degree of protection of the troops. Enter the unit status such as landform information such as topography, vegetation, geology, etc. and the landing status information including the information on the landing area, the unit status and the unit position information, and the preset criteria And a shooting evaluation means for judging the shooting effect of the curved weapon based on the above.

Further, the shooting simulation apparatus according to the present invention inputs the shooting position by inputting the self-position rating unit for rating the current position of a unit having a shooting weapon and outputting unit position information. Firing information input means consisting of a shooting specification input section that outputs original information, and the landing area calculation for calculating the landing area of the bullet fired by the shooting weapon from the above unit position information and the above shooting specification information A unit, a unit status grasping unit that inputs unit status information such as the unit position information and the degree of protection of the unit and outputs unit information, and a terrain condition that outputs pre-stored topographic information such as topography, vegetation, geology, etc. A grasping unit, and a shooting effect determination that determines the shooting effect of a curved weapon based on preset criteria from the landing situation information including information on the landing area, the unit information, and the terrain information. With shooting evaluation means .

First, the basic concept of simulating the shooting of a curved weapon will be described. When shooting a curved weapon, various effects on range and direction (ballistic calculation factors)
2 becomes a trajectory A as shown in FIG. The shooting distance is from the origin S0 to the drop point S1. The bullet fired from the origin S0 reaches the highest point through the ascending arc A1 and reaches the drop point S1 through the descending arc A2. a1 is the vertical projection of the trajectory and a2 is the horizontal projection of the trajectory.

Various effects on the shooting distance include initial velocity, bullet amount,
There are air drag, ballistic coefficient, ballistic temperature, and ballistic vertical wind. The initial velocity can be estimated by a combination of guns, bullets, and propellant charges, and an increase in initial velocity increases the range. The impact of ammunition is
When fired at the same angle and at the same initial velocity, a heavy bullet increases the range of firing compared to a light bullet of the same shape. The air drag is a force acting on the drag center of the bullet in the direction opposite to the movement direction, and an increase in the air drag reduces the shooting distance. Air drag increases with increasing air density, bullet velocity, bullet diameter, and air drag coefficient. Ballistic coefficient is a numerical value representing the ability of a bullet to overcome air resistance. Increasing ballistic air temperature reduces air density, reduces air drag, and increases range. For ballistic longitudinal winds, in the case of headwinds, the range is reduced.

The influence on the direction of the trajectory is drift, cross-wind, and rotation of the earth. With regard to drift, the bullet mutates from the shooting surface to the direction of rotation (right) during flight due to the effects of its rotation, aerodynamic drag and gravity. The impact of a ballistic crosswind is that the bullet is displaced to the left by the crosswind from the right. The impact of the rotation of the earth is that the bullet deviates from the target due to the rotation of the earth.

In the present invention, among the above-mentioned ballistic calculation factors, types of firearms (guns) that can be set or obtained on the curved firearm side, bullet types, launch charges, firing angles, bullet numbers (ammunition amount),
The shooting specifications such as wind direction and wind force are manually input from the shooting specification input unit, and the impact area (the drop point of the bullet) is calculated in the impact area grasping unit based on these specifications. Further, when a large number of bullets are continuously fired under the same gun and under the same condition, these shots are not attached to the same point but are dispersed and attached to an area due to various causes. Since this distribution follows a normal distribution, the landing area grasping section also calculates the landing area in consideration of this dispersion.

In the shooting effect determination unit, the position of the unit, dispersion,
Based on the degree of protection (building), the landing area and the topographical conditions, the damage to personnel and equipment is calculated based on the standards obtained in advance. As a standard that has been obtained in advance,
For example, there is data indicating the probability of destruction of personnel and various equipment when a plurality of bullets hit and land within a certain range (100 m square). The probability of destruction of personnel and equipment can be calculated from this data based on the information on the landing area including the dispersion from the landing area grasping unit, the position of the unit from the unit situation grasping unit, and the degree of dispersion. In addition, as the criteria (data) obtained in advance, the probability of destruction increases according to the amount of ammo, and even with the same amount of ammunition, characteristics such as the probability of destruction differ between personnel and various equipment are also entered. ing.

Next, based on the topographical information from the topographical condition grasping part and the information on the degree of protection (building) from the troop condition grasping part, the effect data of the topography (whether the landform is flat or mountainous, The effect of the topography and the effect of the castle is calculated based on whether the personnel deployed to the terrain are standing or prone, and the effect of the castle (whether the castle is a trench, takotsubo, or underground moat). First, as the influence of the terrain, the probability of destruction corresponding to each terrain classification is obtained by multiplying the value obtained from the amount of missed bombardment (number) versus the probability of destruction (munition type: 250 kgGP) by the regional coefficient. As a result of the construction of the castle, the probability of destruction of the target, which depends on the degree of construction, is
It is calculated by multiplying the value obtained from 0 kgGP) by the construction factor. In this way, the overall probability of destruction is calculated, taking into consideration the topography and castle construction. Randomly destroyed according to this destruction probability,
Determine non-destructive.
