Description

  The present invention relates to a guided flying object that is launched from the ground surface or in the air, flies toward a target point, and releases a bullet.

  When trying to damage a wide range of targets with a guided projectile, a number of munitions have been built in the past, and rockets launched from the ground surface toward the target or bombs launched from the mother aircraft are guided to the target point. There is known a method for spreading the built-in bullets over a wide range (see, for example, Patent Document 1).

U.S. Pat. No. 4,063,508

However, there is a problem that the consequent bullets spread over a wide area in this way have a high rate of non-explosives, and the unexploded bullets will explode later and cause damage.
As an alternative bomb, it has been proposed to use a multi-EFP (Multi Exploxively Formed Penetrator) warhead in which a large number of metal liners are arranged on the circumference of the fuselage. However, this multi-EFP warhead generally has a narrow area that can be covered as compared with the method described in Patent Document 1.
In order to cover a wide area with multi-EFP bullets, it is necessary to keep the attitude of the bomb at the time of detonation perpendicular to the ground and to fire the warhead parallel to the ground at a height that can attack the target.
However, the bomb's attitude is only a few degrees, and the flying warheads are concentrated on the surface of the ground on the one hand, while the other scatters in the air and the effect is greatly reduced.

  In addition, it is possible to maintain a wide range of effects by setting the scattering angle forward of the bombs to each warhead and setting the altitude at the time of detonation high, but the bomb attitude at the time of detonation is kept perpendicular to the ground. Otherwise, the effect would be extremely reduced.

Moreover, even if the detonation is performed in an ideal posture, there is a problem that the range that can be covered by one multi-EFP bullet is much smaller than that of a conventional bomb.

  In addition, although the energy of this liner is strong, among the individual targets dispersed in the target area, there is a problem that a solid target far from the warhead detonation point cannot be neutralized.

Further, since the liner scatters in the circumferential direction centering on the bomb, there is a problem that as the distance from the center of the bomb increases, the density of the scattered liner decreases and the effectiveness decreases.

  The main object of the present invention is to solve such a problem, and provides a flying object that is equipped with a plurality of warheads and capable of damaging a target in a wide area.

  The flying body according to the present invention is equipped with a plurality of multi-EFP warheads having a plurality of metal liners arranged on the fuselage portion, and the plurality of multi-EFP warheads are discharged over the guided target.

  According to the flying object of this invention, damage can be given to a wide range of targets.
