Abstract

PURPOSE:To improve the power of the nose and to improve the directivity by selecting a plurality of detonators based on the distance and the direction of a detected target, and concentrating it at shot bullet piece. CONSTITUTION:A nose 10 detects the distance and the direction of a target by a sensor 12 for detecting the target, and outputs its detection signal to a controller. The controller selects a shot bullet piece according to an input signal regarding the direction from the sensor 12. The piece is disposed on a line segment OT for connecting the center O of the nose to the target T, and an angle theta between a line segment for connecting the selected piece and each detonator and the segment OT and a distance D between the piece and the detonator based on the diameter of the arraying circle of the detonators are obtained. The controller decides the operating order of the detonators according to the magnitude of the next angle theta. The time delay of the two detonators is calculated by dividing the difference of the distances D between both the detonators by the burning speed of bursting charge and a detonation signal is sent to a detonator initially at a detonating point. Then, the piece is strongly shot in a directed direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detonation control device for a warhead mounted on a flying body or the like, and particularly for a directional warhead.

[0002]

2. Description of the Related Art An example of a conventional warhead is shown in FIG. This warhead 20 has a cylindrical shape, is filled with an explosive charge 21, and has a detonator, that is, a detonator 22 in the center thereof. When the detonator 22 ignites, explosive charge 21
The detonation wave spreads radially and acts on the shell 30, which causes the pieces 23 to be uniformly scattered in the radial direction over the entire circumference.

However, when such a warhead is used in a flying object, the bullets are uniformly scattered in the radial direction over the entire circumference, so that the power of the warhead is effectively exerted on the target. It was difficult to do.

Therefore, there has been proposed a warhead in which a detonator is arranged at an eccentric position so that more burst energy is given to a specific projectile piece, thereby giving a directivity. FIG. 7 shows an example thereof. According to this, a plurality of detonators 24, 25, ... Are arranged at eccentric positions, and an initiation signal is supplied to one of the detonators 24. In this case, more explosive energy is given to the projecting piece 26 on the side where the explosive charge 21 is larger than the detonator 24, and the projecting piece 26 flies in the direction of arrow A.

Further, in order to improve the directivity, a warhead has been proposed in which a plurality of detonators are ignited at the same time, and the generated detonation waves are collided with each other, whereby the burst energy is concentrated on the projectile. This is shown in FIG. Two detonators 27,
When 27 'fires simultaneously, two detonations 28, 28'
Occur at the same time. These detonation waves collide as shown in FIG. 8, and due to this collision concentration, the bullets 29 are ejected toward the target at a high initial velocity. According to this, compared with the central detonation shown in FIG. 6, it is expected that the power of the projectile will be about 1.5 times the initial velocity and about twice the energy.

FIG. 4 is a perspective view showing an example of the collision type warhead, and FIG. 5 is a diagram showing the relationship between the detonator and the target in the warhead. The warhead 30 has four detonators 31 to 34 arranged at equal intervals on the circumference of the explosive charge. In FIG. 5, ± 2 with respect to the straight line passing through the center O of the detonator 31 and the array circle of the detonator
When the target is within the range O1 of 2.5 °, only the detonator 31 operates, and the range O2 of ± 22.5 ° with respect to the straight line passing through the center O of the detonator arrangement circle and the middle of the detonator 31 and 32. When there is a target inside, the detonator 31 and the detonator 32 are operated simultaneously.

[0007]

In the conventional collision type warhead 30 described above, for example, when the target T is in the direction of the straight line passing through the points B and O in FIG. 5, the distance D to the point B with respect to the detonator 31 and the detonator 32. , D'are different. Therefore, when two detonators are simultaneously operated, two detonation waves arrive at the bullet at point B with a time shift. That is, the detonation wave of the detonator 31 having a short distance reaches the projectile first, the projectile is ejected by the detonation wave, and the detonation wave of the detonator 32 having a long distance is emitted after the projectile is ejected. Reach B. Therefore, the collision of the detonation wave does not occur in the ejected projectile, so that the burst energy is not concentrated on the intended ejected projectile, and as a result, it is difficult to obtain the desired warhead power.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art and provides an initiation control device for a warhead which has improved power of the warhead and high directivity as compared with the conventional warhead. .

[0009]

The detonation control device of the present invention is provided with a warhead having a rotary body shape and filled with an explosive charge, a target detection means for detecting a target, and a circumferentially arranged explosive charge. A detonation control device for a directional warhead comprising a plurality of detonation devices and detonation control devices for controlling these detonation devices, comprising: a) selecting an ejecting piece according to an output signal of the target detecting means; b. ) The angle between the line segment OT connecting the center O of the warhead and the target T and the line segment connecting the ejecting piece and the detonator, and the diameter of the arrangement circle of the detonating device, the distance between the ejecting piece and the detoning device C) The actuation order of the detonator is determined according to the size of the angle θ, the detonator having the smallest angle θ is operated first, and after the predetermined time has elapsed, the detonator having the second smallest angle θ is selected. It is then activated, thus making it possible to The detonators are sequentially operated with a time delay to the corner detonators, and d) the time delay between the two detonators operating with a time delay is set to the distance D between the two detonators. It is characterized in that it is configured to be calculated by dividing the difference by the burning rate of the explosive charge.

The target detecting means can detect the distance and direction of the target, for example. Further, the detonation control device controls the operation of the detonation device as described below based on the input signal sent from the target detecting means.

In order to eject a bullet piece toward the target,
The ejection bullet is selected according to the output signal of the target detecting means.
This ejected piece is a line segment O connecting the center O of the warhead and the target T.
It is on T. In FIG. 3, the shell portion located at the point B corresponds to this.

