Abstract

PROBLEM TO BE SOLVED: To prevent the nonuniform scattering of a shell splinter due to an outer cylinder existing at the outside and to effectively break a target by breaking the outer cylinder by some means before bursting charge explodes and the shell splinter is scattered. SOLUTION: Although a sub-booster 18 and a booster 15 begin to be simultaneously burned when a detonation 14 is ignited, the combustion of the sub- booster 18 where flame quickly spreads is terminated first, the ignition of a sub-booster 17 is made first, and a sub-bursting charge 16 is exploded. At this time, since a shell 10 has firm arch structure and a bursting charge 11 before explosion is loaded inside, the energy of the sub-bursting charge 16 with small explosion force cannot press them. However, an outer cylinder 9 is thin, and no obstacles exist outside, thus easily resulting in explosion toward the outside. Immediately after this, although flame being transferred in the booster 15 initiates a booster 13, and the bursting charge 11 is exploded, the outer cylinder 9 has already been broken and scattered, thus uniformly scattering a fragment 6 without any resistance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projectile warhead used for anti-aircraft weapons and the like.

[0002]

2. Description of the Related Art Conventionally, a situation in which a flying object is used as an anti-aircraft weapon is as shown in FIG.
In FIG. 5, the flying object 2 is fired in front of, that is, from the right to the left, and attempts to intercept the opposing aircraft 1 invading from the left to the right. The flying object 2 includes a tip 3 and a tail 4, and a warhead 5 interposed therebetween. If the aim is ideal, the flying object 2 collides directly with the opponent aircraft 1, but usually passes slightly apart due to an error. The warhead 5 explodes at the moment when the flying object 2 passes the counterpart aircraft 1, and the scattered fragments 6 penetrate the counterpart aircraft 1 and shoot it down.

[0003] Next, the warhead 5 incorporated in this flying object
The detailed structure of will be described. FIG. 6 is a cross-sectional view showing the configuration of a conventional warhead of a flying object. The front and rear ends of a warhead 5 sandwiched between a tip 3 and a tail 4 are respectively a disk-shaped front flange 7 and a rear flange 8. A cylindrical outer cylinder 9 is attached so as to form an outer shell of the flying object. Inside the outer cylinder 9, there is a shell 10 for penetrating and destroying a target, which is composed of a large number of pieces 6 made of, for example, a hard metal, which are integrally formed into a spherical shell or barrel shape. It was done. A filling 11 made of a high-performance explosive or the like is filled so as to fill the inside thereof.
A booster 13 for exploding 1 is incorporated. At the center of the front flange 7 is an explosive 14 for detonating the warhead 5, and an explosive 15 is incorporated so as to connect this to the booster 13.

Next, the operation will be described. When the flying object configured as described above is fired at the opponent aircraft and is about to pass each other at a short distance, when the command to detonate the warhead is issued, first, the explosive 14 is ignited. The flame is transmitted to the booster 13 through the explosive charge 15, and the booster 13 detonates and the explosive 11 explodes, whereby the integrated shell 10 is separated into individual pieces 6, and is separated. It pierces the cylinder 9 and scatters radially around the booster 13 to penetrate and shoot down the target aircraft body.

[0005]

Since the conventional warhead is constructed as described above, the bullet 6 cannot be scattered freely without first breaking through the outer cylinder 9. The outer cylinder 9 is a smooth cylinder without any particular discontinuity, and when the warhead detonates, the bullet 6 starts to tear from the portion that first collided from the inside,
After that it is usual to spread so that it can be broken,
Since there is a slight individual difference between the bullets 6, the way of breaking them is not completely uniform, especially in the circumferential direction. as a result,
The bullet 6 that would otherwise scatter uniformly in the circumferential direction without the outer cylinder 9 is scattered non-uniformly by receiving or not receiving resistance in the outer cylinder 9. If the target is limited to a relatively large aircraft, as in the past, as long as the warhead detonates at a close distance, many bullets 6 can hit the opponent and be destroyed and shot down. The scattering did not have to be particularly uniform. However, in recent years, when targets to be shot down are included in small flying objects such as cruise missiles and anti-ship missiles, the targets are so small that they pass through between the flying fragments 6 and detonate at close range. Despite having done so, there was a fear that they could not be shot down. For this reason, the size and number of bullets 6 are carefully set so that the flying fragments fill the space with just the right density, but this has been the case. If the particles are scattered non-uniformly, an area where the density of the bullets 6 is low partially occurs, and there is a possibility that the target may pass through without damage. The outer cylinder 9 is made of a thin material so as not to disturb the movement of the projectile as much as possible. However, the outer shell of the flying object needs to have a minimum strength. When the aerodynamic load received increases, it cannot be made too thin. Therefore,
The outer cylinder 9 hinders the free scattering of the projectiles 6, and the tendency of the shells to be scattered non-uniformly has increased.

On the other hand, as shown in FIG. 7, the shell 10 is not a collection of bullets, and there is a conventional warhead which is formed as an integral cylinder with cuts 21 in the vertical and horizontal directions. This is configured so that when detonated, the shell 10 is torn off from the notch 21 into individual pieces, and since the shell 10 also serves as the outer shell of the flying object, no outer cylinder is required. Thus, there is no possibility that the above-mentioned bullets are scattered unevenly. However, in order to break the shell 10 according to the setting with the energy of the explosion, the cut 21 must be carved very accurately, and the scattering tends to be uneven due to the processing accuracy. In addition, since the shell 10 is inevitably formed in a cylindrical shape and is difficult to be formed in a barrel shape as shown in FIG. 5, it is also difficult to scatter the bullets in an ideal radial shape. Furthermore, in order to enhance the effect of penetrating the target, it is desirable to use a particularly hard material such as tungsten, but a more viscous material is preferable for the structural member that is the outer shell of the flying object. Is not easy. As described above, the conventional warhead has a problem in that the scattering of the projectiles tends to be non-uniform, and if this is avoided, another problem occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and is intended to prevent the projectiles from being scattered unevenly even if there is an outer cylinder outside. The warhead is configured to destroy and remove the outer cylinder immediately before the detonation.

