DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying object protection system for protecting an incoming flying object by using an intercepting flying object.

[0002]

2. Description of the Related Art In recent years, there has been an increasing trend in Japan to develop a flying object defense system for intercepting a flying object flying into the atmosphere. Conventionally, as this type of flying object defense system, intercepting flying objects have been used to counter incoming flying objects, but the success rate of interception is high because high-speed flying objects need to collide with each other. It was low.

[0003] Therefore, recently, a method in which a large number of pellets are mounted on the warhead of an intercepting projectile and the pellets are ejected to a flying projectile like a shotgun, or a method in which an umbrella is deployed by a spiral spring. By taking it, the probability of colliding with the flying projectile was increased.

[0004]

However, the conventional flying object defense system as described above has the following problems. In the case of the pellet discharging method, there is a problem that the distance is not so long, the range as a barrage is narrow, and the effect is only given for a short time. On the other hand, in the method of deploying umbrellas, expanding the range of umbrellas increases weight,
There was a problem that the intercepting flying object became large.

The present invention has been made in consideration of the above points, and has as its object to provide a flying object defense system having a high intercept success rate without increasing weight.

[0006]

In order to achieve the above object, the present invention employs the following constitution. The flying object defense system according to claim 1,
In a flying object defense system for defending with an intercepting flying object having a warhead, the intercepting flying object is mounted on each of a plurality of first balls shot from the warhead and a plurality of the first balls,
The second shot that is shot with a time difference to the shot of the first ball
And a ball.

Therefore, in the flying object defense system of the present invention, since the second ball scatters with a delay after the first ball scatters from the warhead, a barrage can be formed over a wide range and for a long time. In this case, the success rate of interception colliding with the flying object can be increased. Further, in the flying object defense system of the present invention, since the first ball and the second ball are released from the warhead, it is possible to reduce the size and weight of the system in which the deployed umbrella is mounted.

Further, the flying object defense system according to claim 2 is characterized in that in the flying object protection system according to claim 1, a plurality of the second balls are mounted inside the first ball. It is.

Therefore, in the flying object defense system of the present invention, the volume of the warhead required by the second ball can be reduced, so that the size and weight can be further reduced.

According to a third aspect of the present invention, there is provided the flying object protection system according to the first or second aspect, wherein the warhead is provided with a detecting device for detecting a position of the flying projectile. It is characterized by having.

Therefore, in the flying object defense system according to the present invention, the position of the flying object flying until the first ball and the second ball are released can be detected, thereby forming a barrage with high accuracy with respect to the trajectory of the flying object. be able to.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a flying object defense system according to the present invention will be described below with reference to FIGS. FIG. 1 is a schematic configuration diagram of a flying object defense system for a three-stage flying object 1. The defense system includes radar stations 2 and 3 provided on the ground for measuring the position and speed of a flying object 1 flying, an intercepting flying object 4, and an intercepting flying object 4
And a mobile launcher 5 that emits the light.

The interceptor 4 has a configuration in which a multi-stage solid rocket 6 is provided with a warhead 7. As shown in FIG. 2, inside the warhead 7, a radar 8 as a detection device for detecting the position of the flying object 1 and an ITV (Industrial Telev.
ision) A camera 9, an attitude control device 10, and a controller 11 are mounted. The controller 11 controls the attitude control device 10 based on the detection results of the radar 8 and the ITV camera 9.

A plurality of large balls (first balls) 13 are mounted inside the warhead 7 together with an explosive 12 which is detonated under the control of the controller 11. Inside each large ball 13, a plurality of middle balls (second balls) 14 having a smaller diameter than the large ball 13 are mounted together with an unillustrated explosive. Each large ball 13 has a squib (not shown) connected to an internal gunpowder.
Are provided to be exposed to the outside.

Further, inside each middle ball 14, a plurality of small balls having a diameter smaller than that of the middle ball 14 (second
A ball 15 is mounted, and a firing wire (not shown) exposed to the outside is also connected to this explosive. The small ball 15 has a structure having a large number of protrusions on the surface like confetti.

The operation of the flying object defense system having the above configuration will be described below. As shown in FIG. 1, when the launched flying object 1 is detected by the radar stations 2 and 3, the intercepting flying object 4 is launched from the mobile launcher 5. The intercepting flying object 4 approaches the flying object 1 with the propulsion of the solid rocket 6 based on the position and speed of the flying object 1 detected by the radar stations 2 and 3.

Then, when the warhead 7 is separated from the solid rocket 6 in the atmosphere, the controller 11
By controlling the attitude control apparatus 10 using the detection result of the ITV camera 9 and the warhead 1a of the flying object 1 that re-enters the atmosphere from outside the atmosphere (see FIG. 1), for example.
Approach. When approaching the warhead 1a, the controller 11 detonates the explosive 12 and scatters the large ball 13 in a scattered state.

Here, the large ball 13 is exploded with the explosion of the gunpowder 12.
Is fired, and after the shot of the large ball 13, each large ball 13 explodes with a time difference and the middle ball 14 is shot. In addition, the explosion ignites the fuse of the middle ball 14, and after the shot of the middle ball 14, each middle ball 14 explodes with a time difference and the small ball 15 is shot. That is, as shown in FIG.
The medium ball 14 is scattered from the large ball 13 scattered in the scattering state, and the small ball 15 is scattered in all directions from the middle ball 14 in the scattered state.
A large and high-density barrage can be uniformly formed with respect to a.

In the flying object defense system of the present embodiment,
Since the middle ball 14 and the small ball 15 are shot with a time difference with respect to the shot of the large ball 13, it is possible to form a wide range and high density barrage, and the probability of intercepting the small ball 15 by colliding with the warhead 1 a is reduced. It can be dramatically improved. In particular, since the small ball 15 has a projection, it can easily bite into the colliding warhead 1a, and can be easily broken or damaged to deflect the trajectory. Moreover, in the present embodiment, the controller 11 controls the radar 8 and the I
Since the position of the warhead 1a is detected using the TV camera 9, the shot can be shot closer to the warhead 1a, so that the probability of intercepting the warhead 1a can be further increased.

Further, in the flying object defense system of the present embodiment, since the large ball 13, the middle ball 14, and the small ball 15 are used, it is possible to prevent the weight from increasing as in the method of expanding the umbrella. In particular, since the small ball 15 is mounted inside the middle ball 14 and the middle ball 14 is mounted inside the large ball 13,
The volume of the warhead 7 required by the middle ball 14 and the small ball 15 can be reduced, and the size and weight of the warhead 7 can be reduced.

In the above embodiment, the large ball 13
Although the configuration was such that a fuse wire was used when the middle ball 14 and the small ball 15 were shot with a time difference for the shot, the present invention is not limited to this. For example, a configuration in which a timer or the like is mounted may be used. . In the above-described embodiment, three types of balls are shot from the warhead 7. However, any number of two or more types may be used. Furthermore, if the middle ball 14 and the small ball 15 are shot with a time difference with respect to the shot of the large ball 13, each ball does not necessarily have to be mounted inside the large ball 13.
