Description

{SUBMUNITION HAVE DELAYED SELF-DESTRUCT WITH INDEPENDENT PYROTECHNIC}

More particularly, the present invention relates to a jacket fuse having self-explosion means, and more specifically, a detonator operative in an impact-like manner and a delay portion detonated after a certain time elapses from a charcoal operate independently of each other, To thereby ensure a sufficient delay time.

Generally, jatang is transported from the ground through a carrier such as a shot or rocket that is fired by a gun, then released from the air and dropped to the ground.

At this time, the conveying body may be rotated or not rotated. Such a conventional charcoal is filled with a high-explosive gas for exploding the inside of the ordinary charcoal, and a penetrator for penetrating gloves such as an armored vehicle or a tank is attached to the bottom of the ordinary charcoal. Such as the penetration of gloves by the use of the dual purpose.

These charcoals are dropped into the air as they are discharged into the atmosphere due to the explosion pressure caused by the explosion of the discharge charge in the conveyance body after the discharged conveyance body reaches the predetermined upper limit. At this time, each of the magazines is dropped by the inertia that they had when they were released, and they fall down on the ground and explode. For this purpose, the jacket is equipped with a new pipe for detonating the high explosive powder. The new pipe is a mechanical pipe which is explosioned by the impact force generated when the charcoal collides with the target or the ground.

However, if the above-mentioned conventional charcoal is not sufficiently impacted at the moment of collision with the ground structure after being released from the air, the conventional charcoal can not be exploded because it is not attacked. That is, when the spark plug is dropped on a buffer zone such as a forest, snow, desert, tree or the like, a sufficient impact force is not applied to the mechanical fuse, so that the mechanical fuse can not be operated and the high explosive can not be attacked.

Such inexplicable self-destructs cause weakening of the attack power and cause explosion in the course of operations in the area, causing material damage. Therefore, most of the jar is additionally equipped with a delay fuse blowing off the jar when the mechanical fuse is not working. This delay fuse is classified into an electromechanical delayed self-destructive fuse that ignites a gunpowder in a mechanical fuse and causes self-destruction when a certain time elapses, and an electronic delayed self-destruct fuse that permits self-propagation using a power circuit and a charging circuit and a timer .

On the other hand, as a means for solving the problem of the ignition of the self-discharge, there has been introduced a technique for preventing the discharge of the spark plug. This is related to the formal delayed self-destructive firing, in which the ignition gun, the delayed gunpowder, and the connecting gunpowder are sequentially ignited through the striker using the rotational inertia force generated during the discharge of the self-propelled gun, So as to neutralize the charm. In the case of the electronic delayed self-destructive fuse, it includes a reserve battery, a power source device, an electric detonator, a timer circuit, a charging circuit, a resistance device, an electronic switch and a wind sensing device. The reserve battery is activated through a striking device operated by the air resistance generated in the process, and the printed circuit board composed of the above-described components is operated and the electric explosion-proof pipe is detonated to neutralize the charcoal.

As a prior art related to this, there is the Korean Registered Patent Publication No. 0306357 (self-destruct device of the grenade, registered on Aug. 8, 2001).

It is an object of the present invention to minimize the failure rate of the self-priming fuse by allowing the delay portion to operate independently when the self-priming fuse is released from the charcoal regardless of whether the slider is loaded or not.

Another object of the present invention is to improve the operation stability and reliability of the self-deflating fuse by preventing the detachment of the detonator in the firing range of the firing pin by moving the slider due to an impact applied to the fuse housing after the slider is mounted have.
