Description

INSENSITIVE MUNITIONS HAVING THE SAME

The present invention relates to a discharge plug for an insensitive warhead and an insensitive warhead having the same.

In order for a warhead to penetrate a target, it must have adequate penetrating force, explosive pressure, or fragmentation performance. In particular, in the case of a fortified concrete target, it is most effective to detonate after penetration, and such a warhead is called a penetrating warhead.

Since the penetrating warhead is subjected to extreme shock and acceleration while penetrating the target, the wall thickness of the warhead must be thick to secure the structural stability of the warhead, and the thin ratio, that is, the ratio of the length to diameter of the projectile must be large to improve penetration.

Penetrating warheads cause a lot of loss of life and property due to unintentional shocks or fire explosions due to user negligence. .

Warheads designed to prevent such unintended detonation are called INSENSITIVE MUNITIONS.

The bullet body of the insensitive warhead has a structure in which a hole for pressure release is formed, and the hole for pressure release is blocked with a plug.

That is, in the insensitive warhead, when the main charge filled inside is ignited and heat and pressure are generated inside the shell, the plug is removed by the heat and pressure generated inside the shell, and the high pressure internal pressure is released through the pressure discharge hole to the outside. It has a structure that can prevent the explosion of the main drug by ejection or delay the time of the explosion.

The discharge plug applied for the conventional insensitive warhead insensitivity design has a structure that is assembled to the projectile by screwing in a wedge shape.

That is, the ejection plug of the conventional insensitive warhead has a wedge shape in the form of a screw thread, and there is a problem in controlling the shape of the plug and the projectile coupling part due to the complicated shape such as the screw thread wedge collapsing during fastening, and this causes a problem in assembly There was a problem.

In addition, the discharge plug of the conventional insensitive type warhead is a major cause of increasing the overall cost of the insensitive projectile to which the discharge plug is applied due to its complicated shape. In addition, there is a problem in that complete and uniform release performance cannot be guaranteed during assembly due to complex shape and assembly instability.
