2. Description of the Related Art In shooting training with a machine gun, a machine gun, etc. provided in an aircraft, a series of shots is usually made at a target standing on the ground. This target is made with a canvas, for example, approximately 5m
It is × 5 m square and the center is provided with a target. A bullet mark remains on the canvas due to a series of shots. During the shooting training, it is not possible to measure the bullet hole by approaching the target for safety. Therefore, the hit state is visually judged by observing the bullet hole from a distant place with an endoscope such as binoculars.

[0003]

It is extremely skillful to visually recognize the bullet holes left on the target by a series of shots and judge the effect of the shot. And the judgment varies depending on the person making the judgment. Therefore, it is desired to obtain the objectivity of the judgment of the degree of hit. However, when the judgment result is communicated to the shooter on board the aircraft or the instructor on board, only the outline can be conveyed.

Further, when a curtain-like target such as a canvas is targeted, the landing state can be known only during a series of shots to the target, and from the second shot, the landing state can be used as the target. Is difficult to distinguish.

It is only a single continuous shot that the target made of a canvas can detect the state of impact of a series of shots.
A target made of yanbas needs a yanbas, a frame to stretch it and a member for supporting it on the ground. For example, 100k
Since it is heavy with g, it takes labor to replace it. Also, it is not possible to perform shooting training while changing targets.

[0006] It is an object of the present invention to provide a continuous fire evaluation device and a continuous fire training system capable of displaying, as an image, a landing state of continuous shooting from a moving object such as an aircraft to a target on the ground or at sea.

Another object of the present invention is to provide a continuous fire evaluation device and a continuous fire training system capable of displaying a landing state continuously fired from a moving body such as an aircraft on a target on the ground or on the sea by a statistical index.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the entire blaze training system. Moving objects such as aircraft in flight (hereinafter referred to as aircraft)
The bullets continuously fired from the machine gun 2 of No. 1 toward the strafing target (hereinafter referred to as the target) 3 on the ground are successively detected by the bullet passing position detecting device 4 provided in front of the target 3. The signal obtained by the bullet passage position detection device 4 is sent to the landing analysis device 5 placed on the ground by wire or wireless communication. The landing analysis device 5 calculates the passing position of each bullet fired in front of the target 3 and displays the calculation result as an image. At the same time, the calculation result is sent to the aircraft 1 by the wireless communication means 6 having the transmitter 6a and the receiver 6b. The display from the receiver 6b is displayed on the display 8 via the interface 7 provided in the aircraft 1, respectively. In addition,
The impact analysis device 5 calculates and outputs the impact result to facilitate the determination of the fire result. The impact analysis device 5 is placed on the ground or at the sea as will be described later, has a display itself, and can be operated by a keyboard.

FIG. 2 shows a bullet passing position detecting device 4. Although FIG. 2 shows the target 3 of a curtain made of a canvas or the like which is erected on the ground, the target 3 may be provided directly on the ground or along the ground. This can reduce the effort of standing a heavy canvas target. In either case, the images seen by the shooter of the aircraft 1 are the same so that the images seen by the shooter do not change. Therefore, the target provided on the ground is long. Therefore, when the target is provided on the ground, the target length may be shortened by obliquely providing the target on the inclined surface. In addition, the target along the ground can be painted only, and the preparation and withdrawal of the target itself can be saved. Sound pressure sensors A, O, B, and C are disposed immediately in front of the target 3 when viewed in the flight direction of the bullet in the trajectory. Sound pressure sensor A, O,
Bs are arranged in the horizontal direction at regular intervals on a plane substantially orthogonal to the trajectory 9. Sound pressure sensor C is sound pressure sensor O
It is arranged between the sound pressure sensor O and the target 3 at a position parallel to the trajectory 9. Each sound pressure sensor A, O, B,
When the bullet passes over the sound pressure sensors A, O, B and C, C detects a shock wave generated from the flight of the bullet.

When an aircraft shoots a target on the ground or at sea, the aircraft is flying at a high speed, and therefore the distance to the target changes greatly even if the timing of shooting is slightly different. As the distance changes, so does the speed of the bullet. Therefore, the sound pressure sensor C is provided, and the time difference ΔT _c between the time when the sound pressure sensor O detects the shock wave generated by the flight of the bullet and the time when the sound pressure sensor C detects the shock wave is calculated. Since the distance between the sound pressure sensors O and C is constant and the distance between the trajectory 9 and each of the sound pressure sensors O and C is equal, it is possible to obtain a bullet velocity passing over the sound pressure sensors O and C.

