CZ31732U1 - An explosive filling for thermobaric ammunition - Google Patents

Description

Technical field

The technical solution concerns an explosive charge for missiles or ammunition objects with a thermobaric effect at the impact site.

BACKGROUND OF THE INVENTION

A number of compositions of explosive mixtures are known which are used as explosive charges for ammunition objects. Generally, conventional mixtures consist of explosives (TNT (trinitrotoluene), RDX (hexogen), HMX (octogen), PETN (pentrite), etc.) and powdered metal, eg AI, etc. In general, the disadvantage of all known thermobaric mixtures for missiles with the thermobaric effect is that these explosive mixtures are difficult to compress and consequently insufficient compactness of the compacting of the mixture and the consequent resistance of the compacting in the projectile at the significant acceleration that occurs during the actual firing.

The essence of the technical solution

The aim of the proposed solution is to eliminate these technical shortcomings and to create an optimal mixture that will be suitable for the assembly of missiles or ammunition objects with a thermobaric effect in the target, the compact will be compact and will be resistant to mechanical stress during the shot. According to the technical solution the molding for the compact will be well compressible, or can be pressed directly into the body of the ammunition object and the missile with this cartridge will retain all required utility parameters such as missile speed, sensitivity to initiation from the lighter object, projectile accuracy, stability. and flawless function in the corresponding weapon. Thermobaric explosive charge is a mixture consisting of common high explosives such as TNT (trinitrotoluene), RDX (hexogen), HMX (octogen), PETN (pentrite) and others, powdered metals AI, Ti, Cu, Fe and binder TPFE (teflon), which, in addition to the binder mixture function, provides an increase in the ignition and ignition effect at the target site due to combustion.

Examples of technical solutions

Example 1

% TNT (trinitrotoluene) 50 wt.

- Al 30 wt.

- PTFE (Teflon) 20 wt.

In the preparation of the mixture, the components are dry blended and as such the prepared mixture is gradually fed into a press set and subsequently the molded is laboratory-loaded into the projectile body. When firing a missile at the target, the missile exhibits the desired effects and at the same time has an increased ignition and ignition effect at the target due to PTFE (Teflon) burning.

Example 2

- RDX (hexogen) 50 wt.

- Al 30 wt.

- PTFE (Teflon) 20 wt.

- 1 GB 31732 U1

Example 3

TNT (trinitrotoluene) -AI

- PTFE (Teflon)

Example 4

- RDX (hexogen)

-AI

- PTFE (Teflon)

Example 5

- RDX (hexogen)

-Cu

- PTFE (Teflon)

Example 6

- RDX (hexogen)

-AI

% PTFE (Teflon) wt. 30 wt. 30 wt.

% wt. 20 wt. 50 wt.

% wt. 10 wt. 70 wt.

% wt. 20 wt. 50 wt.

In preparing the mixture, the components are dry blended and as such the prepared mixture is gradually metered into the projectile body where it is pressed to the desired density. When firing a projectile by hitting the projectile on the target, the projectile exhibits the desired effects and at the same time has an increased ignition and ignition effect at the target site due to PTFE (Teflon) burning.

Industrial applicability

The explosive charge of the present invention is suitable for use in thermobaric ammunition for infantry weapons. Production of this explosive charge is feasible on conventional equipment of manufacturers of pyrotechnics and ammunition.
