Description

High-explosive projectile charge for medium-caliber and high-caliber ammunition and a projectile containing this charge

Field of technology

The technical solution relates mainly to the area of medium and large-caliber ammunition and preferably ammunition for so-called drones, namely the technical solution of the construction and composition of the internal explosive charge of the ammunition.

A shot or the ammunition is intended for practical use for shooting, shooting training and combat deployment.

Current state of the art

A large number of missiles and ammunition are known, for calibers from 20 mm to 230 mm of various designs, rocket ammunition, including bombs weighing from 2 kg to 500 kg, or even more.

In general, the shell of the projectile - ammunition is made of the following materials - a steel shell or other suitable metal or plastic material. The bullet charge consists of a classic explosive charge, which is manufactured either by pouring e.g. trinitrotoluene (TNT) or by pressing (hexogen-based explosive (RDX) and TNT, or other high-explosives and their mixtures, including explosive mixtures with properties for thermobaric ammunition), or by screwing a suitable mixed explosive (TNT + RDX) into the body of the ammunition, or by inserting pressed segments into the metal body of the ammunition.

The above-mentioned procedures are generally known, so there is no need for a detailed description.

Disadvantages:

In general, this ammunition containing a suitable explosive, or its mixture with another explosive, etc., does not show any disadvantages, as it is designed for the given use.

The disadvantages of these missiles for training and combat use are therefore due to the use of an explosive charge, or its homogeneous mixture (a mixture of explosives, or a mixture of explosives and powdered metals).

The essence of the technical solution

The subject of the technical solution is the high-explosive charge of the ammunition projectile of the given caliber, for training use and especially for combat use, when the charge consists of two or more components that are made of different chemical materials, but together form a single high-explosive charge of the projectile. The choice of materials and their mutual weight ratio is governed by the ballistic requirements of the projectile, the possibility of processing input materials into projectile components, the resulting projectile weight and, above all, the required final effect of the projectile in the area of impact.

The subject of the presented basic solution is a projectile consisting mainly of the projectile body, the igniter and the projectile's own explosive charge.

The explosive charge of the projectile consists of at least two chemical components, while one further consists of at least two or more chemical components.

The basic component of the charge is trinitrotoluene, and the second component of the explosive charge is the rollers, which are composed of at least two or more chemicals, and these rollers will actively participate in the reaction during the explosion of the projectile at the point of impact and the associated final effect.

- 1 CZ 37833 U1

The projectile is filled - it works in such a way that self-made rollers are fed into the projectile body and the internal volume of the projectile is subsequently filled by pouring molten trinitrotoluene, or successive tablets of high explosive and tablets made of a mixture of chemicals are inserted into the projectile body - see description.