Since the angle of the Mach cone of the shock wave differs depending on the velocity of the bullet, even if the bullet passing positions are the same, if the bullet velocity is different, there is a difference in the time for the shock wave to reach the sound pressure sensors A, O, B. Therefore, the time difference between the arrival time of the shock wave at the sound pressure sensor O and the arrival time of the shock wave at the sound pressure sensors A and B also varies depending on the bullet velocity. Therefore, as described above, the bullet velocity is obtained using the sound pressure sensors O and C, and the detection of the bullet passing position is made accurate.

Bullet passing position 9 on the sound pressure sensors A, O, B
“A” is obtained from the time differences ΔTa and ΔTb at which the sound pressure sensors A and B and the sound pressure sensor O receive the shock wave and the bullet velocity.

As shown in FIG. 3, A9a-O9a = const. Where the time difference ΔTa is constant. Curve 12 that satisfies
And the time difference ΔTb becomes constant, B9a−O9a = con
st. The bullet passing position (one point on the trajectory 9a) is obtained as the intersection of the curves 11 that satisfy

FIG. 4 shows an example of a time difference when the sound pressure sensors A and O detect a shock wave. The vertical axis represents the magnitude of the shock wave and the horizontal axis represents the time of occurrence of the shock wave. In this example, the sound pressure sensors A and O
The time difference ΔTa of the time when the shock wave is detected is 470 μse
It is c.

FIG. 5 shows the sound pressure sensor O in the case of continuous shooting.
Indicates a shock wave received by. In FIG. 5, the vertical axis represents the magnitude of the shock wave, and the horizontal axis represents the continuous shooting time. Therefore, the passing position of each bullet in the case of continuous shooting can be obtained without any fluctuations in the time interval of passing the sound pressure sensor O for each bullet that has fired consecutively.

FIG. 6 shows target 3 (31, 32, 33, 34)
The following shows the main part of this system when four are connected in parallel. A bullet passing position detection device 4 (4 attached to the targets 31 to 34)
a, 4b, 4c, 4d) are connected to the central processing unit 12 of the landing analysis device 5. The central processing unit 12 is a calculating means for performing a calculation by receiving a signal from the bullet passing position detecting device 4, for example, a personal computer main body and not shown in the figure cp.
u. It has a memory and so on. The central processing unit 12 has a measurement start function, and by selecting the measurement start or by automatically detecting the shock wave of the first bullet, the signal processing device 14 (14a, 14b, 14c) of the bullet passing position detecting device 4 is automatically performed. , 14d)
Turn on each. In addition, it has a reset function and by selecting reset, it returns to the initial condition and stops.

The central processing unit 12 can adjust the measurement setting conditions. In addition, calibration can be performed at the same time.

The central processing unit 12 calculates the landing position. In this calculation, the signals of the sound pressure sensors A, O, B, and C are landed by using the digital signals sent by AD-converting the time difference obtained by the sound pressure sensors in the signal processing devices 14a, 14b, 14c, and 14d. Calculate position. The principle of calculation of this landing position is as described with reference to FIGS. 2 and 3, and the landing position is calculated for each bullet fired continuously. By using the result of this calculation, it is possible to obtain an image almost equivalent to the image of the target 3, a statistical evaluation value of accuracy of hit, a number of hits, and the like.

The central processing unit 12 can display and print the bullet hole distribution corresponding to the bullet holes of the target 3 on the basis of the calculation result of the landing position. Here, the screen display in the continuous shooting state is performed by the display 15, and the numerical display is performed by the LED display 16. Printing is displayed by the printer 17. Note that printing is also display means, and the output from the central processing unit 12 may be recognized in any way. The record of the measurement data input to the central processing unit 12 is stored in the hard disk 19. The central processing unit manages the measurement data by using the record of the measurement data. Keyboard 18
Selects a display method, takes out from the hard disk 19 to a floppy (registered trademark), MO disk, or the like and saves it. Further, the keyboard 18 is the transmitter 6a shown in FIG.
It is used for the setting that can be displayed on the display 8 on the aircraft 1 via the receiver 6b.

FIG. 7 shows the results obtained by deploying the above-mentioned devices of the present invention on the ground and shooting them continuously toward the target 3. The target 3 is made of a canvas with a width of about 2 m, and has a + target 30 in the center.

FIG. 8 shows the display 15 of the impact analysis device 5.
It is a screen which shows the bullet passing position near the target 3 displayed above. The image of the display 14 shows the width of the target 3 of about 2 m as a dimension line for comparison with the target's bullet holes. Of course, the display 15 is small, such as 10 inches or 15 inches, but it can be seen in a partially enlarged manner. For the sake of explanation, the target 3 and the display 15 are shown as the same size in FIGS. 7 and 8.