Next, the distance D between the ejecting piece and the detonator is obtained from the angle θ formed by the line segment connecting the ejecting piece and the detonator and the line segment OT and the diameter of the array circle of the detonator. . For example, in FIG. 3, the diameter of the array circle of the detonator is AB, the detonation point of the detonator on the circumference of the circle is 1, and the angle α formed by connecting the detonation point 1 and the point A is a right angle. Therefore, the distance D1 of the detonator at the detonation point 1 is obtained by D1 = AB · cos θ1.

Further, the detonation control device determines the operating order of the detonation device according to the size of the angle θ. From the above equation, the smaller the θ is, the larger the distance D is. Therefore, the detonator having the smallest angle θ, that is, the detonator having the largest distance to the ejecting piece is first operated, and the angle θ is set to two after a predetermined time elapses. The second smallest detonator is then actuated, thus activating the detonator sequentially from the smallest angle detonator to the larger angle detonator with a time delay. This time delay is calculated as follows.

That is, the time delay between the two initiators operating with a time delay is calculated by dividing the difference in the distance D between the two initiators by the combustion speed of the explosive charge. As a result, the difference in arrival time based on the difference in distance is adjusted, and the detonation waves emitted from the respective detonators simultaneously reach the ejecting projectiles and concentrate the burst energy on the projectiles. Therefore, the bullet pieces are strongly ejected in the pointing direction.

The calculation and generation of the delay time is performed by electric (electronic)
This can be performed by the formula calculation distribution circuit. This circuit operates to calculate the delay time, generate an electrical signal according to the calculated delay time, and send it to a predetermined detonator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic view of a projectile 40 carrying a directional warhead having a detonation control device according to the present invention.
The flying body 40 has stabilizing wings 41 at the rear portion, and the main directional warhead 10 is arranged at the main body portion 42. FIG. 2 is a configuration diagram of the directional warhead 10. The warhead 10 has a cylindrical shape and is filled with an explosive charge 11 inside. Eight detonators are arranged on the outer periphery of the explosive charge 11 at equal intervals on the circumference, and the positions of the detonators are 1, 2, 3, ... 8 as initiation points as shown in FIG. Indicated by the numbers.

The warhead 10 calculates a delay time based on a target detection device for detecting a target, that is, a sensor 12 and an input signal from the sensor 12, and sequentially detonates a predetermined detonator according to the delay time. A control device including a delay time calculation and distribution circuit 13 for outputting
The sensor 12 detects the distance and the direction of the target and outputs the detection signal to the control device. The control device selects a projectile piece according to the direction signal from the sensor 12.
This ejected piece is a line segment O connecting the center O of the warhead and the target T.
This corresponds to the piece FB on the T and at the position indicated by the point B in FIG. Next, the control device makes the angles θ1, θ2, θ3, ... Between the line segment connecting the selected ejection piece, ie, the piece FB and each detonator and the line segment OT, and the array circle of the detonator. The distance Dn between the projectile FB and each detonator is determined by Dn = AB · cos θn (n = 1, 2, 3, ...) Based on the diameter AB of It should be noted that this value can be modified by the distance from the warhead surface of the detonation point, the time characteristic peculiar to the detonator, and the like.

The control device then determines the operating order of the detonator according to the magnitude of the angle θ. In this case, θ1 <θ2
Since <θ3 ..., the detonator at the detonation point 1 operates first, and the detonators at the detonation points 2 and 3 operate sequentially.

The delay time calculation and distribution circuit 13 in the control device calculates the time delay between the two detonators operating with a time delay and the difference in the distance D between the two detonators, and the explosive combustion. Calculated by dividing by the speed. After the detonator at the detonation point 1 first operates, the detonator at the detonation point 2 operates after the delay time t2. Detonator with blast point 1 and shell FB
The distance between them is D1, and the distance between the detonator at the detonation point 2 and the projectile FB is D
2. If the burning rate of explosive charge is V, this t2 is obtained by t2 = (D1-D2) / V.

After the detonator at the detonation point 1 is activated, the detonator at the detonation point 3 is activated after a delay time t3. This delay time t3
Let D3 be the distance between the detonator at the detonation point 3 and the piece FB,
Similarly, it is obtained from t3 = (D1-D3) / V. In the same manner, the delay time t4 and thereafter are obtained.

The delay time calculation and distribution circuit 13 first sends a detonation signal to the detonator at the detonation point 1. As a result, the detonator ignites, and a detonation wave is generated from the detonation point 1 due to the ignition of the detonator. This roar wave advances toward the piece FB. Next, the circuit 13 sets the initiation point 1 according to the calculated delay time.
A detonation signal is sent to the detonator at the detonation point 2 t2 hours after the detonator is activated. As a result, the detonator ignites and a detonation wave is generated, and this detonation wave advances toward the projectile FB. In this way, the detonation wave generated at each detonation point with a delay time,
At the same time, it reaches the projectile FB, where it collides and concentrates and acts on the projectile FB. Due to the concentrated burst energy, the bullet FB is
It is strongly emitted in the pointing direction with a high initial velocity.

[0023]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the detonation waves generated at each initiation point can reach the ejecting bullets at the same time. As a result, the expelled projectile is strongly expelled in the pointing direction with a high initial velocity due to the concentrated burst energy. Therefore, according to the present invention, the power of the warhead can be maximized and the directivity of the warhead can be significantly improved without increasing the volume and weight of the warhead.
