Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guided missile equipped with a warhead that utilizes the Neumann effect or a fragment self-forging warhead (hereinafter referred to as "Neumann effect, etc."), and particularly relates to a component of a homing head device thereof. It is something.

Conventionally, the warhead of this type of guided missile is equipped with a homing head device consisting of a shaped explosive charge, a soil, a gimbal, and a member or antenna that supports them.
The homing head device, whose role is to detect and acquire targets, tends to be located at the very front end of the guided missile in order to provide good forward visibility, and therefore shaped explosives, etc. are generally located behind it. Met.

As shown in FIG. 1, a guided missile that utilizes the Neumann effect or the like to which the present invention is applied is provided with a shaped explosive charge 1 in the trajectory section covered by a radome 6, and a shaped explosive liner 2 at the end thereof. It is pasted. In front of the explosive charge 1, a homing head device 5 comprising a gyro, a gimbal, or a structure supporting these (hereinafter simply referred to as a structure) 3 and an antenna 4 is built-in.

However, the Neumann effect of a shaped explosive means that the molten metal in the liner inside the shaped explosive is injected as a high-temperature, high-velocity jet to pierce the target, such as armored steel plates, and the fragmentation self-forging warhead is an explosion. Heavy metals that are crushed into smaller pieces are ejected at high speed in the form of a beam to pierce the target armor steel plate, etc.

However, in any case, if the front part of the shaped explosive charge 1, that is, the homing head device 5, is composed of a metal block or the like, the warhead will be deformed when it collides with the target, resulting in the formation of jets. etc. are deformed, or
Since most of the energy of the soet was absorbed by the metal lump, etc., the Neumann effect etc. in the warhead could not be fully demonstrated. In FIG. 1, reference numeral 7 indicates an impact sensor, 8 indicates a fuse, and 9 indicates a booster.

The present invention provides a tensile strength of 4 to 20 kg//+ for crushing part or all of the structure 3 and antenna 4 upon impact, in order to reduce the drop in warhead power inside the guided missile as much as possible.
The warhead is made of engineering ceramics, hardening plastics, or composites of these materials, so that when the warhead collides with the target, the structures 3, antennas 4, etc. are quickly shattered. The purpose is to provide a guided missile in which obstacles in front of the warhead are removed, the desired soot, etc., accompanying the explosion of the shaped charge reliably hits the target, and the effectiveness of the Neumann effect etc. is increased. It is something.

An example of engineering ceramics according to the present invention is α-alumina, and an example of engineering glasstics is an epoxy resin molded product, but both of these materials have a tensile strength of 4 to 20 U//IIl+2.
For a circular sample A with a diameter of 106n and a thickness of 57m placed on a support C as shown in Fig. 3, the height h
In an impact test in which a steel ball Bf with a diameter of 40 was freely dropped from a position of 10 m and directly hit the sample, sample A was
It is crushed into pieces smaller than the angle of angle.

Furthermore, with reference to the drawings, the present invention will be described based on an embodiment of a warhead that utilizes the Neumann effect.

In FIG. 2 (4), the sotte 12 of the shaped explosive liner 2, which is formed into a roughly triangular pyramid shape by the explosion of the shaped explosive charge 1, is a target object because there is no obstacle in front of the warhead. A hole 14 is drilled through the metal plate 13, but if there is a structure made of a metal lump or a homing head device 5 including an antenna in front of the warhead, the second
As shown in Figure (B), even if the warhead collides with the target, the structural members that are difficult to destroy remain in a deformed state, and the jet 12 must hit these structures and destroy or penetrate them. The jet 12 does not reach the target 13.
energy will decrease, and the Neumann effect will be significantly weakened.

When a part or all of the homing head device, especially the structure 3 and the antenna 4 are constructed using the engineering ceramics, engineering glasstics, or composites thereof according to the present invention, there is no damage caused by the collision of the warhead. The tip of the generated jet will quickly reach the target, increasing the effectiveness of the Chinoimann effect.

Now, as shown in Figure 2 (4), the warhead, which does not have structures or antennas in front of the shaped explosive charge 1, travels at a speed of 150 m/s and collides with the target object 13, causing the shaped explosive charge 1 to explode. The target, which in this case consisted of an armored steel plate with a thickness of 206 nm, was pierced by a hole 14 with a diameter of about 1 crn.

Next, as shown in FIG. 2(B), a warhead having a homing head portion consisting of a metal structure 3 and an antenna 4 was similarly run at about 150 m/sec in front of the shaped explosive charge 1, and the same as above. consists of an armored steel plate of
It stopped at a depth of about 15 crn. Furthermore, in the warhead of a guided missile having a homing head device made of engineering ceramics and engineering glasstics according to the present invention, a shaped explosive charge is detonated under the same conditions as above, as shown in FIG. 2(C). At this time, the homing head device was completely crushed 9, and at the same time, the hole with a diameter of 1 m was completely penetrated, and the intended purpose of the invention was fully achieved.

In the above embodiments, a homing head device having an antenna has been described, but similar effects can be obtained in the case of a tickle type homing head device having a lens or the like in place of the antenna. In addition, although the present invention relates to a guided projectile that utilizes the Neumann effect, etc., even if it is in front of a shell having a similar structure other than a guided projectile, it can be used as shown in Fig. 2 (B) and Fig. 2 (C).