Points Q1 to Q24 are displayed on the display 14 in correspondence with the bullet holes P1 to P24 on the target 3. Here, the point Qi (i = 1 ... 24) is the bullet hole Pi (i
= 1. ． ． 24), and the bullet holes Pi and the points Qi almost match each other as shown in FIGS. 7 and 8, and the bullet holes group of the continuous shooting and the point group on the display are well matched. I am doing it.

Various methods can be considered for evaluating the result of the continuous shooting, but as an example, the average value rm and the variance Sr ² are obtained. In FIG. 8, the center of a target 30 ', which is an image on the display 15 of the target 30, is E. The beginning of the first quadrant in FIG. 8 is designated as the original line EX.

The average value rm of the radius vector, the angle θm formed by the average value rm of the radius vector with the original line EX, the variance S _r ^{2 of the} radius vector, etc. are calculated by the central processing unit 12, and the display 15 or the LED. It is displayed on the display 16. Therefore, the communication means 6 can be used as a reference when the shooter or the instructor on the aircraft performs the next series of shots accordingly. Next, the calculation method will be described.

As described above, the bullet holes P1 to P2 of the target 3
4 and the point Q corresponding to each bullet hole on the display 15
According to the experiment, the distributions of 1 to Q24 are in good agreement.

There are various conceivable methods for evaluating continuous shooting, but as an example, an average value and variance based on XY coordinates are obtained. Point Q
When the coordinates of i are xi, yi (i = 1 ... N), the x-coordinate xm and the y-coordinate ym of the average value are: xm = Σxi / n ym = Σyi / n This calculation is performed by the central processing unit 12 and is displayed on the display 15 or the LED display 16.
The XY coordinates of the average value allow the shooter to know how far the aim is horizontally and vertically with respect to the target 30.

Next, when the variance around the average value of n shots is obtained, the variance value Sr ² is Sr ² = 1 / n [Σ {(xi-xm) ² + (yi-ym)
² }]. This allows the shooter to know the degree of concentration of the shot.

On the other hand, the accuracy of hitting the target is a deviation distance, that is, the distance ri (i from the center of the target 30 'to each bullet hole Pi.
=. ． ． Since it is represented by the size of n), it can be evaluated by the standard deviation σ, assuming that this is a normal distribution.
The standard deviation σ is σ = √1 / n {Σ (ri-rm) ² }, which is the upper probability 0.25 of the standard normal probability table.
One method is to use the value of 675σ as the half radius of the hit field to evaluate the accuracy of the hit.

In FIG. 1, the impact analysis device 5 is provided on the ground or at the sea, and the data processed by the communication means 6 as described above is sent to the aircraft 1 and displayed on the display 8. However, it is not limited to this. As another method, the impact analysis device 5 is loaded on the aircraft 1. Then, the digital signal output from the signal processing device 14 of the bullet passing position detecting device 4 is transmitted to the landing analyzing device 5 on the aircraft 1 by the communication means 6 to the signals of the respective sound pressure sensors A, O, B and C. . Then, it is displayed on the display 15 as an image corresponding to the bullet holes Pi (i = 1..24) on the target 30 as already described by the landing analysis device 5. Further, the impact analysis device 5 displays the average value, the variance, the hit rate, etc., of the impact positions, which are evaluation values.

Further, simply, the display 1 is not provided on the aircraft 1, and the average value of the landing positions calculated by the landing or sea landing analysis device 5 by the communication means 6 and the point of the average value seen from the origin E. The direction dispersion of Q _m , the hit rate, etc. may be transmitted by the communication means 6. Also, aircraft 1
It is also possible to install only the printer 17 in the computer and print the result of the continuous shooting from the central processing unit 12 using the communication means 6.

By providing the straffin target directly on the ground surface, it is necessary to handle a heavy target such as setting up the straffin target on the ground with several people.
And the problem that shooting training cannot be done during that time is solved.

In the embodiment, the average value is used as the impact evaluation value, but the mode value may be used.

As described above, the embodiment is a continuous shooting evaluation device for a machine gun 2 or the like, and detects the strafing target 3 and the passing position of each bullet successively fired toward the strafing target 3 near the target. Sound pressure sensors A, O, B, C arranged near the target for

By using the shooting evaluation device,
It is possible to evaluate the effect of continuous fire such as a machine gun. The effect of this rapid fire can be evaluated in real time. The strafing target's bullet hole does not show the state of rapid fire, so unless the target is damaged to the extent that it cannot be seen, the effect of rapid fire can be evaluated even after repeated use.

By displaying the evaluation value, the shooter or the instructor can evaluate the series of shots, and can objectively grasp the effect of the continuous shot, which is conventionally judged by the human sense.

When the target 3 is provided along the ground surface in the above description, it is not necessary to replace the target 3. In addition, since the length of the target 3 in the flight direction of the bullet is greatly increased, the distribution of the bullet holes becomes coarse, and the target 3 can be used for a long time.
