DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flying object against reactive armor.

[0002]

2. Description of the Related Art As a flying object against reactive armor, a system called a tandem warhead is well known, and is widely used for an armor target. The tandem warhead has a configuration in which a forming bullet 2 called a pioneer warhead is arranged in front of a main forming bullet 1 as shown in FIG. After the protective force of the reactive armor 3 in front is reduced by the action of the above, the main bullet 1 is actuated to achieve the penetration of the main armor 4 without being greatly reduced by the reactive armor 3 It is.

[0003] As a method of depriving the reactive armor 3 of the protective armor with the molded bullet 2 of the pioneer warhead, a method of exploding the reactive armor 3 (prior art is disclosed in Japanese Patent Laid-Open No. 4-36).
No. 3600 is disclosed in FIG. ) And without exploding. As shown in FIG. 5, the tandem warhead of the type in which the reactive armor 3 is detonated by the precursor warhead 2 increases the power of the precursor warhead 2 in order to detonate various reactive armor. There is a need. This complicates the design for matching the morphing bullet 2 of the pioneer warhead with the homing device and the main molding bullet 1, especially when applied to a homing type flying object.

[0004] A tandem warhead that does not detonate the reactive armor 3 does not detonate the explosive of the reactive armor 3 with a metal jet of a molded bullet 2 of a pioneer warhead as shown in FIG.
This is intended to prevent the operation of the reactive armor 3 by partially scattering and passing the metal jet 5 of the main forming bullet 1 through the area. However, if the power of the pioneer warhead 2 is increased in an attempt to increase the explosive scattering area of the reactive armor 3, the reactive armor 3 will explode, and there is an upper limit to the scattering area that can be taken. For this reason, the explosive scatter area is insufficient for the large main molded bullet 1 aimed at improving the penetration force of the main armor 4, making it difficult to apply the explosive.

[0005] As another flying object opposed to the reactive armor 3, there is a so-called semi-armored type shown in FIG. In this, a nose tube 6 is provided in front of the main forming bullet 1 and the nose tube 6 penetrates the reactive armor 3.
After Toru, it is to the hollow portion and the passage of the metal jet 5 of the main molding bullet 1. However, the semi-piercing method is difficult to design for reactive armor of various shapes, and it is necessary to give the hollow cylindrical nose tube 6 sufficient strength to penetrate the reactive armor 3, The dimensions and mass increase. In addition, this method
For a homing type flying object, it is structurally difficult to align the homing device with the nose tube 6.

[0006]

Accordingly, the present invention can reduce the size and mass of a tandem warhead compared to a pioneer warhead, and can be applied to a homing type flying object. The aim is to provide a simple, low cost anti-armored vehicle.

[0007]

An anti-armored flying object according to the present invention for solving the above-mentioned problems penetrates a molded bullet through a main armor.
And the front part of the projectile is placed in front of the warhead.
The armored flying speed of the flying object
Use it to detonate reactive armor with kinetic energy
A small penetrator inside the front part
It is characterized by being arranged in. When the speed of the above-mentioned anti-armored flying object is substantially lower than Mach 3 around Mach 3, it is preferable that the penetrator is a pyrotechnic containing a built-in explosive. When the speed of the above-mentioned anti-armored flying object is a supersonic speed exceeding Mach 3, it is preferable that the penetrator does not include explosives and is a strength part which also serves as a part of the front part of the shell. It is preferable that the front part of the shell of the anti-armored vehicle has a fragile structure.
When the anti-armored flying object is a homing type, it is preferable that the front part of the projectile is a homing device.

[0008]

As described above, the anti-armored flying object of the present invention uses a molded ammunition as a warhead penetrating the main armor, and forwards the ammunition in front of the warhead.
In the anti-armored vehicle where the components are placed,
Utilize the impact speed of the body to react with kinetic energy
The small size of the penetrator to detonate the Restorative armor, the bullet body
Since it is located inside the front part , in its use , the penetrator collides with and penetrates the reactive armor of the armor target to detonate the reactive armor.
Utilizing the momentum of the front part of the projectile, the protective force of the reactive armor is reduced. Then activate the molding bullets,
Penetrates the main armor without significant loss of power.