[0008]

According to a first aspect of the present invention, there is provided a warhead in which an outer cylinder is destroyed by any means before explosive explosion explodes and splinters scatter.

A warhead according to a second aspect of the present invention is provided with a secondary drug and a secondary booster in the space between the outer cylinder and the shell. It is designed so that the medicine explodes.

The warhead according to the third aspect of the present invention is provided with a separate high-pressure gas generator. This generator operates before the explosive explodes and the scattered pieces are scattered, and the generated high-pressure gas is transferred to the outer cylinder. It is designed to blow into the space between the shell and the shell.

The warhead according to a fourth aspect of the present invention is provided with a sub-drug in a space between the outer cylinder and the shell, and a number of sub-boosters are arranged along the inner peripheral surface near the center of the front and rear of the outer cylinder. The secondary drug is designed to explode before the drug explodes and the fragments are scattered.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. 1 is a cross-sectional view for explaining the configuration of the first embodiment of the present invention,
A sub-pharmaceutical 16 having a low explosive power is loaded in a cylindrical space between the outer cylinder 9 and the sub-booster 9, and a sub-booster 17 for detonating the sub-pharmaceutical 16 is mounted at the front end thereof. The auxiliary booster 17 and the priming 14 are connected by a front priming 18 penetrating the inside of the front flange 7.
Is designed such that the speed at which the flame propagates is slightly faster than the explosive charge 15. Other configurations are the same as those of the conventional warhead shown in FIG.

The operation of the first embodiment of the present invention will be described with reference to FIG. When the primary explosive 14 is ignited to detonate the warhead, the secondary explosive 18 and the primary explosive 15 start burning at the same time. Booster 17 detonates first and secondary drug 1
6 explodes. Since the shell 10 has a kind of solid arch structure and the inside thereof is filled with the medicine 11 before explosion, the energy of the auxiliary medicine 16 having a small explosive power cannot crush them. However, the outer cylinder 9 is simply a thin-walled cylinder that is not particularly reinforced, and easily ruptures outward without any obstacles on the outside. Immediately thereafter, the flame that has traveled through the explosive charge 15 reaches the booster 13, and the explosive 11 explodes. At this time, since the outer cylinder 9 has already been destroyed and scattered, the bullet 6 receives no resistance. It can be scattered freely and uniformly.

Embodiment 2 FIG. In the first embodiment, an auxiliary cylinder is used to destroy the outer cylinder. However, since the outer cylinder is often thin-walled, the outer cylinder can be destroyed not by explosive energy of explosives but by the pressure of high-pressure gas and internal pressure. FIG. 2 shows such an embodiment, in which a gas generator 19 is placed outside the front flange 7, and a pipe 20 extending therefrom is connected to a space inside the outer cylinder 9. When operating the warhead, first, the gas generator 19 is operated to generate high-pressure gas, and the high-pressure gas is filled in the space inside the outer cylinder 9 through the pipe 20. The outer cylinder 9 is destroyed by the internal pressure of the high-pressure gas, and immediately after that, the drug 11 explodes and the bullet 6
Scatters uniformly without resistance.

Embodiment 3 It is empirically known that, when the outer cylinder is to be broken by the internal pressure as in the second embodiment, the hoop stress causes a certain portion on the circumference to be broken while being torn in the vertical direction. If one location breaks, the internal pressure escapes therefrom, and the projectiles may scatter before the outer cylinder on the opposite side is completely scattered, making it impossible to scatter uniformly around the circumference. Also in the first embodiment, since the debris broken by the outer cylinder is in the form of a thin plate, the debris is easily decelerated by air resistance, and the scattered fragments tend to catch up later, and also have an uneven resistance. There is a risk of receiving it. In the third embodiment shown in FIG. 3, a plurality of sub-boosters 17 are arranged along the center inner periphery of the outer cylinder 9, and sub-explosives 18 are connected to each of them to explode the sub-explosives 16 at the same time. I have.

The operation of the warhead shown in FIG. 3 will be described. When operating, first, the auxiliary boosters 17 arranged circumferentially detonate at the same time, and the auxiliary drug 16 explodes from the center toward the front and rear ends. As a result, as shown in FIG. 4, the outer cylinder 9 is divided back and forth along the circumference at the central portion, and is then wrapped around in the front-rear direction as the secondary drug 16 explodes. Therefore, there is no danger that the destroyed debris will remain at a specific position on the circumference, and there will be no uneven floating in the space where the projectiles 6 are about to scatter. Therefore, there is no risk of receiving non-uniform resistance when the projectile 6 attempts to fly immediately thereafter.

[0017]

According to the first and second aspects of the present invention, even in a warhead having an outer cylinder on the outer side of a shell, it is possible to prevent a projectile from being scattered unevenly due to being hindered by the outer cylinder, and to reduce the size. Can accurately hit the bullet against the target.

Further, according to the third aspect, the first and the second are provided.
Similarly, according to the invention, the projectile can be prevented from being scattered unevenly due to being hindered by the outer cylinder, the projectile can be accurately hit even with a small target, and the high-pressure gas source can be set outside the warhead. Can be arranged freely.

Further, according to the fourth invention, the first and the second are provided.
According to the invention, it is possible to more reliably prevent the projectile from being hindered by the outer cylinder and scattered unevenly, and to accurately hit the projectile even with a small target.