When the velocity of the anti-armored flying object of the present invention is lower than Mach 3, since the penetrator is a pyrotechnic with a built-in explosive, etc., when the penetrator collides with the reactive armor and penetrates , the explosion occurs. This detonates the reactive armor and reduces the protection of the reactive armor. In the case the speed of the anti-armor projectile supersonic exceeding Mach 3 of the present invention, the penetrator does not contain explosives, since the intensity component serving also as a part of the ammunition body front-end module, is penetrator collides with the reactive armor, when penetration to detonate reactive armor by the impact, and to reduce the protective power of the reactive armor.
When the anti-armored flying object of the present invention is a homing type, a homing device can be used as a front part of the shell, that is, using the mass and density of the homing device,
The protective force of reactive armor can be reliably reduced. Therefore, the reactive armor protection is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an anti-armored vehicle according to the present invention will be described with reference to the drawings. FIG.
A bullet front component 12 is arranged in front of a molded bullet 11, which is a warhead penetrating the main armor ,
A small penetrator 13 is disposed inside the front part 12 of the elastic body. The operating principle of the anti-armored flying object 10 will be described with reference to FIGS.
As shown in FIG. 5, when the bullet front component 12 incorporating the high-strength penetrator 13 hits the reactive armor 15 attached to the main armor 14 at a high speed, the bullet front component 1
2 is sequentially destroyed from the front by the reactive armor 15 as shown in FIG. 2B, but the penetrator 13 penetrates directly into the reactive armor 15 with its own kinetic energy, and is exploded by impact force or explosion using gunpowder. The reactive armor 15 is detonated, causing the two plates 16, 17 to fly in opposite directions. Among the plates of the reactive armor 15, the plate (F-plate) 16 which flies in the direction of the main armor 14 flies at a predetermined speed,
2c of FIG. 2
As shown in (1), it collides with the main armor 14 and loses its intended protection against the molded bullets 11. The plate (B-plate) 17 flying in the direction of the bullet is a front component 12 of the bullet.
The flying speed decreases due to the impulse associated with the destruction of the ship, and the protective force is greatly lost. At this point, the molding bullet 11 is activated,
The metal jet 18 generated by the molding bullet 11 is shown in FIG.
As shown in (1), the main armor 14 penetrates without being greatly disturbed by the reactive armor 15.

FIG. 3 shows an example in which the velocity change of the plate (B-plate) 17 flying in the direction of the above-mentioned bullet is calculated. In FIG. 3, after 200 μsec, the speed is reduced to within ± 20% of the initial speed. It is known that the protection performance of the B-plate 17 against the metal jet 18 of the molded bullet 11 largely depends on its flying speed,
The reduction in speed in the above example means a large reduction in protection.
As described above, the anti-armored flying object 10 of the present invention is technically characterized by two points: the detonation of the reactive armor 15 by the penetrator 13 and the reduction of the flying speed of the B-plate 17 by the projectile component 12. Is the point.

The penetrator 13 for detonating the reactive armor 15 is a pyrotechnic which incorporates explosives and the like when the speed of the anti-armored flying object 10 is less than Mach 3 around the boundary of Mach 3. When the speed of the anti-armored flying vehicle 10 is supersonic speed exceeding Mach 3, it does not include explosives and has a strength that also serves as a part of the bullet front component 12. The penetrator 13 is configured as a part of a component and is detonated by an impact force when the reactive armor 15 is penetrated. The penetrator 13 having such a configuration can be made smaller and lighter than a tandem warhead shaped bullet. Factors contributing to the reduction of the flying speed of the B-plate 17 are mainly related to the speed, density, size, and strength of the front component 12 of the bullet, in addition to the shot angle.
These are related to the optimal operation timing of the molding bullet 11,
As for the operation timing of the molded bullet 11 in the anti-armored flying vehicle 10 of the present invention, the protection force of the reactive armor 15 cannot be ignored if it is too early similarly to the case of the tandem warhead, and if it is too late, the disturbance relating to the power of the warhead will be warheaded. May affect the operation of B- of the reactive armor 15 shown in FIG.
As can be seen from the calculation example of the deceleration of the plate 17, if the reactive armor 15 is allowed to pass through the metal jet 18 of the molded bullet 11 after the required time has elapsed (the time required for the metal jet 18 to pass through is several tens of microseconds), the reactive armor is used. 1
5 can be regarded as sufficiently low, and during this time, it is easy to prevent the power of the molded bullet 11 from being reduced by external disturbance.

When the anti-armored projectile 10 of the present invention is of the homing type, a homing device can be used for the front part 12 of the projectile , so that the penetrator can be used as a homing type.
Armor 15 using the mass and density of the
Can be reliably reduced to several times. Obedience
The reactive armor 15 has reduced protection
Detonate the molded bullets 11 and penetrate the main armor 14
You.

[0014]

As can be understood from the above description, the anti-armored flying object of the present invention utilizes the impact speed of the flying object inside the front part of the projectile arranged in front of the molded bullet. Exercise energy
Since placing a small Penetore <br/> data to detonate reactive armor in Energy, Reactive armor of anti-armor targets
Can be detonated by colliding and penetrating the penetrator at the front of the shell
Reactive armor protection using component momentum
Can be reduced, followed by a significant decrease in power due to molding bullets
Without penetrating the main armor. Therefore, the function and performance are not impaired by the shooting angle condition, and the restriction of the operation by the impact condition is small. In the anti-armored flying object of the present invention, the penetrator is a pyrotechnic having a built-in explosive, etc., when the speed is less than Mach 3 around the boundary of Mach 3, and when the speed is supersonic speed exceeding Mach 3, the penetrator is used. In addition, since it does not include explosives and is a strength component that also serves as a component of the front of the body, the protective force of the reactive armor can be reliably reduced. Further, the anti-armored flying object of the present invention utilizes the homing device for the front part of the projectile , so that the penetrator uses the mass and density of the homing device to increase the protective force of the reactive armor. It can surely be reduced to a fraction.
